For maximum safety the building must be evaluated for hazards before installing the heating system.
Examples 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
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
When installing the tube heating system, the minimum clearances to combustibles for your Series tube
heater and system configuration must be maintained. These distances are shown in Chart 1.1 on page 9
and on the burner control box. 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.
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 the combustibles.
Signs must either be posted adjacent to the heater's thermostat or in a conspicuous location.
