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 a 1/2, gas supply cock immediately upstream of the gas
control thermostat 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.
External wiring to the water heater(s) must be installed in
accordance with current I.E.E. Regulations for the wiring of
buildings and to any Local Regulations that may apply.
The Auto Ignition Heater is designed to operate from a
220/240V, Single Phase supply. The fuse rating is 5 amps.
The method of connection to the mains electricity supply should
facilitate complete electrical isolation of the appliance, preferably
by use of an unswitched shuttered socket outlet in conjunction
with a fused three pin plug, both complying with the
requirements of BS 1363.
Alternatively, a fused double pole switch or fused spur box
serving only the heater may be used.
The point of connection to the mains electricity supply should be
readily accessible and adjacent to the appliance.
Connect the electrical supply to the main control panel terminal
block via the cable glands in the base of the control panel.
Mains input cable should be 0.75mm
connected to the mains supply as detailed above.
It is recommended that screen cable is used where the volt-free
contacts are to be connected from an external supply. This will
eliminate the risk of possible interference from nearby high
voltage cables.
