OPERATING INSTRUCTIONS
INSTRUCTIONS TO OBTAIN PROPER OPERATION OF
BOILER-BURNER UNIT
A ¼" diameter slot
is provided in the inspection cover plate to
take draft readings in the combustion cham
-
ber.
(Figure #14)
A ¼" diameter hole will be
required in the flue pipe between the boiler
and barometric damper (if used) to take
draft, CO

, smoke and temperature read
-
ings. Adjust air shutter on oil burner to obtain
a “trace” of smoke. Measure CO
2
at
this point. Increase air adjustment to
lower CO
2
approximately one percent.
Check to insure minimum negative
.02 w.c., (water column), “overfire”
draft and zero smoke. If -.02 w.c.
“overfire” draft can not be maintained,
changes and/or modifications may be
required in the vent
-
ing or the chimney.
The following tables
are provided as a
guideline for ini-
tial start-up. Final
adjustments MUST
be made using
combustion instru
-
ments as previously
mentioned.
IMPORTANT: Check safety control circuit after burner adjustments have been made for satisfactory performance.

NoTES:
(1) Model 6225 needs a head setting of 1 and 7275 needs a head setting of 2.
(2) Nozzle sizes with an h designation are hago brand, all others are Delavan.
(3) Information in above table uses Beckett model AFG burner for model numbers 365-5200 and
Beckett model CF375 for model numbers 6225 and 7275.
Pressure Control - Remove cover and note pressure
A.
setting. With boiler operating, decrease the setting.
When the setting is lower than boiler pressure, the
control will open and turn off the boiler. After checking
pressure control, reset control to original setting.
Mechanical Low Water Cut-off - May be checked by
B.
opening the blow-off valve on the lower portion of the
cut-off body while the boiler is running. This will drain
the water from the boiler and break the circuit to the
burner.
!
WARNING
WATER WILL BE BOILING HOT.
