In Canada, this unit is approved from 0 to 4500 feet above sea level. Installation of this
stove at altitudes above 4500 feet is subject to field test of the individual installation and approval
by the local authority having jurisdiction.
In the United States, input ratings of this unit are based on sea level operation, and shall
not be changed for operation at elevations up to 2000 feet. For operation at elevations above
2000 feet, this stove shall be reduced at the rate of 4% for each 1000 feet above sea level.
Exception: As permitted by the authority having jurisdiction.
