900RX PILOT LIGHTING PROCEDURE
1. Turn all thermostats to the OFF position. Wait 5 minutes to allow any gas that may have
accumulated in the burner compartment to escape.
2. Turn on the main gas shut-off valve.
3. Push the power switches to ON. The switches will illuminate and you will hear a “clicking” sound.
4. Depress and hold the red buttons on the pilot safety valves while the electric igniters light the
corresponding pilots. You will have to monitor the pilot burners through the pilot sight holes. The
pilot burners are aligned with the red buttons on the pilot safety valves and the pilot sight holes.
The
p
ilot burners are inset 12” from the front of the unit.

4. Watch for the pilot burners to ignite. When the gas at the pilot has been burning for about 45
seconds, release the corresponding red button. If the pilot does not remain lit, repeat the
procedure allowing more time before releasing the button.
5. The pilot burners can be lit manually in the event of a failure of the electronic ignition system. If
this happens, repeat steps 1-4 with the power switch in the OFF position. You will have to reach
under the front of the unit and through the pilot cutout to ignite the pilots with an outside ignition
source(such as a lit taper, etc.) while again depressing the corresponding red button.
5. If after completing steps 1 -5 and the pilot does not light, turn off the main gas shut-off to the
unit and contact an authorized service agency.
