- Page 7 13) Make sure that O‐rings are secured properly in place. Failure to do so will cause gas leaks, possibly resulting in severe personal injury or death. 14) Once O‐rings are attached, 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. 15) Insert Gas Pipe into the gas supply inlet and hold the Manifold Plate in place. 16) Secure the new Manifold Plate to the unit using the screws removed in Step 8. The screws need only to be hand tightened and should not be tightened by using a power 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. 17) 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. 18) Connect the connector ‐ Manifold Plate (Figure 1). 19) FOR NR83‐DVC AND NR83DVC(GQ‐2457WS‐FFA US) ONLY: Attach the O‐ring, feed back pipe, and screw on the Gas Valve as shown in Figure 3. Then attach the Remote Controller with screw. 20) 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 ...

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 and set the “A1” Maintenance Writer item number according to the chart. Note: DO NOT change any other item. This will cause a fault on the unit. Desired Gas Type Natural Gas Propane ON: “Priority” light is flashing. OFF: “Priority” light is off. 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 sound 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: 1) Before turning on the gas supply to the unit, verify that the inlet gas supply pressure is within the following operating ranges: FOR N‐0931M, NR111, AND NC250 SERIES ONLY: a. Natural Gas Supply: Min. 5.0 – Max. 10.5 inches W.C. b.
- Page 9 2) Next, verify the supply pressure at the unit. To check the gas supply pressure to the unit, a tap is provided on the gas inlet (Figure 7). Make sure gas supply is turned off to the unit. Remove the hex head Philips screw from the tap. A 9/32” nut driver is recommended for the removal of this screw. If a nut driver is not available, a Philips screwdriver can be used. Gently remove the screw, so as not to strip out the screw. 3) Connect a manometer to the tap by using a silicone tube. Turn on gas supply to the unit and confirm the FIGURE 7 supply pressure. 4) After checking the gas pressure to the unit has been confirmed, turn off the gas supply, remove the manometer tube and replace the hex head screw. 5) Check the Manifold pressure by using a manometer (digital manometer is recommended). In order to check the gas Manifold pressure, a tap is provided on the Manifold Plate inside of the unit (Figure 8). The pressure can be checked either by removing the hex head Philips 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 931 / NR111 / NC250 Series the tap. 6) Turn on the gas supply to the unit. 7) Before operating the unit, check for gas leaks at the gas inlet fitting and around the ...

Verify from the below table 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. 12) Press and hold the minimum pressure set button. 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 minimum pressure FIGURE 9 set button.

Discard these parts. □ Replace with new Manifold Plate, Burner Damper and O‐rings. □ Make sure that Manifold Plate and O‐rings are secured properly in place. Adjustments: □ Access Maintenance Writer mode and set the A1 item number to desired gas type. □ Confirm gas type settings. Testing: □ Before opening gas valve to the unit, verify the gas supply pressure is within operating range of the uint. □ If gas supply pressure is not within specification, adjust the pressure at the regulator or install a secondary regulator on the supply line connected to the unit. □ Remove hex Philips screw from inlet of the unit and confirm gas supply pressure with manometer. Replace screw after confirmation of gas supply pressure. □ Remove hex Philips screw or 1/8” NPT screw from gas valve and connect manometer to Gas Valve. □ Check for gas leaks around gas inlet fitting and Manifold Plate using a gas leakage detector. □ Check and confirm correct Manifold pressures. Make adjustment if necessary. Replace screw after Manifold pressures have been confirmed. □ Perform final gas leak check again with gas leakage detector. ...
