E. ADJUSTMENTS
1.
Adjust the purge timer, 1TR, for the required purge time (1/2 to 10 minutes).
IMPORTANT
Before igniting the burner, the dryer must be purged to remove possible
accumulation of combustible gases.
A minimum of four complete air changes
must be supplied.
Multiply the total system volume (dryer, baghouse and exhaust
ducts) in cubic feet by four. Divide this value by the burner air capacity in cubic feet
per minute. The result will be the required purge time in minutes
2.
Perform the fuel motor calibration procedure described in
Appendix A
.
Recalibrate annually or whenever a control motor is serviced or replaced.
3.
Verify that all low fire limit switch contacts are closed when the burner is at 0% and open
when the burner leaves low fire. Reference the burner operating instructions for switch

for purge (Eco-Star and StarJet conversion burners only).
