The Napoleon HMF150 may take outside combustion air directly into the appliance through a 4" inlet collar at
the back of the unit. This inlet is to supply combustion air for the HMF150 Wood Furnace only.
Secure and seal the intake liners to the collars using 3 sheet metal screws, and high temperature sealant.
Insulating the intake liners is recommended in colder climates to prevent condensation from occurring.
The 4" inlet can also draw combustion air from the room provided adequate make up air is available.

Code For Oil Burning Equipment", and installed by a certifi ed oil mechanic.
