8. Hold the control knob in for an additional 10 seconds to prevent the ODS pilot from shutting off the gas while the thermocouple is warming up. 9. Release the control knob. * If the knob does not pop out when released, stop and immediately call your service technician or gas supplier. * If the ODS pilot will not stay lit after several tries, push and turn the gas control knob clockwise to OFF and wait 15 seconds. Repeat steps 6 through 9. 10. Push in control knob and turn to desired setting (1, 2, 3). The control knob must be set at either the low or high position, and the control knob will pop out when positioned correctly. Do not set the control knob at a position between pilot (1, 2, 3). TO TURN OFF GAS TO APPLIANCE 1. Turn control knob clockwise to OFF position to completely shut off the heater. PILOT FLAME CHARACTERISTICS Figures 16 and 19 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 17 and 20 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. VFSR Pilot Correct pilot flame pattern. Figure 16 Incorrect pilot flame pattern. Figure 17 If pilot flame pattern is incorrect, as shown in Figure 17 • See Troubleshooting, page 21. Cleaning and Maintenance/Pilot Oxygen Depletion Sensor Pilot (Figure 18 ) 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. Figure 18 VFSV and VFSM Pilot Correct Pilot Flame Pattern Figure 19 Incorrect Pilot Flame Pattern Figure 20 If pilot flame pattern is incorrect, as shown in Figure 20 • See Troubleshooting, page 21. 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. CAUTIONNever use needles, wires, or similar cylindrical objects to clean the pilot to avoid damaging the calibrated ruby that controls the gas flow. Figure 21 PILOT FLAME CHARACTERISTICS (continued) CLEANING AND SERVICING Annual inspection and cleaning by your dealer or qualified service technician is recommended to prevent malfunction and/or sooting. TURN OFF HEATER AND ALLOW TO COOL BEFORE CLEANING. Remove logs, handling carefully by holding gently at each end. Gloves are recommended to prevent skin irritation from ceramic fibers. If skin becomes irritated, wash gently with soap and water. Refer to manual for correct log placement. PERIODIC CLEANING – Refer to parts diagram for location of items discussed below. • Do not use cleaning fluid to clean logs or any part of heater. • Logs - brush with soft bristle brush or vacuum with brush attachment. • Remove loose particles and dust from the burner areas, controls, piezo covers and grate. Don’t remove media from insid...
