Appropriate greetings.
My grandfather has a combi boiler in the bathroom, it was installed a year or two ago. It is in a cupboard. A 'man' came around to measure something which needed access to the flu (presumably exhaust?) - the 'man' was from the company who makes the boiler and it cost nothing, but he commented that he couldn't do the measuring job due to access restrictions. By all accounts, he will return. I have been volunteered to make sure that there is appropriate access for the second coming.
What is 'appropriate access'? I don't think that being in a cupboard in itself is a bad thing - they are put in cupboards in kitchens, no? As I have yet to properly investigate this wonder, can anyone tell me what I should be looking for? (No points awarded for 'The Boiler').
Solemn declaration of thanks.
