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.

IMPORTANT
The unit is shipped from the factory set up for either Natural Gas or Propane, as
specified by the Style Number on the Sales Order. Perform the appropriate
Combustion Calibration procedures in section 4.3 for Natural Gas, or section 4.4
for Propane.
4.3 NATURAL GAS COMBUSTION CALIBRATION
The Innovation Heater is combustion calibrated at the factory prior to shipping. However,
recalibration is necessary as part of initial start-up due to changes in the local altitude, gas BTU
content, gas supply piping and supply regulators. Start-Up & Registration Test Data sheets are
shipped with each unit. These sheets must be filled out and returned to AERCO for proper
Warranty Validation.
It is important to perform the calibration procedure as outlined below. This will keep
readjustments to a minimum and provide optimum performance.
