Model EZ-1/2/3 oil burners — Instruction manual
5. Adjustment and verication
Perform combustion test
COMBUSTION MUST BE VERIFIED WITH THE
(OPTIONAL) BURNER COVER IN PLACE —
 Removetheburnercoverifinstalled.Setupandadjustthe
burner using the following procedure. Replace the burner
cover,allowtheburner/appliancetorunatleast15minutes,
thencheckcombustionagain.Readjusttheburnerisneces-
sary. The CO
2
will increase when the cover is put on,
particularly if combustion air is piped to the burner.
If air is ducted to an (optional) air adapter,
combustion must be set based on the air inlet
temperature.Airtemperaturevariationswillchangehow
much air enters the burner, so the combustion must be set
to anticipate the variations. Follow the guidelines below.
Adjust burner using test instruments
1. Operateburnerf
or15minutesbeforemakingnaladjustmentsusing
test equipment.
2. Check for leaks in
fuel piping.
 Inspectfuelpipingsystemforleaks.Repairanyleakstoavoid
fire hazard from oil leakage or combustion problems due to
air infiltration into oil.
3. Inspectame
• Look at amethrough appliance combustion chamber observation
port.The ame should bewell-dened and should not impinge on
any appliance surface. (If you make air or gas pressure changes later,
inspecttheameagain.)
 Donotattempttoconrmcombustionsimplybyinspecting
theamevisually.Youmustusecombustiontestinstruments.
Failure to properly verify/adjust combustion could allow unsafe
operation of the burner, resulting in severe personal injury,
death or substantial property damage.
4. Inserttestprobeintoventorapplianceuedampersampleopening
tosampleueproducts.
 Heatingunitsdesignedfornaturaldraftoperationarenormally
set for a slightly negative pressure, usually –0.01 to –0.02
inchesw.c.draftatthecombustionchambertestport.Ap-
pliances designed for forced draft (positive pressure in the
chamber)mustbeair-tighttopreventexltrationofharmful
combustion products. Failure to properly set draft for the
appliance could result in severe personal injury or death.
5. Use combustion test equipment to verify that the burner is properly set
upforyourinstallation.Applianceswithpositivepressureinthechamber
mayrequireawiderairopening.Seeapplianceinstructionsfordetails.
Verify/adjust settings by testing with instruments.
• With the EZ burner equipped with the correct positioning bar, oil nozzle and
initialairbandsetting,theueproductswillusuallycontainbetween11½%
and12½%CO2(5.9%and3.8%O2)andzero(Bacharach)smoke.(Based

• Dependingonlengthofairpiping(whenused)andonairtemperature,CO

may change one per cent or more with the cover in place.
• Checksmoke.ItshouldbezeroontheBacharachscale.
• Settheapplianceuedamperorbarometricdraftregulatorsothedraft
or pressure in the vent complies with the appliance manufacturer’s
instructions.
Re-install (optional) burner cover and check
combustion again
1. Allowtheburnertooperatewiththecoveronforatleast15minutes.
(Insert a temperature probe to measure incoming combustion air tem-
