4. Wait five (5) 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 on page 21. If
you don't smell gas, go to the next step.
5. Slightly depress and turn control knob counterclockwise
position. Keep control knob pressed in for five (5) seconds (see Figure 20, page 21).
Note: You may be running this heater for the first time after hooking up to gas

allow air to bleed from the gas system.
• If control knob does not pop out when released, contact a qualified service
person or gas supplier for repairs.

The pilot is attached to the burner. If needed, keep pressing ignitor button until

Note: If pilot does not light, contact a qualified service person or gas supplier for
repairs. Until repairs are made, light pilot with match. To light pilot with match,
see Manual Lighting Procedure on page 23.

position. The burner should light. Set control knob to any heat level between
HIGH and LO.
VARIABLE CONTROL OPERATION
The variable control valve can be set to any heat setting and flame height desired, by
simply turning the control knob until that setting is attained. Even the lowest setting
provides realistic, dancing yellow flames. Selecting higher settings produces greater
heat output. This results in increased heating comfort.
Do not operate heater between PILOT and HIGH positions.
Do not try to adjust heating levels by using the manual shutoff valve.
