maintenance
We urge you to have authorised company fulfil
requirements regarding periodic maintenance
checks
.
Since dust is extracted from the inside, the resistance on the
fl
ue side,
through the boiler, will increase, leading to a decrease in the heat load
(and, consequentially, in the power).
Prior to cleaning, check the heat load and the percentage of CO
2
(see
Par. 3.13). If the measured load (with a correct CO
2
level) is within 5%
of the value indicated, the boiler does not need to be cleaned.
Th
e operation must therefore be limited to cleaning the trap.
ATTENTION!
A drop in the heat load can be caused by an obstruction
in the exhaust channel or air intake pipe. First of all
make sure that this is not the cause.
If there is a drop in the heat load greater than 5%, check
how clean the burner condensate-collection pan is. Also
clean the trap.
First phase – Disassembly.
- Shut o
ff
the electrical and gas supplies
making sure the valve is firmly
shut.
- Remove all of the casings.
- Act on the two closing hinges to take out the cover.
- Take out the rear casing clamping screw on the right an
d left side
.
- Take out the side clamping screws (righ
t/left side).
- Take out the closing plate clamping screws
(fl
ue exhaust output side)
and take o
ff t
he casing.
