Gas energy consumption in HEATING + DHW
Items 21, 22 and 23 are displayed alternatively with the gas energy consumption value expressed in millions, thousands and units
of kWh. e.g.: 21 / 033 / 145 / 827 corresponds to a gas energy consumption in HEATING of 33.145.827 kWh.
6. SWITCHING OFF THE BOILER
To turn off the boiler, disconnect the electric power supply using the two-pole switch. In the “Off” operating mode the boiler stays
off but the electrical circuits remain powered and the anti-freeze function remains active.
7. FILLING THE SYSTEM
Regularly check that the pressure displayed on pressure
gauge E is 1 - 1.5 bar, with the boiler cold. If the pressure is too
low, turn tap " B" to ll the boiler circuit (gure to side). Open
the tap very slowly in order to vent the air.
In case of overpressure, open drain valve "D".
In case of need of emptying the DHW storage boiler, open the
hose-connector valve " C".
A Disconnector
B Boiler/system lling tap
C DHW storage boiler drain tap
D Boiler/system drain tap
E Pressure gauge
Take special care when lling the heating system. In particular, open any thermostat valves in the system, ensure the water
enters slowly in order to prevent the formation of air inside the primary circuit until operating pressure is reached. Lastly,
vent any radiators in the system. CHAPPEE declines all liability for damage deriving from the presence of air bubbles in the
primary exchanger due to the incorrect or imprecise observance of the above.
The boiler is tted with a hydraulic pressure gauge which prevents the boiler from working if there is no water.
If pressure drops occur frequently, have the boiler checked by the AUTHORISED TECHNICAL SERVICE CENTRE.
8. ROUTINE MAINTENANCE INSTRUCTIONS
To keep the boiler efcient and safe, have it checked by the Authorised Service Centre at the end of every operating period.
Careful servicing ensures economical operation of the system.
