INSTALLATION
COMBUSTION AIR SUPPLY
For a mobile home installation the stove must be connected to an
outside source of combustion air. A 2” inside diameter metallic pipe,
either flexible or rigid, may be attached to the inlet at the stove’s
rear (refer to figure 5a.) A rodent guard (minimum ¼” wire mesh)/
wind hood must be used at the terminus (refer to figure 7). All con-
nections must be secured and airtight by either using the appropri-
ately sized hose clamp and/or UL-181-AP foil tape.
For mobile home installations only: 2” inside diameter pipe may
be used for the first 5 feet of combustion air supply run. From 5 to
10 feet use 2 ¾” inside diameter pipe. No combustion air supply
may exceed 10 feet.
Sources of Outside Combustion Air
a. For freestanding installations
• A hole in floor near stove rear terminating only in a venti
lated crawl space.
• A hole in the wall behind the stove.
WHEN OUTSIDE AIR IS NOT USED
If outside air is not used, it is important that combustion air is eas-
ily available to the air inlet. A closeable outside air register can
be used in tightly insulated homes. In insert installations, flashing
vents should not be restricted. The flashing should not necessarily
seal the fireplace face.
VENTING
This freestanding appliance is certified for use with listed TYPE L-
Vent, 3” or 4” diameter in size. The stove was tested with Simpson
Duravent brand. Class “A” chimney is not required. Refer to the
instructions provided by the vent manufacturer, especially when
passing through a wall, ceiling or roof.
This is a pressurized exhaust system. All vent connector joints
must be sealed with 500 O F (260 O C) RTV silicone sealant to ensure
consistent performance and avoid smoke spillage. All horizontal
connector joints must be sealed with UL-181-AP foil tape. We rec-
ommend that all vertical vent connector joints be secured with a
minimum of 3 screws.
It is strongly recommended that you have a minimum of 6’ of ver-
tical pipe in your exhaust system. For best performance of the
stove limit the number of elbows and horizontal pipe as much as
possible.
