USA and 0 to 4,500 feet (0-1372 M) in Canada. At
higher elevations the BTU input must be de-rated

the proper ratio of gas to air. If the installer must
convert the unit to adjust for varying altitudes, a
deration information sticker must be filled out by the
installer and adhered to the appliance at the time
of the conversion. Contact your local gas supplier
for deration requirements for your area.
