NO SPARK AT THE PILOT

1. On/Off switch is not "On" (Position I).

The On/Off switch is located behind the flipdown cover

plate on the front panel strip. See fig. 9.

2. Water flow is not sufficient to activate heater.

Water flow rate at faucet is below minimum flow needed

to activate heater. When temperature adjustment knob is

turned all the way clockwise, the AquaStar model 125X

requires 1/2 gallon per minute flow to activate the heater.

As a reference, this is a flow which would fill a quart jar in

30 seconds. If the temperature adjustment knob is turned

fully counterclockwise, a flow rate of 1.1 gallons/minute is

required to activate the heater.

3. Water inlet filter is clogged

Water flow is restricted, preventing needed flow to activate

heater. Clean water inlet filter screen.

4. Cross over in water lines

To confirm there is no cross-over in the plumbing, shut off

the cold water supply to the AquaStar water heater and

open a hot water faucet. There should not be any water

flowing at that faucet. Water running is a sign of a plumbing

cross-over. Consult your plumber.

5. Batteries are weak

The LED light (seen through the peephole in the coverplate

on the front panel) flashes when the batteries are less

than 1.2 volts. Replace batteries with D cell (1.5 volt) long

life alkaline batteries as shown in fig. 9.

6. Microswitch needs to be adjusted or replaced.

If you do not hear a click when a tap is opened, the

microswitch needs to be adjusted. See Fig. 12 for

adjustment, or replace the microswitch if the heater has

been in use for some time.

7. Cold incoming water connection made to wrong

side of heater

Make sure cold water inlet connection is on the right side

of heater when you are facing heater.

8. Water valve parts may be dirty or components

damaged

First check that venturi is free of dirt particles. Water valve

and component parts must be totally free of dirt. In hard

water areas, mineral deposits can eventually (3-5 years in

hard water areas) corrode the water valve parts to a point

where they will need replacing. Any sign of moisture at

the bleed hole is a sign that the water valve

components need to be replaced immediately.

9. Loose connection at the ECO

Ignition sparker will not operate if the electrical circuit is

interrupted. Check that the connections to the ECO are

secure and tighten if necessary.

SPARKS APPEAR AT PILOT WHEN HOT WATER TAP

TURNED ON, BUT PILOT AND BURNERS WILL NOT

IGNITE

1. Air in the Gas Line

Normally this is a problem at time of initial installation, after

the pipes have been worked on, or after a gas supply line

has been allowed to empty. Bleed the air trapped in the

gas line by turning the hot water faucet on and off until the

air has been cleared from the line.

2. No gas to the AquaStar

A. Gas cock on gas line may not be open

B. Gas regulator may be shut or damaged. Replace or

unjam the regulator. Note: The regulator furnished with

the heater is exclusively designed for low gas pressure.

Excessive pressure will lock it up. Jamming usually

happens when using propane gas if f the gas pressure

between the gas tank and the water heater's gas regulator

has not been reduced. See Page 2 for recommended

correct gas pressure. To unjam a regulator, consult your

gas supplier or call CEC.

3. Pilot orifice or gas valve is dirty

Clogging of the pilot burner can be caused by dust in the

air or dirt in the gas. The pilot orifice or gas filter may need

to be cleaned or replaced.

4. Water valve assembly needs to be checked

If the pilot orifice is clean, the water valve assembly should

be checked. The adjustment screw on the water valve

micro-switch may not be tight enough (Fig. 12). Remove

central cap beneath micro-switch assembly, carefully

loosen the adjustment screw until the pilot light ignites. At

that point retighten the screw one and a half turns.

5. Pilot electrovalve switch may need to be replaced

(See Fig 13).

Call CEC.

6. Electronic Control Box may need to be replaced

(See Fig 13).

Call CEC.
