Operating instructions

START-UP PROCEDURE

LIGHTING

Before starting the unit, check the following:

- The water pressure on the pressure gauge “O”;

- That the gas cock and the inlet for domestic water are

open.

These models are equipped with electronic ignition which utilises contact

ionisation.

To make the boiler operational, simply press the On/Off switch

“L”.

The green L.E.D. “I” will then turn on.

At this point the boiler is ready for use, a centralised

electronic control unit will automatically light the main

burner when needed. If the burner does not light within

the pre-set safety time limit, the red

“B” L.E.D. will light

up. To reset the ignition system, the reset button

“A”

must be pressed. Should the system fail to light a

second time, check to make sure that the gas cock is

open. If the problem persists, contact one of our

Authorised Service Centres for assistance.

WINTER AND SUMMER OPERATING MODES

The boiler is fitted with a selector knob “C” which

allows you to switch between winter <>and

summer <>operating modes and vice versa.

When the knob is set to <>, the boiler can

serve the dual purpose of providing heat and/or hot

water for domestic use.

The supply of hot water for domestic use always

takes precedence over heating. When the knob is

set to <>,the boiler cuts out the heating system and only provides hot

water for domestic use (when needed).
