PRODUCT DESIGN

quired due to the natural reduction in the density of both the gas fuel and combustion air as altitude increases. The kit will provide the proper design certified input rate within the specified altitude range.

High altitude kits are purchased according to the installa- tion altitude and usage of either natural or propane gas. Refer to the chart above for a tabular listing of appropriate altitude ranges and corresponding manufacturer’s high altitude Natu- ral Gas and Propane Gas kits. For a tabular listing of appro- priate altitude ranges and corresponding manufacturer's High Altitude Pressure Switch kits, refer to either the Pressure Switch Trip Points & Usage Chart in this manual or the Ac- cessory Charts in Service Instructions.

of time before stepping up to high stage to satisfy the thermostat’s call for heat. The delay period prior to stepping up can be set at either a fixed 5 minute time delay or a load based variable time between 1 and 12 minutes (AUTO mode). If the AUTOmode is selected, the control averages the cycle times of the previous three cycles and uses the average to determine the time to transition from low stage to high stage.

To use a single-stage thermostat, turn off power to the fur- nace, move the thermostat selection DIP switch to the OFF position. Set the desired transition time by setting the tran- sition delay DIP switch to the desired ON/OFF position. Turn power back on. Refer to the following figure.

Single Stage Thermostat

A single-stage thermostat with only one heating stage may be used to control this furnace. The application of a single- stage thermostat does not offer “true” thermostat-driven two- stage operation, but provides a timed transition from low to high fire. The furnace will run on low stage for a fixed period
