4.3 NATURAL GAS COMBUSTION CALIBRATION
The Innovation Heater is combustion calibrated at the factory prior to shipping. However, recalibration as
part of initial start-up is necessary due to changes in the local altitude, gas BTU content, gas supply piping
and supply regulators. Factory 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 following procedure as outlined. This will keep readjustments to a minimum
and provide optimum performance.
1. Open the water supply and return valves to the unit and ensure that the system pumps are running.
2. Open the natural gas supply valve(s) to the unit.
