Notes

 

 

 

 

 

 

 

 

 

 

 

 

 

1)MST288 at 0.75 GPH firing rate utilizes a low fire baffle.

2)The increased stack temperature with the baffles removed is an approximation, based on a constant supply temperature of 212°F and 11.5% CO2. 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% CO2. Example: MST629 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.
