- Act on the two rear closing hinges to take out the cover.
- Take out the rear, front and side casing clamping screws.
We urge you to have authorised company fulfil
requirements regarding periodic maintenance
checks.
Since dust is extracted from the inside, the resistance on the 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.
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 the electrical and gas supplies making sure the valve is rmly
shut.
- Take out: all of the casings.
