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 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 P23 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.

DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.

DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING SYSTEM OF THIS UNIT.
