Electrical Requirements - Baxi PREMIER PLUS 800L Installation And User Instructions Manual

4. ELECTRICAL REQUIREMENTS

4.1 The BAXI Premier Plus water heater is suitable for use with most gas or oil
fired boilers provided the boiler has adequate thermostatic control and over-
temperature protection. If in doubt consult the boiler manufacturer.
4.2 The primary flow from the boiler MUST be pumped. Gravity circulation will not
work due to the special design of the primary heat exchanger. It is recommended
that an air bleed point or automatic air vent is incorporated into the highest point in
the system.
4.3 The water heater is fitted with a control thermostat suitable for the control of the
sanitary water storage temperature. This thermostat should be connected, via the
terminal block provided, to the primary heating circuit controls. See diagrams 5
and 6, page 7 for wiring information.
