THE APPLIANCE MUST ONLY BE USED WITH NATURAL
GAS.
The installation of the gas supply should conform to the
requirements of IM/16 published by British Gas p.l.c. or BS
6891. Jointing compound used must conform to BS 5292 pt 5.
Caution
Do not apply heat in close proximity to the gas control as
this will result in damage occurring to the control.
Fit the 1⁄2 m/f elbow into the gas control valve. Fit the 1⁄2 gas
supply cock immediately upstream of the gas control and elbow
and connect to the gas supply. Pressure test the gas installation
for soundness. If any doubt exists as to size of gas supply pipe,
consult your local Gas Region.
It is recommended that a pressure test point is fitted on the input
next to the gas supply valve.
The method of connection to the mains electricity supply should
facilitate complete electrical isolation of the appliance preferably
by use of an unswitched fused spur.
Alternatively, a fused double pole switch or fused spur box,
serving only the heater, may be used. A 3mm separation is
required between each pole.
The point of connection to the mains should be readily
accessible and adjacent to the appliance.
Wiring external to the water heater must be installed in
accordance with the I.E.E. Regulations for the wiring of buildings
and to any local regulations that may apply.
The Heater is designed to run off a permanent 220/240V 1 Ph
50 Hz supply and the fuse rating is 3 Amp.
