5 Boiler Installation
5.1 Unpacking
Open the carton, check the items supplied against the boiler
pack contents list on the carton flap.
5.2 Boiler Preparation
With the boiler still in the bottom tray, remove the casing front
cover. Open the controls cover first, then by undoing the two
screws at the bottom and the one at the top, lift the front cover
off, see diagram 5.1.
Place front cover in a safe place on one side until required.
Remove boiler.
From the fittings pack, slide a tubing nut and washer on to the
return and flow tail pipes which are supplied with the boiler, see
diagram 5.2.
Connect the return and flow tail pipes to the boiler, see diagram
5.2.
Fit suitable compression fittings to the tail pipes.
For pipework entering the boiler from below, an optional flow
and return pipe incorporating an air vent is available, kit No.
2000458585, see diagram 5.3.
NOTE: If the installer wishes to adapt the standard pipework he
may do so, but must incorporate an air-vent at the highest point
on the flow pipe and the highest point of the return pipe, see
diagram 5.11.
5.3 Mounting the Boiler
Ensure to fit the blanking plate and gasket on the boiler flue
outlet not being utilised, see diagram 5.6.
If the rear flue outlet is to be utilised for the installation of the flue,
it will be necessary to connect the flue spigot and gasket to the
outlet using self-tap screws provided, see diagram 5.6.
NOTE: The spigot would only be fitted to the top flue outlet
where a vertical flue kit or in certain flue bend orientations is
incorporated. Instructions are supplied with these kits.
Lift the boiler into position, hooking over the top mounting
bracket.
NOTE: Anti-theft screw kits are available, part no’s: 458113 and
458114.
IMPORTANT: Secure lower bracket to wall with screw into
wall plug already prepared.
NOTE: It will be necessary to move the control box to access the
bracket by slackening its retaining screw and swinging it out on
its hinge, see diagram 5.10.
Where the boiler is located in a restricted place, see diagram 1.3
in Instructions for Use, it may be necessary to remove the
control knob to enable the control box to be fully swung out.
If the top flue outlet is to be utilised, secure the top turret and
gasket or flue spigot and gasket depending on desired flue
orientation in position with the 2 taptite and 2 self-tap screws
provided, see diagram 5.9.
NOTE: Ensure that the taptite and self-tap screws are positioned
as shown in diagram 5.8 to enable the air deflector to be fitted
correctly.
If fixing to the back of the boiler, i.e. spigot, slide the flue into the
spigot until it engages in the bayonet connection and then twist
clockwise to lock, see diagram 4.1.
Make sure the fitting of the flue to the boiler is correct.
The fan assembly may also be removed or slid forward about
halfway out of the boiler, to ease access.
Disconnect the blue and purple electrical connections to the
fan, and the air pressure switch tube connections, see diagram
5.5.
NOTE: Remove the electrical connections by pulling insulation
boots only.
Remove the securing screw at the front, see diagram 5.5.
The fan assembly may now be slid forward.
