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 (CO2 )or oxygen (O2 ) 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 (CO2) or oxygen (O2), 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 CO2 OR O2 READINGS.

3.CARBON DIOXIDE (CO2) OR OXYGEN (O2): Take a CO2 sample from the same location as the smoke sample. It is possible to achieve readings of up to 14% CO2 or 2% O2, but it is better to have a slightly lower CO2 with a zero smoke reading. To achieve a lower CO2 reading, open the air shutter on the burner until a zero smoke reading is obtained.
