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
fl
exible
or rigid, may be attached to the inlet at the stove’s rear (refer to
fi
gure 4).
A rodent guard (minimum ¼” wire mesh)/wind hood must be used at the
terminus (refer to
fi
gure 5). All connections must be secured and airtight by
either using the appropriately sized hose clamp and/or UL-181-AP foil tape.
For mobile home installations only:
2” inside diameter pipe may be used
for the
fi
rst 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. In
fi
replaces
• Chimney
top.
•
Ash clean out door.
b. For freestanding installations
•
A hole in
fl
oor near stove rear terminating only in a ventilated
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 easily
available to the air inlet. A closeable outside air register can be used in
tightly insulated homes. In insert installations,
fl
ashing vents should not be
restricted. The
fl
ashing should not necessarily seal the
fi
replace face.
VENTING
Your appliance is certi
fi
ed for use with listed TYPE L-Vent, 3” or 4” diam-
eter 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. We suggest sealing all vent connec-
tor joints with 500°F (260°C) RTV silicone sealant to ensure consistent per-
formance and to avoid smoke spillage. We also suggest that all horizontal
connector joints be sealed with UL-181-AP foil tape.
It is strongly recommended that you have a minimum of 6’ of vertical pipe in
your exhaust system. For best performance of the stove limit the number
of elbows and horizontal pipe as much as possible
FOLLOW L-VENT CHIMNEY MANUFACTURER’S INSTALLATION IN-
STRUCTIONS.
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING AN-
OTHER APPLIANCE.
DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING SYS-
TEM OF THIS UNIT.
INSTALL VENT AT CLEARANCES SPECIFIED BY THE VENT MANU-
FACTURER.
IMPORTANCE OF PROPER DRAFT
Draft is the force which moves air from the appliance up through the
chimney. The amount of draft in your chimney depends on the length of the
chimney, local geography, nearby obstructions and other factors. Too much
draft may cause excessive temperatures in the appliance. Inadequate draft
may cause backpuf
fi
ng into the room and ‘plugging’ of the chimney.
Inadequate draft will cause the appliance to leak smoke into the room
through appliance and chimney connector joints.
An uncontrollable burn or excessive temperature indicates excessive draft.
Take into account the chimney’s location to insure it is not too close to
neighbors or in a valley which may cause unhealthy or nuisance conditions.
