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

®
Vulcan water heater models are available with either a single heating unit or
with twin heating units (refer to
Element Model"
on page 7). The water heaters are suitable for either indoor or
outdoor installation.
Water is stored in a vitreous enamel lined steel cylinder and heated by the
electric immersion heating unit. The thermostat controls the temperature.
Automatic safety controls are fitted to the water heater to provide safe and
efficient operation.
The 025, 045 and 050 model water heaters have connections on either side of
the tank. Depending on the model, it may have caps or brass plugs on one side
of the tank. The plugs and caps block off the alternative connection points and
are not to be tampered with or removed.

MAINS PRESSURE

The water heater is designed to operate at
mains pressure by connecting directly to
the mains water supply. If the mains supply
pressure in your area exceeds that
on page 22, a pressure limiting valve must
be fitted. The supply pressure should be
greater than 350 kPa for true mains
pressure operation to be achieved.
HOW HOT SHOULD THE WATER BE?
The water heater features an adjustable
thermostat, which allows you to choose the
most suitable temperature for your hot
water needs.
