Cottage Base Model: OMCCOT-BASE IMPORTANT: Adequate combustion air must be provided under all circumstances. If the underside of the home is skirted or enclosed e.g. by an enclosed crawlspace, the combustion air intake should exit through the side of cottage base and terminate outside of the structure. All joints and seams of supply ducts and combustion air ducts must be closed with a sealing method suitable to the application conditions and temperatures e.g. using high temperature silicone caulk and/or aluminum tape F. CLOSET INSTALLATION E. ALCOVE INSTALLATIONG. COMBUSTION AIR The preferred location of the outside combustion air intake termination e.g. an optional stainless steel intake hood, part no.370183 is through the side of the structure, skirting or enclosure. An alternate termination location is under the structure in the skirted or crawlspace area providing a minimum of 50 square inches of free area exists around the perimeter for outside combustion air to be drawn through. NOTE: Combustion air cannot be drawn from the occupied space of the home Figure H. FUEL PIPING 2.
