Connecting Multimeter to Measure Flame Strength
1.
Refer to Figure 4-3 and remove the right side panel from the unit to access the flame
detector.
2.
Disconnect the flame detector wire lead #135 from the detector and connect the multimeter
in series with the wire lead using alligator clips as shown in Figure 4-3.
3.
Ensure that the multimeter is set to the µA scale.
4.
Ensure that the multimeter is set to the µA scale.

4.2.5 Recommendations for Temperature Calibration
Carefully follow the procedures of section
4.4 Temperature Control Calibration
, below, to
properly set up the temperature control for the heater. Ignoring this commissioning step may
cause water temperature faults, poor water temperature control, and rapid cycling of the heater.
4.2.6 Recommendations for WHM (Water Heater Management) Operation
In case of multiple Innovation units, it is highly recommended to
ALWAYS
operate the system in
WHM mode. Operation in WHM mode ensures that the system flow will be divided between at
least 2 or more units as demand increases. In addition, WHM ensures that all units receive equal
run time and additional hot water boilers are activated based on the “NEXT ON” firing rate setting.
In case of pre-heated DHW systems with multiple Innovation units, it is highly recommended to
lower the “NEXT ON” setting to 30 - 40% (Default = 50%), so that subsequent Hot Water Boilers
are engaged sooner to provide more rapid response and divide the system flow over additional
units. In case of DHW pre-heat systems, the required temperature rise through an individual unit
can be much lower to ensure that flow per unit does not exceed 50 gal. (189 L) per minute at any
time.
