FUNCTION
Checks during and after commissioning
After commissioning, ensure that the
FASTECH
boiler runs the start-up
and subsequent shutdown procedure correctly using the:
- function selector
- calibration of the heating water temperature selector and DHW
temperature selector
- required room temperature (adjusting the room thermostat or timer).
Check operation in DHW mode by opening a hot water tap with the
function selector set to Summer mode and to Winter mode.
Check that the boiler stops completely when turning the main system
switch to “OFF”.
Operate the appliance continuously for a few minutes by turning the
main switch to “ON”, setting the function selector to Summer and
keeping the DHW utility tap on. The processing binders and residue
evaporate and the following can be checked:
- supply gas pressure
- combustion.

pressure is between the minimum and the nominal supply values
as specified in the multigas table
- turn off the hot water tap
- disconnect the pressure gauge and tighten the pressure tapping
point upstream of the gas valve.
