WARNING

If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or death.

BEFORE OPERATING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor. Use only your hand to push in or turn the gas control knob or lever. Never use tools. If the knob or lever will not push in or turn by hand, do not try to repair it, call a qualified ser- vice technician. Force or attempted repair may result in a fire or explosion.

To place G20E or G20X furnace into operation:

G20E or G20X units are equipped with an intermittent pi- lot ignition system. Do not attempt to manually light pilots on these furnaces. Each time thermostat calls for heat, the pilot will automatically light. The pilot does not burn when there is no call for heat on units with electronic igni- tions.
