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 orother soft floorcoverings. It
may, however, be placed on flat wood, ply-
wood, 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.

NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE.
The fireplace should be secured to the side framing
membersusingtheunit'snailingflanges-twoatthe
top and bottom on each side of the fireplace front.
See
Figure 11. Use 8d nails or their equivalent.
All appliances are equipped with a gas flex line
and shutoff valve attached directly to the gas
control valve. Use of the gas flex line will aid in
the routing and attachment of the gas line to
the fireplace.
Step 3. Position the Appliance - Slide the
fireplace into prepared framing or position fire-
place in its final position and frame later.
Refer to fireplace drawings and specifications
on
page 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 (REFER
TO FIGURE 4 ) 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 DI-
RECT CONTACT WITH THE TOP SPACERS BUT
MAY NOT BE SUPPORTED BY THEM.
WARNING: CONNECTING DIRECTLY TO
AN UNREGULATED PROPANE (L.P.G.)
TANK MAY CAUSE AN EXPLOSION.
Fireplace may be anchored to floor. Bend down
twoanchortabs(oneoneachside)locatedatthe
base of the fireplace and secure to the floor by
nailing with 8d nails or equivalent (Figure 12 ).
Figure 12
Figure 11
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 addi-
tional 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 6 through 9 on page 6 .
Note: The framed depth, 16 in. (406 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 16 in. (406 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.
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
(see Figure 10 ) using tech-
niquesandmaterialsprescribed bylocaland/or
national codes. It is recommended that a gas
line of ¹⁄₂" or greater diameter be used to allow
fullgasvolumetothefireplace.Unduepressure
loss will occur if the pipe is too small. The
appliance,as setup atthe 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 in-
stalled 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 con-
trols and burners. Failure to do so could prevent
the appliance from operating reliably.
An external regulator must be used on all pro-
pane (L.P.G.) heaters to reduce the supply tank
pressure to 13" w.c. (maximum). Any copper
tubingusedtosupplypropane(L.P.G.)fromthe
tank must be internally tinned.
IMPORTANT: HOLD GAS VALVE SECURELY
TO PREVENT MOVEMENT WHEN CONNECT-
ING TO INLET GAS LINE
Note:
Some units only have one anchor tab on each side.

(See Figure 15) –
1. Select any of the following optional con-
trols: appliance-mounted (rocker switch) or
wall-mounted switch, thermostat, or one of
the optional remote control kits. If appliance-
mounted ON/OFF control is selected mount it
in the gas valve mounting bracket.
2. If wall-mounted ON/OFF control switch or
thermostatis selected mountit ina convenient
location on a wall near the fireplace.
3. Wire the control switch within the millivolt
control circuit using the 15 feet of 2 conductor
wire supplied with the unit . Caution: do not
connect the optional wall switch to a 120V
power supply.
4. Alternatively, the appliance may be oper-
ated without the use of the controls indicated
in step 1, solely by manipulating the gas valve
control knob. In order to use this method,
twist the free ends of the two conductor wire
(located in the lower compartment of the unit)
together as shown in

B. Electronic Wiring (See figure 17 or 18) –
Note: The electronic appliance must be con-
nected to the main power supply.
Ajunctionboxislocated attherearofthecontrol
compartment on either side of the cabinet. The
junction box on the right side contains a factory
installed and wired outlet box (duplex recep-
tacle). Also, an optional field-provided junction
box with receptacle may be installed at the front
of the control compartment on either side of the
cabinet.
See Figure 16. It will be held in place by
a conduit fitting and locknut (field-provided).
1. Route a 3-wire 120Vac 60Hz 1ph power
supply to the appliance junction box.
2. If the factory-provided outlet/junction box
at the right rear of the fireplace is being used,
removethe outletbox fromthe junction boxby
removing two screws.
3. Connect the power supply wires (including
the ground supply wire) as shown in
Figures

(If the field-provided J-box/outlet
box is being used, all of the outlet box wiring
must be field-provided.)
4. Locate and install a low voltage (24V) wall-
mounted switch or thermostat (both field-
provided) in the desired location.
5. Connect the low voltage wire, located in the
lower control compartment, to the wall-
mounted switch or thermostat.
Note:Thesupplied15feetof2conductorwirehas
one end of each conductor connected to the gas
valve circuit and the other end of each conductor
placed inside the control compartment.
6. Insert the control circuit plug into the
unswitched receptacle of the outlet box.
7. After wiring is complete, mount the outlet
box to the J-Box.

Secure all joints tightly using appropri-
ate tools and sealing compounds (en-
sure propane resistant compounds are
used in propane applications).
Make gas line connections. All codes require a
shut-off valve mounted in the supply line.
Figure 19 illustrates two methods for con-
necting the gas supply. The flex-line method is
acceptable in the U.S., however, Canadian re-
quirementsvarydependingonlocality.Installa-
tion must be in compliance with local codes.
These appliances are equipped with a gas flex
linefor use (where permitted) inconnecting the
unit to the gas line. A gas flex line is provided to
aid in attaching the direct vent appliance to the
gas supply. The gas flex line can only be used
where local codes permit. See

Step 8. Outside Air Kits –Optional outside
make-up air kits, Model FOAK-4 or FAOK-4LD,
may be used with these appliances. Refer to
the installation instructions packaged with the
air kits for specific installation information. If
used, 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 out-
side air duct is necessary, if installed. See
Figure 4 on page 5 for the location of the
unit's outside air inlet.
If additional length of duct is necessary, pur-
chase locally available U.L. Class 0 or Class 1
metallic ducting. The duct may extend up to
50' (15.24 m) in any direction.
Note: When installing the air duct vertically,
DO NOT terminate the duct closer than 3'
below the chimney top.
Outside combustion air ducting may be run
upwards or vertically through framing and
ceiling joists, with the hood installed through
an outside wall and 3' (1 m) below the termi-
nation. Ducting may also be run downward
through floor joists and under the home to a
ventilated crawlspace not considered part of
the living area of the home.
Note: Do not terminate outside air kit in attic
space under any circumstances.
CAUTION: NEVER LOCATE INLET WHERE IT
CAN BE BLOCKED BY SHRUBS, SNOW
DRIFTS, ETC. NEVER LOCATE INLET IN GA-
RAGE OR ANY AREA WHERE THERE IS AN-
OTHERFUELBURNINGAPPLIANCEORPROD-
UCTSEMITTINGCOMBUSTIBLEGASESSUCH
AS PAINT, GASOLINE, ETC. IN COLD CLI-
MATES, IT IS RECOMMENDED THE OUTSIDE
AIR DUCT BE INSULATED.
After completing the installation of the op-
tional outside air vent system the outside air
control lever must be put in service and tested
to ensure proper operation before completing
anyenclosurearoundthe firebox. Failuretodo
so may result in extensive and costly rework.
Before the operation of the vent system can be
tested, the lever securing screw must be re-
moved.
See Figure 21.
The hand operated outside air control lever is
located on the left side of the fireplace open-
ing. See Figure 21.
