• Check with the local building official for local code requirements (e.g., Are below grade penetrations of the gas
line allowed?, etc).
CAUTION
If propane is used, be aware that with a tank that is too small (i.e., under 100 lbs, if this is the only gas
appliance in the dwelling—see NPFA 58), there may be a loss of pressure. This can result in insufficient
fuel delivery that can cause sooting, delayed ignition, or other malfunctions. Any damage resulting from an
improper installation is not covered by the limited warranty.
4.
Rough in the Electrical Supply, if Needed
1.
As necessary, rough in the fireplace electrical supply per NEC and local codes.
5.
Place the Fireplace in the Framing and Secure
1.
Secure the fireplace to the side framing members using the unit’s nailing flanges —one top and bottom on each
side of the fireplace front. Use 8d nails or the equivalent.
NOTE:
Nailing flanges, combustible members, and screw heads in areas directly adjacent to the nailing flanges are
EXEMPT from the 1/2” clearance to combustible requirements for the firebox outer wrapper. Combustible framing
may be in direct contact with the nailing flanges and may be located within 1/2” of screw heads and the firebox
wrapper in areas adjacent to the nailing flanges.
VENT SYSTEM PREPARATION
6.
Select a Horizontal or Vertical Vent System
1.
With the fireplace secured in the framing, determine the vent route and identify the exterior termination location.
The following sections describe vertical (roof) and horizontal (exterior wall) vent applications. Use only approved
vent components (
Page 9
and
Page 46
).
NOTE:
This fireplace must be vented directly to the outside.
WARNING
The vent system may not service multiple appliances, and must never be connected to a
flue serving a separate solid fuel burning appliance.
NOTE:
The vent pipe is tested to be run inside an enclosed wall (such as a chase). There is no requirement for
inspection openings in the enclosing wall at any of the joints in the vent pipe.
7.
Install the Vent Restrictor (if necessary)
1.
Use the vent run descriptions in
Figure 14
to determine if a vent restrictor is necessary.
2.
If necessary, assemble the vent restrictor and wings as detailed in
Figure 14
and
Figure 16
.
3.
If necessary, install the appropriate vent restrictor with the flaps facing up (
Figure 15
). The vent restrictor is held in
place by friction. The vent restrictor must not be visible inside the firebox.
NOTE:
If the baffle and back panel are installed, remove them before installing the vent restrictor.
NOTE:
The vent restrictor is shipped in the firebox.
