K. Frequently Asked Questions
ISSUE SOLUTIONS
Condensation on the glass
Blue fl ames
Odor from appliance
This is a result of gas combustion and temperature variations. As the appliance warms, this condensation will disappear.
This is a result of normal operation and the fl ames will begin to yellow as the appliance is allowed
to burn for 20 to 40 minutes.
When fi rst operated, this appliance may release an odor for the fi rst several hours. This is caused
by the curing of materials from manufacturing. Odor may also be released from fi nishing materi-
als and adhesives used near the appliance. These circumstances may require additional curing
related to the installation environment.
Film on the glass
Metallic noise
Is it normal to see the pilot
fl ame burn continually?
This is a normal result of the curing process of the paint and logs. Glass should be cleaned within
3 to 4 hours of initial burning. A non-abrasive cleaner such as gas appliance glass cleaner may be
necessary. See your dealer.
Noise is caused by metal expanding and contracting as it heats up and cools down, similar to the
sound produced by a furnace or heating duct. This noise does not affect the operation or longevity
of the appliance.
In an Intellifi re ignition system it is normal to see the pilot fl ame, but it should turn off when ON/
OFF is turned to OFF. In a standing pilot system the pilot will always stay on.

Framing and Clearances
A. Selecting Appliance Location
When selecting a location for the appliance it is important
to consider the required clearances to walls (see Figure
5.1).
WARNING! Risk of Fire or Burns! Provide adequate
clearance around air openings and for service access. Due
to high temperatures, the appliance should be located out

B. Constructing the Appliance Chase
A chase is a vertical box-like structure built to enclose the
gas appliance and/or its vent system. In cooler climates
the vent should enclosed inside the chase.
NOTICE:
fi restops and construction of the chase may vary with the
type of building. These instructions are not substitutes for the
requirements of local building codes. Therefore, you MUST
check local building codes to determine the requirements
to these steps.
Chases should be constructed in the manner of all outside walls of the home to prevent cold air drafting problems. The chase should not break the outside building
envelope in any manner.
Walls, ceiling, base plate and cantilever fl oor of the chase
should be insulated. Vapor and air infi ltration barriers
should be installed in the chase as per regional codes for
the rest of the home. Additionally, in regions where cold
air infi ltration may be an issue, the inside surfaces may
be sheetrocked and taped for maximum air tightness.
Treatment of ceiling fi restops and wall shield
1/2 in. (13 mm)
To further prevent drafts, the wall shield and ceiling fi re-
stops should be caulked with high temperature caulk to
seal gaps. Gas line holes and other openings should be
caulked with high temp caulk or stuffed with unfaced insulation. If the appliance is being installed on a cement slab,
a layer of plywood may be placed underneath to prevent
conducting cold up into the room.
C. Clearances
NOTICE: Install appliance on hard metal or wood surfaces
extending full width and depth. DO NOT install directly on
carpeting, vinyl, tile or any combustible material other than
wood.
WARNING! Risk of Fire! Maintain specifi ed air space
clearances to appliance and vent pipe:
• Insulation and other materials must be secured to
prevent accidental contact.
• Failure to maintain airspace may cause overheating and
a fi re.
Combustible flooring may be installed next
to the front of the appliance.

may be installed horizontally. See Figure 7.9.
• Elbows may be placed back to back anywhere in the
system as long as the fi rst 90° elbow is a starter elbow
except as shown in Figure 7.4.
• When penetrating a combustible wall, a wall shield
fi restop must be installed.
• When penetrating a combustible ceiling, a ceiling
fi restop must be installed.
• Horizontal runs of vent do not require vertical rise;
horizontal runs may be level.
Note: The CNXT series appliances can adapt to
SLP series vent pipe when venting off the top of
the appliance. You must use a DVP-SLP24 adapter
which can only be attached to the appliance starting
collar.
When looking at horizontal termination diagrams, the
adapter is not counted as part of the minimum vertical
(V
min.) requirements.

Vent Clearances and Framing
A. Pipe Clearances to Combustibles
WARNING! Risk of Fire! Maintain air space clearance to
vent. DO NOT pack insulation or other combustibles:
• Between ceiling fi restops
• Between wall shield fi restops
• Around vent system
Failure to keep insulation or other material away from
vent pipe may cause over heating and fi re.
Note: Heat shields MUST overlap by a minimum of 1-1/2 in. (38 mm).
• DVP heat shield - designed to be used on a wall 4 in. to 7-1/4 in. (102 mm to 184
mm) thick.
• If wall thickness is less than 4 in. the existing heat shields must be field trimmed.
If wall thickness is greater than 7-1/4 in. an extended heat shield will be required.
• SLP heat shield - designed to be used on a wall 4-3/8 in. to 7-5/8 in. (111 mm to 194
mm thick).
• If wall thickness is less than 4-3/8 the existing heat shields must be field trimmed.
If wall thickness is greater than 7-5/8 in. an extended heat shield will be required.

B. Wall Penetration Framing
Combustible Wall Penetration
Whenever a combustible wall is penetrated, you must
frame a hole for the wall shield fi restop(s). The wall shield
fi restop maintains minimum clearances and prevents cold
air infi ltration.
• The opening must be framed on all four sides using the
same size framing materials as those used in the wall
construction.
• SLP pipe - A wall shield fi restop must be placed on each
side of an interior wall. A minimum 1 1/2 in. (38 mm)
overlap of attached heat shields must be maintained.
• DVP pipe - A wall shield fi restop is required on one side
only on interior walls. If your local inspector requires a
wall shield fi restop on both sides, then both wall shield
fi restops must have a heat shield attached to them.
• See Section 10.N. for information for regarding the
installation of a horizontal termination cap.
Non-Combustible Wall Penetration
If the hole being penetrated is surrounded by noncombustible materials such as concrete, a hole with diameter one
in. greater than the pipe is acceptable.
Whenever a non-combustible wall is penetrated, the wall
shield fi restop is only required on one side and no heat
shield is necessary.

C. Install the Ceiling Firestop
A ceiling fi restop MUST be used between
fl oors and attics.
• DVP pipe only - Frame an opening 10 in.
by 10 in. (254 mm by 254 mm) whenever
the vent penetrates a ceiling/fl oor (see
Figure 8.3).
• SLP pipe only - Frame opening 9 in. x
9 in. (229 mm x 229 mm) whenever the
vent penetrates a ceiling/floor (see Figure
8.3).
• Frame the area with the same sized lumber
as used in ceiling/fl oor joist.
• The ceiling fi restop may be installed above
or below the ceiling joists when installed
with a attic insulation shield. It must be
under joists between fl oors that are not
insulated. Refer to Figure 8.4.
• Secure with three fasteners on each side.
WARNING! Risk of Fire! DO NOT pack insulation around the vent. Insulation must be
kept back from the pipe to prevent overheating.

requires the use of an attic shield.
The National Fuel Gas Code ANSI Z223.1 and NFPA 54
requires an attic shield constructed of 26 gauge minimum
metal that extends at least 2 in. (51 mm) above insulation.
Attic shields must meet specifi ed clearance and be se-
cured in place.
Flat Ceiling Installation
• Remove one shield from box.
NOTICE: Cut previously installed batt insulation to make
room for the attic insulation shield.
• Wrap shield around pipe if pipe is already installed in
area to be insulated.
• Match the three holes in each side and fasten with three
screws to form a tube.
• Bend three tabs on the bottom of the shield outward to
allow attachment to the ceiling fi restop.
• Bend the remaining bottom tabs inward 90° to maintain
the air space between the pipe and the shield. Set the
shield on the ceiling fi restop and attach to the fi restop.
• Bend all tabs inward 90° around the top of the shield.
These tabs must be used to prevent blown insulation
from getting between the shield and vent pipe, and to
maintain air space clearance.
Bend all tabs inward
90° to maintain
clearance and
prevent insulation
from falling inside

Installing Vent Pipe
A. Assemble Pipe Sections (DVP Only)
Attach Pipe to the Firebox Assembly
Note: The end of the pipe sections with the lanced tabs will
face towards the appliance.
Attach the fi rst pipe section to the starting collar:
• Lanced pipe end to the starting collar
• Inner pipe over inner collar
• Push the pipe section until all lanced tabs snap in
place
• Lightly tug on pipe to confi rm it has locked.
Commercial, Multi-family (Multi-level exceeding
two stories), or High-Rise Applications
All outer pipe joints must be sealed with high temperature
silicone, including the slip section that connects directly to
the horizontal termination cap.
• Apply a bead of silicone sealant inside the female outer
pipe joint prior to joining sections. See Figure 10.1
• Only outer pipes need to be sealed. All unit collar, pipe,
slip section, elbow and cap outer fl ues shall be sealed in
this manner, unless otherwise stated.

Lances
WARNING! Risk of Fire or Explosion! DO NOT break
silicone seals on slip sections. Use care when removing
termination cap from slip pipe. If slip section seals are broken during removal of the termination cap, vent may leak.
Assemble Pipe Sections (DVP Only)
Per Figure 10.2:
• Start the inner pipe on the lanced end of section A into
the fl ared end of section B.
• Start the outer pipe of section A over the outer pipe of
section B.
• Once both vents sections are started, push fi rmly until
all lanced tabs lock into place.
• Lightly tug on the pipe to confirm the tabs have
locked.
It is acceptable to use screws no longer than 1/2 in. (13
mm) to hold outer pipe sections together. If predrilling
holes, DO NOT penetrate inner pipe.
For 90° and 45° elbows that are changing the vent
direction from horizontal to vertical, one screw minimum
should be put in the outer fl ue at the horizontal elbow joint
to prevent the elbow from rotating. Use screws no longer
than 1/2 in. (13 mm). If predrilling screw holes, DO NOT
penetrate inner pipe.

E. WSK-MLT Multifunction Wall Switch
The WSK-MLT multifunctional wall switch is designed to
control fl ame height, blower speed and auxilary func-
tions on your gas fi replace. For models equipped with
the Intellifi re system (IPI), the cold climate function can
control the pilot fl ame as well. The wall switch is equipped
with thermostat functions which can automatically control the temperature in the room in which it is installed.
An auxiliary function provides 110-120 VAC source for
added features the fi replace may have installed. Electri-
cal ratings for the control box are 110 VAC, 60 Hz, and is
required for operation of this device.
Precautions
This remote is tested and safe when installed in accordancewith this installation manual. It is your responsibility
to read all instructions before starting installation and to
follow these instructions carefully during installation. Do
not install any components that may be damaged. Do not
modify, disassemble, or substitute any of the components
included with this kit. Installation of this unit must be done

I. WSK-MLT Operating Instructions
The ON/OFF rocker switch in the fi replace (located near
the gas valve) must be in the “OFF” position for use with
the WSK-MLT system. The ON/OFF rocker switch will
NOT function with this device on Intellifi re (IPI) mod-
els except during a power outage. The ON/OFF rocker
switch will only be used to control the fi replace in a no-
power condition.
After all connections are made and the control box is
grounded, plug power cord into the fi replace junction box.
The wall switch will be functional at this time.
For IPI system, refer to “Operation Under Battery Power”
for instructions.
Note: The temperature displayed by the wall switch may
take up to 30 minutes to stablize on initial power-up.
Note: Check control box and assure switch is in the “OFF”
position. This switch is only used on Intellifi re (IPI) control
systems under battery operation.
J. Setting Flame Height/Manifold Pressure
(To be done by a qualifi ed service technician.) Upon initial
power-up of this device, valve pressure must be set for
fl ame adjustment.
• Loosen output pressure tap on valve and connect with
pressure manometer.
• Press fl ame button once (see Figure 12.8); fi replace will
light with fl ames on high.
• Turn solenoid clockwise to increase pressure,
counterclockwise to decrease pressure until manifold
pressure on high is 3.5 in. water column for natural gas
(NG), 10.0 in. water column for propane (LP).
• Once pressure is achieved sping jam nut on solenoid
step tight against regulator face to prevent rotation. Do
not overtighten.
• Press fl ame button twice to turn fi replace off.
• Remove manometer tube and tighten or close pressure
tap. Use a commercially available, non-corrosive leak
check solution to carefully check the pressure tap for
leaks. Be sure to rinse off all leak check solution following
testing.

Operation Under Battery Power
A switch on the control box allows for battery power
under no-power conditions (see Figure 12.9). By controlling the power supply with this switch, the batteries are
supplying power only when needed, thus extending battery life. The switch also provides a convenient means for
switching to battery power should there be a loss of 110
VAC power to the control box.
• In the event of a power failure, switch the battery
operation switch to the “Battery ON” position.
• The fi replace can now be turned on and off with the
ON/OFF rocker switch located near the gas valve.
• The wall switch functions will not operate under battery
power.
• Under battery control the only available function is fl ame
“ON” and “OFF” in the high position.
• To maximize battery life, and to restore full function
capability of the wall switch, fl ip switch to “OFF” position
after 120 VAC power is restored.
