Osburn Stoves by SB I HYBRID-45 MF Benutzerhandbuch

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. 

• 

A hole in floor near stove rear terminating only in a 
ventilated crawl space. 

• 

A hole in the wall behind the stove. 

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. 

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.
