hi guys profile 50 lpg boiler moved and changed from horizontal to vertical flue..... now the aps wont switch???? seems to be more of a restriction on the air intake of vertical flue, this is a flange on end of flue pipe???
any ideas???

 

[tommytoker]

how long is vert flue? how many bends? 45's or 90's? is the flue equiv length within manufac spec? lazy, worn out fan?
disturbed and broken aps when moving boiler (its a b1tch but **** happens) can you make aps when blowing/sucking gently?
do you here a click? dont trust it, check spades with beep test c to n/o
does the flange get removed if flue longer than x? have you got manufac instns with the boiler/flue.?

Don't really think there's a need to swear

aps will make and boiler will fire by blowing tubes.... max flue lenght 1.8m according to mfis... flue is vertical to terminal no bends
