Clearance to Combustibles

• Parked vehicles

• Gasoline

• Storage racks

• Plastics

• Flexible gas lines

When installing the radiant heating system, the minimum clearances to combustibles for your series

radiant tube heater and system conﬁguration must be maintained. These distances are shown in Chart

2.1 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 radiant 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.

The stated clearance to combustibles represents a surface temperature of 90ºF (32ºC) above room

temperature. Building materials with a low heat tolerance (such as plastics, vinyl siding, canvas,

tri-ply, etc.) may be subject to degradation at lower temperatures. It is the installer’s responsibility to

assure that adjacent materials are protected from degradation.

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 radiant tube

heater. The following is a partial list of items from which to maintain clearances:

• Vehicle parking areas

• Vehicles with lifts or cranes

• Storage areas with stacked materials

• Lights

• Sprinkler heads

• Overhead doors and tracks

• Dirty or contaminated environments

• 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

Common Hazards:

For maximum safety the building must be evaluated for hazards before installing the heating system.

Examples include, but are not limited to:

Moving Objects:

• Overhead doors

• Vehicles & vehicle lifts

• Cranes

• Hoists

• Trailers
