Notes (2)
The increased stack temperature with the baffles removed is an approximation, based on a constant supply temperature of 180°F and 11.5% CO

. Actual field conditions may be different.
(3)
These values are minimum and could be as much as -.03" w.c., more without impacting performance. Pressures based on 11.5% CO

. Example: MPO-IQ231 could have a breech pressure of
-.03" w.c. and an overfire pressure of .020" w.c. 4) Single stage fuel pump is standard, two-stage fuel pump is optional. Burner manufacturer has preset single stage fuel pump to settings shown in table above. Two-stage fuel pump is factory set at 140 PSI and must be readjusted to settings shown above during burner start-up.
