This furnace does not have a pilot. It is equipped with a hot surface igniter, which automatically lights the burner. Do not attempt to light the burner by hand. Check the following items before the initial start-up.

1.Check all wiring for loose connections and proper hook up.

2.Leak test gas piping connections.

3.Check all tubing to the pressure switch and drains to make sure they are connected firmly at all their connection points.

4.Check flue pipe, combustion air inlet and all PVC connections for tightness and to make sure there is no blockage.

5.Make sure air filter is in place.

6.Make sure the outside vent and air intakes are installed according to instructions and that they are free from blockage.

7.Make sure that the drain trap is properly connected to the furnace and to the buildings drain system.

If excessive gas escapes when purging the gas supply at the union, allow the area to ventilate for at least 15 minutes before attempting to start the furnace. LP gas is especially dangerous because the specific gravity of LP gas allows it to accumulate at floor level at a dangerous concentration. For remainder of operating instructions, reference Users Information Manual.

: Heat exchanger oil will burn off on initial firing creating an unpleasant odor. To prevent this odor from occurring more than once, it is suggested that:
