OPERATION AT HIGHER ALTITUDES
When heating equipment is installed at higher altitudes, its rated output will decrease due to a decrease in the density of air at the higher altitude.
For each 1000 ft of elevation above sea level, the output of the GARN® WHS unit will decrease 4% from its published value. For instance, the GARN® WHS 1500 with a rating of 250,000 BTUH installed at 5000 ft above sea level with only output 200,000 BTUH (20% less than the published value). In addition, the maximum allowable storage temperature will be lower:
