I'm firing my recently built (from odds and ends) cross-draft kiln.
I have two of ward's burners the 750s. Three hours into a glaze fire
I'm at 1200 f. l'm at about 1 pound of pressure. burners 1/2 open.
air just cracked. flame is fairly blue. if I open the air more I get
a disconcerting sucking noise. Do I need the valve open more to add
more air to avoid the sucking noise? How many pounds of pressure
will I go up to?
Thanks,
Eric in Oceanside
