WARNING
There are a number of live tests that are required when fault finding this product. Extreme care should be used at
all times to avoid contact with energized components inside the furnace.
You MUST be a qualified service person before proceeding with these test instructions.
Before checking resistance readings, turn off power source to unit and then isolate each item to be checked from
the circuit by unplugging it.
When setting gas pressures on one of these units, please check the complete model number you are trouble-
shooting. Gas pressures and dip switches can vary among models. Always check the rating plate for complete
information and follow directions.
