RESETTING THE BOILER
If boiler locks-out (see fig. 2 page I), indicator no.9 ON) proceed as follows:
wait approximately 3 minutes from the last shut down
set Main Switch (1) to OFF position (see fig.1 page I)
set Main Switch (1) either to summer or winter position (see fig. 1 page I). The boiler comes into operation.
If lock-outing persists, turn the boiler OFF and call an authorised service engineer.
WARNINGS FOR THE USER
To keep the boiler in efficient and safe operating condition, carefully follow the instructions listed below:
Have normal maintenance performed at least once a year by one of our authorised service centres (a fee will be charged),
combustion tests are necessary every two years and should again be carried out by a qualified technician authorized by the
manufacturer (in accordance with D.P.R. 412 regulations, 26-08-93).
Periodically check system pressure on the pressure gauge and check that pressure is between 0.5 - 1.5 bar with the system
cold.
Do not clean the casing or internal parts of the boiler with thinners or solvents. Cleaning should always be done using only
soap and water and be carried out by authorised personnel.
Never leave flammable materials in the immediate vicinity of the boiler.
For greater comfort and more rational use of heat, it is advisable to install a room thermostat connected to a clock timer to
turn the boiler on and off during the course of the day or week with two temperature levels (in accordance with D.P.R. 412
regulations, 26-08-93).
The boiler is equipped with an anti-freeze system, which comes into operation when the temperature reaches 5°C (heating
sensor) and 4°C (hot water sensor), protecting the boiler down to a temperature of -2°C. To protect the internal heating unit
as well, fit a room thermostat or a remote control.
Please ensure you have a fully completed BENCHMARK BOOKLET and this is kept with your installation instructions.
