Commissioning the heating system

3.1

Starting up the heating system

Before switching on the power ensure that
– the operating boiler water pressure is sufficient,
– the fuel supply has been turned on at the main shut-off
valve, and
– the heating system emergency shutoff switch is in the
ON position.
3.2

Checking the operating pressure,

topping off the boiler water and
bleeding the system
The boiler water may loose a substantial amount of vol-
ume in the first few days due to the release of gas content.
This causes air pockets to form and make noise.
V With new heating systems, check the operating pres-
sure daily at first, topping off the boiler water and
bleeding the system as needed.
V Later on, check the operating pressure monthly, top-
ping off boiler water and bleed as needed.
3.2.1 Checking the operating pressure
Your heating contractor will have set the system to the
required operating pressure of at least 15 psi (1 bar) and
entered the setting in tab. 1, page 8.
V Read the current operating pressure and temperature
from the temperature/pressure gauge.
V If the temperature/pressure gauge needle drops below
the minimum pressure of 15 psi, the operating pressure
is too low. Add water to the system.
