Air for Combustion
• For proper and safe operation, the furnace needs air for
combustion and ventilation. Do Not block or obstruct
air openings on the furnace, or any air openings where
the furnace may be installed, including any surrounding
spaces.
• Direct vent furnaces pull combustion air from the
outdoors and vent combustion products back outside.
Combustion air coming from the outside needs to be
clean of chemicals that can cause corrosion, such as
pool chlorinating products.
Air for Comfort
• Keep air fi lters cleaned. It is recommended that the
furnace air fi lter be checked at least once a month. Clean
or replace fi lter to maintain proper airfl ow and achieve
maximum effi ciency .
• Furniture and drapery should be arranged so that
the supply air registers and return grilles are not
obstructed.
Burner Operation
Perform the startup instructions on page 7. The igniter
should ignite the closest burner and the fl ames should
quickly carryover to the other burners. The fl ames should
be bright blue, with occasional yellow streaks.
