1 Description
The VANTAGE range of unvented hot water storage
cylinders are indirectly heated cylinders which are desi-
gned for use with Vaillant gas boilers only. The VANTA-
GE must NOT be installed with boilers supplied by any
other manufacturer.
VANTAGE cylinders are available in three sizes of 120,
150 and 200 litre nominal capacity. The cylinders are of
glass lined steel construction, insulated with CFC free
foam and enclosed in a decorative sheet metal casing.
They are supplied with all necessary cold and hot water
controls and are fitted with a mid position 3 port diver-
ter valve for control of central heating and domestic hot
water.
The VANTAGE cylinders are prefitted with an operating
thermostat for controlling the water temperature.
VANTAGE cylinders are also provided with an auxiliary
back up electric immersion heater, including operating
thermostat and energy cut out.
The VANTAGE cylinders operate using a mains water
pressure supply and do not require a feed from a cold
water storage tank. The VANTAGE cylinders have 22 mm
D. H. W. outlet and cold water mains inlet connections
for optimum flow rate. To achieve optimum performance
from the VANTAGE an adequate cold water mains supply
pressure and flow rate must be available (see section
7.2: Mains Water pressure).
