After following these procedures, ignition of the main burner will automatically take place whenever you turn on a hot water tap, since the pilot burner is permanently alight. When you want to switch off the heater, move the slide control to the far left. After a few seconds the pilot flame will go out. If there is a risk of freezing, switch off the appliance and drain the appliance. Danger: the area in front of the burner can reach very high temperatures, and there is a risk of burning on conta

Maximum output is obtained when the slide control is to the far left. In order to optimise energy consumption, adjust slide control position to supply the minimum output required. If there is air in the gas pipe when the appliance is commissioned, this can cause ignition failure. In such cases, the hot water tap should be turned off and then on again so that the appliance repeats the ignition cycle. The procedure should be repeated as necessary until the gas pipe is purged of air. Danger: the ar

NOTICE: Do not remove the anode rod from the water heater’s tank, except for inspection and/or replacement, as operation with the anode rod removed will greatly shorten the life of the glass lined tank and will exclude warranty coverage. 20 Anode Rod This water heater is equipped with an anode rod designed to prolong the life of the glass lined tank. The anode rod is slowly consumed, thereby eliminating or minimizing corrosion of the glass lined tank. Water sometimes contains a high sulfate and/
