METEO GREEN HE R.S.I.
- Reassemble the mixer with the flap in a horizontal position and the spacer
springs placed at 120° as shown in the (Fig. 1.18)
- Reassemble gas ramp and silencer, working vice versa.
- Check the number of times the fan turns
- Switch on the power to the boiler and turn on gas cock again
- Fill in and stick on the accompanying transformation data label
- Close the air box cover
- Close up the instrument panel again
- Reassemble the casing and panel
Programme the "Gas type" parameter and regulate the boiler following the
instructions in the "Adjustments" section.
Transformation must be done by qualified personnel only.
After completing transformation, regulate the boiler again following
instructions given in the specific paragraph and apply the new identi-
fication label from the kit.
GENERAL MAINTENANCE
Be particularly careful when handling the mixer: the Clapet juts out from the
body so that the mixer must be laid on the air inlet side (flap area) or make
sure the Clapet is inside the body if it has to be laid on the Clapet side.
The Clapet must never have to bear the weight of the mixer.
Clean the Venturi from any dust with an aspirator during the annual system
cleaning. Check that flap and Clapet are working correctly (all open at rated
flow, all closed at minimum flow).
25 - CHECKING COMBUSTION PARAMETERS
Do as follows to analyze combustion:
- Go to GAUGING & SERVICE and set the combustion analysis password
as given in paragraph "Adjustments"
- Insert the analyzer probe into the specific openings on the air box, after
removing screw B and cap C.
The fumes analysis probe must be introduced as far as possible.
- Screw the analyzer setscrews into the fumes analysis opening.
- The first display gives the reading of the number of turns corresponding to
maximum heating power set on the boiler (see paragraph "Adjustments"
item P23)
After turning the domestic hot water temperature selector again the boiler
will ignite to check combustion.
- Check combustion.
- Refer to the "Adjustments" paragraph if the boiler has to be gauged.
- Remove the analyzer gauge and close the combustion analysis openings
by their screws.
IMPORTANT
The function switching off the boiler when the water temperature reaches
maximum limit of about 90°C will also stay on during combustion analy-
sis.
26 - MAINTENANCE
- The appliance must be systematically controlled at regular intervals to
make sure it works correctly and efficiently and conforms to legislative
provisions in force.
- The frequency of controls depends on the conditions of installation and
usage, it being anyhow necessary to have a complete check carried out
by authorized personnel from the Servicing Centre every year.
- Check and compare the boiler's performance with the relative specifica-
tions. Any cause of visible deterioration must be immediately identified
and eliminated.
- Closely inspect the boiler for signs of damages or deterioration, particularly
with the drainage and aspiration system and electrical apparatus.
- Check and adjust - where necessary – all the burner's parameters.
- Check and adjust - where necessary – the system's pressure.
- Analyze combustion. Compare results with the product's specification.
Any loss in performance must be identified and corrected by finding and
eliminating the cause.
- Make sure the main heat exchanger is clean and free of any residuals
or obstruction.
- Check and clean - where necessary - the condensation tray to make sure
it works properly.
IMPORTANT - Always switch off the power to the appliance and close the
gas by the gas cock on the boiler before carrying out any maintenance and
cleaning jobs on the boiler.
Do not clean the appliance or any latter part with flammable substances
(e.g. petrol, alcohol, etc.).
Do not clean panelling, enamelled and plastic parts with paint solvents.
Panels must be cleaned with ordinary soap and water only.
