• Open the boiler gas valve and check the static pressure to
the boiler at the measurement point (C) on the gas block.
C
The boiler has been factory tested for natural gas at 20 mbar.
The minimum gas inlet pressure is 17 mbar for natural gas
(see 2.4.3).

Measurement point c on the gas block
Check
• Check that the gas supply to the boiler is gas tight (in
compliance with the current regulations, see Chapter 7 the
maximum test pressure at the gas pipe inlet, with the boiler
gas valve open, is 60 mbar.
• Vent the gas pipe by unscrewing the measurement point (C)
on the gas block (tighten it again as soon as the pipe is fully
vented).
• Check that the gas connections in the boiler are sealed.
• Check that all electrical connections, including the earth
connection, have been made correctly.
• Check the electrical connections to the thermostat and other
external controls.
• Check that the flue-gas and air-supply connections are
sealed.
3. Switching the boiler on and setting the controls
• Replace the fuse in the spur and switch on the 230 V power
supply.
• Set the controls to heat demand.
• The boiler will begin an automatic venting-programme
(which lasts approx. 3 minutes) and will do this every time
the power supply is isolated.
• The boiler now starts to run. The operational status is shown
in the display. The normal operating status finally shows 0
in the display.

4. Checking/setting the gas/air ratio at full load
The Avanta Plus boilers are suitable for both natural gas and
propane firing. An optional propane-set is needed (see par.
2.4.2).
The boilers are supplied as standard set for natural gas
230 V
(G20), therefore the following procedure must be carried out
BEFORE the boilers are fired and commissioned for the first
time on propane:
- Fit propane set (instruction in kit);
- adjust the fan speed (for procedure; see Par. 2.9.8, for values;
see table 06 and table 08) and;
- adjust the gas/air ratio (for values; see table 06 and table
08).
