Breckwell P23I - Manual (Page 6)

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 figures
5 and 6). A rodent guard (minimum ¼” wire mesh)/wind
hood must be used at the terminus (refer to figure 7). 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 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. In
fireplaces
• Chimney top.
• Ash clean out door.
b. For freestanding installations
•
A hole in floor 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, flashing vents should not be restricted.
The flashing should not necessarily seal the fireplace
face.
VENTING
The Breckwell P4000 Vermont 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. We suggest
sealing all vent connector joints with 500
°F (260°C) RTV
silicone sealant to ensure consistent performance and to
avoid smoke spillage. We also suggest that all horizontal
connector joints be sealed with UL-181-AP foil tape.
