Breckwell P22FSL - 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 5a, 5b, 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 P22 Freestanding 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
° F (260 ° 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
recommend that all vertical vent connector joints be secured with a
minimum of 3 screws.
