damage be apparent, please notify your Clarke dealer immediately.
Your heater is fully assembled,- only the electrical and gas supplies need
connecting. Retain any plastic cover caps (attached to the inlet connector
and hose/regulator assembly) for future storage.
PROPANE GAS SUPPLY
These heaters are designed for use with PROPANE GAS ONLY. Gas cylinders are
not supplied, but are readily available from builders merchants or gas suppliers
etc.
This range of portable, direct fired gas heaters is designed to BS 4096 for
industrial applications to give safe, efficient and reliable operation.
As with all mechanical equipment, optimum performance will only be
achieved if the correct operation and servicing procedures are followed.
GAS CONNECTION
Connect the free end of the gas hose to the gas inlet connection on the
heater and tighten to ensure there are no gas leaks. Before attaching the
regulator to the gas cylinder, ensure the mating parts are free from grease and
dirt and are undamaged.
Fit the regulator to the cylinder,
tightening the thread as tight as
possible with a propane spanner,
noting that the threads are LEFT
HANDED. To check for leaks, use
soapy water or liquid soap applied to
each of the connections. Any
bubbles formed indicate a leak.

In order to reduce the risk of icing up
when operating at long periods at
maximum capacity, you should use a
larger capacity gas bottle, or two/
three bottles in parallel, as shown in
Fig 2.
• The ‘Tee’ piece and ‘pigtails’
are readily available from your
builders merchants or gas
supplier.
CHANGING GAS BOTTLES
1. Turn off the heater and disconnect from the electrical supply.
2. Close the gas valve on the bottle and unscrew the regulator, (left hand
thread).
3. Ensure the replacement bottle screw threads and gas orifice is perfectly
clean before screwing in the regulator valve tightly.
4. Check to ensure there are no leaks using soapy water and when satisfied,
plug in to the electrical supply and restart the heater.
OPERATING SPACE AND AIR SUPPLY
MINIMUM FRESH AIR OPENING REQUIREMENTS
As a general rule of thumb, an opening of 1in2per 1000 Btu/hr is a minimum
requirement.
These heaters are specified as requiring a minimum ventilation of 3 sq/ ft per
100,000BTU/hr.
OPERATING SPACE
Do not obstruct the air intake to the heater and allow 4 feet (125cm) between
rear, top and sides and walls or other obstructions.

PRINCIPLE OF OPERATION
Understanding the basic operation of the heater will reinforce the need to
maintain the unit in top condition at all times, whilst always observing the
safety precautions.
The heater comprises four basic systems:
1. The gas system.
2. The air system.
3. The ignition system.
4. The safety control system.
AIR SYSTEM
An axial fan, which is energised when switching on, provides the air flow
through the combustion chamber to provide a stream of hot air from the
heater.
GAS SYSTEM
The gas supply to the machine is by means of a high pressure hose,
connected to an LPG (Liquid Propane Gas) cylinder, via a pressure regulator.
When the mains supply is switched on, the Safety Shut-off valve solenoid is
energised, allowing the gas to flow to the Flame Failure valve, and when the
failure valve override knob is depressed, gas flows to the burner head.

9
Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
IGNITION SYSTEM
Ignition is automatic with this heater as soon as the gas valve button is
depressed, with a continuous spark from the spark plug igniting the gas. As the
thermocouple heats up, a low voltage is fed to the Flame Failure valve,
causing the valve to open, so that after a few seconds, the gas valve button
may be released and the flame is established.
SAFETY CONTROL SYSTEM
Should the flame extinguish for any reason, the thermocouple will quickly cool,
causing the Flame Failure valve to close, shutting off the gas supply.
Similarly, should there be a power failure, causing the fan motor to stop, the
Safety Shut-Off valve solenoid will become de-energised, and therefore shut
off the gas supply.
Additionally, the machine is equipped with thermal overload protection,
which will intervene should the unit overheat, shutting off the electrical supply.
STARTING PROCEDURE
1. Ensure there is sufficient gas and that it is correctly connected.
2. Open the supply valve on the gas
cylinder, and fully open the
regulator valve adjacent to the
gas inlet pipe.
3. Plug the heater in to a suitable
power supply.
4. Set the flame intensity control
valve (B), to a low setting,
5. Set the fan switch (A) to the ON (I)
position. Confirm the fan
operates.
6. Hold in the gas valve button (C), until the thermocouple is energised and
the heater ignites.
7. If the heater fails to ignite, there may be air in the hose so keep the fuel
valve open and wait for about 15 seconds. Wait 30 seconds for unburned
fuel to exit the heater. Repeat the step above.
WARNING: BEFORE STARTING THE HEATER, YOU MUST ENSURE THAT THE
MINIMUM VENTILATION REQUIREMENTS ARE OBSERVED TO AVOID THE
RISK OF CARBON MONOXIDE POISONING.

8. When the burner remains lit, set the heater at the required level by turning
the flame intensity control valve counter-clockwise. If the burner goes out,
turn off the gas. Turn the gas valve fully clockwise to its lowest position.
Check the fuel supply. If adequate fuel is available, re-start the heater from
step 1.
Should the flame extinguish when the ignition button is released, wait for 1
minute, before repeating the operation.
• Turning the flame intensity control valve anti-clockwise will increase the
gas supply and therefore the output, clockwise to decrease.
If ignition is difficult or irregular, ensure the fan is operating and that the air inlet
and outlet are completely clear. Also ensure that the electrode gap is correct,
and that the electrode is clean (see Maintenance).
IMPORTANT:
Should the thermal overload protection feature operate and the spark plug is
seen to be operating, shut off the gas supply and allow the unit to cool for at
least 10 minutes with the fan running, before attempting to relight the burner.
Should the flame safety valve operate, the heater may be restarted once the
cause of the problem has been found and rectified.
SHUT-DOWN PROCEDURE
1. Turn off the gas at the propane cylinder valve(s).
2. Let the heater run while any gas left in the supply hoses is burnt off.
3. Allow the fan to run for 2 - 3 minutes with the burner off, in order to allow
the casing to cool down and the fan to disperse any residual gas.
4. Switch off the fan and unplug from the electrical supply.
5. Disconnect the gas supply.

STORAGE
1. Store the propane gas cylinders in a safe manner outdoors and keep them
below 100deg F (37 deg C).
2. Place protective bags over fittings & connectors and store in a clean, dry
place.
3. Fit the plastic cover caps which were removed when unpacking, over the
connections they covered when received.
4. When removing from storage, always check inside of heater for debris/
foreign objects before returning to use. Do not store the hose/regulator
inside the combustion chamber.
MAINTENANCE
It is essential that the heater is correctly maintained and kept in top condition
at all times.
All models are similar, in that access to the control components is gained by
removing the access panel under the base of the heater which is secured by
screws around the edge.
MONTHLY (WHEN IN CONSTANT USE)
Check the spark plug for cleanliness and correct operation. Have the gap re-
set to no more than 5mm by your Clarke service engineer.
Check the condition of the gas hose. If there are any signs of deterioration, it
should be renewed using only a Clarke original spare part.
Ensure that all connections are clean and secure.
When necessary, clean the fan and the inside of the heater thoroughly.
The use of parts other than genuine Clarke replacement parts may result in
safety hazards or decreased performance, and will invalidate your warranty.
CAUTION: DISCONNECT THE HEATER FROM THE PROPANE SUPPLY
CYLINDER(S)
WARNING: BEFORE CARRYING OUT ANY ADJUSTMENT OR
MAINTENANCE, ENSURE THE HEATER IS SWITCHED OFF, DISCONNECTED
FROM THE MAINS AND GAS SUPPLY, AND HAS BEEN GIVEN ADEQUATE
TIME TO COOL DOWN.
