extinguisher should be available in the
operating area.
SAFETY, INSTALLATION, AND OPERATION

DANGER: CARBON
MONOXIDE HAZARD
WARNING: This machine emits carbon
monoxide, a deadly gas, and must be vented
if used in an enclosed area. Improper venting
can cause poor combustion, delayed ignition,
and could result in death or serious injury.
MECHANICAL SAFETY
1. All guards, shields, and covers must be in place
to prevent accidental contact with hazardous
parts.
2. Drive belts must be inspected and tightened
periodically to operate at optimum levels
3. Inspect machine for damaged or worn
components and repair or replace to avoid
potential hazards. Do not operate the
machine if any mechanical failure is noted or
suspected.
ELECTRICAL SAFETY
1. This machine must be electrically grounded.
Failure to have the machine grounded may
result in the operator being electrically shocked
and even death.
2. Do not plug-in or un-plug machine with wet
hands.
3. Keep power cords and connections (connectors)
out of water.
4. If an extension cord must be used to operate
this machine, it should be as short as
possible. The extension cord must be properly
sized and fitted with a grounding type plug and
receptacle.
5. All wiring and electrical connections should
comply with the National Electrical Code (NEC)
and with local codes and practices.
6. Fuses or circuit breakers should be compatible
with machine requirements. (See ELECTRICAL
section of MODEL SPECIFICATIONS for power
requirements.)
7.High voltage may be present within this
machine. Servicing should only be
performed by properly trained personnel.
FUEL SAFETY
DANGER: To avoid possible injury, fire, or
explosion, please read and follow these
instructions.
1. Use only Kerosene, #1 or #2 fuel oil, or #1
Diesel. The use of incorrect fuel may result in
fire or explosion and severe injury to the
operator.
WARNING: DO NOT USE GASOLINE,
CRANKCASE DRAININGS, OR OIL
CONTAINING GASOLINE OR SOLVENTS.
AVERTISSEMENT: NE PAS UTILISER
D’ESSENCE DE PRODUITS DE VIDANGE NI
D’HUILE CONTENANT DE L’ESSENCE OU
DES SOLVANTS
2. Fuel burning equipment must have proper
ventilation for cooling, combustion air, and
exhausting of combustion products.
3. Personnel trained in and familiar with the type
of equipment being serviced should only
perform adjustments to fuel burning
equipment.
4. Do not refuel machine while it is running or
hot. Allow it to cool sufficiently to prevent
ignition of any spilled fuel. Clean up any spilled
fuel before resuming operation.

INSTALLATION
1. LOCATION: This machine should be installed
by only qualified technicians. The machine
should be set upon a solid level surface where
it will not be affected by strong winds, rain, or
snow. Install the machine considering the
direction of the exhaust. DO NOT DIRECT
EXHAUST TOWARD ANY COMBUSTIBLE OR
HEAT SENSITIVE MATERIAL. Install the
machine considering . locations of electrical
connections, venting, and maintenance. All
wiring and electrical connections should
comply with the National Electrical Code (NEC)
and with local codes and practices. Use the
chart on the next page for your cord selection.
2. LOCAL CODES: Installation and servicing
must only be performed by qualified personnel
and must conform to local codes and
ordinances.
WARNING: ELECTRIC
SHOCK HAZARD
3. ELECTRICAL: Connect the machine to an
electrically grounded circuit that is fuse or
circuit breaker protected. Do not use any type
of adapter. If the correct type of receptacle is
not available, have one installed by a qualified
electrician.The circuit must match that
specified in the ELECTRICAL section under
MODEL SPECIFICATIONS.
4. EXTENSION CORD: The use of an extension
cord that has undersize wire compared to the
amp draw of your machine will adversely limit
the starting load carrying abilities of the motor
and machines performance. Use only 3-wire
extension cords that have 3-prong plugs and
3-pole cord connectors that accept the plug
from the product. Use only extension cords
that are intended for outdoor use. These
extension cords are identified by a marking
“Acceptable for use with outdoor appliances;
store indoors while not in use.” Use only
extension cords having an electrical rating not
less than the rating of the product. Do not use
damaged extension cords. Use an extension
cord in good repair free of frays or cracks in
the outer covering. Do not abuse extension cord
and do not yank on any cord to disconnect.
Keep cord away from heat and sharp edges.
Always disconnect the extension cord from the
receptacle before disconnecting the product
from the extension cord.
WARNING: To reduce risk of electrocution,
keep all connections dry and off the ground.
Do not touch plug with wet hands.
CHART FIGURES ARE BASED ON NOT
MORE THAN 100 FOOT
(Based on Ambient Temperature of 86°F (30°C).
*Use Amp Draw indicated the same or higher than
your machine output
EXAMPLE: Machine Amp Draw 51, use 55 (2
Conductor).
The thermostat type of cord shall be C, PD, E, EO,
EN, S, SO, SRD, SJ, SJO, SV, SVO, SP.
The thermoset plastic types shall be ET, ETT,
ETLB, ETP, ST, STO, SRDT, SJT, SJTO, SVT,
SVTO, and SPT.B
5.FIRE HAZARD: Keep combustible materials
away from gas machines. DO NOT allow lint
or dust collect in the burner area.
6. FUEL SUPPLY: This machine must have a fuel
supply as specified in the FUEL sectio of the
MODEL SPECIFICATIONS.
7. COLD WEATHER: As the weather becomes
colder, fuel becomes thicker and may become
so viscous that the fuel will not flow properly.

As viscosity increases, the thicker oil can cause
delayed ignition, poor spray patterns, and
rumbling fires. As moisture will quickly
destroy fuel pumps, make certain that tank
openings are secure and moisture cannot
enter. In cold weather areas, frost build up will
occur in fuel tanks. As the weather warms it
turns to condensate, and the water will be in
the tank. Keep the tank clear of water, as
moisture reaching the fuel pump will cause
rust, and the pump will bind. A full fuel tank
will lessen condensation build up.
OPERATING
INSTRUCTIONS
PRE START-UP
The first time the machine is operated, after
repairs have been made, or if the machine has set
for a period of time (30 days or more) follow the
following procedures.
1. Check the tension of the belt per instructions
in MACHINE MAINTENANCE.
