If you smell gas STOP! Follow “B” in the safety information label. If you do not smell gas, go to the next step. 6. From OFF position, turn the gas control knob counterclockwise to “Pilot” position. Push in and hold control knob for 5 seconds. 7. With the control knob pushed in, push in and release the piezo ignitor button to light the pilot. 8. Continue pushing the control knob in for a further 60 sec- onds to prevent the flame detector from shutting off the gas while the probe is warming up. Release the control knob. 9. Turn gas control knob counterclockwise to the “ON” position. 10. After the pilot has been lit for one minute, the burner can be turned on. Turn the ON/OFF switch to “ON” position or adjust thermostat to desired setting. 11. If the gas logs will not operate, follow the instructions “To Turn Off Gas To Appliance” and call your service technician or gas supplier. Wait 30 seconds before readjusting the heater when the control knob has been turned down to a lower setting. PIEZO IGNITOR HI/LO CONTROL KNOB REGULATOR TO TURN OFF GAS TO APPLIANCE 1. Turn control knob clockwise to OFF position to 2. If applicable: Turn ON/OFF switch to OFF position and/or completely shut off the heater. set thermostat (if present) to lowest setting. If applicable: Turn off all electric power to the heater. 12409-2-0403 Page 17 Page 18 12409-2-0403 Figures 19 and 22 show a correct pilot flame pattern. The correct flame will be blue and will extend beyond the thermocouple. The flame will surround the thermocouple just below the tip. A slight yellow flame may occur where the pilot flame and main burner flame meet. Figures 20 and 23 show an incorrect pilot flame pattern. The incorrect pilot flame is not touching the thermocouple. This will cause the thermocouple to cool. When the thermocouple cools, the heater will shut down. VFYR PILOT Correct appearance of pilot flame. Figure 19 Incorrect appearance of pilot flame. Figure 20 If pilot flame pattern is incorrect, as shown in Figure 20 • See Troubleshooting, page 20. Cleaning and Maintenance/Pilot Oxygen Depletion Sensor Pilot (Figure 21 ) When the pilot has a large yellow tip flame, clean the Oxygen Depletion Sensor as follows: 1. Clean the ODS pilot by loosening nut B from the pilot tubing. When this procedure is required, grasp nut A with an open end wrench. 2. Blow air pressure through the holes indicated by the arrows. This will blow out foreign materials such as dust, lint and spider webs. Tighten nut B also by grasping nut A.

PILOT FLAME CHARACTERISTICS 12409-2-0403 Page 19 WIRING Millivolt Control The valve regulator controls the burner pressure which should be checked at the pressure test point. Turn captured screw counter clockwise 2 or 3 turns and then place tubing to pressure gauge over test point (Use test point “A” closest to control knob). After taking pressure reading, be sure and turn captured screw clockwise firmly to re-seal. Do not over torque. Check for gas leaks. Wiring Diagram (Figure 25) Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing. 16", 18", 24" and 30" Gas Logs (Millivolt) thermopile is self powered gas valve and does not require 110 volts. Refer to (Figure 25) to provide optional wall switch, thermostat, or remote control. Maximum length of 20 feet of 18 AWG to conductor wires is to be used with all optional switches. Use the two leads (Red and Green wires) to attach optional components. Check System Operation Millivolt system and all individual components may be checked with a millivolt meter 0-1000 MV range. Remote Receiver -VFYR-(16, 18, 24, 30) Use the following steps to place the remote receiver adjacent to the gas valve. Attention: 1. The remote receiver can not be placed behind the gas valve and burner assembly. 2. When facing the appliance, the remote receiver must be placed to the right of the gas valve and burner assembly. Note: Do not let remote control receiver come in contac...
