WARNING
NOTICE
NOTICE
When a sidewall or vertical rooftop combustion air supply
system is disconnected for any reason, the air inlet pipe
must be resealed to ensure that combustion air will be free of
contaminants and supplied in proper volume.
DANGER
Failure to properly seal all joints and seams
as required in the air inlet piping may
result in flue gas recirculation, spillage
of flue products and carbon monoxide
emissions causing severe personal injury
or death.
The Power-fin uses model specific combustion air intake and
vent piping sizes as detailed in Tables 2B and 2C on page 17.
Increasing or decreasing combustion air
or vent piping to sizes not specified in this
manual is not authorized.
