2.3.3 Fitting the heat exchanger
i
Check the position of the bottom section
again – It could have been moved while
performing the steps described above!
1. Remove the tension springs and bend the insulation
mat (1, Figure 06) on the bottom section towards the
boiler door.

2. Place the heat exchanger on the bottom section
(Figure 08).

Caution:
It weighs 85/104/143 kg!
- Use the lifting aids provided on the front and at
the bottom (2, Figure 07) and the flow and return
connections (2a) on the back to stabilise it.
- Take care that the seal (1a, Figure 06) is
NOT
displaced or damaged!

The heat exchanger must NOT be
suspended by the handles on the cover
(2b, Figure 07).
3. Remove the three thread protection caps (3, Figure 08)
from the connections between the bottom section and
the heat exchanger.

4. Fit each of the three corrugated pipe elbows
(see enclosed assembly instructions)
individually,
together with the seals, and bolt them in position
as follows:
- If necessary, loosen the union nuts on the heat
exchanger side in order to align the pipe elbow
precisely over the connection on the bottom section.
- Grease the thread with a lubricant.
-
Simultaneously fit the two union nuts by hand.
Insulate the three corrugated pipe elbows,
e.g. with AF/ Armaflex tape (Hoval Article
Number 2023 563; enclosed in the
«Control» package).
5.
Then fix the union nuts successively in position with high
expenditure of force
(using a pipe wrench without
extension; brace with an open-end wrench!)
.
6. Fix the heat exchanger in position on the bottom
section using the 8 collar nuts (M8).
