Flame Adjustment
1.
Start the heater, let it run for at least 15 minutes to reach operating temperature before
proceeding.
2.
Check the chimney draft, set the barometric damper to -0.05 WC when hot and
running.
3.
Check the atomizing air pressure, set the air filter/regulator on the heater:
XT-150/200 = 12-15 PSI
XT-250/300 = 15-18 PSI
4.
Ensure that the initial fuel pressure is set according to the table in Section 10 - Burner
Startup Procedure.
5.
When using the bypass regulator, adjust the thumb screw on the fuel bypass regulator.
Lock into position. The flame should extend no more than 3/4 of the way into the
chamber.

Mechanical equipment like gauges and
regulators are not always 100 percent accurate,
VISUAL INSPECTION OF THE FLAME IS REQUIRED
