8 Gas, Water & Boiler Connection
8.1 Systems Connection
The water and gas isolation valve connections are on the jig.
The condense drain and safety discharges connections are
not on the jig but their pipe runs are shown on the template.
Assemble the copper tails and washers to the jig, secure,
then plumb the system as shown in diagram 8.1. taking into
account the need to plumb the condense and safety valves
also.
NOTE: Do not subject isolation valves to heat.
Slacken the test point screw, see diagram 8.1, connect a
manometer.
The whole of the gas installation, including the meter, should
be inspected, tested for tightness and purged in accordance
with the current issue of BS6891 and in IE the current edition
of I.S.813 “Domestic Gas Installations”.
Remove the manometer and secure the test point screw.
On completion of system connections and as an aid to
installation, slacken the jig securing screws, this will allow
a greater tolerance of site conditions when connecting the
isolation valves to the boiler.

IMPORTANT: With regards to the Health and Safety
Manual Handling requirements, two persons shall be required
to lift the appliance. It should be noted that the appliance is
made up of two modules each module requiring two persons
to lift.
8.2 Tank Module Connection
IMPORTANT:
The electrical cables to the boiler and the
immersion heater need to be routed before the installation of
the tank module.
Remove the tank module top polystyrene packing, then the
carton sleeve.
Pull the tank module front panel forward off the retaining clips.
Slide the tank module into position over the jig and align with
the isolation valves.
NOTE: If there is restricted clearance where the boiler is
to be located, the tank and boiler modules can be assembled
before sliding into position over the jig.
Position the plastic sealing washers as shown in diagram 8.3
and connect the isolation valves. The pipe retaining bracket
can be slackened to ease connection.
