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 ¼” 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
: No combustion air supply
may exceed 10 feet.
Sources of Outside Combustion Air
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 be easily
available to the air inlet. A closeable outside air register can be used
in tightly insulated homes.
VENTING
The Osburn Hybrid-45 MF is certified for use with a vent certified to
UL-103 or ULC S629M and a chimney type vent certified to UL-641
or ULC-S-609-M89 and ULC/ORD C441-M90, with 3” or 4” inner
diameter. In Canada, we recommend that you use
a listed pellet
vent that meets the ULC S-609-M89 and ULC/ORD C441-M90
Standards. For the United States, we recommend that you use a
listed pellet vent that meets the UL-641, 7
th
edition Standard.
This
unit can be vented in an existing chimney with the addition of a liner
if the chimney is more than 4” in diameter. Class “A” chimney is not
required. Refer to the instructions provided by the vent or chimney
manufacturer, especially when passing through a wall, ceiling, or
roof.
Your venting system should have at least one foot of vertical
rise for each foot of horizontal run. The total vertical rise
should never be less than 3 feet (see Appendix A).
This is a pressurized exhaust system. All vent connector joints must
be sealed and fastened in accordance with the pellet pipe
manufacturer's instructions to ensure consistent performance and
avoid smoke and ash spillage.
