Osburn Stoves by SB I HYBRID-45 MF - Manual (Page 6)

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 Vent type UL-103
or ULC S629M and Chimney type UL-641 or ULC S609, 3” or 4”
diameter in size. This unit can be installed in an existing chimney
with the addition of a liner if it’s 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.
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.
