MINIMUM CLEARANCES FROM COMBUSTIBLES

RISKS OF CARBON MONOXIDE POISONING

Even though this heater operates very close to 100 percent combustion efficiency, it still produces small amounts of carbon monoxide.

• Carbon Monoxide (CO) is toxic.
• Pregnant women, persons with a heart or lung condition, anaemia or under the influence of alcohol, or those at high altitude, are more likely to be effected by Carbon Monoxide.
• CO can build up in a confined space and failure to provide adequate ventilation can be fatal.

The early symptoms of asphyxiation caused by inadequate ventilation are:

• headache
• dizziness
• nausea
• dry mouth or sore throat

Should anyone show these symptoms, they must GET FRESH AIR IMMEDIATELY. Turn off the heater and have it serviced before using again.
Be sure to follow all warnings in this manual.

WE RECOMMEND THE USE OF A CARBON MONOXIDE DETECTOR

UNPACKING

When unpacking, check the heater for possible shipping damage. Should any damage be apparent, please notify your Clarke dealer immediately. Your heater is fully assembled,- only the electrical and gas supplies need connecting.

ELECTRICAL CONNECTIONS

WARNING: READ THESE ELECTRICAL SAFETY INSTRUCTIONS THOROUGHLY BEFORE CONNECTING THE PRODUCT TO THE MAINS SUPPLY.

Connect the mains lead to a standard, 230 Volt (50Hz) electrical supply through an approved BS1363/A plug fitted with a BS1362 13 amp fuse.
If the plug has to be changed because of damage, it must be removed and a replacement fitted, following the wiring instructions shown below. The old plug must be discarded safely, as insertion into a power socket could cause an electrical hazard.

WARNING: WIRES IN THE MAINS LEAD ARE COLOURED IN ACCORDANCE WITH THE FOLLOWING CODE:
GREEN/YELLOW = EARTH, BLUE = NEUTRAL, BROWN = LIVE.

• The BLUE wire must be connected to the terminal which is marked N or coloured black.
• The BROWN wire mus t be connected to the terminal which is marked L or coloured red.
• The YELLOW AND
  GREEN wire must be connected to the terminal which is marked E or or coloured green.

We strongly recommend that this machine is connected to the mains supply through a Residual Current Device (RCD)
If you are not sure, consult a qualified electrician. DO NOT try to do any repairs.

THEORY OF OPERATION

THE FUEL SYSTEM: The hose/regulator assembly attaches to the propane gas supply. This provides fuel to the heater.
THE AIR SYSTEM: The motor turns the fan. The fan pushes air into and around the combustion chamber. This air is heated and provides a stream of clean, hot air.
THE IGNITION SYSTEM: The piezo ignitor lights the burner.
THE AUTOMATIC 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.
Similary, should there be a power failure, the safety shut off valve (solenoid) will shut off the gas supply.
The machine is also fitted with a thermal overload protection, which will operate should the unit overheat, shutting off the gas supply to the heater.

PROPANE GAS SUPPLY

WARNING: THE FITTING AND CHANGING OF THE GAS CYLINDERS MUST BE CARRIED OUT IN A FLAME FREE ATMOSPHERE.

• YOU SHOULD ONLY USE PROPANE GAS CYLINDERS AVAILABLE FROM BUILDERS MERCHANTS OR GAS SUPPLIERS.

This range of portable, direct fired gas heaters is designed to give safe, efficient and reliable operation, and are for use with propane gas only.
As with all mechanical equipment, optimum performance will only be achieved if the correct application 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’

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.
Ensure the Propane gas bottle, gas hose and electric cable, are positioned behind the unit, away from the heat.

IN THE EVENT OF A GAS LEAK

1. Put out all smoking materials and other open flames.
2. Do NOT operate electric switches or light matches.
3. Close all supply valves on gas tank or cylinder.
4. Do NOT use your phone. USE a neighbor’s phone or your mobile phone from outside the building or wherever you detected the gas leak to call the fire service.
5. Immediately get everyone out of the building or area.
6. Do NOT re-enter the building, or area until a trained service person or the fire service advises it is safe to return.

INSTALLATION

WARNING: READ AND UNDERSTAND THE WARNINGS IN THE SAFETY INFORMATION SECTION, PAGE 3. THEY ARE NEEDED TO SAFELY OPERATE THIS HEATER. FOLLOW ALL LOCAL REGULATIONS WHEN USING THIS HEATER.

• TEST ALL GAS PIPING AND CONNECTIONS FOR LEAKS AFTER INSTALLATION OR SERVICING. NEVER USE AN OPEN FLAME TO CHECK FOR A LEAK. APPLY A MIXTURE OF LIQUID SOAP AND WATER TO ALL JOINTS. BUBBLES FORMING SHOW A LEAK. CORRECT ALL LEAKS AT ONCE.

1. Provide a propane supply system (see Propane Gas Supply).
