Troubleshooting

5.3Pilot will not stay lit when manually lit (1600P and 425PN) or will not spark automatically with hot water flow (1600H and 425HN)

1.Check the linear safety spillage switch reset button to see if it is tripped (See Section 2.6). Overheating or loss of power to the unit will trip the safety spillage switch and stop the flow of gas.

2.Check the entire pilot safety circuit (including the safety spillage switch) for loose or dirty connections (See Fig 8). Clean any corrosion evident with a pencil eraser or light sandpaper.

3.Pilot flame is weak or yellow. Consult water heater installation manual for instructions on cleaning the pilot assembly.

5.6Noise when power vent motor is running

1.Ensure power vent motor is mounted level with motor shaft horizontal to prevent premature motor bearing wear.

2.Ensure power vent motor is mounted using the supplied vibration mounts to prevent premature motor bearing wear.

3.Remove vent pipe connection from water heater to power vent motor. Inspect internal fan wheel for broken fins. If any damage is evident, order online or call Technical Support (800) 642-3111 for a replacement wheel kit.

5.4Spark but pilot will not light (1600H and 425HN only)

1.Check time delay relay for proper setting. See Section 3.1.1. Set time delay relay adjuster to the

(2) second position for 1600H and 425HN only. If the pilot will not consistently light, move adjuster to the (3) second position and to (4) second position if needed. DO NOT exceed position (4). Complete saftey interlock test after changing setting. See Section 3.1.3.

5.5Pilot and/or burners go out during hot water use

1.Inspect entire vent system for blockage or obstruction. Ensure the back draft flapper installed on the power vent hood swings freely.

2.Verify power vent fan operates with water flow. If not, verify wire connection from flow switch to fan motor. Clean cold water inlet filter and verify flow rate through the water heater is adequate enough to activate the flow switch. If flow rate is more than 0.5 GPM, the flow switch may be defective and should be replaced.

3.If heater is newly installed, verify power vent fan motor is not installed backwards (See Fig 4).

4.Ensure power vent motor is mounted as close as possible to the VH1-4 vent hood. Mounting the power vent motor directly on top of or close to the water heater, may result in lifting flames and pilot outages. Vent pipe length must be at least 2 feet.
