5.6 Connecting the Gas and Water
5.6.1 Figs. 10 and 16 show the locations of the
fittings.
5.6.2 Do not over tighten nuts and use another
spanner to apply counter force to avoid
damaging the appliance
5.6.3 Gas Supply
Connecting the gas supply.
Connect a 15mm gas pipe to the gas service
tap and tighten the union nut securing the tap
to the appliance.
5.6.4 Central Heating
Connect the central heating pipework (22mm
o.d) to the respective valves, right hand =
return, left hand = flow, and tighten the
nuts.
5.6.5 Hot Water
Provide a suitable coupling and connect the
hot water draw-off pipe to the 15mm o.d tail.
Tighten the nut.
If the hot water system does not include a tap
below the hot water outlet connection provide
a suitable drain tap to permit draining of the
appliance hot water side during servicing.
5.6.6 Cold Water
Connect a 15mm cold water service pipe to
the inlet stopcock of the appliance. Tighten
the nut.
If the cold water supply is liable to large
pressure fluctuations, a flow/pressure
regulator should be fitted in the supply pipe.
5.6.7 Safety Valve Discharge
The safety valve is located beneath the
pump. Connect discharge pipe to the 15mm
o.d. tail (using a compression fitting).
When connecting, ensure the discharge
pipe does not restrict access to or operation
of the central heating return valve. The
discharge should terminate facing down-
wards exterior to the building in a position
where discharging (possible boiling) water
will not create danger or nuisance; but in an
easily visible position.
5.7 Electrical Connections
5.7.1 The electricity supply must be as specified
in clause 4.7. If controls external to the

N.B. IT IS ESSENTIAL THAT ALL EXTER-
NAL CONTROL CIRCUITS AND WIRING IS
WIRED FROM THE SAME ELECTRICAL
ISOLATOR AS SERVES THE APPLIANCE.

Remove finger guard by releasing four
securing screws (fig 18a), hinge down the
control fascia. (fig. 19a) until it rests in an
approximately horizontal position.
Remove electrical cover by releasing four
securing screws.
The mains input terminal block is the left
hand block located on the front control facia
(see fig. 19a).
5.7.3 The electricity supply cable from the isolator
and the appliance terminal block must be 3
core flexible sized 0.75mm² (24 x 0.2mm) to
