Gas smell, Condensation | A.O. Smith EQ 280 G, EQ 380 G instruction

Flue down draught safety device If the flue tube safety device has

switched off the appliance, the appliance can be put back into operation through the normal procedure. If the flue tube safety device repeatedly puts the appliance out of operation then this points to problems with the flue. The only remedy is to determine the cause of the problem (for instance a blocked chimney) and to solve the problem.

Hot water temperature too low

1.Check the setting of the temperature control knob;

2.Check whether the pilot is alight. If necessary ignite (see “Putting into operation”);

3.Check whether there are any leaks or open taps;

4.Is the gas supply adequate? Check and correct if necessary;

5.Perhaps the hot water consumption is higher than was originally calculated;

6.Check whether the cold water inlet has been correctly connected.

7.Check the thermostat sensor for scale build up.

Hot water temperature too high Check whether the control

thermostat is set too high.

Possible water leakage

1.Check whether the drain tap is fully closed;

2.Check whether all water connections are water tight;

3.Check whether the possible water leakage could be caused by condensation.

2.11Gas smell

Warning

Immediately shut the main gas tap. Do not light any fire or switch on any lights, do not use any electrical switches or alarm bells. Open windows. Thoroughly inspect all gas connections and, if the gas smell

persists, alert the local gas company and/or your installer.

2.12 Condensation

If the appliance is filled with cold

water or if the hot water consumption is very high, condensation of flue gasses will occur on the cold surfaces of the combustion chamber and the flue tube. The water drops will fall on the burner and cause a sizzling noise. This is a normal phenomenon that will disappear as soon as the appliance reaches its normal operating temperature.

2.13 IMPORTANTWARNING

The applicance should NEVER be taken into operation with a closed cold water supply!

Provision should always be made for expansion.
