COMBUSTION AIR SUPPLY
For a mobile home installation the stove must be connected to an outside
source of combustion air. A 3” inside diameter metallic pipe, either flexible
or rigid, may be attached to the inlet at the stove’s rear (refer to figures 4, 5
& 6). A rodent guard (minimum 1/4” wire mesh) must be used at the
terminus (refer to figure 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
: combustion air supply conduit may
not exceed 10 feet.
Sources of Outside Combustion Air
•
A hole in the wall behind the stove.(Figure 5)
•
A hole in floor near stove rear terminating only in a ventilated
crawl space.(Figure 6)
WHEN OUTSIDE AIR IS NOT USED
If outside air is not used, it is important that combustion air be easily
available to the air inlet. A closable outside air register can be used in
tightly insulated homes.
