Clearances to Combustibles
Children and adults should be alerted to the hazards of high surface temperatures and should stay
away to avoid burns or clothing ignition.
Young children should be carefully supervised when they are in the same space as the heater.
Clothing or other flammable materials should not be hung from the heater, or placed on or near the
heater.
Any guard or other protective device removed for servicing the heater must be replaced prior to
operating the heater.
Installation and repair should be done by a qualified service person. The heater should be inspected
before use and at least annually by a qualified service person. More frequent cleaning may be
required as necessary. It is imperative that the control compartment, air passageways, and burner(s)
of the heater be kept clean.
CAUTION
!
Hazards:
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
Clearances to Combustibles
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:
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.
• Plastic
• Parked vehicles
• Gasoline
• Storage racks
Combustible items:
Moving Objects:
• Wood
• Overhead doors
• Paper
• Vehicle lifts
• Fabric
• Cranes
• Chemicals
• Hoists
• Paint
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 2.1 on page 9
and on the burner control box.
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.
• Vehicle parking areas
• Vehicles with lifts or cranes
• Storage areas with stacked materials
• Lights
• Sprinkler heads
• Overhead doors and tracks
• Dirty, contaminated environment
