3/1 3/1 2/2 5/3
NOTE: The above settings are approximations based upon clean equipment in proper working order. Combustion air
adjustments will vary with location, altitude and type of fuel used.
WARNING: LACK OF COMBUSTION AIR CAN CAUSE A DIRTY FIRE, ODOURS IN ENCLOSED
SPACES, AND BACKDRAFTING, POTENTIALLY RESULTING IN NAUSEA OR ASPHYXIATION OF
THE OCCUPANTS.
ALL AIR ADJUSTMENTS MUST BE DONE BY A QUALIFIED SERVICE TECHNICIAN
BECKETT CF375
COMBUSTION AIR ADJUSTMENTS
For proper combustion air adjustment a calibrated
gas analyzer and smoke tester should be used to
ensure complete combustion. Air adjustment should
be made at the correct input and be adjusted to
achieve 5% Oxygen and 12% CO2. For optimum
combustion efficiency the combustion air control
should be set to provide no more than No. 1 smoke
(Bacharach Scale). The Beckett burner has a
calibrated air band, which will assist in adjusting the
primary air for a good oil/air mixture. Adjust the air
band supply by loosening lock screws and moving air
shutter and if necessary the bulk air band. Begin by
reducing the air until the unit begins to produce
smoke. Increase air until no smoke is produced.
Check for excessive heat build up in the heat
exchanger. Insufficient air will cause flame
impingement and reduced heat exchanger life.
Increase air until heat build up has been eliminated.
Check for proper ignition. Once satisfied re-tighten all
screws and locking mechanisms.
This adjustment is to be carried out while the unit is operating and after 5 minutes of firing. Rotating the air bands on
the burner housing makes the adjustment.
SETTING OIL FIRING RATES
1.) Choose BTU required. For example 313,600
2.) Check name plate for recommended pump pressure. 120psi is recommended.
3.) Check nameplate for recommended air setting. A 3/1 air setting is recommended.
4.) Install a pressure gauge in pump gauge port and start the burner. Operate for 5 minutes until blower fan
starts.
5.) Adjust pump pressure to 120 PSI.
6.) Adjust air band to 1 and adjust air shutter to 3.
