Draining down boiler?

[Mgrant]

I have a pressure gauage to swap on a boiler, Its not in the combustion chamber .

Would anyone drain the boiler by closing the valves on the flow and return, as I no these can be prone to leaking once turn. How would you drain the boiler if not? Just remove pressure from the system at a drain ?

As I said I am not going in to the combustion chamber is a alpha he 25. The combustion chamber is a different sealed off chamber after you remove the cover. Have replaced the direct hot water flow switch on these before.

I am a plumber thought I could do stuff on the wet side of a boiler as long as didn't go into the chamber. Electricians fault find etc.

Well… you either go by the book or not.

Sorry James. You can not work on any gas appliance whether it be on the gas side or water side unless you are Gas Safe registered. Cover your backside mate. Either get registered or leave them alone. Have a gander at the Gas Safety Installation & Use regulations.

It's a bad job if you think you can work on the wet side inside a gas boiler!!!

if you have to take they cover/case off you cant sorry

 

[Mgrant]

Sorry, I thought you could as the removing the cover doesn't expose the combustion chamber this has its own cover. Not like a lot of modern boilers were the external cover is the cover to the combustion chamber too.

What do you think about this? From your boiler book:
