Maintain clearance to combustible materials as further specified in this manual. Failure to do so could
result in a serious fire hazard. Heaters should not be located in hazardous atmospheres containing
flammable vapors or combustible dusts. Signs should be provided in storage areas specifying maximum
safe stacking height and safe parking locations for vehicles of various heights.
CAUTION: MECHANICAL HAZARD
This equipment expands and contracts with each operating cycle. The gas connection, suspension
hardware, and the installation itself must safely allow this movement. Failure to do so could result in
serious fire or explosion hazard.
CAUTION: FIRE OR EXPLOSIONS HAZARD
This heater is equipped with an automatic ignition device. Do not attempt to light the burner by hand.
Failure to comply could result in a serious fire and personal injury hazard.
CAUTION: MECHANICAL HAZARD
Do not use high pressure (above ½ psi [3.5 kPa]) to test the gas supply system with the burners
connected. Failure to comply could result in damage to the burner and its control components requiring
replacement.
CAUTION: SERVICE LIFE RISK
Do not install equipment in atmospheres containing halogenated hydrocarbons or other corrosive
chemicals. Failure to comply may lead to premature equipment failure and invalidation of the warranty.
Additionally, it is recommended that the equipment be installed with a slope downward and away from
the burner of ¼” in 10 ft (7 mm per 3 m) to allow drainage of start-up condensate.
