Turn the blower service switch or remote
control device to ON. The (optional) intake
or discharge damper motor will start to
open. Once the damper is 90% open the
damper motor internal end switch will close
and energize the blower motor starter.
Check that the motor amp draw is less than
the FLA (full load amps) of the blower
motor.
The fan RPM may need to be reduced
to decrease motor amps.
Opening the driver (motor) pulley
decreases RPM and motor amps.
Closing the driver pulley increases
RPM and motor amps.
Record the motor amps on the Start-
Up Sheet.
If the RPM was adjusted in the field use a
tachometer to record the new RPM on the
Start-Up Sheet.
Check the belt tension after any RPM
adjustments. See the belt tension detail.
Check the air flow pressure drop.
The air flow switch on single speed units is a low air flow switch only and opens below 0.15 in w.c.
The target pressure drop range for the single speed unit is 0.40 – 0.50 in w.c.
Do not adjust airflow switches
Use the profile plates or blower RPM to increase or decrease the pressure drop.
Record the pressure drop on the Start-Up Sheet.
Close the burner gas shut off valve
This will allow the unit to fire the pilot only and will be opened at a later time
Set the Burner Intake On Off Switch is set above the outside air temperature
Turn the burner service switch or remote control to ON
The Fireye Flame Safety Control energizes the ignition transformer and pilot gas valve
After the pilot flame is established, the main gas valves will open
At this time the pilot will be the only flame in the burner
The pilot regulator should be adjusted so the pilot flame signal is stable 6-18 VDC
