Commercial Gas Water Heater
SPECIFICATIONS
GPG models are available in both natural gas and propane (except for GPG 81 370 model which is
natural only). To order propane, change the “N” to “P” in the model number. Example: GPG 81 140
P
EA
Based on 80% thermal efficiency.
NOTE: To compensate for the effects of high altitude areas above 2000 feet, recovery capacities should
be reduced approximately 4% for every 1000 feet above sea level.
Above capacities are based on actual efficiencies obtained in engineering laboratories.
