Joseph and Barbara Pukt
v.
Civil No. 14-cv-215-JD
Opinion No. 2016 DNH 085
Nexgrill Industries, Inc.
O R D E R
Joseph and Barbara Pukt brought suit against Nexgrill
Industries, Inc., alleging claims that arose from damage to
their property after a grill manufactured by Nexgrill caught
fire.
Nexgrill moves to exclude the testimony of two of the
Pukts’ expert witnesses, and the Pukts object.
The Pukts move
to exclude the testimony of two of Nexgrill’s expert witnesses,
and Nexgrill objects.
Nexgrill also moves to strike an
affidavit submitted by the Pukts in support of their reply to
Nexgrill’s objection to their motion to exclude expert opinion.
The Pukts object to that motion.
Background
Joseph Pukt received the Charmglow grill that is the
subject of this case as a Father’s Day gift from his family in
2005.
On July 1, 2012, the Pukts’ son, Jonathan Alger, cooked
on the grill.
Soon after he was through cooking, the grill
caught fire, and the fire spread to the deck and house, causing
extensive damage.
The Pukts’ Charmglow grill operated with a removable
propane gas cylinder located in a cabinet below the grill
burners that provided gas to the burners through a hose.
The
grill had a removable grease tray that was located below the
cooking area and above the grill cabinet.
The propane cylinder
used in the grill had a pressure relief valve (“PRV”) to vent
propane if pressure in the cylinder reached 375 pounds per
square inch, which would occur if the propane in the cylinder
reached 160 degrees.
When propane is released through the PRV,
it makes a hissing sound.
The grill had a regulator that attached to the propane
cylinder and the hose.
The regulator had an excess flow valve
(“EFV”) that was intended to restrict the flow of propane out of
the cylinder in the event of a hose failure.
At a certain level
of gas flow, the plastic nut in the regulator is designed to
melt and activate a “back-check” that obstructs the flow of
propane from the cylinder.
The propane cylinder in the Pukts’ grill had last been
replaced two weeks before the fire.
Joseph Pukt made sure at
that time that the hose was not touching the underside of the
grill or the grease tray.
2
The Consumer Product Safety Commission (“CPSC”) issued a
safety recall for the Pukts’ model of the Charmglow gas grill in
September of 2005.
The recall states:
“The hose connecting the
propane tank with the manifold may run up too close to the
firebox.
The heat from the firebox could damage the hose.
hose can leak gas.
The
A fire or explosion may occur.”
The parties dispute the cause and origin of the Pukts’
grill fire.
The experts all represented that they used the
method provided by the National Fire Protection Association,
NFPA 921, Guide for Fire and Explosion Investigations, but
arrived at different conclusions.
Standard of Review
To testify as an expert, a witness must be qualified to do
so “by knowledge, skill, experience, training, or education.”

A qualified expert witness “may testify in
the form of an opinion or otherwise” if the witness’s
“scientific, technical, or other specialized knowledge will help
the trier of fact to understand the evidence or to determine a
fact in issue;” if “the testimony is based on sufficient facts
or data;” if “the testimony is the product of reliable
principles and methods;” and if “the expert has reliably applied
the principles and methods to the facts of the case.”

Motion to Strike Affidavit
Nexgrill moves to strike the affidavit of Kenneth Mayer,
who is an expert witness for the Pukts, that was submitted in
support of the Pukts’ reply to Nexgrill’s objection to the
Pukts’ motion to exclude Nexgrill’s experts’ opinions.1
Nexgrill
argues that part of paragraph three in the affidavit, which
pertains to the location of the grease tray in the grill after
the fire, provides an opinion that was not previously disclosed
by the Pukts and that is based on mere speculation.
Nexgrill moves to strike all of Mayer’s affidavit although
it cites only part of paragraph three as containing undisclosed
expert opinion.
1
4
The challenged statements in Mayer’s affidavit were
submitted to show that the opinion of Nexgrill’s expert, Jason
Kramarczyk, should be excluded because he failed to consider
material evidence, including the grill artifacts.
Kramarczyk
stated that in his opinion the location of the grease tray in
the grill was unknown and that it could have been open, which
might have caused the fire.
Mayer provided his affidavit based
on his examination of the grill after the fire and photographs
of the grill taken by Nexgrill’s expert witness, Alan Dudden.
Paragraph three of the affidavit states (with the challenged
part underlined):
The sloped side of the bowl assembly, which was
impacted by the fire extinguisher valve when it
exploded upwards, is engaged with the full length of
the grease tray. When the fire extinguisher exploded,
the impact caused the sheet metal to distort. In
turn, the grease tray and bowl assembly were locked
together in the same condition that existed at the
time of the explosion, as depicted in the photos.
Thus the grease tray was fully inserted at the time of
the explosion, as depicted in the photos.
In their objection, the Pukts do not dispute that Mayer did
not disclose his opinion about the location of the grease tray.
They argue instead that the physical evidence, the remains of
the grill, show that Kramarcyzk’s opinion is unsupported and
wrong.
They also state without citation to authority or other
explanation that “the affidavit is undoubtedly fair response to
5
the [sic] Kramarczyk’s new disclosure of this grease tray
hypothesis at his deposition.”
To the extent Mayer’s opinions about the location of the
grease tray were not properly disclosed, they cannot be used in
support of the Pukts’ motion to exclude Kramarcyzk’s opinion.
Fed. R. Civ. P. 37(c)(1).
The court does not decide at this
time whether the opinion in paragraph three would be admissible
at trial.
Paragraph three will not be considered for purposes
of the Pukts’ motion to exclude Kramaczyk’s opinions.
Therefore, the motion to strike is granted to the extent that
the opinion in paragraph three is not considered for purposes of
the pending motion to exclude expert opinion.

Nexgrill’s Motion to Exclude Expert Testimony
Nexgrill moves to exclude the opinions of Kenneth Mayer and
David Wheeler, the Pukts’ expert witnesses, that the fire was
caused by the defect in the grill that required the recall.
support, Nexgrill contends that the opinions of Mayer and
Wheeler about the cause of the grill fire are not reliable or
relevant.
The Pukts contend that both experts’ opinions meet
the requirements of Rule 702.

A.
Reliability
As provided in Rule 702, an expert’s opinion is reliable if
it is based on sufficient facts and data, if the expert used
reliable principles and methods, and if the expert reliably
applied the principles and methods.
In contrast, an opinion is
not reliable if it is based on conjecture or speculation or if
it lacks a sufficient factual foundation.

1996)).
Generally, disputes about the factual bases of an
expert’s opinion affect the weight and credibility of the
opinion but not its admissibility.

Kenneth Mayer
Kenneth Mayer works as a forensic engineer for Atlantic
Professional Services in Nutley, New Jersey.
He has a
bachelor’s degree in computer science and master’s degrees in
electrical engineering and computer science.
professional engineer in New Jersey.
Mayer is also a volunteer
firefighter and has a fire official’s license.
7
He is a licensed
He has
investigated the cause and origin of many fires and has
investigated twelve fires involving gas grills.
Nexgrill does
not challenge Mayer’s qualifications to give expert opinion
testimony in this case.
For his investigation of the Pukts’ grill fire, Mayer
reviewed the NFPA 921 Guide for Fire and Explosion
Investigations, the 2008 NFPA Fire Protection Handbook, other
books on fires and ignition of fires, deposition transcripts,
Nashua Fire Rescue’s reports on the fire at the Pukts’ property,
CPSC documents, a contemporaneous video of the fire, and other
documents.
Mayer also interviewed Joseph Pukt.
He examined the
remains of the propane gas cylinder and the grill that were
involved in the fire.
After considering and ruling out the possibility that heat
from the grill ignited the deck railing to cause the fire, Mayer
concluded that the fire started inside the grill.
He also
concluded that the location of the grill on the deck was
irrelevant to the extent of the fire.
In Mayer’s opinion, the
fire started because of the defect in the grill that allowed the
gas hose to come into contact with the underside of the grill
and melt.
Once the hose melted, the propane escaped freely and
ignited.
In Mayer’s opinion, the EFV on the cylinder failed,
8
because the EFV should have stopped the flow of propane.
The
heat in the cabinet caused the propane cylinder to reach 160
degrees, which triggered the PRV to let off propane, which
burned.
Therefore, Mayer concluded, the ignition of the fire
was due to the gas hose contacting the underside of the grill’s
firebox because of the latent defect identified in the recall.
Mayer also did a risk analysis of the grill.
He found that
Nexgrill did not properly analyze the hazards or assess the
risks in the use of the grill and failed to minimize risks by
design.
Mayer concluded that the Charmglow grill was not
designed to minimize the potential fire hazard caused by
foreseeable use of the grill.
Mayer also found that Nexgrill
violated the CPSC requirements and other federal standards
regarding product defects and adequate safety warnings.
Mayer stated that he followed the methods and procedures
provided by NFPA 921.
Based on his investigation, he found that
the Pukts’ grill was manufactured with a latent defect because
the regulator hose could come in contact with the hot grease
drawer or the grill’s firebox and that the latent defect caused
the fire in the Pukts’ grill.
He also concluded that the
location of the grill on the deck and other propane cylinders on
the deck did not cause the fire.
9
Mayer prepared a supplemental report to respond to a report
prepared by Gas and Mechanical LLC about the causes and origins
of the Pukt’s fire.
Mayer noted deficits and errors in the
opinions expressed in that report.
He concluded that his
original opinions remained unchanged that the fire was caused by
the defect in the grill which caused the hose to melt and
rupture.
He concluded that if the hose had not ruptured, the
fire would not have happened, and if the EFV on the regulator
had functioned there would only have been a small fire.
2.
David Wheeler
David Wheeler works for New England Fire Cause & Origin
(“NEFCO”) located in Rochester, New Hampshire.
He has fire
science and criminal justice degrees from New Hampshire
Vocational Technical College, which later became Lakes Region
Community College.
Wheeler was a New Hampshire state trooper
and served as lead investigator on the arson task force.
He has
worked for NEFCO for six years and has investigated a number of
grill fires.
Nexgrill does not challenge Wheeler’s
qualification to give his expert opinion.
Wheeler inspected the fire scene at the Pukts’ house the
day after the fire and interviewed Joseph and Barbara Pukt.
In
addition, Wheeler considered fire scene photographs, the Nashua
Fire Department report, the grill’s installation manual, the
10
deposition of Allen W. Dudden taken in another grill fire case,
the Gas and Mechanical Laboratories Inc. report, the deposition
of New Hampshire Fire Marshal Mark Rapaglia, the depositions of
the Pukts, the deposition of a neighbor, and a YouTube video of
the fire before the fire department arrived.
Wheeler ruled out
as possible causes of the fire the electrical wiring in the
house and heat from the grill igniting the deck.
He also
considered the grill recall materials.
Wheeler concluded that the fire started in the lower
cabinet of the grill and that it was an accidental event.
In
his opinion, the location where the fire started “is consistent
with a failure of the gas hose that came into contact with a hot
object within the grill cabinet/assembly.”
Wheeler relied on
Mayer’s report for details about the failure of the hose.
3.
Nexgrill’s Challenges
Nexgrill contends that the opinions provided by Mayer and
Wheeler are not admissible because they did not test the Pukts’
burned grill, did not test an exemplar grill, and did not
examine the hose, which was destroyed in the fire.
Based on
those perceived deficiencies, Nexgrill argues that their
opinions are based on speculation without factual foundation.
Nexgrill also contends that their opinions that the hose
contacted the underside of the grill are contrary to the
11
evidence that when Joseph Pukt installed the cylinder, two weeks
before the fire, the hose was not touching the underside of the
grill and that the orientation of the cylinder did not change.
Nexgrill challenges Mayer’s opinion about when the PRV was
triggered based on evidence of when various witnesses heard a
hissing noise from the grill.
Mayer and Wheeler followed the procedure of NFPA 921, which
Nexgrill does not dispute is the appropriate method for
investigating the fire.2
Nexgrill’s criticisms do not show that
the opinions of Mayer and Wheeler are unreliable.
Instead,
Nexgrill’s raises factual issues that may be subjects for crossexamination to test the credibility and weight of those
In its reply, Nexgrill contends that Mayer and Wheeler rely
on speculation and possibility in violation of NFPA 921 and
violated the NFPA standard which provides that a specific
ignition source cannot be determined based on a “negative
corpus,” that is, without evidence to support it. Ordinarily,
the court does not consider arguments raised for the first time
in a reply. LR 7.1(e)(1); SignalQuest, Inc. v. Chou, 2016 WL
738209, at *5 (D.N.H. Feb. 23, 2016).
The Pukts, however, addressed those arguments in their
surreply. Regardless of whether the 2011 or 2014 version of
NFPA 921 would apply here, Mayer and Wheeler identified
sufficient evidence to support their opinions to avoid the
negative corpus issue. To the extent Nexgrill disputes the
evidentiary basis for the opinions, that is an issue for crossexamination.

Therefore, the opinions of Mayer and Wheeler are not
excluded for lack of reliability.3

An opinion must address facts that are at issue in the case
to be relevant.

F.3d 472, 476 (1st Cir. 1997).
The expert’s analysis and

opinion adequately addresses the issue to be decided.4
Samaan v.
St. Joseph Hosp., 670 F.3d 21, 32-35 (1st Cir. 2012).
Nexgrill contends that Mayer’s opinions are not relevant
because Mayer considered a grill fire in another case, the Dunn
case, which involved a different model grill.

Nexgrill also argues for the first time in its reply that
the opinions of Mayer and Wheeler should be excluded under
Federal Rule of Evidence 403 because the opinions are more
unfairly prejudicial than probative. Even if that theory had
been properly raised, Nexgrill has not shown that the opinions
of Mayer and Wheeler must be excluded on that basis.

As an example, the Supreme Court has explained that if the
issue in the case is whether the night in question was dark,
expert testimony about the phases of the moon would be relevant.
Daubert v. Merrell Dow Pharms., Inc., 509 U.S. 579, 591 (1993).
On the other hand, if the issue in the case is what happened
during that night, “evidence that the moon was full on a certain
night will not assist the trier of fact in determining whether
an individual was unusually likely to have behaved irrationally
on that night.” Id.

information he considered in arriving at his opinion on the
cause of the fire.
Mayer mentions the Dunn case in a footnote
and acknowledges that the fire involved a different model grill
made by Nexgrill.
Mayer mentioned the Dunn case to consider the
similarity of the resulting fire damage and the failure of the
EFV in that case.
As such, Mayer’s brief consideration of the Dunn case does
not make his opinion on causation irrelevant.
II.
Pukts’ Motion to Exclude Expert Testimony
The Pukts move to exclude the opinions of Nexgrill’s expert
witnesses, Allen Dudden and Jason Kramarczyk.
The Pukts contend
that those opinions are not reliable because of a lack of
supporting facts, because the opinions are inconsistent, because
Dudden changed his opinion during his deposition, and because
the experts did not follow their stated methodology.
A.
Allen Dudden
Allen Dudden works for Gas and Mechanical LLC in Missoula,
Montana.
As stated in his resume provided with his report,
Dudden is a “Professional Engineer in the State of California in
the field of Safety (SF 1434)” and a “Certified Gas Engineer
(CGE 093).”
He has worked at Gas and Mechanical LLC through his
14
career.
Nexgrill hired Dudden to investigate grill fires in
2005 related to the recall issues, and then retained him to
serve as an expert in this case.
The Pukts do not dispute that
he is qualified to provide expert opinions in this case.
In making his report, Dudden reviewed ANSI standards,
Canadian Standards Association test reports on Nexgrill grills,
Mayer’s and Wheeler’s reports, the Nashua Fire Department report
on the Pukts’ fire, “Fire Video from Face book,” depositions,
and other documents.
for the fire:
Dudden considered several possible causes
the propane cylinder valve, a grease fire in the
grill, improper replacement of the grill burners, a spider or
bug in the “venturi” of the burner, and the latent defect of the
hose contacting a hot surface of the grill.
Dudden concluded
that he could not determine what caused the fire, but he also
stated that the gas hose was not touching the bottom of the
grill or the grease drawer.
B.
Jason Kramarczyk
Jason Kramarczyk works for Unified Investigations &
Sciences, Inc., which is located in Nashua, New Hampshire.
He
has a bachelor of science degree in mechanical engineering and a
master of science degree in fire protection engineering from
Worcester Polytechnic Institute.
He previously worked for a
fire investigation company in California, an engineering company
15
in Colorado, and an investigations and engineering company in
Colorado.
He is a licensed fire protection engineer.
The Pukts
do not challenged Kramarczyk’s qualifications.
In his report, Kramarczyk says that his company, Unified,
undertook the assignment but does not explain what he did or
what may have been done by others.
He states that the fire
scene was examined in August of 2012, research was done on the
history of the grill and recall information, an exemplar grill
was examined, and documents were reviewed, including
photographs, depositions, the Nashua Fire Department report, the
grill’s use and care guide, Dudden’s report, and other reports
and documents.
Kramarczyk concluded that the cause of the fire
is undetermined.
C.
The Pukts’ Challenges
The Pukts contend that the opinions of Dudden and
Kramarczyk that the cause of the fire cannot be determined do
not meet the reliability requirement of Rule 702.
In support,
the Pukts argue that Dudden and Kramarczyk contradict each
other, that Dudden changed his opinion during his deposition,
and that both experts failed to consider CPSC documents and
Nexgrill’s discovery responses.
Nexgrill responds that Dudden
and Kramarczyk followed the NFPA 921 procedure for fire
investigation.
16
Discrepancies and contradictions within and between the
experts’ opinions provide fertile grounds for cross-examination
on the weight and credibility of the opinions.
See West v. Bell
Helicopter Textron, Inc., 967 F. Supp. 2d 479, 487 (D.N.H.
2013).
Those issues, however, do not necessarily undermine the
expert’s methodology used to reach the opinion.
See Campos v.
Safety-Kleen Sys., Inc., 98 F. Supp. 3d 372, 381 (D.P.R. 2015).
Therefore, the identified discrepancies and contradictions do
not require exclusion of the experts’ opinions.
The Pukts also argue that Dudden and Kramarczyk failed to
follow the methodology provided by NFPA 921 and required under
Rule 702 by failing or refusing to consider information and
documents about other incidents involving Nexgrill grills.
Specifically, the Pukts cite NFPA 921 § 4.3 and § 19.2 and
represent that those sections require an investigator to “gather
all possible data, create a hypothesis, and then test that
hypothesis.”
They also assert that because Rule 702 requires an
expert opinion to be “based on sufficient facts or data” an
expert opinion must be excluded if the expert failed to consider
important information.
Dudden and Kramarczyk provided facts and data, which they
relied on, to support their opinions that the cause of the
Pukts’ fire is undetermined.
Any weaknesses in the factual
17
bases of the experts’ opinions can be addressed through crossexamination.
See Milward, 639 F.3d at 22.
Therefore, the
experts’ failure to consider information about other Nexgrill
fires does not require that the opinions be excluded due to a
lack of reliability.
Conclusion
For the foregoing reasons, the defendant’s motion to strike
(document no. 61) is granted only to the extent that the
challenged opinion in paragraph three of the affidavit is not
considered for purposes of the pending motion to exclude expert
opinion.
The parties’ motions to exclude expert opinion
testimony (documents 42 and 48) are denied.
SO ORDERED.
