All installations and services must be performed by qualified service personnel.
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).
If the combustion air passageway cannot terminate outside of the structure, a permanent
opening with a minimum of 50 square inches of unobstructed infiltration (free area) for
ventilation and combustion air must be provided to the interior of the structure. Additional
make-up air may need to be supplied to the interior of the structure to compensate for exhaust
fans, appliances, or vents which consume air from the interior of the structure.
Refer to the assembly installation instructions included with 01COT-BASE cottage base for
additional information.
