This heater has been tested at altitudes ranging from sea level to 4,500 feet (1,370 m). In this
testing, heater with standard orifice burns correctly with just an air shutter adjustment. If you
need to resize orifice for use at high altitude, contact your dealer.
Failure to adjust air shutter properly may lead to improper com-
bustion which can create a safety hazard. Consult your dealer or
installer if you suspect an improperly adjusted air shutter.
