WARNING
PLANNING THE INSTALLATION
In planning the installation for the replace it is necessary
to determine where the unit is to be installed and whether
optional accessories are desired. Gas supply piping should
also be planned. The following steps represent the normal
sequence of installation. Each installation is unique, however, and might require a different sequence.
1. Position replace in desired location. Refer to the Fire-
place Location (page 8, Figure 3) and Clearances and
Height Requirements (page 9, Figures 4 and 5) sections
and Fireplace and Framing Dimensions (page 6, Figure
2) illustration found in this manual.
NOTE: Be sure all packing material has been removed
from under the unit.
2. Install following the instructions found in this manual.
3. Field wire main power supply to junction box. Refer to
the Electrical Installation section (page 13). (Electrical
connections should only be performed by an experi-
enced, licensed certied service person).
4. Plumb gas line. Refer to the Connect the Gas (page
11, Figure 7) section found in this manual. (Gas
connections should only be performed by an experi-
enced, licensed/certied service person).
5. Complete nish wall material and/or surround.
ADEQUATE COMBUSTION AND VENTILATION AIR
This heater shall not be installed in a conned space or
unusually tight construction unless provisions are provided
for adequate combustion and ventilation air.
The National Fuel Gas Code, (ANSI Z223.1/NFPA54),
denes a conned space as a space whose volume is less
than 50 cubic feet per 1,000 BTU per hour (4.8m3 per kw) of
the aggregate input rating of all appliances installed in that
pace, and an unconned space as a space whose volume
is not less than 50 cubic feet per 1,000 BTU per hour (4.8
m3 per kw) of the aggregate input rating of all appliances
installed in that space. Rooms communicating directly with
the space in which the appliances are installed, through
openings not furnished with doors, are considered a part
of a conned space.
Unusually tight construction is dened as construction
where:
a. Walls and ceilings exposed to the outside atmosphere
have a continuous water vapor retarder with a rating of
1 perm (6 x 1011 kg per pa/sec-m2) or less with openings
gasketed or sealed, and
b. Weather stripping has been added on openable win-
dows and doors, and

c. Caulking or sealants are applied to areas such as joints
around window and door frames, between sole plates
and oors, between wall-ceiling joints, between wall
panels, at penetrations for plumbing, electrical and gas
lines and other openings.
The following formula can be used to determine the maxi-
mum heater rating per the denition of unconned space:
BTU/Hr = (L1 + L2) Ft x (W) Ft x (H) Ft
50
Consider two connecting rooms with an open area
between, with the following dimensions:
L1 = 151/2 Ft., L2 = 12 Ft., W = 12 Ft., H = 8 Ft.
BTU/Hr = (151/2 + 12) x (12) x (8)
50
If there were a door between the two rooms the calculation
would be based only on the room with the heater.
BTU/Hr = (151/2) x (12) x (8)
