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.
