Honeywell APS just follow the tubes coming of the fan 
so where is it then cos i recently had fan changed and boiler serviced and there were no pipes coming from fan, flue or anywhere as far as i could see and just wondered if it uses a different method of proving
or do you not know either??

The manual i looked at was for a Swiftflow 75e, but ive got to admit that i always thought that they didnt have one (cant remember seeing one)
I've just checked up on the Hot Water express 80 which was the model before and no APS fitted.L & N to fan straight from board.

no a/p switch .relies on the fan .if it fails it baffels out and knocks the pilot out due to lack of air
