4.5 WATER CONNECTIONS
The diagram below indicates the plumbing connections at the rear of the boiler.
The boiler can be plumbed into either an open vented system (the maximum static head of water
permissible is 90 ft. (27.44 meters) or a sealed system. If plumbed into a sealed system an
appropriately sized expansion vessel should be used and installed as per manufacturers
instructions. The expansion vessel should be sized based on the water capacity in the boiler and
the water in the entire heating system.
Incorrectly sized expansion vessel will
invalidate the warranty. A minimum
18 litre vessel is recommended for
the boiler plus additional expansion
for the heating and domestic hot
water system.
The pump is on the return pipework just before the boiler. It is recommended that a by-pass pipe
between the flow and return is used with a valve to regulate the temperature of the water
returning to the boiler. Also, the system designer should ensure that there is adequate provision in
the system for heat dissipation from the boiler during the shut-down / extinguishing phase..An
automatic air vent and pressure relief valve must be fitted to the flow pipework immediately
outside the boiler. The pressure relief valve should be piped to a drain to prevent injury to the
User or Service Technicians if it is activated. All
unused connections should be sealed with
blanking plugs.
A non-return valve should be fitted to prevent back-siphonage

Ensure that the pre-charge in the
vessel is equal to the initial system fill
pressure of between 1-1.5 bar.
