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.

WARNING: PROPANE GAS CYLINDERS MUST BE USED AND STORED IN ACCORDANCE WITH THE HIGHLY FLAMMABLE LIQUIDS AND LIQUEFIED PETROLEUM GASES REGULATIONS 1972.

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. Correct all leaks immediately.

IMPORTANT: The gas hose and cylinder must ALWAYS be located well behind the heater.

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 1in2 per 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 the following clearances from combustible surfaces.
Outlet: 8 feet (2.4 m)
Sides: 2 feet (0.6 m)
Top: 6 feet (1.8 m)
Rear: 2 feet (0.6 m)
Keep the heater as far as practical from propane tanks and never point the heater directly at any propane tank.

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

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.

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.

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 ShutOff 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

WARNING: BEFORE STARTING THE HEATER, YOU MUST ENSURE THAT THE MINIMUM VENTILATION REQUIREMENTS ARE OBSERVED TO AVOID THE RISK OF CARBON MONOXIDE POISONING.

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.

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).

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.

MAINTENANCE

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.

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.

STORAGE

1. Store the propane gas cylinders in a safe manner outdoors and keep them below 100 ºF (37 ºC).
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.
