Connection of Supplies
1.
Extend the gas supply to a point convenient to the heater and connect to the solenoid valve at the
bottom left hand side of the heater. A union and gas tap must be incorporated to facilitate
maintenance. The inlet to the valve is 8mm nut & olive.
Note that the valve must be supported when the union is fitted.
2.
Purge the system and test for gas soundness.
3
Provide an electrical supply socket, or fused spur nearby. Make sure that the live and neutral poles
are correctly phased. If phasing is reversed, the heater will not operate correctly.
A plug is already wired into the mains lead. If the mains lead is too long remove the plug and cut the
wire to length then follow the instructions below for rewiring the plug.
4.
Free the mains cable from the heater. One end is already attached to the heater and has a mains
cable clamp fitted. Slacken the nut on the cable clamp, slide it in the slot in the support plate at the
bottom right hand side of the backplate and re-tighten the nut. The wires in the cable are coloured in
accordance with the following code:-
Green/yellow
-
Earth
Blue
-
Neutral
Brown
-
Live
If these colours do not correspond with the colours identifying the terminals of the plug which is being fitted,
proceed as follows:-
Connect the wire which is coloured green/yellow to the terminal marked with the letter E or by the Earth
Symbol or colour green.
Connect the wire which is coloured blue to the terminal marked with the letter N or coloured black.
Connect the wire which is coloured brown to the terminal which is marked with the letter L or coloured red.
If the plug is unmarked, or if in any doubt, consult a qualified electrician.
Two pin plugs must not be used.
If a fuse is fitted, it must have a 3 amp rating. See Fig. 4.
