8.4 Fitting The Boiler
(Fig. 24)
1. Remove the tape from the tap rail on the support
bracket and fit the central heating return filter (Fig. 26).
2. Lift the boiler over the support bracket using the lifting
points shown in Fig. 24 and engage onto the top hooks (see
Lifting paragraph page 4).
NOTE: When installing in Loft/Small Compartment
access for lifting the boiler from the front can be
gained for two people using the lifting points (Fig. 24).
3. To gain access to the connections between boiler and
valves, release the facia securing screws (
1
/
4
turn) and hinge
down the facia panel.
4. Make the gas connection first. This will centralise the
boiler. The gas sealing washer is an integral part of the gas
tap.
5. Insert the fibre sealing washers between the valve outlet
face and the flange on the copper bends of the water circuit
connections.
6. Tighten the connections.
8.5 Making the Condensate Drain Connection
(see section 7.6)
1. Connect the condensate drain using the 1” BSP nut and
seal supplied.
Ensure the discharge of condensate complies with any
national or local regulations in force (see British Gas
“Guidance Notes for the Installation of Domestic Gas
Condensing Boilers”.
2. The condensate outlet terminates in a 1” BSP nut and
seal for the connection of 21.5mm (
3
/
4
in) plastic overflow
pipe which should generally discharge internally into the
household drainage system. If this is not possible, discharge
into an outside drain is acceptable.
NOTE: To ensure the correct operation and integrity
of the condensate drainage system - Carefully pour
approximately 1 cupful (250ml) of water into the flue
products exhaust, at the top of the heat exchanger
(Fig. 25) to ensure a seal is made in the trap.
