3.6.2 — Initial Fuel-Curve Point Adjustments
Notes:
•
You must be password entered to make changes to curve point values.
•
The gas and air set values presented in this instruction are for example only.
•
Air-fan speed is adjusted with the (VSD / F & A) buttons.
•
Gas-valve actuator position is adjusted with the (A) button.
•
Confirm curve-point emissions are within expected ranges per emission table 3.3 in section 3.6

Although the burner was fire tested at the factory, be certain to check fuel valve actuator coupling for tightness before
making any adjustments to fuel or air. Be certain the valve is fully closed when the control indicates “0” degrees open.
• The installer is responsible to ensure that safe fuel-to-air ratios are being maintained.
• If an AZL (+) or (-) button is held continuously when adjusting an actuator position value, the value will change at a
progressively faster rate.
• When increasing a setting, increase air and follow with fuel.
• When decreasing a setting, lower fuel first and then air.
Rapid temperature changes to the heat exchanger can cause major damage due to thermal shock.
It is imperative when starting a cold vessel for the first time the vessel be warmed slowly, either by allowing the burner
to cycle for intermittent periods or leaving at low fire. This should be done until the vessel is up to normal operating con-
ditions.
