On all control type units, the inlet connection is on the right side of unit. To connect from the opposite side, route the pipe around the back portion of the unit. When tightening up the joint to the valve, hold the valve securely to prevent movement. Test all gas joints from the gas meter to the heater valve for leaks using a gas analyzer or soap and water solution after completing connection. DO NOT USE AN OPEN FLAME. Check the gas pressure with the appliance burning and the control set to HIGH. Test Port “OUT” MILLIVOLT VALVE CONTROL (Figure 16) The valve regulator controls the burner pressure which should be checked at the pressure test point. Turn captured screw counter clockwise two or three turns and then place tubing to pressure gauge over test point (Use test point “OUT” 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. Figure 16 - Pressure Test Point LocationMillivolt Control 20 81D0107 ELECTRICAL WIRING (MILLIVOLT) The Millivolt valve is a self-powered combination gas control THAT DOES NOT REQUIRE 110 VAC TO OPERATE. CAUTIONLabel all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous operation. Verify proper operation after servicing. ODS On/Off Switch or Optional Wall Switch, Remote or T-Stat Figure 17 - Wiring Diagram Note: Log switch wires are not factory connected. Connect log switch wires to the TH/TP and TH valve terminals as shown. Log Switch Pilot Millivolt Valve TH = 3 TP = 1 TP/TH = 2 ODS Pilot CONNECTING OPTIONAL WALL SWITCH OR THERMOSTAT 1. Use 18 awg, two-wire cable, 15 feet maximum length. 2. At one end of the cable, connect both wires to the wall switch or thermostat. At the other end, connect one wire to TP/TH and one wire to TH, or connect the wall switch/thermostat to the two male (0.25") terminals on the left side of the unit. The color of the wires does not matter. 81D0107 21 ELECTRICAL WIRING (MILLIVOLT) CONNECTING REMOTE RECEIVER 1. Set remote receiver. See instructions included in receiver kit. 2. Connect the two (2) 1/4" female connectors to the TP/TH and TH terminals on the control valve. Remote Wire Connectors Remote Wire Connectors NOTICEDo not let wires touch grate or burner. Remote Receiver Valve Figure 18 - Installing Remote Receiver Note: Heat reduces battery life. You can protect the receiver and extend battery life by mounting receiver in wall or other location outside the fireplace. CHECKING SYSTEM OPERATION The Millivolt system and individual components may be checked with a Millivolt meter having a 0-1000 mV range. Conduct each check shown in chart below by connection meter test leads to terminals as indicated. CHECK TEST A B CONNECT METER LEADS TO TEST TO TERMINALS COMPLETE 2 & 3 SYSTEM THERMOPILE 1 & 2 OUTPUT SWITCH OR THERMOSTAT CONTACTS METER READING SHOULD BE CLOSED MINIMUM 175 OPEN MINIMUM 500 A. COMPLETE MILLIVOLT SYSTEM CHECK (“A” Reading - Thermostat contacts CLOSED - Control Knob “ON” - Main burner should turn ON) a. If the reading is more than 175 Millivolts and the automatic valve still does not come on, replace the control. b. If the closed circuit reading (“A” reading) is less than 175 Millivolts, determine cause for low reading, proceed to Section B below. B. Thermopile Output Reading Check (“B” Reading - Thermostat contacts OPEN - Main burner OFF) 1. Check gas pressure to the unit. If gas pressure is within minimum and maximum on data plate, then check pilot voltage, 500 Millivolts minimum. If the minimum Millivolt reading is not obtainable, replace pilot. 22 81D0107 LOG PLACEMENT Before you begin — This unit is supplied with seven (7) ceramic fiber logs. Do not handle these logs with your bare hands. Always wear gloves to prevent skin irritation from ceramic fibers. After handling the logs, wash your hands gently with soap and water to remove any traces of fibers. The positioning of the logs is critical to the safe and clean operation of this heater. Sooting and other problems may result if the logs are not properly and firmly positioned in the appliance. Never add additional logs or embellishments such as pine cones, vermiculite or rock wool to the heater. Only use the logs and 2G-RW rock wool (for NB18), or 3G-RW rock wool (for NB24) supplied with the unit. Failure to position the parts in accordance with diagrams below or to use only parts specifically approved for this heater may result in property damage or personal injury. WARNING PLACING ROCK WOOL Before installing logs, place rockwool in dime size pieces evenly over small burner ports starting in the rear of the burner going towards the front. Avoid placing rock wool on slots on each side of rear burner and on large yellow flame ports on front of burner. Wash hands after placing rock wool. Itching may occur. WARNING• Use only rock wool provided with log set. • Do not add additional rock wool. Dime-Size Rock Wool Figure 19 - Placi...
