I have quoted THAT to my CORGI inspectors tony
I have also SHOWN that to my CORGI inspectors!!
I did not say screw down the window I said Make the Window permanently unopenable
which I have done with a drill, a screw or two, some filler and a hacksaw blade. so as the screws are not accesable by the home owner
it just says openable window in the regs, it doesnt say a screwed down window doesnt constitute a permanently closed window.
In some cases you can remove the openable window and repace it with one that dont, in the case of PVC this may be the only option, but it still can work out cheaper than moving the boiler from the desired location.
on the point you made about anglian coming back and reopening a window, well we cannot be held responsible for what other people do after we have left
I have installed many open flued boilers in my time to find a conservatory whacked on the back of the house right over the lovely air vent I installed.
We can only insure that the installation conforms to GSI&UR while we are there, or are you saying that we must return periodically to ensure the home owner has cocked up our lovely work?
I have edit this a few times as I dont want to get anything wrong and anger agile
If you can show me that I am wrong agile I will of course change my working proceedure, but I have been through this question many times with many installers, building inspectors and CORGI inspectors so am quite happy that I am right and am not contravening the regs in anyway.
by the way please dont think that I am being atagonistic with my post, I have great respect for your knowledge and would appreciate any crictism you have.
