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:
• Vehicle parking areas
• Vehicles with lifts or cranes
• Storage areas with stacked materials
• Lights
• Sprinkler heads
• Overhead doors and tracks
• Dirty, contaminated environment
• 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
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:
If you are unsure of the potential hazards, consult your local fire Marshall, fire insurance carrier or other
qualified authorities on the installation of gas fired tube heaters for approval of the proposed installation.
Safety Signs and Labels
It is important to provide warnings to alert individuals to potential hazards and safety actions. ANSI
Z83.20b 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 vapors close to the
heater may result in explosion, fire, property damage, serious injury or death. Do not
store or use explosive objects, liquids and vapor in the vicinity of the heater.
