1. The appliances incorporate a microprocessor based, fully
modulating air/gas ratio control system with direct burner
ignition. This provides a modulated heat output, with internal
frost protection provided as standard. The heat exchanger is
constructed from stainless steel encased in high temperature
polymer.
A combined circulating pump, automatic air vent assembly,
pressure gauge, safety valve and system expansion vessel are
included.
Isolation valves are fitted to the service connections.
The boiler has a pump over run feature therefore the central
heating system must include either a proprietary automatic
bypass valve or a radiator must be fitted with lock shield
valves. A separate CH expansion vessel is not required if the
total CH system content is less than 84 litres. However one is
required for systems with volumes greater than 84 litres; refer
to section 6.5. It is recommended that a drain cock is fitted at
the lowest point in the system.
