Draft settings for a Burnham V908A w/Beckett CF1400
Hey Wallies, have a new customer clean out tomorrow with the above mentioned set up. I downloaded both the boiler manual and the Beckett manual, but neither one tells me what number to set draft.
The boiler manual says check the burner manual, the burner manual says check the boiler manual. I have all the other settings-head, low/high air band, low/high pump pressure, nozzle, etc., just not draft. The only thing the Beckett manual states is "...typically +.01 at the breech".
I'm expecting to spend alot of time with this as the owner mentioned a number of other people took a crack at it, which to me means, wrong nozzle, wrong air settings, wrong draft.
If anyone has any insight I'd greatly appreciate it.
Edit: Giving the boiler manual another read I missed the first table, which looks like .35wc pressure in firebox and +.10 at the breech, which seems high. I'll probably give US Boiler a call tomorrow
