3.5.23  Set and check operation of low Oil Pressure Switch.  Set at approximately 80% of low fire oil pressure.  

Check visually, or test electrically to confirm that circuit opens at the proper oil pressure. 

3.5.24  Check Atomizing Air Switch.  Set just below the minimum operating pressure during pre-purge.  Check 

visually, or test electrically to confirm that circuit opens on a loss of atomizing air pressure.  

3.5.25  Check Blower Combustion Air Flow Switch.

Shut burner power off. 
Disconnect both wires at the air flow switch and temporarily clip them together.  Make sure that they 
cannot ground against anything, since they will be powered with 110 volts during the test.  

Put a continuity meter across the common and normally open terminals on the air switch. 

Disconnect the wire to the main automatic oil valve. 
Start the blower motor.  The meter should read electrical continuity as soon as the blower starts.  
Disconnect the wire which energizes the coil of the motor relay (starter) or open the main power 
disconnect switch to the burner. Within 3 to 4 seconds after the blower motor is de-energized, the 
meter should indicate an open air flow switch circuit (no continuity). 
If  the switch does not open in 3 to 4 seconds, readjust accordingly.   Turn the air flow  switch 
adjustment screw clockwise to shorten cut-off response time and counter-clockwise to lengthen cut-off 
response time

8) 

Turn the burner power off.  Remove the shorting clip from the two disconnected wires and cap them with 

a wire nut, let them hang loose (they will be powered with 110 volts, so don’t let them ground out).

Reconnect the wire to the main automatic oil valve.  Turn the burner on.  With the air flow switch wires 
disconnected, the burner should go into a purge cycle, but neither the ignition nor the main fuel valve 
circuits will be energized.  If  they do energize, there is a wiring problem. Correct as required. 
Turn power off.  Reconnect the air flow switch wires to the air flow switch terminals.  Place burner back 
into normal operation. 

3.5.26  Check all burner and heat exchanger controls and operating devices. 

3.5.27  The  Owner’s  Operating  Instructions,  at  the  end  of  this  manual,  should  be  posted  in  a  clearly  visible 

location close to the burner. 

3.5.28  If  the  burner  operation  is  abnormal,  refer  to  Section  5,  Troubleshooting,  as  well  as  troubleshooting 

information  in  the  flame  safeguard  manufacturer’s  bulletin  shipped  with  the  burner.    It  is  also  strongly 
suggested  that  all  test  procedures  outlined  in  the  flame  safeguard  control  manufacturer’s  bulletin  be 
conducted. 

3.5.29  Complete the Burner Start-Up Information and Test Data sheets on pages 33, 34 and 35.

4.1.1  The UCM is equipped with an Induced Flue Gas Recirculation (IFGR) system which must be operational 

during burner operation. The IFGR utilizes the flue gas to lower the overall NO

X

 emissions to comply with 

the NO

X

 emission regulations. 

4.1.2  This system has been successfully proven in field applications on firetube applications. Testing and field 

operations have been performed using natural gas and light oil.
