Filling The System; Turning Off The Boiler; Gas Conversion - Baxi Fourtech Series Operating And Installation Instructions

WARNING
Disconnect the boiler from the mains power supply using the two-pole switch.
IMPORTANT:
Regularly check that the pressure displayed on the pressure gauge is 0.7 - 1.5 bar, with the boiler cold. In
case of overpressure, open the boiler drain tap. In case of insufficient temperature, open the boiler filling tap (figure 3).
Open the tap very slowly in order to vent the air.

The boiler is fitted with a hydraulic pressure gauge which prevents the boiler from working if there is no water.
N.B.:
In case pressure drops occur frequently, have the boiler checked by an authorised Service Engineer.
To switch off the boiler, disconnect the electric power supply.
In OFF mode (section 5) the boiler remains off (the display indicates OFF) but the electrical circuits remain live and the frost
protection device is enabled (section 9).
The boilers can operate both on natural gas and LPG.
All gas conversions must be made by an authorised Service Engineer.
