Fire Hazard. Always
maintain published
clearance to
combustibles. Failure
to comply with the
stated clearances to combustibles
could result in personal injury, death
and/or property damage.
This heater should be
installed so that the
minimum clearances
to combustibles,
as marked on the
heater, will be maintained from
vehicles parked below. If vehicle
lifts are present, ensure that these
clearances will be maintained from
vehicles parked below. If vehicle
lifts are present, ensure that these
clearances will be maintained from
the highest raised vehicle.
WARNING
!
This is not an
explosion-proof
heater. Do not
store or use
flammable objects,
liquids or vapor in the vicinity of
the heater. Where there is the
possibility of exposure to flammable
vapors or highly combustible
materials, consult the local fire
marshall, fire insurance carrier and

Clearance to Combustibles
For maximum safety, the building
must be evaluated for hazards before
installing this heating system. A critical
safety factor before installation is the
clearance to combustibles.
Clearances to combustibles is defined
as the minimum distance that must be
maintained between the tube surface
or reflector and combustible materials.
It also pertains to the distance that
must be maintained from moving
objects (e.g. overhead doors, cranes,
vehicle lifts, etc.) around the tube
heater.
If you are unsure about the proposed
installation, consult your local fire
Marshall, fire insurance carrier or other
qualified authorities for the 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 published clearances from
the heater to combustibles” near the
heater’s thermostat or, in the absence
of such thermostats, in a conspicuous
location.
All safety labels must be maintained
on this appliance. Contact Grainger if
replacement labels are needed.
