2.9 SET BURNER FOR EFFICIENT OPERATION
SET END CONE
Use turbulator settings in section
3.0 BURNER SPECIFICATIONS
and
operating decal as a guide to set turbulator, particularly for nozzle
changes.
PUMP PRESSURE
Refer to section
3.0 BURNER SPECIFICATIONS
or operating decal.
AIR SETTING
Use air settings in section
3.0 BURNER SPECIFICATIONS
and
operating decal as a guide to set air damper.
SAMPLING HOLE
On smoke/vent pipe, between appliance breech and draft control,
punch or drill a 1/4” round opening. Direct Vents have a sampling port
located on the breech connecting adaptor.
DRAFT PRESSURE
Using an accurate draft meter; adjust the draft control to obtain -0.04”
wc draft pressure at the breech sampling hole. Use two barometric
dampers if necessary. Not applicable to Direct Vent.
BURNER SETTING
Set the burner to give a stable symmetrical flame. After 15 minutes of
normal operation, check SMOKE for zero trace reading and measure
CO
2
. Readjust the burner controls as required. When the burner is
set, lock the adjustments with the locking nuts.
EFFICIENCY
Always leave burner set with CO
2
reading about 1% lower than the
peak CO
2
efficiency achieved with a zero to trace smoke (e.g. a zero to
trace reading of 12.5% CO
2
should be set back 1% to 11.5%). This
gives better allowance for fuel and draft variations and maintains a
better seasonal efficiency. When the burner is set, lock the
adjustments with the locking nuts.
FLAME CHECK
Look through view port to check the flame after setting the burner. If
the flame is not clean and symmetrical, reset the burner or replace the
nozzle.
DO NOT
START BURNER UNTIL ALL FITTINGS AND COVERS ARE IN PLACE.
2.10 CLASSIC AIR BLOWER SETTING
Ensure power is off when adjusting blower setting
. For heating, use the blower speeds
shown on the furnace specifications to give a rise of 70 – 85°F. The #4 Lo blower speed can
be used for air circulation when neither heating nor cooling are required. Set blower speeds to
match the installation requirements.
