Condensate Drain; Mounting The Boiler - IDEAL HE24 Installation And Servicing

22 CONDENSATE DRAIN

Refer also to the British Gas document: 'Guidance Notes for
the Installation of Domestic Gas Condensing Boilers' (1989).
The condensate drain (provided in the h/ware pack) must be
connected from the boiler 'S' trap to a drainage point,
preferably within the building.
Ensure that the condensate trap is full of water before
commissioning the boiler . Refer to Frame 23.
The routing of the drain must be made to allow a minimum
fall of 1 in 20 away from the boiler, throughout its length.
The drainage pipework must be arranged so that obstruction
(e.g. through freezing) of external drainage pipe does not give
rise to spillage within the dwelling.
IMPORTANT.
If excessive external pipework cannot be avoided an
additional siphon kit and insulation are recommended to
prevent possible freezing.
All pipework and fittings in the condensate drain system
must be made of plastic. No other materials may be used.
The drain outlet on the boiler is standard 21.5mm overflow
pipe. This size must not be reduced in any part of its length.

23 MOUNTING THE BOILER

IMPORTANT.
Before mounting the boiler on the wall fit the 'S' trap hose moulding/
nut.
1. Ensure that the plastic plugs are removed from both the CH and
DHW pipes before mounting. N.B. Some spillage of water may
occur from the pipework when mounting the boiler to the frame.
2. Lift the boiler onto the wall mounting frame, locating it over the tabs
at the top of the frame.
3. Lower the boiler into position, engaging it onto the support bracket.
Note. Ensure the condensate drain pipe is correctly positioned
before continuing.
4. Using the fibre washers supplied in the hardware pack, engage and
then tighten the 4 water unions.
5. Engage and tighten the gas union, ensuring that the rubber seal is
in place. DO NOT overtighten.
6. Connect a pipe to the safety drain outlet using the nut and olive
supplied in the boiler hardware pack.
7. Plug the user control (display unit, pack A) into the control box. Refer
to Frame 66.
8. Screw the user control into position.
