Installing the boiler
Mounting the boiler
When mounting the boiler, proceed in
accordance with design documentation
conditions (e.g. wall load-bearing
properties, chimney inlet, pipe inlet and
outlet connections). The boiler is designed
for mounting on a non-combustible wall. If
the boiler is to be installed on a wall which
is not non-combustible, the wall must be
panelled with fi re-resistant and thermally
non-conductive material. When installing
the boiler, applicable fi re safety regulations
must be abided by. The actual installation
is done as follows (Fig. 12):
Mounting procedure (Fig. 12):
1. Take the paper template provided (M)
and attach it to the place of installation
(W), for instance with a sticky tape. When
positioning the template, use a plumb
bob or spirit level.
2.
Using the indicated points on the
template, drill the holes required
(mounting bar or connection ramp).
Important:
If you are using a connection
ramp (R) – not part of standard delivery
– boiler connection end pieces (T) must
not be used.
3.
If the combustion gases fl
ue is to
penetrate through the building’s
peripheral wall, set out an opening for
the concentric tubing penetration (O).
4. Remove the paper template (M).
5.
Drill the required holes of diameters
indicated on the template.
6. Insert wall plugs into the holes for the
mounting bar (L), and fasten the bar with
the screws provided.
7. Mount the boiler (K) on the mounting bar
(L).
8.
Install adapter (A) to the boiler and
tubing for combustion gases exhaust
(O). Fill the space between the tubing
and the wall with non-combustible
material.
9.
Remove plastic plugs from boiler
outlets.
10. Install the sealing ring, fl ow restrictor and
protective fi lter on hot water inlet into the
boiler (S).
11. Install boiler connection end pieces (T).
Please note:
When connection ramp (R)
is not to be used.
12. Install a protective fi lter (not part of
delivery) in the heating water inlet.
13.
Install isolation valves (not part of
delivery) on all outlets from the boiler.
14. Connect heating water and hot water
and gas pipes to isolation valves.
15. Install the heating system water top-up
valve lever (P).
16. Fill up the boiler (see page 10).
17. Check all joints and connections for
leaks.
Installing boiler with connection
ramp
1. If you are going to use the connection
ramp, proceed according to points 1 – 6
in the previous chapter “Mounting the
boiler”.
2. Assemble the connection ramp (R) as
shown in the ramp installation
instructions.
3. Fasten the connection ramp (R) to the
wall using the wall plugs and screws
provided.
4.
Install a protective fi lter (not part of
delivery) downstream the heating water
inlet isolation valve.
Please note:
Install another shutting
valve (not part of delivery) downstream
the protective fi lter, to make maintenance
easier.
5.
Connect gas, heating water and hot
water pipes.
6. Remove plastic plugs and safety clips
from all shutting valves and dismount the
