Troubleshooting & Maintenance
Q: Why isn't there enough water pressure from the heater? A: If the pressure being supplied into the water heater is low, the pressure coming out of the water heater will also be low. If the supply pressure is normal and the water pressure is still low, the water heater may be too small for your application. Contact your authorized installer about replacing your heater with a larger one. Q: What should I do if there is water dripping from the relief valve on the outlet of the heater? A: This may be a failure of the relief valve, or a response to dangerously high temperatures or pressures in the water heater. Contact a plumber to have this problem checked. Q: Why do I not get any hot water when I turn the hot water on just a little? A: Because a tankless water heater works differently than a tank-type water heater, a tankless heater will not turn on unless the minimum flow rate is met. The required minimum flow rate is 0.5 GPM (0.7 GPM on N-1321M model), which means the heater will not ignite its burner to heat water unless there's a demand for hot water that is equal to or greater than 0.5 GPM. |
