1. Remove the sealing caps from the boiler connections.
NOTE: A small amount of water may drain from the boiler
once the caps are removed.
Sealing Washers
2. Lift the boiler as indicated by the shaded areas. The boiler
should be lifted by TWO PEOPLE. Engage the mounting
bracket at the top rear of the boiler on the wall plate (Fig. 21)
(see Safe Manual Handling page 5).
3. Insert the sealing washers between the valves and pipes on
the wall plate and the boiler connections.
4. Tighten all the connections.
9.4
1. Remove the discharge pipe from the kit and determine the
routing of the discharge pipe in the vicinity of the boiler. Make
up as much of the pipework as is practical, including the
discharge pipe supplied.
IMPORTANT: Make all soldered joints before connecting
to the pressure relief valve. The relief valve is intentionally
angled to the right of the boiler. DO NOT adjust the
position of the valve. The discharge pipe must be installed
before pressurising the system.
3. The pipework must be at least 15mm diameter and run
continuously downwards to a discharge point outside the
building. See section 6.7 for further details.
4. Utilising one of the sealing washers, connect the discharge
pipe to the adaptor and tighten the nut hand tight, plus 1/4
turn to seal.
5. Complete the discharge pipework and route it to the
outside discharge point.
9.5
1. Using the short piece of rubber hose supplied, connect the
condensate drain pipework to the boiler condensate trap
outlet pipe. When connecting the hose, ensure that the
condensate sump is not inadvertently unscrewed.
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" & HHIC recommendations).
2. The hose will accept 21.5mm (
which should generally discharge internally into the household
drainage system. If this is not possible, discharge into an outside
drain is acceptable.
3. The boiler condensate trap should be primed by pouring
approximately 300ml of water into the flue spigot. Do not
