SECTION 1 - RECEIVING EQUIPMENT
On receipt of your equipment it is suggested that you visually check for external damage to the carton. If the carton
is damaged, a note should be made on the Bill of Lading when signing for equipment. Remove the heater from the
carton and if it is damaged, report the damage to the carrier immediately. Save the carton.
These items are shipped loose inside the carton with the heater:

Atmospheric heaters:
Rated inputs suitable for up to 2000 feet elevation. For elevations above 2000 feet, reduce input 4% for each 1000
feet above sea level, as high elevation reduces combustion performance.
Low NOx heaters:
Rated inputs suitable for up to 5000 feet elevation. For elevations above 5000 feet, consult the factory.
