TYPICAL INSTALLATION SEQUENCE
The typical sequence of installation follows,
however, each installation is unique resulting in
variations to those described.
1. Construct the appliance framing.
2. Route gas supply line to appliance location.
3. Install nailing flanges and position the appli-
ance.
4. Install the vent system and exterior termination.
5. Field wire and install operating control switch.
6. Make connection to gas supply.
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.
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.
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. Frame appliance enclosure as illus-
trated in
Note: The framed depth, 13
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 13
the drywall surface. It is important that this
dimension be exact.

.
7.
Install (optional) outside Air Kit.
8. Check log position.
9. Checkout appliance operation.
10. Adjust burner to ensure proper flame ap-
pearance.
NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
If the appliance is to be elevated above floor
level, a solid continuous platform must be
constructed.
The header may rest on the top metal spacers,
but must not be notched to fit around them.
Consult all local codes.
5
Step 2. 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
right side. The gas line may however be alternately routed from the left side.
When rigid pipe is used, an ANSI approved
manual shut-off valve and union must be installed upstream of the fireplace.
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. Slide the fireplace into prepared framing or position fireplace in its final position and
frame later.
IMPORTANT: UNDER NO CIRCUMSTANCES CAN
THE FIREPLACE TOP SPACERS (
FIGURE 2
) BE
REMOVED OR MODIFIED, NOR 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 provided nailing flanges. Use
8d nails

operation and freedom of movement. Return
the actuator arm to the locked position.
Step 8. Log Placement – This appliance is
equipped with two concrete logs wired and
shipped in place
(see Figure 19 )
. As located
at the factory the log set will require no adjustment before the appliance is placed in service.
Ensure logs are unbroken and located as shown.
To provide increased access to the lower control compartment, you may chose to remove
the front log. To do so, undo the twists in the
wires securing the log from below to each of the
grate tines. After removal of the log, cut the
wires off closely to log before reinstalling it.
These wires are only required for shipping. To
place the front log, position it, centered, on the
log rack in the cradel area provided.

When first lighting the appliance, it will take a
few minutes for the line to purge itself of air.
Once purging is complete, the pilot and burner
will light and operate as indicated in the instruction manual.
Subsequent lightings of the appliance will not
require such purging. Inspect the pilot flame
(remove logs, if necessary, handling carefully).
MANUALLY-RESET BLOCKED FLUE SAFETY
SWITCH
This appliance is equipped with a manuallyreset blocked flue safety switch. Refer to
Figure 21
for its location. If during appliance
operation, the flame goes out (independently
of the burner on/off wall switch), it may be due
to the operation of this safety limit switch.
First allow the appliance to cool. Then reset
the safety switch by pushing the red reset
button on the back of the switch.
To access the blocked flue safety switch, remove the limit switch bracket, with switch and
low voltage wires attached. Push the red reset
button and then reinstall limit switch bracket.
The appliance should then relight and remain
lit. If this does not occur, turn off the appli-
ance and call a qualified service technician.

Proper Flame
Adjustment
.
Figure 23
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.
3/8 To 1/2 Inch
Ground
Electrode
Flame Rod
Hot Surface
Igniter
No smoke or soot should be present. 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
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.
