Gas supply to both
pilot and main burner will now be shut off. Check through the viewing
window that the pilot flame is extinguished.
The summer-winter switch reduces the pffect of seasonal variation in water
supply temperature, so that in winter and summer hot water at a similar
temperature is obtained.
The summer-winter switch should be turned to the summer posItIon in the
warm summer and autumn months and to the winter position in the cold
winter and spring months. There is no advantage in frequent adjustment of
the switch as the water supply temperature varies slowly through the year.
If installed in a hard water area correct use of the summer-winter wi1l
reduce the risk of scaling.
NOTE: Should the water flow through the appliance be greater than
NORMAL, either by option or because of supply pressure variation, cooler
hot water will be obtained and the summel-winter switch will have no
effect. Reduction of water flow at the top will restore the temperature
and the action of the summer-winter switch.
The heater casing is stoved enamel and should be cleaned with warm, soapy
water. DO NOT USE ABRASIVE POWDERS SINCE THEY WILL SCRATCH
THE PAINTED SURFACE.
