ADJUSTMENT

There must be sufficient load to operate the boiler at high fire to perform the following adjustments. Start the boiler and observe proper operating parameters for the system.

Required Tools:

TORX® T40 or 5 mm hex wrench

3 mm or 7/64 inch hex wrench

Combustion analyzer

These boilers are equipped with a combined gas/air control and gas safety shut off control valves. The valve functions in parallel with the variable speed combustion blower to supply the correct gas air ratio for optimum performance and efficiency. The combustion blower speed is controlled automatically and determines the amount of negative pressure experienced by the gas safety shut off/control valves. The gas/air regulator adjusts gas flow to maintain the proper pressure at the outlet nozzle of the associated valve.

SETTING OF THE TEST MODE

On the Burner Home screen, select any individual boiler which will guide to Burner Information screen.
