Gas Connection:
NOTE: ALL GAS FITTING MUST ONLY BE CARRIED OUT BY AN AUTHORISED PERSON.
1. The appliances do not require an electrical connection, as they function totally on the gas
supply only.
2. It is essential that the gas supply is correct for the appliance to be installed and that adequate
supply pressure and volume are available. The following checks should therefore be made
before installation:
a. Gas Type required for the appliance is shown in the rating label. Check that this is
correct for the gas supply the appliance is being installed for. The gas conversion
procedure is detailed in this manual.
b. Supply Pressure required for this appliance is shown in the ‘Gas supply requirements’
section of this manual. Check the gas supply to ensure adequate supply pressure
exists.
c. Input Rate of this appliance is stated on the Rating label .The input rate should be
checked against the available gas supply line capacity. Particular note should be taken
if the appliance is being added to an existing installation.
NOTE: It is important that adequately sized piping runs directly to the connection joint on the
appliance with as few tees and elbows as possible to give maximum supply volume.
NOTE: Ensure the regulator is converted to the correct gas type that the appliance will operate on.
The regulator outlet pressure is fixed ex-factory for the gas type .
3. Correctly locate the appliance into its final operating position and using a spirit level, adjust
the legs so that the unit is level and at the correct height.
4. Connect the gas supply to the appliance through the regulator. A suitable jointing compound
which resists the breakdown action of propane must be used on every gas line connection,
unless compression fittings are used.
5. Check all gas connections for leakages.
6. Check that the gas operating pressure.
7. Turn off the mains gas supply and bleed the gas out of the appliance gas lines.
