Installing the appliance
1.
Unpack the appliance.
1.
Check the contents of the packaging. It consists of:
•
Appliance (A)
•
Fixing strip (B)
•
Condensate trap (C)
•
Installation instructions and operating instructions
•
Warranty card
•
Templates for either wall or jig mounting
2.
Check the appliance for possible damage: report damage immediately to the supplier.
3.
Decide either to use the fixing strip (supplied) or wall mounting jig.
4.
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.
5.
If the fixing strip is secured to the wall then slide the boiler down until latched.
6.
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 – Gas 22 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.
7.
Check whether the compression rings are sitting squarely in the mounting bracket
couplings.
8.
Fit the appliance, sliding it downwards on the jig. Ensure at the same time that the pipes
slide into the compression fittings.
9.
Tighten the compression fittings on the mounting bracket. Do not turn tightened valves on
pipes as this weakens joints within the boiler.
10.
Fit the flexible tube to the condensate trap outlet.
11.
Fill the condensate trap with water and slide it as far as possible upwards on to the
condensate drain connector below the appliance.
CAUTION
The Compact HRE 40 SB is only to be installed with the condensate
trap( length =235 mm) included in the boiler package.
When replacing the condensate trap make sure the correct version is
ordered (art.nr. 844787). Using an incorrect condensate trap can lead
to potentially unsafe situations.
12.
Connect the flexible tube from the condensate trap to the drain 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.
13.
Fit the flue in accordance with the instructions mentioned in § 8.4.4. Allow 15mm of white
tube externally to ensure the flue sealing ring is fitted correctly. No white part of the flue
should be visible externally once the black sealing ring is fitted correctly.
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.
