Notes
(2)
The increased stack temperature with the bafes removed is an approximation, based on a constant supply temperature of 180°F and 11.5% CO
2
. Actual eld
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
2
. Example: MPO-IQ231
could have a breech pressure of -.03" w.c. and an overre 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.
