1.1. PLUG & MAINS POWER SUPPLY.
 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 dealer.
YOU MUST also read and understand the following instructions concerning electrical safety.
NOTE: 110 volt heaters are usually operated by connecting to a transformer or a generator. Check to ensure all supply equipment is compatible
with the rating of the heater.
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. Important: For use with a 110 volt supply - ensure that the 110 volt transformer or generator
is adequately rated.
1.1.8. DO NOT pull or carry the appliance by the power cable.
1.1.9. DO NOT pull the plug from the socket by the cable.
1.1.10. 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 or 110 volt
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.
1.1.11. 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.

sequence. Hold the gas valve button in for 15-20 seconds this time, before releasing.
6.1.4. The heat output is controlled by adjusting the gas pressure via the regulator (fig.4). Turn the regulator knob anti-clockwise to reduce the
gas pressure and heat, and clockwise to increase the gas pressure and heat.
6.2. Switching Heater Off.
6.2.1. After use, shut off the gas cylinder tap. Allow the fan to continue running until the flame shuts down, then switch the On/Off switch to the
OFF (O) position and isolate the heater from the electrical supply.
 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.
The heater may also be used as a cool air fan, as follows:
7.1. Remove the gas supply hose and plug the heater into the electrical power supply.
7.2. Switch on the fan. The unit will now blow out cool air only.
 WARNING! Before commencing service or maintenance, disconnect the heater from
the electrical and gas supplies. 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
