CHECKING THE GAS PIPING - CONTINUED

When you have determined that there are no leaks in the gas piping system you may purge the system of air. Disconnect the pilot supply tubing from the right side of the valve. See Figure 12.

Turn the knob on the gas valve to the pilot position. Press the knob down and hold until you smell gas at the pilot supply opening. Release the knob and turn it to the off position. Reconnect the pilot supply tubing and check for leaks with soap and water or liquid detergent.

WARNING

When purging gas piping, the area around the floor furnace must be well ventilated to allow any gas to dissipate. Liquid Petroleum (L.P.) Gas is heavier than air and may puddle in low places under the floor. Check thoroughly to determine that no gas is present before lighting the floor furnace. Failure to do so could result in property damage, bodily injury or death.

THERMOSTAT INSTALLATION

Follow the instructions included with the thermostat. Locate the thermostat approximately five feet above the floor. Always mount the thermostat on an inside wall where it won’t be affected by heat or cold sources such as direct sunlight, televisions, fireplaces, hidden hot or cold water pipe, drafts, etc. The thermostat must never be installed in an adjoining room where a door can be closed between the thermostat and floor furnace. This floor furnace is equipped with a self-generating control system. Never connect to a 24-volt transformer or to the household electric system. Do not use more thermostat wire than is included with the floor furnace.
