HEATER PERFORMANCE DATA
NOTE: To compensate for the effects of high altitude areas above 2000 feet, input rating, and
therefore recovery ratings, should be reduced approximately 4% for each 1000 feet above sea level.
Recovery rating of models shown in chart above are obtained by actual efficiency test data by recognized Certification Agency.
Minimum Pressure must be maintained under both load and no load (static and ring) conditions. Electrical characteristics: 120 volts/60 Hz and less
than 5 amps.
