Follow the wires to a white clip and disconnect it. Disconnect the gas pipe from the gas supply inlet by removing the C‐Clamp at the bottom of the gas pipe (Figure 2). For easier access remove the mounting plate with the current leakage safety device in front of the gas pipe. Disconnect White Clip 6) Then locate and remove the 4 screws with a Philips screwdriver (Figure 1). Do NOT use a power drill. Once screws are removed, pull the gas pipe from the gas fitting. When the pipe and manifold have been detached, remove the gas pipe from the manifold inlet. Remember to remove the manifold screw. This will be used on the new manifold plate. Discard the original manifold plate. Remove Manifold Screw O‐Ring GRAY BLACK ORANGE RED BLUE Gas Pipe Gas Pipe O‐Ring WHITE ...

- Page 7 10) Make sure that the O‐Ring is secured properly in place. Failure to do so will cause gas leaks, possibly resulting in severe personal injury or death. 11) Once O‐ring is in place, slide the gas pipe into the manifold inlet. Make sure that the gas pipe is completely inserted into the manifold inlet in order to prevent any gas from leaking. 12) Insert gas pipe into the gas supply inlet and hold the manifold plate in place. 13) Secure the new manifold plate to the unit using the screws removed in Step 7. The screws need only to be hand tightened and should not be tightened using a drill. First, insert screws 1‐4 from Figure 1, but do not fully tighten these screws. Once all screws are inserted, proceed to completely tighten screws 1‐4. NOTE: When tightening the screws, be certain to not apply excess force as the screws should turn easily. If extra force is required, stop, remove the screw and tighten by hand first. Excess force can strip out the original holes. 14) Attach C‐Clamp at the bottom of the gas pipe (Figure 2). Failure to do so will cause gas leaks, possibly resulting in severe personal injury or death. 15) Reconnect the white clip that contains the wires to the electrical solenoids on the manifold from the locations indicated in Figure 1. 16) Before replacing the front cover, the unit must be adjusted and tested as described in the next section. Adjustments: 1) Before electrical power is applied to the unit, install a remote controller to the unit if it is not already installed. 2) Reconnect the electrical power to the unit. ...

The priority light should be flashing on both item numbers after pressing the “FLOW METER ALARM SET”. 6) Choose the proper conversion setting from the chart below and set the “A1” Maintenance Writer item number according to the chart below. NOTE: DO NOT change the other item numbers. This will cause a fault in the water heater. Models Desired Gas Type NRC98‐DV, NRC98‐OD, ON: “Priority” light is flashing. Natural Gas ON GQ‐C2857WS‐FF US, OFF: “Priority” light is off. GQ‐C2857WS US, Propane OFF NRC83‐DV, NRC83‐OD 7) After setting the “A1” item number for the desired gas type, press and hold the “up” and “down” buttons together for five seconds to confirm the new settings. The remote controller will emit a tone and the display will go blank when the settings are confirmed. If this is not done, the unit will not put the setting changes into effect. NOTE: The setting changes can be cancelled by pressing the Power ON/OFF button before confirming the settings, or if the unit is left alone for ten minutes without confirming the settings. If the default setting needs to be changed again, disconnect the electrical power to the unit, reconnect it and repeat this procedure. Testing: ...

Turn on gas supply to unit and confirm the supply pressure. 3) After supply pressure to heater has been confirmed, turn off the gas supply, remove the manometer tube and replace the hex head screw. 4) The manifold pressure will also have to be checked using a manometer (digital manometer is FIGURE 6 suggested). In order to check the gas manifold pressure, a tap is provided on the manifold plate inside the unit (Figure 7). The pressure can be checked either by removing the Philips head screw (1) and connecting a manometer with a silicon tube, or by removing the 1/8” NPT screw (2) with an Allen wrench and connecting the appropriate pressure gauge. Be sure to zero out the manometer before attaching it to the tap. Turn on the gas supply to the unit. FIGURE 7 6) Before firing the unit, check for gas leaks at the gas inlet fitting and around the manifold plate using a gas leak detection device. 7) If not already on, press the Power “ON/OFF” button so that the unit is in standby mode. The priority light should be on. 8) Open up several hot water fixtures (high flow rate is required through the unit) and allow the unit to go through its startup sequence. It may take several ignition attempts in order to purge air from the gas chambers. If an “11” code appears on the remote ...

Verify from the tables below that the appropriate pressure is read from the manometer. If the pressure needs adjustment, use the manifold pressure increase and decrease buttons to adjust to the correct pressure, while continuing to hold down the maximum pressure set button. 11) Press and hold the minimum pressure set button. Verify from the tables on the following page that the appropriate pressure is read from the manometer. If the pressure needs adjustment, use the manifold pressure FIGURE 8 increase and decrease buttons to adjust to the correct pressure, while continuing to hold down the minimum pressure set button.

Apply conversion labels: 1) Replace the front cover of the unit using the 4 screws previously removed. 2) Locate the 2 conversion stickers in English supplied in the conversion kit. *For water heaters certified for use in Canada locate the 2 conversion stickers in French. 3) Place the sticker indicating the new inlet and manifold pressures directly above the rating sticker so as not to cover any existing markings as indicated by “A” in Figure 10. *For water heaters certified for use in Canada place French sticker with new pressures next to English sticker. 4) Fill out the required information on the remaining sticker indicating the date, gas type, kit number, and name of the company performing the conversion. Place this sticker on the front cover as indicated by “B” in Figure 10. Do not to cover any existing markings. *For water heaters certified for use in Canada place French sticker with agency information next to English sticker. NRC83‐DV, NRC98‐DV NRC83‐OD, NRC98‐OD ...
