Barometric draft regulator
When a barometric draft regulator is
used, adjust the barometric draft
regulator such that the over-fire draft is
0.00 to +0.01 “w.c., while the breech
draft is approximately -0.02 “w.c.
During operation of the burner, the
barometric draft regulator installed in
the vent system must move freely.
