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:
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
Outlet 6 Ft. (1.83 m) Top 6 Ft. (1.83 m)
Sides 6 Ft. (1.83 m) Rear 2 Ft. (0.61 m)

ELECTRICAL CONNECTIONS
Connect the mains lead to a standard, 230 Volt (50Hz) electrical supply
through an approved BS1363/A plug fitted with a BS1362 3 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.
• The BLUE wire must be
connected to the
terminal which is
marked N or coloured
black.
• The BROWN wire must
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)

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.
Similarly, should there be a power failure, causing the fan motor to stop, the
Safety Shut-Off valve solenoid will 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.

PROPANE GAS SUPPLY
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.
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.
WARNING: THE FITTING AND CHANGING OF THE GAS CYLINDERS MUST BE
CARRIED OUT IN A FLAME FREE ATMOSPHERE.
WARNING: YOU SHOULD ONLY USE PROPANE GAS CYLINDERS
AVAILABLE FROM BUILDERS MERCHANTS OR GAS SUPPLIERS.
WARNING: PROPANE GAS CYLINDERS MUST BE USED AND STORED IN
ACCORDANCE WITH THE ‘HIGHLY FLAMMABLE LIQUIDS AND LIQUEFIED
PETROLEUM GASES REGULATIONS 1972’

on hose/regulator assembly to the
propane tank(s).
• Turn POL fitting anti-clockwise
into the threads on the tank.
Tighten firmly using a wrench.
IMPORTANT: Position the regulator so
that the hose leaving the regulator is
in a horizontal position. This places
the regulator vent in the proper
position to protect it from the weather.
3. Connect the hose to the valve
inlet. Tighten firmly using a
wrench.
IMPORTANT: Use extra hose or piping
if needed between hose/regulator
assembly and propane tank. You
must use the regulator supplied with
heater.
4. Open the propane supply valve
on the propane tank(s) slowly.
NOTE: If the supply valve is not opened slowly, the check valve on the
propane tank will activate and stop gas flow. If this happens, close the
propane supply valve and open again slowly.
