Figure 13 Oxygen Depletion Sensor Pilot (Figure 14) 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. Figure 14 Warning: Never use needles, wires, or similar cylindrical objects toclean the pilot to avoid damaging the calibrated ruby thatcontrols the gas flow. THERMOSTAT OPERATION To ignite main burner, turn gas control knob counterclockwise toward HI setting. To shut down main burner, turn gas control knob clockwise toward LO setting. The SR-10T has an input of 10,000 BTUH (2.9KW/H). The hydraulic thermostat bulb is located at the casing assembly bottom. When the hydraulic thermostat bulb senses the need for heat, the unit cycles .ON. at a full input rate of 10,000 BTUH (2.9KW/H). The unit remains at this full input rate until the hydraulic thermostat bulb is .satisfied.. When the hydraulic thermostat bulb is .satisfied. the burner will shut .OFF. with the pilot flame remaining .ON.. The SR-18T has an input of 18,000 BTUH (5.3KW/H). The hydraulic thermostat bulb is located at the casing assembly bottom. When the hydraulic thermostat bulb senses the need for heat, the unit cycles .ON. at a full input rate of 18,000 BTUH (5.3KW/H). The unit remains at this full input rate until the hydraulic thermostat bulb is .satisfied.. When the hydraulic thermostat bulb is .satisfied. the burner will shut .OFF. with the pilot flame remaining .ON.. Note: The burner does not modulate between .ON. and the pilot flame. When the SR-18T is .ON,. all three ceramic plaques will .glow.. There will never be a time when only one or two ceramic plaques are .glowing.. The SR-30T has an input of 30,000 BTUH (8.8KW/H). The hydraulic thermostat bulb is located at the casing assembly bottom. When the hydraulic thermostat bulb senses the need for heat, the unit cycles "ON" at a full input rate of 30,000 BTUH (8.8KW/H). The unit remains at this full input rate until the hydraulic thermostat bulb is "satisfied." When the hydraulic thermostat bulb is "satisfied" the burner will shut "OFF" with the pilot flame remaining "ON." Note: The burner does not modulate between "ON" and the pilot flame. When the SR-30T is "ON," all five ceramic plaques will "glow." There will never be a time when only one or three ceramic plaques are "glowing." The LO and HI setting has temperature range of approximately 55°F (12.78°C) to 90°F (32.22°C), respectively. This is the temperature at the hydraulic thermostat bulb not the room temperature. The owner is advised to determine the particular heat setting that is desired for comfort, as heating requirements are different for every owner. Attention: If the owner does not want the main burner to ignite and turns the gas control knob to the LO setting, the main burner will still ignite if the temperature at the hydraulic thermostat bulb drops to 55°F (12.78°C). If no heat is desired, turn the gas control knob to the PILOT position. Main Burner Operation Description of Gas Control Knob: OFF position. PILOT position. LO/HI will allow the hydraulic thermostat bulb to cycle the heater ON and OFF. Page 14 16009-1-0504 APPLIANCE MAINTENANCE APPLIANCE MAINTENANCE Removing Pilot/Thermocouple From Main Burner Assembly Attention: The thermocouple CAN NOT be replaced as an individual item. You must order a new pilot when replacing thermocouple. 1. Turn OFF gas supply to the heater. 2. Turn OFF electrical supply to the heater if optional blower is installed in heater. 3. Remove lower louver from casing assembly (2 screws). 4. Remove reflector from casing assembly (2 screws). 5. Disconnect pilot tubing from pilot (see Figure 14, Page 14). Grasp nut A with a wrench when removing nut B with a second wrench. 6. Remove pilot from pilot bracket (2 screws). 7. Remove thermocouple lead from gas valve. 8. As parts are being replaced in reverse order, check for gas leaks at all gas connections before lower louver is replaced onto casing assembly. Removing Main Burner Orifice(s) From Main Burner Assembly 1. Turn OFF gas supply to the heater. 2. Turn OFF electrical supply to the heater if optional blower is installed in heater. 3. Remove lower louver from casing assembly (2 screws). 4. Remove reflector from casing assembly (2 screws). 5. Remove pilot bracket from main burner assembly (2 screws). 6. Pivot pilot bracket with attached pilot away from main burner assembly (do not damage pilot tubing). 7. Disconnect supply tubing from orifice holder(s). 8. Remove orifice holder from venturi of main burner assembly (1 screw for each orifice holder). 9. Remove main burner orifice from orifice holder. Attention: The number stamped on the main burner orifice is a millimeter diameter. 10.As parts are being replaced in reverse order, check for gas leaks at all gas connections before lower louver is replaced onto casing assembly.
