Gigs, I am referring to checking gas contents incoming into the chamber that could be contaminated by exhaust fumes due to failed seal or dislocated inner tube
Doing FGA checks on such boilers is left to person dealing with the boiler. The boiler does not have a test point, so makers are not expecting you to FGA the exhaust (attended a call where over zealous 'engineer' disconnected a boiler and rcomnded replacement- boiler was reinstated after Gas Saf got involved)
Laura, high CO reading means there is insufficient oxygen available for combustion process. A service may be all that is required. Cannot see the reasoning for new boiler based on FGA analysis alone
