Central Heating Circuit
The appliance is suitable for fully pumped SEALED
SYSTEMS ONLY.
All systems should be thoroughly flushed prior to
connection of the appliance. If the installation is on an
existing sealed system, or a modified open system, it is
particularly important to flush preferably using an
appropriate descaling/flushing agent.
Where used, corrosion inhibitors, flushing agents/descalers
should be approved and suitable for all system metals.
BYPASS
The appliance has an integral pre-set bypass, therefore no
external bypass on the system is required. TRV’s can be -
used on all radiators.
SYSTEM CONTROL
Operation of the system under control of the boiler
thermostat only does not produce the best results. The
heating system should include a control system. This should
comprise of at least a single channel timer.
Integral Single Channel Timer Kits are available as optional
extras.
For optimum operating conditions and best economy the
fitting of a programmable thermostat is recommended.
Programmable thermostats - the ‘Baxi Genesis
Controllers’ are available as an optional extra.
