All installations and services must be performed by qualified service personnel.

G. INITIAL BURNER OPERATION:
IMPORTANT: READ BURNER INSTRUCTION MANUAL (INCLUDED WITH BURNER) BEFORE
CONTINUING.
To successfully service and initially set up the oil furnace, you must use the following instruments:
A. A smoke tester
B. A carbon dioxide
()
2
CO or oxygen
()
2
O analyzer
C. A flue gas temperature measuring device
D. A draft gauge. Scale should read from (+) .10" WC to (-) .25" WC
E. A volt/OHM/milliamp multimeter
F. An oil pressure gauge capable of reading 0-150 lbs./sq. inch
Turn the main service switch, which provides power to the furnace, to the "OFF" position. Set the thermostat above room
temperature, open all valves in the oil line, and be sure the oil tank is filled. Open the inspection cover on the upper mounting
plate above the burner. Turn on the main service switch, and prime the pump according to the pump manufacturer's
recommendations.
NOTE:
Pump pressures for Beckett burners are 100 PSIG (AF burners) on all units, except the OL2, OC2 and OH2 (AFG
burners) which are 120 PSIG.
Pump pressures for Riello burners range between 145 PSIG and 170 PSIG.
?CAUTION: DO NOT RUN THE PUMP DRY FOR MORE THAN FIVE MINUTES, AS
IRREPAIRABLE DAMAGE MAY RESULT.
When ignition is established, make a preliminary burner air adjustment to attain a clean combustion flame. Replace the
inspection cover above the burner. After the furnace is warmed up to a steady state condition (about 15 minutes), the final
burner adjustment should be made using combustion instrumentation for measuring draft, smoke, carbon dioxide (CO
2
) or
oxygen (O
2
), and stack temperature. In order to achieve the most efficient combustion possible, the following steps must be
taken:
1. DRAFT: Draft readings should be taken both at the overfire air tap and in the flue connection to the chimney.
The overfire draft reading obtained should be a negative (-) .01" to (-) .02" WC and the flue draft reading should be a negative
(-) .02" to (-) .04" WC. The overfire draft reading takes precedence over the flue draft reading when adjusting the barometric
draft control.
2. SMOKE: A smoke sample should be drawn from the same opening used to check the flue draft. If the first flue smoke
reading is "O", close the air shutter on the burner until a trace smoke reading is obtained.
IMPORTANT: TO ACHIEVE PROPER COMBUSTION AND THE EFFICIENCIES LISTED IN SALES
BROCHURES, INSTRUMENTS MUST BE USED TO SECURE CO
2
OR O
2
READINGS.
3. CARBON DIOXIDE (CO
2
) OR OXYGEN (O
2
): Take a CO
2
sample from the same location as the smoke sample. It is
possible to achieve readings of up to 14% CO
2
or 2% O
2
, but it is better to have a slightly lower CO
2
with a zero smoke
reading. To achieve a lower CO
2
reading, open the air shutter on the burner until a zero smoke reading is obtained.
