FUELS

WARNING: Use only kero- sene, #1/#2 diesel/fuel oil, JET A or JP-8 fuels to avoid risk of fire or explosion.Neverusegasoline,oil drained from crankcases, naph- tha, paint thinners, alcohol or other highly flammable fuels.

Use only kerosene, #1/#2 diesel/fuel oil, JET A or JP-8 fuels. Heavier fuels such as No. 2 fuel oil or No. 2 diesel fuel may also be used but will result in:

•noticeable odor

•additional fuel filter maintenance

•the need for nontoxic, anti-icer additives in very cold weather

Do not use fuels heavier than No. 2 grade or heavy oils such as oil drained from crankcases. These heavy oils will not ignite properly and will contaminate the heater.

IMPORTANT: Use a KEROSENE ONLY (blue) or DIESEL ONLY (yellow) storage container. Be sure storage container is clean. Foreign matter such as rust, dirt or water will cause the ignition control assembly to shut down heater. Foreign matter may also require heaterʼs fuel system to be frequently cleaned.

TO START HEATER

IMPORTANT: Review and under- stand the warnings in the Safety Information section,page2.They are needed to safely operate this heater. Follow all local or- dinances and codes when using this heater.

1.Fill tank with fuel (see Fuels).

2.Plug heater power cord into approved, grounded, 120V/60Hz, 3 prong outlet or extension cord.

Extension Cord Size Requirements

6 to 10 feet (1.8 to 3 meters) long, use 18 AWG (0.75 mm2) rated cord

11 to 100 feet (3.3 to 30.5 meters) long, use 16 AWG (1.0 mm2) rated cord

101 to 200 feet (30.8 to 61 meters) long, use 14 AWG (1.5 mm2) rated cord

3.If a thermostat is connected, adjust it to the maximum temperature.

4.Flip switch (3 on Electric Control Panel, page 7) to the position with the symbol:

- the fan should start and after several seconds the heater should ignite.

The first time the heater is used or after the fuel circuit has been completely drained, the flow of fuel oil to the nozzle may be insufficient and may activate the flame control, which will turn off the heater; if this happens, wait for about a minute and then press the reset button (1 on Electric Control Panel, page 7) to start the heater again.

TO STOP HEATER

1.Move switch (3 on Electric Control Panel, page 7) to the “0” position or adjust the control mech- anism, for example turning the thermostat to a lower position. The flame will go out and the fan will continue to function until the combustion chamber has cooled down completely.

2.Wait until fan stops before unplugging heater. Unplug heater when not in use.

THERMOSTAT

OPERATION

The heater can only work automatically when a thermostat is connected to it by attaching the cable to terminals 2 and 3 of plug (4 on Electric Control Panel, page 7).

MOVING AND

TRANSPORTING HEATER

WARNING: Before moving the heater you must turn the heater off (see To Stop Heater), disconnect the plug from the power supply and wait for the heater to cool.

Before lifting or moving the heater, make sure that the fuel tank cap is firmly in place.

The heater may be supplied in a portable version, with wheels or a suspended version, mounted on a support structure and fixed in place with wires or chains. In the former case, to move the heater, sim- ply grasp the support handle and move the heater. In the latter case, the heater must be lifted with a fork-lift truck or a similar piece of equipment.
