General Description
The Ferroli 1001 is a wall mounted, room sealed, fan assisted, combination boiler for Central
Heating (C.H.) and domestic Hot Water (D.H.W.).
The boiler is of light weight construction and the heat exchanger provides Central Heating and Domestic
Hot Water from an integrally designed unit. The boiler contains its own expansion vessel for sealed systems.
The wall mounting jig contains all the isolating cocks for the water and gas supplies which can be fitted to
the wall and provided with all the necessary gas and water connections prior to the boiler being attached.
The flue can either be left hand, right hand or rear. There are three flue lengths available and they are 0.75
metres (for wall thickness up to 565 mm), 2 metres (for wall thickness up to 1815 mm) and 3 metres (for wall
thickness) up to 2815 mm these wall thicknesses assume a rear flue outlet. For side outlet the effective wall
thickness for each flue length is reduced by 91 mm plus the distance of the appliance from the side wall. The
Central Heating and the Domestic Hot Water temperature is controlled by the Honeywell Modureg valve
in conjunction with the P.C.B. The boiler is fitted with its own Central Heating pump. The pump is switched
ON/OFF by the time clock and/or a 24 Volt room thermostat. The pump circuit also has a 6 minute over-run
time. There is a Domestic Hot Water flow switch fitted and when there is a demand for Domestic Hot
Water (flow of more than 0.5 gallon/minute, 2.5 litre/minute) the Central Heating pump is switched off
making available the maximum output of the gas burner for Domestic Hot Water. On the P.C.B. the output
for Central Heating can be set. However, this is not required for the majority of installations as the boiler will
automatically adjust its output to the system demand-AUTO-MISER control. This does not influence the
maximum output for domestic hot water. At the factory the central heating output is pre-set to maximum. The
appliance is not suitable for external installation.
