High Altitude Operation
High Altitude Operation
Explosion hazard. This heater must be converted by a trained gas installation and
service personnel only. Failure to comply could result in personal injury, asphyxiation,
death, and fire or property damage.
High altitude operation of this tube heater is approved, without modification, for elevations up to 6,000 feet
(1,829 m) above MSL (sea level) in Canada and the United States. If the heater is being installed at an
elevation above 6,000 ft, the input rate will have to be de-rated to ensure proper operation. The deration is
achieved by a gas orifice change. Contact the factory for installations above these elevations.
