LIGHTING

INSTRUCTIONS

1.STOP! Read the safety information, column 2 page 14.

2.Make sure equipment shutoff valve is fully open.

3. Turn thermostat control knob clockwise Clockwise to the OFF position (see Figure 22 or 23 for your model).

4.Wait five minutes to clear out any gas. Then smell for gas, including near the floor. If you smell gas, STOP! Follow “B” in the safety information, column 2 page 14. If you don’t smell gas, go to the next step.

5.Turn thermostat control knob counterclockwise C-clockwiseto the PILOT position. Press in thermostat control knob for 5 seconds (see Figure 22 or 23 for your model).

Note: You may be running this heater for the first time after hooking up to gas supply. If so, you may need to press in thermostat control knob for 30 seconds or more. This will allow air to bleed from the gas system.

•If thermostat control knob does not pop up when released, contact a qualified service person or gas supplier for repairs.

6.Keep thermostat control knob pressed in while pushing down and releasing the ignitor button. This will light pilot. If nec- essary, continue to press ignitor button until pilot lights.

If pilot does not light

• turn thermostat control knob clockwise Clockwise to the

OFF position

•repeat steps 5 and 6

If pilot does not stay lit after several tries

•refer to Troubleshooting, pages 19 through 21

•contact a qualified service person or gas supplier

Until repairs are made, light pilot with match. To light pilot with match, see Manual Lighting Procedure, page 16.

7.Keep thermostat control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob.

Note: If pilot goes out, repeat steps 3 through 7. This heater has a safety interlock system. Wait one minute before light- ing pilot again.

8.Turn thermostat control knob counterclockwise C-clockwiseto the desired heating level. For models, VP16T, VN18T, VP26T, and VN30T, the main burner should light. Set con- trol knob to any heat level between HI and LOW (see Fig- ure 25). For infrastat models, the plaque directly above the pilot should light.

CAUTION: Do not try to adjust heating levels by using the equipment shutoff valve.
