5-2.1 Service Access
Boilers have a quick release front panel enabling all routine servicing to be carried out
without the necessity of removing any other panels.
The heat exchanger and condensing unit both have bolt on covers which give access for
servicing.
Note
Before removing side panels study the burner position and the Boiler wall position and decide on the best
oil pipe configuration, see Section 6.
5-2.2 Heating Connection
The flow and return connections are on the top of Boiler heat exchanger - Ø22mm copper.
IMPORTANT
The FLOW connection is on the LEFT HAND side, the RETURN connection is
on the RIGHT HAND side when facing the Boiler from the front - see fig. 5-
2b.
5-2.3 Condensate Drain
The condensate drain arrangement for Internal Wall Mounted Boilers are the same as for
Floor Standing Boilers see 4-3. However there is room for the condensate trap to be
located within the Boiler casing if required.
5-2.4 Fixing the Boiler - Suggested Procedure
1. The first step is to give full consideration to:-
i Flue and flue terminal position.
ii Condensate drain arrangement.
iii Oil pipe arrangement.
iv Heating system pipe runs.
2. Remove carton, save this to protect the work top if applicable.
3. Remove the pull-off front panel.
4. Study the burner position and the Boiler wall position and decide on the best oil pipe
configuration, see Section 5-2.6 and Section 6.
5. Refer to section 4-3 and decide on the most suitable condensate drain arrangement.
6. Remove the pull-off top panel.
7. Unscrew and remove both side panels and bottom panel complete with control box
bracket.
8. Remove burner complete with control box.
9. Remove expansion vessel by disconnecting pipe (BWISC or BFISC 12/16 only).
10. Remove access door and lift out the three baffles from heat exchanger.
11. Remove Boiler body from wood transport blocks - 4 screws.
12. Offer back panel to the position required on the wall and use this as a template to
mark the drilling positions for both mounting rawl bolts ‘R’ fig 5-2c.
Holes R1 are used to secure the boiler to the transport pallet, these can also be used
for additional fixings to secure the back panel to the wall, but should never be used as
load bearing fixings.
13. Remove panel and accurately drill required holes and fit 2 rawl bolts into holes ‘R’,
and set rawl bolts securely in the wall using nuts.
14. Remove knockout ‘K’ from back panel if required.
15. Hang back panel onto rawl bolts and mark the positions of any holes required through
wall for oil pipes, fire check valve, electric cable or condensate drain pipe.
