Restart the primary air blower.
 Shut off the secondary air blower. Continuity should disappear between terminals 13 and
14 immediately, but should remain between terminals 14 and 16 for several seconds as the
secondary air blower coasts to a stop.
ATOMIZING AIR LIMITS (EcoStar II or MegaStar with primary air blower for Oil or LP fired
systems only)
 Start the primary air blower only.
 Set the multi-meter to read continuity and verify that continuity exist between the following
control panel terminals:
□ 17B and 17C
□ 17C and 17D
 Shut off the primary air blower. Continuity should disappear between terminals 17B and
17C immediately, but should remain between terminals 17C and 17D for several seconds as
the primary air blower coasts to a stop.
 Note: For StarJet burners without compressed air atomization and for EcoStar burners (not
EcoStar II or MegaStar), a jumper wire should be installed in the burner junction box
between terminals 17B and 17D.
ATOMIZING AIR PRESSURE (EcoStar II, MegaStar, or StarJet with compressed air
atomization for Oil or LP fired systems only)
 Shut off the exhaust fan and combustion air blower.
 Set the multi-meter to read continuity and verify that continuity exist between control panel
terminals 17B and 17D
 Note: For compressed air atomization a jumper wire should be installed in the burner
junction box between terminals 17C and 17D.
 Shut off the manual valve on the compressed air supply line then carefully loosen the pipe
plug downstream of the compressed air flow meter to bleed off any residual air pressure.
 Verify that continuity does not exist between control panel terminals 17B and 17D.
 Re-tighten the pipe plug and open the manual valve on the compressed air supply line.
EXHAUST FAN LIMITS: FLOW SWITCH & MOTOR STARTER INTERLOCK
 Start the exhaust fan only. Set the multi-meter for AC voltage and verify that 120Vac is
present between the following control panel terminals:
□ 12 and L2
□ 13 and L2
 Shut off the exhaust fan. 120Vac should disappear from terminal 13 immediately, but
should remain on terminal 12 for several seconds as the exhaust fan coasts to a stop.
LOW GAS PRESSURE (Gas-fired systems only)
 Move the FUEL SELECTOR switch to the GAS position and place the temperature control
loop in manual at 0% output.
 Start all equipment required for burner operation, and then momentarily press the RESET
button on the control panel. After the purge sequence is completed press START to
establish the pilot and low fire gas flame.
