At my local real ale pub, the landlord has had fitted overhead shelters, with open sides, so the smokers can have somewhere to go to have a ciggy and it also allows walkers and dog owners to sit outside with their drinks. However, he has created a problem for himself. The boiler that supplies the hot water and CH has its flue under the top of the shelter and as a consequence, the condensation is hitting the shelter and dripping down on anyone sat underneath. I think someone else mentioned that anyone sat there would be in contact with the carbon monoxide that comes out of the flue.
Can the flue be extended, by a handyman, without running into any problems.
