Installing the appliance
1.
Unpack the appliance.
2.
Check the contents of the packaging. It consists of:
•
Appliance (A)
•
Wall mounting strip (B)
•
Condensate trap (C)
•
Installation instructions
•
Operating instructions
•
Warranty card
•
Templates for either wall or jig mounting
3.
Check the appliance for possible damage: report damage immediately to the
supplier.
4.
Decide either to use the wall mounting strip (supplied) or wall mounting jig.
5.
The templates show the positions for the horizontal flue. Drill the exit holes,
being sure to prevent dust or debris from entering the boiler or pipe-work.
6.
If the wall mounting strip is secured to the wall then slide the boiler down until
latched.
7.
If the jig is fixed securely to the wall then it is possible to fit the pipe
connections prior to hanging the boiler. Pipe connections are (from right to
left) as follows for both methods: PRV 15 mm – CH flow 22mm – DHW 15
mm – Gas 22 mm – Cold main 15 mm – Return 22 mm.
IMPORTANT: The gas supply should be minimum 22mm up to gas isolation
valve on boiler
. It is the installers responsibility to ensure sufficient gas supply.
8.
Check whether the compression rings are sitting squarely in the mounting
bracket couplings.
9.
Fit the appliance, sliding it downwards on the jig. Ensure at the same time
that the pipes slide into the compression fittings.
10.
Tighten the compression fittings on the mounting bracket. Do not turn
tightened valves on pipes as this weakens joints within the boiler.
11.
Fit the flexible tube (D) to the condensate trap outlet (C).
12.
Fill the condensate trap with water and slide it as far as possible upwards on
to the condensate drain connector below the appliance.
13.
Connect the flexible tube from the condensate trap to the drain (E) via an
open connection. The condensate discharge system must be made of
plastic, no other materials may be used. The discharge duct must have a
minimum gradient of 5 – 20 mm/m. Condensate discharge via the gutter is
not allowed given the risk of frost and the possible damage to materials.
14.
Fit the flue.
CAUTION
Always fill the condensate trap with water and place
it on the boiler before powering up the boiler.
Not placing or filling up the condensate trap may
cause flue gases to come into the installation room
and can lead to dangerous situations!
In order to place the condensate trap the front cover
must be pulled forward or removed entirely.
Note
It is recommended that any external condensate pipe is insulated and increased to
32mm diameter in order to prevent the condensate from freezing.
7.4.1
Fitting the cover plate (optional)
Hang the flanged upper edge of the cover plate on the washers under the base of the
appliance and slide the cover plate as far as possible towards the rear.
