WATER HEATER INSTALLATION
LOCATION
When determining the siting of the water heater,
make sure you keep an approx. distance of 50 mm
between the sides of the appliance to ensure total
accessibility for servicing.
The jig will enable you to determine the position of
the flue system hole at the top outlet. All informa-
tion regarding the installation of the flue system is
provided in the flue system package.
If the water-heater is not fitted straight away, the
water and gas fittings must be protected from
contaminents E.G. plaster, paint.
