HIGH ALTITUDE OPERATION
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.
To adjust stove for operation above 2000 feet the burner orifices may need to be changed. The orifices
are located beneath the log set so it is necessary to first remove the logs. To do so please refer to the
following detailed instructions to achieve optimum performance of your stove.

appliance installer.
