Detroit Radiant Products Company HLV Series - Manual (Page 8)

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 or vapor in the vicinity of the heater.
Clearance to combustibles is defined as the minimum distance that must exist between the tube surface,
or reflector, and any combustible items (see Figure 1.2). It also pertains to the distance that must be
maintained from moving objects around the tube heater. Moving items include, but are not limited to,
vehicle lifts, overhead doors, cranes and hoists. For instance, if vehicle lifts are present, ensure that
clearances will be maintained from the highest raised vehicle.
If you are unsure of the potential hazards in the application, consult your local fire Marshall, fire insurance
carrier or other qualified authorities on the installation and approval of the proposed installation.
Clearance to Combustibles
Clearances listed in Chart 1.2 apply to each individual burner in the HLV system. When installing the
tube heater vacuum system, clearances to combustibles for each burner model and its applicable tube
run must be maintained. Inspect each burner rating label to ensure that clearances are maintained.
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 be posted adjacent to the heater’s thermostats or, in the absence of such
thermostats, in a conspicuous location.
The stated clearance to combustibles represents a surface temperature of 90°F (32°C) 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.
