2. SPECIFICATIONS
These propane heaters are fan assisted, fitted with a piezoelectric ignition system for trouble-free starting, and feature a direct gas head assembly.
They feature a safety solenoid preventing the unit from leaking gas without first being electrically started. Supplied with an approved propane gas
regulator and hose. All models are tested and certified to CE/EN standards by DVGW. Manufactured to BS EN 416.

INSTALLATION
Note: If a small gas cylinder is used, the heater may not operate at maximum efficiency. It is recommended to use two or more cylinders
linked in parallel, to achieve maximum continuous efficiency (fig.1).
3.1.
Setting heater supply voltage.
3.1.1. Locate the voltage selection switch (fig.2.5).
3.1.2. If the correct supply voltage is not selected, remove the cover, select the required voltage position and refit the cover panel (fig.3).
3.2.
Connections.
3.2.1. Check heater and gas cylinder to ensure that they are both in good condition. If not, stop and contact your supplier immediately.
3.2.2. Site the heater and gas cylinder in the location to be heated.
3.2.3. Connect the heater to an electrical supply outlet, ensuring that the machine is correctly earthed. See Section 1 Safety Instructions.
3.2.4. Connect the gas supply hose to the excess flow valve, connect the valve to the pressure regulator, and connect the regulator to the
gas cylinder. Note: Left hand threads. Connect the other end of the supply hose to the heater. Ensure all connections are tight.
3.2.5. Gradually open the tap of the gas cylinder. Check hose and all fittings for any gas leaks.
WARNING! DO NOT USE A NAKED FLAME! To check for leaks, the use of a foamy soap solution is recommended.

OPERATION
IMPORTANT: To ensure continuous ventilation to the heater area, a ventilation opening must connect to the outside of the premises where the heater is to
operate. The opening must be 100cm
operating area.
4.1.
Switching Heater On.
4.1.1. Switch the On/Off switch to the ON (I) position (fig.4) and check that the fan starts running.
4.1.2. Push in the gas valve button and hold it in (fig.5), at the same time, press (repeatedly) on the Piezo Ignition Button (fig.6) until the flame
ignites. When the flame has ignited and the heater has started, keep the gas valve button pushed in for a further 10 seconds, then release it.
4.1.3. If the heater stops when the gas valve button is released, leave the fan on, wait for one minute, before repeating the ignition
sequence. Hold the gas valve button in for 15-20 seconds this time, before releasing.
4.1.4. The heat output is controlled by adjusting the gas pressure via the regulator. Turn the regulator knob anti-clockwise to reduce the
gas pressure and heat, and clockwise to increase the gas pressure and heat.
4.2.
Switching Heater Off.
4.2.1. 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.
fig.4
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.
