Hi folks.

I have an indoor Grant Euroflame kero boiler. The burner is now a Riello 40.

There are two holes from the boiler through the wall to the outside. One I can see is an exhaust outlet but what is the other one for. If it has no function anymore can it be blocked up as cold air blows in there.

Just thinking now it may have been connected by a Flexi tube to the original grant burner years ago..but not sure.

Q: can that hole be closed up.

Thanks..

a few photos would help

most likely fitted with a balanced flue originally

Which means there might not be adequate room ventilation for it if you close that up. As Jim says, a few pics.

BTW Make sure you have a working (they have a limited life span) CO monitor/alarm in the same room as the boiler. Also very important to have all boilers serviced annually, but even more so with internal one.

The exhaust side on the left.. on the right is a hole which leads back in to the top of the boiler..

I wonder do the fumes just blow back in there if the wind is blowing in that direction

Any further ideas on this ?

Without eyes on the installation it is too dangerous a prospect to give advice on. The potential dangers of giving wrong advice is too great.

I advise getting your regular service tech to advise you. It will be the safest option.

That's a balanced flue chimney, which makes the boiler very safe and only uses outside air, keeping room warm with boiler been sealed from room.

Unfortunately, you got the wrong replacement burner type, you should have got a Riello RDB burner.

Thanks for reply..

Any ideas on how to solve this problem...

When the wind blows in the direction of the flue I sometimes get the smell of the fumes in that room....Is there something I can get to move the fumes away quicker.

Note: burner runs really smoothly and there is no visual sign of fumes/ exhaust. I have a monitor in that room.

Thanks..
