Check that the combustion chamber is not damaged.
Check that the seal of the burner supporting plate and the relevant seal on the nozle are in good condition; if not,
replace them with seals having the same code.
When mounting back the burner (4) check the tightening of the bolts on the burner plate.
Note: All seals are asbestos-free and compliant with EC standards.
CLEANING THE FILTER ON AIR INLET
A dirty filter reduces the air flow, increases discharge temperature, reduces heat exchange and heater efficiency.
It is very important to clean the filter at regular intervals to guarantee the correct functioning of the machine.
The cleaning interval depends on the amount of dust in filtered air.
To clean it, proceed as follows:
Ø
Remove the filter from its seat
Ø
Shake it and leave the dust fall
Ø
Blow the filter with compressed air in counter-current
Ø
Place the filter back in its seat
the filter is an accessory to be ordered separately.
VENTILATING UNIT
Check
, at least once at the beginning of each season:
Ø
T
he proper alignment of pulleys and drive belts, if any, and check them for wear (if necessary, replace them with
belts of the same type and size)
Ø
The direction of rotation of the ventilating unit, indicated by the arrow on the fan (see fig 9)
Ø
The belt tensioning.
o
Grasp them: they must not be become loose by more than 2-3 cm (see fig 13).
o
To adjust tensioning, screw or unscrew the belt tightening bolt on the motor slide (13).
Ø
The motor absorption, in Ampere, must not exceed the value specified on Chapter
DATA SHEET
.
Ø
Check the tri-thermostat performance (see Chapter
TRI-THERMOSTAT
).
BURNER
For burner maintenance, comply with the instructions provided in the burner manual.
Check:
1. The gas pipe tightness
2. The tightness and condition of the chimney and connecting ducts or of the flue system/combustion air intake.
Combustion Analysis
1. At least once, at the beginning of each heating season, unless the current standards require shorter intervals, do a
combustion analysis carried out and recorded in the POWER PLANT HANDBOOK or PLANT HANDBOOK.
NOTE: Take note of all replaced components.
