Inspections and 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 flue 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 (see parag. 3.24) and the
percentage of CO
2
(see parag. 3.24). If the measured load (with a correct
CO
2
level) is within 5% of the value indicated in parag. 3.24, the boiler
does not need to be cleaned.
The 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 off the electrical and gas supplies
making sure the valve is firmly
shut.
- Take out: all of the casings.
- Turn the required screw to lift the cover.
- Take out the two cover clamping screws.
- Act on the two rear closing hinges to take out the cover.
- Take out the rear, front and side casing clamping screws.
