FRESH AIR REQUIREMENTS
• DO NOT use in unventilated areas.
• The flow of combustion and ventilation air must not be obstructed.
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 carbon monoxide poisoning are:
•headaches
•dizziness
• nausea
• dry mouth or sore throat
• blurred vision
• shortness of breath
• confusion
• loss of consciousness
Should anyone show these symptoms they must GET FRESH AIR IMMEDIATELY.
Turn off the heater and have it serviced before using it again.
Be sure to follow all warnings in this manual.
WE RECOMMEND THE USE OF A CARBON MONOXIDE DETECTOR
WARNING: PROVIDE AT LEAST A 3FT2OPENING OF FRESH, OUTSIDE AIR
WHILST USING THIS HEATER. IF FRESH OUTSIDE AIR VENTILATION IS NOT
PROVIDED, CARBON MONOXIDE POISONING CAN OCCUR.

IF YOU SMELL GAS
Liquid Propane gas has a man-made
odourant added specifically for detection
of gas leaks.
If a leak occurs you should be able to
smell the gas. Since Propane (LP) is
heavier than air you should smell for the
gas odour near to the floor. ANY GAS
ODOUR requires immediate attention.
1. DO NOTHING that could ignite the
gas. DO NOT operate any electrical
switches. DO NOT unplug any power
supply or extension cables. Do not
light matches or cause any other
source of flame. DO NOT use your
phone.
2. Get everyone out of the building and
away from the area immediately.
3. Close all propane (LP) gas bottle fuel
supply valves.
4. Propane (LP) gas is heavier than air
and may settle in low areas. When you
have reason to suspect a propane
leak, keep out of all low areas.
5. Use your neighbours phone and call
your fire department. DO NOT re-enter
the building or area.
6. Stay out of the building and away
from the area until declared safe by
the firefighters.
7. FINALLY. let the firefighters check for
escaped gas. Have them ventilate
the building and area before you
return. Properly trained service people
must repair any leaks, check for
further leakages and then re-light the
heater for you.
8. IF YOU SMELL EVEN A SMALL
AMOUNT OF GAS, CONTACT
YOUR FIRE DEPARTMENT. DO
NOT WAIT!
NO ODOUR DETECTED
1. Some people cannot smell the odour
added to propane (LP). You must
determine if you can smell the
odourant in this fuel.
2. Learn to recognize the odour of
propane (LP) gas. Local propane (LP)
gas dealers will to give you a “scratch
and sniff” pamphlet. Use it to become
familiar with the fuel gas odour.
3. Smoking can decrease your ability to
smell. Being around an odour for a
period of time can affect your
sensitivity to that particular odour.
Odours present in animal confinement
buildings can mask fuel gas odour.
ODOUR FADING
1. The odourant in propane (LP) gas is
colourless and the intensity of its odour
can fade under some circumstances.
2. Propane (LP) gas odour may differ in
intensity at different levels. Since
Propane (LP) gas is heavier than air,
there may be more odour at lower
levels.
3. Always be sensitive to the slightest gas
odour. If you continue to detect any
gas odour, no matter how small, treat
it as a serious leak.
CRITICAL POINTS TO REMEMBER!
1. Propane (LPG) gas has a distinctive
odour. Learn to recognize the odour.
2. A periodic sniff test around the joints;
i.e. hose, connections. etc., is a good
safety practice under any conditions.

FEATURES OF THE GRH15
Understanding the basic operation of the heater will reinforce the need to
maintain it in top condition at all times whilst always observing the safety
precautions.
The heater comprises of three basic systems:
1. The gas system.
2. The ignition system.
3. The safety control system.
GAS SYSTEM
The gas supply to the heater is by means of a high pressure hose, connected
to a LPG cylinder via a pressure regulator. When the gas shut off valve is
opened, gas will flow to the control valve and finally into the burner.
This heater is designed for use with PROPANE GAS ONLY. Gas bottles are readily
available from builders merchants or gas suppliers etc.
This heater is designed to operate with a minimum 20 pound (9 kg) propane
bottle. Note that less gas is vaporised at lower temperatures. Your local
propane gas dealer will help you select the proper gas supplies.
IGNITION SYSTEM
A Piezo-electric igniter is positioned at the burner head. When the igniter
button is depressed a high intensity spark is generated which ignites the gas.
Heat from the flame is sensed by a thermocouple connected to the control
valve. As the thermocouple heats up, the control valve opens so that after a
short period, the control valve button (see Operation page 10) may be
released and the gas flame is established.
SAFETY CONTROL SYSTEM
Should the flame extinguish for any reason the thermocouple will quickly cool,
causing the control valve to close, shutting off the gas supply.
Additionally, the heater is fitted with a ‘Tip Over Switch’ which operates should
the heater be tilted by more than 35-40 degrees, thereby shutting off the gas
supply.

INSTALLATION
UNPACKING
Remove the heater from the carton and remove all protective material used
for shipment. Check the heater for possible shipping damage. Should any
damage be apparent, please notify your CLARKE dealer immediately.
ASSEMBLING THE SUPPORT STAND
1. Connect the stand base section to
the upper part and secure with the
wing nut supplied.
LOCATING THE HEATER
Although a ‘tip-over’ switch is fitted, the heater and propane gas cylinder
must both be located on a hard, level surface to minimize the risk of
accidental tipping. The propane gas cylinder should be adequately
restrained if needed. Only operate this heater with the supply cylinder in the
upright position.
This heater must only be used in locations where the potential for damage to
the heater or personal injury (burns), is reduced to a minimum.
The heater must be located where it will not be exposed directly to rain and/or
dripping water.
Use of this heater in a drafty area reduces its efficiency. Wherever possible,
operate in a draft free area.
The heater must always be directed away from the propane gas cylinder.
Position the heater at a safe distance of 1 metre from combustible materials.
The heater must not be used on floors covered in combustible materials.

GAS CONNECTION
The hose for connecting the heater to the gas bottle is supplied loose and
must be fitted by the user.
Make the connection to the propane cylinder in a well ventilated area using
the regulator and hose assembly supplied. The gas hose and cylinder must
ALWAYS be positioned behind the heater at the full length of the hose
1. Attach the regulator to the gas cylinder ensuring the cylinder connection is
perfectly clean. Blow out with compressed air if necessary to blast away
any dust or dirt. (Use eye protection when working with compressed air).
2. Remove the protective plug by
unscrewing clockwise.
3. Check the bullnose connection on
the regulator for any visible
damage before connecting to the
cylinder.
WARNING: PROPANE GAS CYLINDERS MUST BE USED AND STORED IN
ACCORDANCE WITH THE ‘HIGHLY FLAMMABLE LIQUIDS AND LIQUEFIED
PETROLEUM GASES REGULATIONS 1972.
WARNING: IF YOU DO NOT FOLLOW THESE INSTRUCTIONS EXACTLY, A
FIRE OR EXPLOSION MAY RESULT CAUSING PROPERTY DAMAGE,
PERSONAL INJURY OR LOSS OF LIFE.

4. Place the regulator on the cylinder
connection and hand tighten by
turning anti-clockwise.
5. Tighten firmly using a gas spanner
(or an adjustable spanner),
continuing in an anti-clockwise
direction.
6. Simply turn the valve hand wheel anti-clockwise when you need to start
the flow of gas. Ensure that you turn the cylinder off when not in use.
7. In order to reduce the risk of icing up when operating for long periods at
maximum capacity, you should use a larger capacity gas bottle.
8. Open the cylinder gas valve and check all gas connections with a soap
and water solution. To check for leaks using soapy water or liquid soap
ONLY. NEVER USE A FLAME.
9. Use a full cylinder wherever possible with good air circulation and no frost
on the cylinders.

OPERATION
FIRST USE
Read these instructions carefully. DO
NOT allow anyone who has not read
the instructions to light, adjust, or
operate this heater.
DO NOT attempt to operate the
heater with any fuel other than LPG
(liquid propane gas).
The heater reaches a very high
temperature and during first use you
may notice an odour coming from
the heater. This is quite normal and
will disperse quickly.
(It is recommended the heater is
initially run outdoors on the first
occasion to enable the odour to
clear).
Set the burner at the required angle
to project the heat forward as shown.
LIGHTING THE HEATER
1. Ensure that the gas is correctly connected and leak free. Turn on the gas
supply at the bottle and at the shut off valve (marked ON/OFF on the
knob).
2. Press and hold the control valve plunger whilst repeatedly pressing the
piezo-electric button until the burner ignites.
• Once the burner ignites, keep the control valve plunger depressed
for 12-15 seconds or until the burner stays lit after it is released.
WARNING: BEFORE STARTING THE HEATER YOU MUST ENSURE THAT THE
MINIMUM VENTILATION REQUIREMENTS ARE OBSERVED TO AVOID THE
RISK OF CARBON MONOXIDE POISONING.
WARNING: THIS HEATER WILL BE HOT DURING NORMAL OPERATION.
AVOID PHYSICAL CONTACT. DO NOT ALLOW CLOTHING OR OTHER
COMBUSTIBLE MATERIALS TO TOUCH THE HEATER.
