The typical sequence of installation follows,
however, each installation is unique resulting
in variations to those described.
1. Construct the appliance framing.
F
2. Route gas supply line to appliance location.
3. Position the appliance.
4. Install the vent system and exterior termina-
tion.
5. Field wire and install operating control switch.
6. Make connection to gas supply.
7. Install (optional) outside Air Kit.
8. Install the logs and rockwool.
9. Checkout appliance operation.
10. Adjust burner to ensure proper flame ap-
pearance.
PRE-INSTALLATION NOTES
The fireplace may be installed directly on a
combustible floor or raised on a platform of an
appropriate height. Do not place fireplace on
carpeting, vinyl or other soft floor coverings. It
may, however, be placed on flat wood, plywood, particle board or other hard surfaces. Be
sure fireplace rests on a solid continuous floor
or platform with appropriate framing for support and so that no cold air can enter the room
from under the fireplace.
The fireplace may be positioned and then the
framing built around it, or the framing may be
constructed and the fireplace positioned into
the opening.
Usually, no special floor support is needed for
the fireplace, however, to be certain:
1. Estimate the total weight of the fireplace
system and surround materials such as brick,
stone, etc., to be installed.
2. Measure the square footage of the floor
space to be occupied by the system, surrounds
and hearth extensions.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
3. Note the floor construction, i.e. 2 x 6’s, 2 x
8’s or 2 x 10’s, single or double joists, type and
thickness of floor boards.
5
4. Use this information and consult your local
building code to determine if you need additional support.
If you plan to raise the fireplace and hearth
extension, build the platform assembly then
position fireplace and hearth extension on top.
Secure the platform to the floor to prevent
possible shifting.
INSTALLING THE FIREPLACE
Step 1. Construct the Appliance Framing -
Frame appliance enclosure as illustrated in
Figures 4 through 7
Note: The framed depth, 20-1/2" (521 mm)
from a framed wall, must always be measured
from a finished surface. If a wall covering such
as drywall is to be attached to the rear wall, then
the 20-1/2" (521 mm) must be measured from
the drywall surface. It is important that this
dimension be exact.
If the appliance is to be elevated above floor
level, a solid continuous platform must be
constructed.
on page 5.
Ensure that a sediment trap is installed in the
existing gas line, if not, install a sediment trap
upstream to prevent moisture and contaminants from passing through trap to the appliance controls and burners. Failure to do so
could prevent the appliance from operating
reliably.
An external regulator must be used on all
propane (L.P.G.) heaters to reduce the supply
tank pressure to 13" w.c. (maximum). Any
copper tubing used to supply propane (L.P.G.)
from the tank must be internally tinned.
IMPORTANT: HOLD GAS VALVE SECURELY
TO PREVENT MOVEMENT WHEN CONNECTING TO INLET GAS LINE
WARNING: CONNECTING DIRECTLY TO
AN UNREGULATED PROPANE (L.P.G.)
TANK MAY CAUSE AN EXPLOSION.
All appliances are equipped with a gas flex line
and shutoff valve attached directly to the gas
control valve. To quickly and easily complete
the gas line routing, use the gas flex line kit.
Step 3. Position the Appliance - Slide the
fireplace into prepared framing or position fireplace in its final position and frame later.
Refer to fireplace drawings and specifications
on pages 4 and 5 for framing dimensions and
details. Framing header may be positioned
directly on the fireplace top spacers.
IMPORTANT: UNDER NO CIRCUMSTANCES
CAN THE FIREPLACE TOP SPACERS
FIGURE 2 )
BE REMOVED OR MODIFIED, NOR
(refer to
MAY YOU NOTCH THE HEADER TO FIT
AROUND OR BE INSTALLED LOWER THAN
THE SPACERS. THE HEADER MAY BE IN DIRECT CONTACT WITH THE TOP SPACERS
BUT MAY NOT BE SUPPORTED BY THEM.
Fireplace should be secured to side framing
members using the full length 1/2 inch nailing
flanges that are integral to the appliance at each
side. Use 6d nails or equivalent
(Figure 9 )
.
The header may rest on the top metal spacers,
but must not be notched to fit around them.
Consult all local codes.
Step 2. Route Gas Supply Line - Route gas
line
(Figure 8 )
using techniques and materials prescribed by local and/or national codes.
It is recommended that a gas line of 1/2" or
greater diameter be used to allow full gas
volume to the fireplace. Undue pressure loss
will occur if the pipe is too small. The appliance, as set up at the factory, is best suited
for use with a gas line routed from the left
side. The gas line may however be alternately
routed from the right side.
This unit is provided with a gas line/switch
wire outlet at both sides (see
Figure 2
). The
gas line may be routed through this opening at
either the right or left side. Route the Millivolt
switch wire through the opening opposite form
the gas line. To avoid cutting the Millivolt
switch wire, do not route the switch wire
through the opening with the gas line.
When rigid pipe is used, an ANSI approved
manual shut-off valve and union must be installed upstream of the fireplace.

) and secure
with four sheetmetal screws (# 8 or larger).
Minimum overall height of the vent system
and appliance must be 12' (3.66 m) vertical
(no offset) or 17' (5.18 m) when an offset up
to 45 degrees from the vertical is used. The
lower part of the offset must not begin less
than 3' (0.914 m) above the top of the
fireplace
(see Figure 11 )
.
Maximum overall height of the vent system and
appliance should not exceed 40 feet (12.19m).

utilizing the gas flex line provided with the
appliance is acceptable in the U.S., however, Canadian requirements vary depending on locality. Installation must be in compliance with local codes.
The gas control valve is located in the lower
control compartment. To access the valve
remove the refractory access panel and set
aside
(Figure 14 ).
The control valve has a
3/8" (10 mm) NPT thread inlet port.
Secure all joints tightly using appropriate
tools and sealing compounds (ensure propane resistant compounds are used in propane applications).
Turn on gas supply and test for gas leaks,
using a gas leak test solution (also referred to
as bubble leak solution).

Note: Using a soapy water solution (50% dish
soap, 50% water) is an effective leak test
solution but it is not recommended, because
the soap residue that is left on the pipes/
fittings can result in corrosion over time. Never
use an open flame to check for leaks.
A. Light the appliance (refer to the lighting
instructions label in the control compartment
or in the Homeowner's Care and Operation
Instructions).
B. Brush all joints and connections with the
gas leak test solution to check for leaks. If
bubbles are formed, or gas odor is detected,
turn the gas control knob to the “OFF” position. Either tighten or refasten the leaking
connection and retest as described above.

Step 7. Optional Outside Air Kits – Combus-
tion (outside make-up air) kits, Model FOAK-4
or FAOK-4LD, may used with these appliances. Refer to the installation instructions
packaged with the air kits for specific installation information. The outside air kit must be
installed before the fireplace is framed and
enclosed in the finished wall.
Outside air drawn into the fireplace supplies
air to the fire for combustion. Only one combustion air duct on the right side of the fireplace is necessary if installed.
If additional length of duct is necessary, purchase locally available U.L. Class 0 or Class 1
metallic ducting. The duct may extend up to
50' (15.24 m) in any direction.
There is one hand operated air gate shut-off,
for utside make-up air, located at the right side
of the fireplace opening behind the screen. To

After completing the installation of the optional combustion air vent system the actuator
arm must be put in service and tested to
ensure proper operation before completing
any enclosure around the firebox. Failure to do
so may result in extensive and costly rework.
Operate the actuator through several cycles
including the closed position. Ensuring proper
operation and freedom of movement. Return
the actuator arm to the closed position.
Step 8. Installing Logs and Rockwool – The
logs are packaged within the firebox. Remove
the rockwool from the packaging and tear into
dime size pieces (see Homeowners Care and
Operation Instructions). Do not use more than
is necessary.
Displace Lava Rock to the center of the burner
pan when removing and reinstalling the burner

Step 10. Adjustments – The following para-
graphs address adjustment concerns and procedures.
Flame Appearance and Sooting
Proper flame appearance is a matter of taste.
Generally most people prefer the warm glow of
a yellow to orange flame. Appliances operated
with air shutter openings that are too large, or
with long vertical vent runs, will exhibit flames
that are blue and transparent. These weak, blue
and transparent flames are termed anemic.
If the air shutter opening is too small sooting
may develop. Sooting is indicated by black
puffs developing at the tips of very long orange
flames. Sooting results in black deposits forming on the logs, appliance inside surfaces and
on exterior surfaces adjacent to the vent termination. Sooting is caused by incomplete combustion in the flames and a lack of combustion
air entering the air shutter opening.
To achieve a warm yellow to orange flame with
an orange body that does not soot, the shutter
opening must be adjusted between these two
extremes.
No smoke or soot should be present. Reposition the log set if the flames impinge on any of
them.
If sooting conditions exist, the air shutter
opening on the main burner can be adjusted.
Normally, the more offsets in the vent system,
the greater the need for the air shutter to be
opened further.
WARNING: AIR SHUTTER ADJUSTMENT
SHOULD ONLY BE PERFORMED BY A
QUALIFIED PROFESSIONAL SERVICE
TECHNICIAN.
Adjustment
To adjust the flame, position the air shutter to
the nominal setting
(Figure 22 ).
Allow the
burner to operate for at least 30 minutes.
Observe the flame continuously. If it appears
weak or sooty as previously described, adjust
the air shutter open or closed until desired
effect is achieved.
Note: If the flame still appears anemic with the
air shutter closed all the way (usually a result of
lengthy vertical venting runs), turn off the appliance, turn off the gas supply, wait for the parts
to cool and access the air shutter. The shutter
is prevented from actually closing by a tab that
is bent over into the opening. Remove this
obstruction by bending back. Reassemble and
restart the appliance and after 24 minutes
reobserve the flame. Adjust the air shutter as
described.
