5.2 SET BURNER FOR EFFICIENT OPERATION
BURNER SETTING
Use burner settings in the table on page 20-21 or operating decal as a
starting guide to set the burner, particularly for nozzle changes.
Those
settings are only starting points for the adjustments and are not
meant as final settings.
On Beckett AFG burner, make sure the correct retention head and static
disk are installed on the burner for the desired firing rate. The head is held
in place by two screws at the end of the burner blast tube. From the burner
technical information table on page 20-21, the head model
is always after the AFG designation and the static disk size after the head
model information. For example, the AFG F0 3-3/8’’ means an AFG chassis
burner with a F0 head and a static disk of 3-3/8’’.
PUMP PRESSURE
Refer to the table on pages 20-21 or operating decal.
AIR SETTING
Use air settings on pages 20-21 as a guide to set air
adjustment.
Those settings are only starting points for the
adjustments and are not meant as final settings.
DRAFT REGULATOR
The draft regulator should be installed at least 3 flue pipe diameters from
the breech of the furnace.
SAMPLING HOLE
On smoke/vent pipe, drill a 3/8” round sampling hole. The sampling hole
should be at least 1 flue pipe diameters away from the draft regulator,
between the breech and the draft regulator of the furnace.
