Your heater was designed and constructed with safety
foremost. The following safety precautions should be
taken with your heater:

1) Read and understand this manual before

operating the equipment. Ensure that all
operators of this heater are fully familiar with
the operating and safety procedures contained
in this manual. An untrained operator exposes
him or herself as well as bystanders to potential
harm.

Unauthorized modification may impair the
function and/or safety of the equipment creating
a potential or real hazard to personnel.

3) The exterior of the heater may become hot

during operation. Avoid contact with the exterior
of the heater.

flame and sparks away.

IF AT ANYTIME YOU SMELL GAS, SHUT OFF THE
GAS SUPPLY TO THE HEATER, AND EXTINGUISH
ANY OPEN FLAME. CALL YOUR GAS INSTALLER
IMMEDIATELY.

If the heater is to be incorporated into a high pressure
system, the safety procedures applicable to high
pressure systems should be followed.

1) Always hold the gun and extension firmly in

both hands during operation.

injection and severe injury. Always keep clear
of the spray nozzle. Do not direct discharge
stream at people or electrical apparatus.

3) Always keep clear of moving belts and pulleys.
4) Never disconnect high pressure hose during

operation.
