2.10 SET BURNER FOR EFFICIENT OPERATION
SET END CONE Use turbulator settings in section 5.0 BURNER SPECIFICATIONS and
operating decal as a guide to set turbulator, particularly for nozzle
changes.
PUMP PRESSURE 150 psi.
AIR SETTING Use air settings in section 5.0 BURNER SPECIFICATIONS and
operating decal as a guide to set air damper.
SAMPLING HOLE A sampling hole is required for the burner setup. Drill a 3/8” diameter
hole on top of the vent pipe and use the supplied test port plug to seal
after burner setup.
BURNER SETTING Set the burner to give a stable symmetrical flame. After 15 minutes of
normal operation, check SMOKE for #0 - trace reading and measure
CO
2
.
Readjust the burner controls as required.
EFFICIENCY Always leave burner set with CO
2
reading about 1% of CO
2
lower than
the peak efficiency achieved with a #0 - trace smoke (e.g. a #0 – 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.
ANALYZER Use an electronic gas analyzer for setup and record information on the
furnace setup decal. Failure to do so may void warranty. Always set
flame with proper draft, smoke and CO
2
measurements.
NOTE: Some electronic gas analyzers do not account for recovery
of latent heat and give low efficiency readings. Use the table
below to determine the AFUE.

2.11 HUMIDIFIER
If a humidifier is installed ensure that no water can drip or run from it into the furnace. This
would cause deterioration and void the furnace warranty. Maintain humidifier regularly as
required by the humidifier manufacturer.
