USER - SYSTEM MANAGER
Have
r
’s Technical Assistance Service start-up your
g
boiler for the first time. Once this has been done, the
boiler can be left to function automatically. Under certain circumstances, such as after long periods of disuse, the ser-
vice engineer responsible for the boiler may need to re-start it without involving the Technical Assistance Service. To do
so, perform the following checks and operations:
- Check that the gas cock and heating water cock are
open
- While the system is still cold, check that working pres-
sure in the heating circuit is
over 1 bar
but below the
maximum limit specified for the boiler. If this is not the
case, contact
r
’s Technical Assistance Service.
- Set the room thermostat to the required temperature
(~20 °C) or, if the system has a timer, make sure that
this is switched “On” and adjusted to the required tem-
perature (~20 °C).
- Turn the system's main power switch ON
- Adjust the boiler and storage cylinder thermostats (
NK
models) to about the middle of the section with three
lines
