Unit attempts to ignite but fails

Hot water is not available when a fixture is opened.

• Is water running?

• Check for reversed plumbing or crossed pipes.

• Check water filter. (

• Reset unit and try again. There may be air in the gas line.

• Have a professional check the gas supply pressure.

p.20 )

Temperature

•Are the gas and water supply valves fully open?

• Is the water supply cut off?

•Is the hot water fixture sufficiently open? Is the gas being cut off by the gas meter ?

•

(Can other gas devices such as stoves be used?)

•(For LP) Is there enough gas in the tank? (Can other gas devices such as stoves be used?)

• Is the water filter clogged? (

• Is the power button turned on?

p.20 )

No water is available when a fixture is opened.

The hot water is not the correct temperature.

Water takes time to become hot when turning the hot water fixture.

The water is too hot.

• Is the water supply cut off?

• Is the heater frozen?

•Is the hot water fixture sufficiently open?

• Have you allowed enough time for the cold water in the pipes to drain out?

•Are the gas and water supply valves fully open?

• Is the water temperature setting appropriate?

(

p.12 and p.13)

• If the water supply temperature is high, it is possible

for the temperature to be higher than the temperature set on the remote controller.

• If only a small amount of hot water is demanded, it is

possible for the temperature to be higher than the temperature set on the remote controller.

• If the supply water goes through a solar pre-heating

system, it is possible for the temperature to be higher than the temperature set on the remote controller.

Troubleshooting-2

Temperature

The water is not hot enough.

The water is cold when only a single fixture is open.

Fluctuations in hot water temperatures.

The amount of hot water at a certain fixture is not constant.

•Are the gas and water supply valves fully open?

• Is the water temperature setting appropriate?

• If the amount of hot water required is very high, it is possible for the temperature to be lower than the temp erature set on the remote controller. Decrease the amount of water passing through the unit and the temperature should stabilize.

• The unit will not heat the water if the flow rate is less than

0.7 gallons per minute. Open the fixture more or open other fixtures so that a greater flow passes through the unit, and the unit should begin heating again.

• Set water temperature at 115°F to 120°F. This will allow you to use a higher flow of hot water thus meeting the minimum flow requirement of 0.7 gpm.

• Clean the water filter of any debris (

Amount of Hot Water

•When hot water is demanded at other fixtures, the amount available may be reduced. The maximum flow available from this unit is 13.2 GPM at a 45°F temp. rise.

• Pressure fluctuations and other plumbing conditions can cause the temperature and pressure at a fixture to be unstable, but it should stabilize after a short time.

• There are some types of hot water taps that discharges large

volumes of hot water initially, but stabilize after time.

•To keep the temperature stable, the heater limits the amount of water that can flow through it to a small amount initially, but the amount increases over time.

p.12 and p.13)

(

p. 20)

The amount of hot water in the tub is less/more than the set amount.

The flow meter alarm does not sound even when filled to the set amount.

Amount of hot water available has decreased over time.

•When hot water is used for other fixtures while filling the bath tub, the tub will not fill as much.

• If there is water in the tub already, or when filling is stopped and resumed, the tub will fill more.

•

The flow meter alarm is set to sound when hot water is continuously discharged for the set volume of water. If mixing valves are used, or if cold water is mixed with hot water at the fixture, the tub will fill more than the setting of the flow meter alarm.

• Is the water filter clogged? (

p.20 )

Remote Controller

The light on the power button does not come on.

The water temperature changes after a power failure or when the power is disconnected.

The fan can be heard after operation is stopped.

A motor can be heard when turning the unit ON or OFF, when opening or closing a fixture, or after the unit has been running for a while.

The fan can be heard when it is very cold outside.
