1. Using a suitable lifting device, lift the appliance on its base
packaging. Offer the appliance up to the wall plate and engage
the bottom edge of the back of the appliance on to the wall
plate (Figs. 27 & 28). Ensure that there is adequate clearance
for the lifting equipment (see Section 7.2).
2. Push the appliance back onto the wall plate and engage the
securing nuts at the top of the appliance by sliding to the right
and swinging down (Figs. 28 & 29).
3. Tighten the two securing nuts on the wall plate and
complete the securing of the appliance by replacing the two
screws previously removed. (Figs. 29 & 30).
4. Remove the base packaging.
9.3
1. Connect the central heating circuit to the top of the
appliance using 22 mm compression fittings to avoid heat
damage to the case and seals; the return is on the left and the
flow is on the right.
NOTE: To assist with the purging of air from the system
pour water into the flow and return connections to displace
the air in the heat exchangers.
2. Connect the gas to the bottom right of the appliance using
the 15 mm gas cock provided (in the top of the packaging).
Remove the bottom cover and lower the control tray (See
Section 10.1 paragraph 3 and Figs. 40 and 41).
Install with the test nipple to the left (see Fig. 11) this allows
the connection to the appliance to be tightness tested
independently of the gas pipework up to the appliance which
then can be tested using the test nipple on the gas meter.
It may be difficult to reassemble the bottom panel if this is not
done.
3. Note: Care must be taken to ensure that the over current
switch is not disturbed from its correct position (See Fig. 2a
when replacing the bottom cover). The switch should be up at
the back - the '1' should be depressed.
9.4
1. Connect the condensate drain to the trap outlet pipe.
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 connection will accept 21.5mm (

pipe which should generally discharge internally into the
household drainage system. If this is not possible, discharge into
an outside drain is acceptable.
3. The condensate trap should be primed by pouring
approximately 300ml of water into the flue spigot. Do not
allow any water to fall into the air inlet.
