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.
