Harman Outside Air Assembly (Accentra 52i): 1-00-574350

All pellet-burning appliances require air for combustion. Without an outside air kit, the insert uses the already heated air within your home for combustion. The benefits of using an OAK for combustion air are: Better heating efficiency Air pressure is stabilized which is better for your health The seals on your windows and doors are not compromised by using the stove The sealed system alleviates smoke in your house during a power failure Kit Contents: 1- Air intake adapter 1- 3 inch pipe stub 1- Pipe stub gasket 4- 1/4-20 X 3/8 Flange head bolts 5- #10 Tek Screws - Compatible with the Harman Accentra 52i, Harman Accentra 52i TC
