Adjustment according to type of gas
Appliance works on natural gas (G20) or propane (G31). Adjustment of appliance for concrete gas type is
performed by producer, as it is given on the serial label. In case that it is necessary to use appliance with
another type of gas, than it is intended, it is necessary to ensure appropriate set for transformation. Then it
is necessary to make the following steps:
1. Remove covering
2. Open hermetic chamber
3.Hang down fixing clip
C
and pick gas pipe
A
out of the fan unit - Venturi.
4. Exchange nozzle
B
laid inside the gas pipe for nozzle from boiler transformation set.
5. Fix the gas pipe
A
back by clip and check, if the sealing is tight
6. Mount hermetic chamber and covering again.
7.Modify parameter related to the gas type:
switch boiler into the stand-by mode, hold DHW buttons pressed (pos. 1 and 2 - pic. 1 and 2) for 10
seconds: flickering „
PI01
“ is displayed
by pressing DHW button (pos. 1 - pic.1 and 2), set parameter
00
(by operation for natural gas) or
01
(by
operation for propane). Hold DHW button pressed (poz.1 - pic. 1 and 2) for 10 seconds. Boiler gets back
to stand-by mode.
8. Check inlet operation pressureat the gas valve inlet.
9. Use combustion analyser, connected to the exhaust outlet from boiler to check, if the CO2 content in
