4.4 REASSEMBLY
Once the combustion calibration adjustments are properly set, the unit can be reassembled for
service operation.
1. Set the Controller’s Enable/Disable switch to the Disable position.
2. Disconnect AC power from the unit.
3. Shut off the gas supply to the unit.
4. Remove the manometer and barbed fittings and reinstall the NPT plug using a suitable pipe
thread compound.
5. Remove the combustion analyzer probe from the 1/8” (3.18 mm) vent hole in the exhaust
manifold. Replace the 1/8” NPT plug in the manifold.
6. Replace the unit’s side panels and front door.
4.5 TEMPERATURE CONTROL CALIBRATION
Carefully follow the procedures below to properly set up the temperature control for the unit.
Ignoring this commissioning step may cause water temperature faults, poor water temperature
control, and rapid cycling of the unit.
The unit normally comes factory set and calibrated for a 130°F (54.4°C) setpoint (default value).
However, if a different setpoint temperature is desired, it can be changed using the procedure in
Section 4.6.1. Temperature control calibration should be performed each time the setpoint is
changed.
There are two primary adjustments for performing temperature calibration: Min Load Adj and
Max Load Adj (minimum and maximum load adjustment). Adjustments to these settings are
made at minimum and maximum load conditions and should be made in small increments, from 1
to 3 degrees F (0.55 to 1.65 degrees C). After making an adjustment, the outlet water
