The incorrect pilot flame is not touch-ing the thermocouple. This will cause thethermocouple to cool. When the thermo-couple cools, the heater will shut down.If pilot flame pattern is incorrect, as shownin Figure 35• turn heater off (see To Turn Off Gas toAppliance, page 17 [manually-controlledmodels] or column 2, this page [thermo-stat-controlled models])• see Troubleshooting, pages 20 through 22Thermocouple Pilot BurnerFigure 34 - Correct Pilot Flame PatternPilot BurnerThermocoupleFigure 35 - Incorrect Pilot Flame PatternBURNER PRIMARY AIRHOLESAir is drawn into the burner through theholes in the fitting at the entrance to theburner. These holes may become blockedwith dust or lint. Periodically inspect theseholes for any blockage and clean as neces-sary. Blocked air holes will create soot.5. Turn control knob counterclockwiseC-clockwise to the PILOT position.Press in control knob for five (5) sec-onds (see Figure 32).Note: You may be running thisheater for the first time after hook-ing up to gas supply. If so, the con-trol knob may need to be pressed infor 30 seconds or less. This will allowair to bleed from the gas system.• If control knob does not pop out whenreleased, contact a qualified serviceperson or gas supplier for repairs.6. With control knob pressed in, pressand release ignitor button. This willlight pilot. The pilot is attached to thefront burner. If needed, keep press-ing ignitor button until pilot lights.Note: If pilot does not stay lit, con-tact a qualified service person or gassupplier for repairs. Until repairs aremade, light pilot with match. To lightpilot with match, see Manual Light-ing Procedure.7. Keep control knob pressed in for 30seconds after lighting pilot. After 30seconds, release control knob.Note: If pilot goes out, repeat steps3 through 7. This heater has a safetyinterlock system. Wait one (1) minutefor system to reset before lighting pi-lot again.8. Turn control knob counterclockwiseC-clockwise to desired heating level. Theburners should light.

Thethermostat will gradually modulate theheat output and flame height from higherto lower settings, or pilot, in order tomaintain the comfort level you select.The ideal comfort setting will vary byhousehold depending upon the amount ofspace to be heated, the output of thecentral heating system, etc.Note: Selecting the Hi setting with thecontrol knob will cause the burner toremain fully on, without modulating downin most cases.1.
