Hi,
I have an Ideal Logic Combi C30 boiler in my flat.
I am now vacating the flat, and so the boiler will not be used.
How should i switch it off?
Does it have a gas pilot flame in it that i must extinguish? Do you know how to do this?

In the consumer unit, there is a breaker for "Boiler". Presumably i should shut this off?
Also, the main appartment gas valve is under the consumer unit. Presumably i should turn it to "off"?

Turn the water off at the stop tap and leave the boiler on off on the front control panel or turn the room thermostat down to min

Could be vacant for 2 months....is it dangerous to turn anything off?...eg the gas flame might cause probelms if the electric is turned off.....ie nothing to control the gas flame?

As said above, just isolate the mains water and turn boiler to off on the front control panel.

Thanks very much indeed, and should i turn the gas off?...and also, turn the breaker off in the consumer unit?(the one with "boiler" written on it).
Is it ok to turn the water off to the whole flat?......wont that kind of mean something going wrong>...like you end up with the toilet water level going down and then get air bubbles in the water system...or something?

I wouldn't normally isolate the gas but it won't do any harm. The breaker can be left on though.
The water being off wouldn't effect the trap levels in the toilet etc. You may want to leave plugs in sinks etc though as the traps can dry out over long periods.

If you turn it off completely you will have no frost protection at the coldest time if year

Ok. Thanks get it. So ultimately, the tank would remove any doubt because with would have the capacity to cope. I think I'll challenge them.
