K. Frequently Asked Questions
ꢀ
ISSUE
SOLUTIONS
This is a result of gas combustion and temperature variations. As the appliance warms, this con-
densation will disappear.
Condensation on the glass
This is a result of normal operation and the flames will begin to yellow as the appliance is allowed
to burn for 20 to 40 minutes.
Blue flames
When first operated, this appliance may release an odor for the first several hours. This is caused
by the curing of materials from manufacturing. Odor may also be released from finishing materi-
als and adhesives used near the appliance. These circumstances may require additional curing
related to the installation environment.
Odor from appliance
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.
Film on the glass
Metallic noise
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.
Is it normal to see the pilot
In an Intellifire ignition system it is normal to see the pilot flame, but it should turn off when ON/
flame burn continually?
OFF is turned to OFF. In a standing pilot system the pilot will always stay on.

To further prevent drafts, the wall shield and ceiling fire-
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 insu-
lation. 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.
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: Treatment of ceiling firestops and wall shield
firestops 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.
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.
Chases should be constructed in the manner of all out-
side walls of the home to prevent cold air drafting prob-
lems. The chase should not break the outside building
envelope in any manner.
WARNING! Risk of Fire! Maintain specified air space
clearances to appliance and vent pipe:
Walls, ceiling, base plate and cantilever floor of the chase
should be insulated. Vapor and air infiltration barriers
should be installed in the chase as per regional codes for
the rest of the home. Additionally, in regions where cold
air infiltration may be an issue, the inside surfaces may
be sheetrocked and taped for maximum air tightness.
•
•
Insulation and other materials must be secured to
prevent accidental contact.
Failure to maintain airspace may cause overheating and
a fire.

Vent Clearances and Framing
8
A. Pipe Clearances to Combustibles
WARNING! Risk of Fire! Maintain air space clearance to
vent. DO NOT pack insulation or other combustibles:
B. Wall Penetration Framing
Combustible Wall Penetration
Whenever a combustible wall is penetrated, you must
frame a hole for the wall shield firestop(s). The wall shield
firestop maintains minimum clearances and prevents cold
air infiltration.
•
•
•
Between ceiling firestops
Between wall shield firestops
Around vent system
Failure to keep insulation or other material away from
vent pipe may cause over heating and fire.
•
•
•
The opening must be framed on all four sides using the
same size framing materials as those used in the wall
construction.
SLP pipe -Awall shield firestop 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 firestop is required on one side
only on interior walls. If your local inspector requires a
wall shield firestop on both sides, then both wall shield
firestops must have a heat shield attached to them.
See Section 10.N. for information for regarding the
installation of a horizontal termination cap.
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.

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 first 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 confirm 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.
Figure 10.1 High Temperature Silicone Sealant
• Apply a bead of silicone sealant inside the female outer
pipe joint prior to joining sections. See Figure 10.1
A
• Only outer pipes need to be sealed. All unit collar, pipe,
slip section, elbow and cap outer flues 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 bro-
ken during removal of the termination cap, vent may leak.

Figure 10.2
Figure 10.3
Assemble Pipe Sections (DVP Only)
Per Figure 10.2:
Note: Make sure that the seams are not aligned to prevent
unintentional disconnection.
•
•
•
•
Start the inner pipe on the lanced end of section A into
the flared 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 firmly 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.
CORRECT
For 90° and 45° elbows that are changing the vent
direction from horizontal to vertical, one screw minimum
should be put in the outer flue 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.

Determine Location
E. WSK-MLT Multifunction Wall Switch
Determine the location for the wall switch. The chosen
location should provide an accessible location in the
same space as the gas fireplace. Never place this unit in
a separate room. The control wire supplied with this unit
is 17 ft (5.2 m) in length. The distance from the fireplace
to the switch may be lengthened provided that the wire
used never exceeds 50 ft, and that the distance from the
fireplace to the switch never exceeds 30 ft.
The WSK-MLT multifunctional wall switch is designed to
control flame height, blower speed and auxilary func-
tions on your gas fireplace. For models equipped with
the Intellifire system (IPI), the cold climate function can
control the pilot flame as well. The wall switch is equipped
with thermostat functions which can automatically con-
trol the temperature in the room in which it is installed.
An auxiliary function provides 110-120 VAC source for
added features the fireplace may have installed. Electri-
cal ratings for the control box are 110 VAC, 60 Hz, and is
required for operation of this device.
The switch should be mounted into a listed electrical junc-
tion box. The junction box should be dedicated to this wall
switch. Never install this wall switch into a junction box
that is shared with other electrical service or devices. If
possible, install this unit on an interior wall of the resi-
dence at a recommended height of 5 ft from the flooring.
Should the switch be installed on an exterior wall, be
certain wall insulation is kept intact and not damaged or
dislodged during the installation of the electrical junction
box.
Precautions
This remote is tested and safe when installed in accor-
dancewith 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
by a qualified service technician.
For exterior wall installations, it is recommended that the
junction box be sealed with caulking material. This will
minimize heat loss through this location and improve the
accuracy of the automatic (thermostat) operation.
Placement of this wall switch may affect performance or
accuracy of the automatic (thermostat) control. An as-
sessment of the space should be done prior to installation
for optimal performance. See “Determine Location” for
recommendations.
Note: The electrical junction box provided with the
fireplace must be wired with 110 VAC before installing
this kit.
All wiring should be done by a qualified electrician and
shall be in compliance with local codes and with the
National Electric Code ANSI/NFGA No. 70- current (in
the United States), or with the current CSA C22.1 CANA-
DIAN ELECTRIC CODE (in Canada).

I. WSK-MLT Operating Instructions
J. Setting Flame Height/Manifold Pressure
The ON/OFF rocker switch in the fireplace (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 Intellifire (IPI) mod-
els except during a power outage. The ON/OFF rocker
switch will only be used to control the fireplace in a no-
power condition.
(To be done by a qualified service technician.) Upon initial
power-up of this device, valve pressure must be set for
flame adjustment.
•
•
•
Loosen output pressure tap on valve and connect with
pressure manometer.
Press flame button once (see Figure 12.8); fireplace will
light with flames 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.
After all connections are made and the control box is
grounded, plug power cord into the fireplace 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.
•
•
Press flame button twice to turn fireplace 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.
Note: Check control box and assure switch is in the “OFF”
position. This switch is only used on Intellifire (IPI) control
systems under battery operation.

A switch on the control box allows for battery power
under no-power conditions (see Figure 12.9). By control-
ling the power supply with this switch, the batteries are
supplying power only when needed, thus extending bat-
tery 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.
Temperature Set Point can be adjusted between the rang-
es of 45-90° Fahrenheit or 7-32° Centigrade.
Note: The controller will turn off the fireplace at 2° F over
set point and turn it back on at 2° F below set point.

With fixed glass assembly in place, verify that flame is engulfing
flame sensing rod on left side of pilot hood. Flame sensing rod
should glow shortly after ignition. Verify correct pilot orifice is
installed and gas inlet is set to pressure specifications.
C. Module is not grounded.
Verify module is securely grounded to metal chassis of appliance.
Verify that wire harness is firmly connected to the module.
D. Damaged pilot assembly or
contaminated flame sensing
rod.
Verify that ceramic insulator around the flame sensing rod is not
cracked, damaged, or loose. Verify connection from flame sensing
rod to white sensor wire. Clean flame sensing rod with emery cloth
to remove any contaminants that may have accumulated on flame
sensing rod. Verify continuity with a multimeter with ohms set at
lowest range. Replace pilot if any damage is detected.
E. Module.
Turn ON/OFF rocker switch or wall switch to OFF position. Remove
ignitor wire “I” from module. Place ON/OFF rocker switch or wall
switch in ON position. If there is no spark at “I” terminal module
