1.1. ELECTRICAL SAFETY

WARNING! It is the responsibility of the owner and the operator to read, understand and comply with the following:

You must check all electrical products, before use, to ensure that they are safe. You must inspect power cables, plugs, sockets and

any other connectors for wear or damage. You must ensure that the risk of electric shock is minimised by the installation of

appropriate safety devices. A Residual Current Circuit Breaker (RCCB) should be incorporated in the main distribution board. We also

recommend that a Residual Current Device (RCD) is used. It is particularly important to use an RCD with portable products that are

plugged into a supply which is not protected by an RCCB. If in any doubt consult a qualified electrician. You may obtain a Residual

Current Device by contacting your Sealey stockist..

You must also read and understand the following instructions concerning electrical safety.

1.1.1. The Electricity at Work Act 1989 requires all portable electrical appliances, if used on business

premises, to be tested by a qualified electrician, using a Portable Appliance Tester (PAT), at least

once a year.

1.1.2. The Health & Safety at Work Act 1974 makes owners of electrical appliances responsible for

the safe condition of those appliances and the safety of the appliance operators. If in any doubt

about electrical safety, contact a qualified electrician.

1.1.3. Ensure that the insulation on all cables and on the appliance is safe before connecting it to the

power supply. See 1.1.1 and 1.1.2 and use a Portable Appliance Tester.

1.1.4. Ensure that cables are always protected against short circuit and overload.

1.1.5. Regularly inspect power supply cables and plugs for wear or damage and check all connections

to ensure that none are loose.

1.1.6. Important: Ensure that the voltage marked on the appliance matches the power supply to be

used and that the plug is fitted with the correct fuse - see fuse rating on right.

1.1.7. DO NOT pull or carry the appliance by the power cable.

1.1.8. DO NOT pull the plug from the socket by the cable.

1.1.9. DO NOT use worn or damaged cables, plugs or connectors. Immediately have any faulty item repaired or replaced by a qualified electrician. When

an ASTA/BS approved UK 3 pin 13 amp plug is damaged, cut the cable just above the plug and dispose of the plug safely.

Fit a new plug according to the following instructions (UK only - see diagrams on right).

a) Connect the GREEN/YELLOW earth wire to the earth terminal ‘E’.

b) Connect the BROWN live wire to the live terminal ‘L’.

c) Connect the BLUE neutral wire to the neutral terminal ‘N’.

d) After wiring, check that there are no bare wires, that all wires have been correctly connected, that the cable outer

insulation extends beyond the cable restraint and that the restraint is tight.

1.1.10. If an extension reel is used it should be fully unwound before connection. A reel with an RCD fitted is preferred since any appliance plugged

into it will be protected. The cable core section is important and should be at least 1.5mm2, but to be absolutely sure that the capacity of

the reel is suitable for this product and for others which may be used in the other output sockets, we recommend the use of 2.5mm2

section cable.

1.2. GENERAL SAFETY

WARNING! Disconnect heater from mains electrical supply and gas cylinder before servicing or performing maintenance. Replace or

repair damaged parts. Use genuine parts only. Unauthorised parts may be dangerous and will invalidate the warranty.

WARNING: DO NOT use for the heating of habitable areas of domestic premises: for use in public buildings, refer to national

regulations.

Store gas cylinders in accordance with regulations applicable to such appliances.

Ensure that nothing stands or passes in front of the heater. Mandatory minimum distance from the heater is 2 metres at the front.

Only use the propane gas pressure regulator and hose assembly supplied with the heater, without alteration.

Ensure continuous ventilation is provided to the heater operating area. A ventilation opening must run to the outside of the premises where the

heater is to be operated. The opening must be 100cm2for every kW and must also be set at an equal distance from the upper and lower parts of the

heater operating area.

WARNING: If the heater is used for prolonged periods at maximum power, ice may form on the propane cylinder. This is because of

excessive evaporation. In such a case DO NOT use the heater to de-ice the cylinder.

WARNING: If the smell of gas is present, isolate the gas cylinder immediately and investigate the reason before re-connecting it.

DO NOT use the heater if damaged. Take immediate action to repair or replace damaged parts. Use an authorised service agent only.

DO NOT use the heater for residential use.

DO NOT allow untrained persons to ignite the heater.

DO NOT operate the heater without the cover.

DO NOT use a naked flame to try and ignite the heater.

DO NOT use the heater near flammable, combustible or explosive materials - liquids, solids or gases.

DO NOT leave the heater unattended whilst in use.

DO NOT obstruct the air inlet and outlet sections of the heater. Keep immediate area clean and tidy.

DO NOT point the heater towards the gas cylinder.

Keep children away from the heater.

Keep the heater clean and in good working order.

Ensure that the heater is correctly turned off and the gas source isolated when not in use.

When not in use for any length of time, store heater in a safe, dry, childproof location.

NOTE: This appliance is not intended for persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience

and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their

safety. Children should be supervised to ensure that they do not play with the appliance.

2. INTRODUCTION

Many users have found the advantages of propane heaters far outweigh the small additional running costs. The fuel is more completely burned

and does not leave an oily residue as experienced with paraffin heaters. There is no odour, except for the few seconds during start-up and the

units run a little more quietly since they do not need a compressor to drive the fuel to the burner. Available with a durable paint finish or with a

stainless steel body for improved corrosion resistance and stylish appearance.

Heaters are fan assisted, fitted with a piezoelectric ignition system for trouble-free starting and feature a direct gas head assembly. Safety

solenoids prevent the heater from leaking gas without first being electrically started. Supplied with an approved propane gas regulator and hose.

All models are tested and certified to CE/EN. Manufactured to BS EN 1596.

4.3. Switching heater off.

4.3.1. Close the tap on the gas bottle to isolate the gas supply.

4.3.2. Allow the fan to run for at least 30 seconds after the flame has extinguished before switching off.

4.3.3. When the heater is not in use for any length of time, disconnect it from the electrical and gas supply and store it in a safe, dry, childproof

location.

WARNING! If the flame shuts down during operation, before repeating the ignition sequence, make sure that the fan is not jammed, and

the air inlet and outlet are completely free of obstructions. If it is due to overheating, the cause of the problem must be determined and

corrected before repeating the ignition procedure.

5. MAINTENANCE

6. TROUBLESHOOTING

WARNING Before commencing service or maintenance, disconnect the heater from the electrical and gas supplies and allow to cool fully.

Use authorised parts only. Unauthorised parts may be dangerous and will invalidate the warranty.

Should the heater require service or maintenance, a suitably qualified engineer should carry this out or contact your local Sealey service

agent.

5.1. Check the gas supply hose condition regularly, and change if necessary.

5.2. Clean the heater with a damp cloth, DO NOT use abrasive or solvent or abrasive cleaners.

WARNING: Air Contaminants.

Air contaminants taken into the heater will damage the unit, cause health problems and safety issues.

For example: Body shop filler dust and overspray dust will clog the burner diffuser, contaminate the combustion chamber and

damage the internal parts of the heater. If contaminants are present the heater must be supplied with ducted clean air.

Please note that any parts damaged by filler dust or overspray dust will not be covered by warranty. Additionally a cleaning

charge will be made for any heaters damaged by filler dust or overspray dust.
