SINGLE STAGE UNITS ONLY
The gas valve regulator spring must be replaced on all single stage gas furnaces and packaged gas/electric units.
Replace the gas valve regulator spring with the propane gas regulator spring from the proper spring kit. Follow the
manufacturer’s instructions provided in the spring kit. Discard all unused spring kits. Two-stage units do not
require a spring change.
