ABOUT YOUR WATER HEATER

WATER HEATER APPLICATION

This water heater is designed for use in a single family domestic dwelling for
the purpose of heating potable water. Its use in an application other than this
may shorten its life.

MODEL TYPE

®
The Vulcan water heater model you have
chosen is suitable for outdoor installation only.
Water is stored in a vitreous enamel lined
steel cylinder and heated by a gas burner
located under the cylinder. The heat produced
by the burner is transferred to the water
through the base of the cylinder and through
the wall of a flue pipe which passes through
the centre of the cylinder. A flue baffle in this
flue ensures the efficiency of the water heater
is correct. The gas supply to the burner is
controlled by the thermostat so the water is
heated to a constant temperature.
Automatic safety controls are fitted to the
water heater to provide safe and efficient
operation.

thermostat, which allows you to personally
choose the most suitable temperature for your
