Attaching the exhaust and air inlet connection adaptors to the top of
the heater
▶ Attach the flue gas exhaust accessory to the top of the unit fig. 20
(position 1) using the 4 screws and gasket provided, and fully insert
vent pipe into the accessory.
▶ If using 4" venting, a 3" to 4" increaser should be installed directly
after this accessory.

NOTE: Vent pipe must be completely vertical when
inserting or blue gasket inside exhaust accessory can
become displaced. Exhaust accessory can be removed
with vent pipe attached to check gasket position.
NOTE: The combustion air accessory can be installed on
the top right or on the top left side of the heater. The
combustion air inlet that is not used must be kept sealed.
