While the oil burner is adjusted at the factory, it is re-
commended that the operating characteristics of the
burner be determined at start-up and readjusted if
necessary. Run the unit long enough at the burner
maximum firing rate to make sure the burner has
reached a stable maximum operating temperature.
THEN, check the burner and adjust as follows:

Check to determine that the smoke spot number
does not exceed 0.5 with a Bacharach control. Ad-
just the burner as required to achieve this maximum.

Check to determine that the CO2 rate is from 12 - 13
percent and that there is no CO production. Adjust
the burner as required to achieve this operating cha-
racteristic.

Measure the temperature of the flue gas exiting the
unit to determine that it does not exceed 250 de-
grees F (120 C).

Combustion inspection can be carried out on the
unit through the hole (item N) provided in the inspec-
tion port (item 7). Be sure to replace the washer
(item M) and the test point screw (item 6) properly
after inspection.

At the time of start-up, check the safety and control
devices as follows :

- Thermostats :

• Check to see that the thermostat bulbs are

correctly positioned in their housings. This is
essential to provide temperature sensing to
facilitate burner shut-down in the event of
overheating,

- Flame monitoring :

• Check to make sure that the burner shuts

down properly upon the deactivation or discon-
nection of the flame monitoring device or inter-
ruption of the flow of fuel,

- Safety Pressure Relief valve :

• Check the safety pressure relief valve in the

heating circuit for proper operation.
