Clearances to Combustibles
Hazards:
For maximum safety the building must be evaluated for hazards before installing the heating system.
Examples of hazards include, but are not limited to:
• Gas and electrical lines
• Combustible and explosive materials
• Chemical storage areas
• Areas of high chemical fume concentrations
• Provisions for accessibility to the heater
• Adequate clearances around air openings
• Combustion and ventilating air supply
If you are unsure of the potential hazards, consult your local fire marshal, fire insurance carrier or other
qualified authorities on the installation of gas fired tube heaters for approval of the proposed installation.
A critical safety factor to consider before installation is the clearances to combustibles. Clearance to
combustibles is defined as the minimum distance you must have between the tube surface, or reflector,
and the combustible item . Considerations must also be made for moving objects around the tube heater.
The following is a partial list of items to maintain clearances from:
Combustible items:
• Wood
• Paint
• Paper
• Parked vehicles
• Fabric
• Gasoline
• Chemicals
• Storage racks
• Plastics
Safety Signs and Labels
It is important to provide warnings to alert individuals to potential hazards and safety actions. ANSI Z83.20
and CSA 2.34 require you to post a sign "specifying the maximum permissible stacking height to maintain
the required clearances from the heater to the combustibles" near the heaters thermostat or, in absence of
such thermostats, in a conspicuous location. Contact Brant Radiant Heaters Ltd. or an authorized dealer
for Clearance Safety Limit Signs(P/N: BR-SIGN).
Safety warning labels must be maintained on the tube heater. Illustrations of the safety labels, and their
locations, are pictured in the Series Manual. In locations used for the storage of combustible materials,
signs must be posted to specify the maximum permissible stacking height to maintain the required
clearances from the heater to combustibles. Signs must either be posted adjacent to the heater
thermostats or, in the absence of such thermostats, in a conspicuous location.
WARNING
!
Placement of explosive objects, flammable objects, liquids and vapours close to the
heater may result in explosion, fire, property damage, serious injury or death. Do not
store or use explosive objects, liquids and vapour in the vicinity of the heater.
