Note:The burner may light if hand-held remote ON button was on when selector switch was last turned off. You can now turn the burner on and off with the hand-held remote control unit. IMPORTANT: Do not leave the selector switch in the REMOTE position when the pilot is not lit. This will drain the battery. IMPORTANT: Be sure to press the ON/OFF buttons on the hand-held remote control unit for up to 3 seconds to assure proper operation. GHRC Series Operation: 2a. Press the ON/OFF button to turn the burner on and off. When turning burner off, the pilot will remain lit.

Press the AUTO/ON/OFF button on the hand-held remote control (see Figure 22, page 17). The lights to the left of the button will show AUTO, ON, or OFF. • In the ON mode, the burners will ignite. The heater is in manual mode when ON is lit. • In the AUTO mode, the thermostat in the hand-held remote unit controls the room temperature. To increase the room temperature, press the top arrow of the TEMP button. To lower the room temperature, press the bottom arrow of the TEMP button. At higher settings the heater will run longer. Flame Adjustment Knob Figure 22 - Setting the Selector Switch, Control Knob, and Flame Adjustment Knob for Remote Operation Shows Temperature Setting The Log Heater will Automatically Cycle between Pilot and the Heat Setting that has been Selected Figure 23 - Thermostat Hand-Held Remote Control Unit Selections (GHRCTA Series Only) IMPORTANT: This remote control has been specially engineered to take an air temperature sample every 5.5 minutes in the auto mode. It will not respond immediately to the temperature setting being turned up or down. IMPORTANT: The hand-held remote control unit must be near the heater. Do not keep the hand-held remote control unit too close to the heater. The thermostat on the hand-held remote control unit will heat up too quickly and turn the heater off. 3. To turn the burner off, press the AUTO/ON/OFF button until OFF lights. The pilot will remain lit. IMPORTANT: To turn the pilot off, manually turn the control knob on the heater to the OFF position. Control Knob in On Position Increases Room Temperature in AUTO Mode Decreases Room Temperature in AUTO Mode Turns Burners On or Off and Allows You to Choose the Auto Setting INSPECTING BURNERS Check pilot flame pattern and burner flame patterns often. PILOT FLAME PATTERN Figure 24 shows a correct pilot flame pattern. Figure 25 shows an incorrect pilot flame pattern. The incorrect pilot flame is not properly heating the thermocouple. When the thermocouple cools, the heater will shut down. If pilot flame pattern is incorrect, as shown in Figure 25 • turn heater off (see To Turn Off Gas to Appliance, page 15) • see Troubleshooting, pages 17 through 19 Pilot Burner Thermocouple Figure 24 - Correct Pilot Flame Pattern Pilot Burner Thermocouple Figure 25 - Incorrect Pilot Flame Pattern BURNER PRIMARY AIR HOLES Air is drawn into the burner through the holes in the fitting at the burner entrance. These holes may become blocked with dust or lint. Periodically inspect these holes for any blockage and clean if needed. Blocked air holes will create soot. MAIN BURNER Periodically inspect all burner flame holes with the heater running. All slotted burner flame holes should be open with yellow flame present. All round burner flame holes should be open with a small blue flame present. Some burner flame holes may become blocked by debris or rust, with no flame present. If so, turn off heater and let cool. Remove blockage. Blocked burner flame holes will create soot. 16 105194 OWNER’S MANUAL TROUBLESHOOTING Note: For additional help, visit DESA International’s technical service web site at Note: All troubleshooting items are listed in order of operation. OBSERVED PROBLEM When ignitor button is pressed, there is no spark at ODS/pilot WARNING: Turn off heater and let cool before servicing. Only a qualified service person should service and repair heater. POSSIBLE CAUSE 1. Ignitor electrode not connected to ignitor cable 2. Ignitor cable pinched or wet 3. Piezo ignitor nut is loose 4. Broken ignitor cable 5. Bad piezo ignitor 6. Ignitor electrode broken 7. Ignitor electrode positioned wrong CAUTION: Never use a wire, needle, or similar object to clean ODS/pilot. This can damage ODS/ pilot unit. REMEDY 1. Reconnect ignitor cable 2. Free ignitor cable if pinched by any metal or tubing. Keep ignitor cable dry 3. Tighten nut holding piezo ignitor to base panel of log set. Nut is located behind base panel 4. Replace ignitor cable 5. Replace piezo ignitor 6. Replace pilot assembly 7. Replace pilot assembly When ignitor button is pressed, there is spark at ODS/pilot but no ignition 1. Gas supp...
