Boiler wall flue advice

[Monochrome24]

We are having problems with our gas powered boiler. I know it's old but we are on the breadline as are most of us and replacement is a luxury!
My wife discovered that the socket circuit kept tripping and by searching I found that the boiler was causing it. On closer inspection there was water in the (removable) base and this has been caused by rain being blown in through the flue from outside!

My question is, knowing the hazards with CO, can I attached a wall mounted deflector/shield over the flue to stop the rain coming in?

The boiler is attached to same wall as flue so distance is the thickness of wall plus about 5 inches outside. Flue is a round tapered metal shape with flutes - about 3 inches diameter.

I've found many roof types online but can't see any for walls unless the cooker hood types are ok.


Thanks in advance!

Not allowed!

See why water is coming in.

Why did you not mention the make and model of boiler?

Thanks for replying!

Why is it not allowed since the flue can still vent out - just want to shade it from rain. Vertical flues get covers...
We moved in to this house about 8 years back and this Spring the wife chopped back a huge bush in front of the flue - since then rain blows in when in the 'wrong' direction! I assume the bush sheltered the adverse weather...

Flue is roughly horizontal.

I'll try and take some pics and add to album asap.

Thanks again.

Because to ensure safety, the gas regulations prevent anyone from doing their own modifications to gas appliances.

The manufacturers design and test the appliance and accept legal liability for its safety and so it cannot be modified.
