LABOUR REQUIREMENTS
Two persons are required to safely install this equipment. Wear gloves and other required
safety protection.
INSTALLATION IN COMMERCIAL AIRCRAFT HANGARS
Low intensity radiant tube heaters are suitable for use in aircraft hangars when installed
in accordance with the latest edition of the Standard for Aircraft hangars, ANSI/NFPA
No. 409 in the USA, or the Canadian Natural Gas and Propane Installation Code, B149.1
A minimum clearance of 10 ft (3m) above either the highest fuel storage compartment or
the highest engine enclosure of the highest aircraft, which may occupy the hangar. The
clearance to the bottom of the heater shall be measured from the upper surface of either
the fuel storage compartment or the engine enclosure; whichever is higher from the floor.
A minimum clearance of 8 ft (2.4m) must be maintained from the bottom of the heater to
the floor in other sections of the aircraft hangar, such as offices and shops, which
communicate with areas for servicing or storage. For proper mounting clearances, refer to
the clearances to combustibles in these installation instructions.
Heaters must be located where they are protected from damage to aircraft and other
objects, such as cranes and movable scaffolding.
Heaters must be located so as to be accessible for servicing and adjustment.
