Emergency measures

In the event of an emergency, e.g. a fire, proceed as
follows:
Close the main fuel shut-off valve.
Isolate the heating system from the mains power
supply using the heating system emergency stop
switch or the corresponding domestic fuse.
3.4 Checking the operating pressure, topping up with heating water and bleeding the
system
3.4.1 When should you check the operating
pressure?
Recently topped-up heating water loses much of its
volume in the first few days because it releases gases.
This causes air pockets, and the heating system will
start to rumble.
After installing a new heating system, check the
operating pressure daily for the first few days. If
necessary top up with heating water and bleed the
radiators.
After a while the operating pressure will only need to
be checked monthly. If necessary top up with heating
water and bleed the radiators.
We reserve the right to make any changes due to technical modifications.
