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.
FUELS
WARNING: Use only kero-
sene, #1/#2 diesel/fuel oil, JET A
or JP-8 fuels to avoid risk of fire or
explosion. Never use gasoline, 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.
