Startup
Air Handler Pre Start Checks
•
Verify air handler has had proper start up and
airflow is at design maximum for heating cycle
(refer to air balance report).
•
Set bypass damper if provided in air handler.
• Airflow proving switch for main supply fan in
-
stalled and operational.
• Check with Control Technician: two-minute
post-purge programmed in air handler controller.
Upon call for air handler unit stop, burner cycles

later.
Burner Pre Start Checks
1. Open fuse disconnects before working on burner
(see Fig. 3-14).
Fig. 3-14 – OPEn FuSE diSCOnnECtS
2. Check all wire terminations for tightness.
3.
Check that the incoming voltage(s) are correct.
Compare measured voltages to burner motor and
ID motor nameplates and the “Burner Test Report”.
Reset fuse disconnects.
4. Check for correct rotation of 3 phase burner motor
and ID motor.
5. Verify that contractor has purged new gas lines of
air up to manual valve on gas train.
