Boiler Design and Clearances
Description
The boiler is a combined domestic hot water and central
heating appliance. The internal control unit electronically
provides direct burner ignition and combustion supervi-
sion along with continuous modulation of the burner’s gas
supply.
By means of a manual button the boiler can be set to
operate in one of two operating modes, domestic hot
water only (summer mode) or domestic hot water and
central heating (winter mode).
Domestic Hot Water Mode:
When hot water demand is requested the boiler will fire
automatically. An integral pump is then energized and hot
water from the boiler’s primary circuit is circulated through
the secondary heat exchanger, allowing the instantane-
ous transfer of heat to the incoming cold water. The
secondary heat exchanger is protected against an
internal build up of lime scale by limiting the hot water
temperature at the tap to a maximum 64°C. Hot water will
continue to flow through the tap until no longer required.
When the demand for hot water ceases the integral pump
may continue to run for a short while to dissipate any
excess heat within the boiler.
Domestic Hot Water and Central Heating
Mode:
When heating demand is requested the boiler will fire
automatically. An integral pump is then energized and hot
water from the boiler’s primary circuit is circulated around
the heating systems, pipe-work and radiators. The heat
output from the boiler is automatically adjusted by the
boiler’s internal control unit to match the heating demand.
As the water temperature of the heating system
increases the gas input to the burner decreases, conserv-
ing energy and increasing efficiency. When the demand
for heating no longer exists either the room thermostat is
satisfied or the heating period has ended, the burner will
shut down and the boiler will revert to stand-by, waiting to
respond to the next heating demand. The integral pump
may continue to run after shut down for a short while to
dissipate any excess heat within the boiler.
Important Information
Please Note. When domestic hot water is called for
during the heating mode, the boiler will automatically
revert to domestic hot water mode until the demand
for hot water ceases.
