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.

Installation Details
Gas Safety (Installation & Use) Regulations: 1994
In the interest of safety, it is the law that all gas appliances are installed by a competent person in accordance
with the above Regulations, Building Regulations/Building Standards Scotland, Codes of Practice, current
I.E.E. Regulations and the byelaws of the Local Water Undertaking. Failure to comply with the Regulations
may lead to prosecution; it is in your interest and that of safety to ensure that the law is complied with.
Important - If the boiler is to be fitted in a timber framed building it should be fitted in accordance
with the British Gas publication; Guide for Gas Installation in Timber Frame Housing: Reference DM2.
If in doubt advice must be sought from the Local Gas Region of British Gas Plc.
Location of Boiler
The installation of the
provide an adequate fixing for the boiler mounting bracket assembly. The location should be in an area where
the water pipes will not be subjected to frost conditions. In siting the combination boiler the following
limitations must be observed:
The combination boiler may be installed in any room or internal space, although particular attention
is drawn to the requirements of the current, i.e. wiring regulations and in Scotland the electrical provisions
of the building regulations applicable in Scotland, with respect to the installation of the combination boiler in
a room or internal space containing a bath or shower.
Where a room sealed appliance is installed in a room containing a bath or shower any electrical switch
or appliance control utilising mains electricity, should be so situated that it cannot be touched by a person
using the bath or shower.
Terminal Position
1001 must be on a suitable non-combustible load bearing wall which will
POSITION MINIMUM SPACING (fig. 3) mm
A Directly below an openable window, air vent, or any other ventilation opening 300
B Below gutters, soil pipes or drainpipes 75
C Below Eaves 100

Flue system
The boiler allows the flue outlet to be taken from the rear of the boiler or from either side.
A standard flue length of 0.75 metres is provided. Alternative lengths of two or three metres can be supplied (equivalent
to wall thicknesses of up to 565, 1815 and 2815 mm for rear flues and deduct 91 mm plus distance from side wall for
side outlet flues).
It is absolutely essential, to ensure that products of combustion discharging from the terminal cannot re-enter the
building, or enter any adjacent building, through ventilators, windows, doors, natural air infiltration, or forced ventilation/
air conditioning.
Gas Supply
If necessary the local Gas Region should be consulted, at the installation planning stage, in order to establish the
availability of an adequate supply of gas.
An existing service pipe must not be used without prior consultation with the Local Gas Region.
A gas meter can only be connected by the Local Gas Region, or by a Local Gas Region's Contractor.
Installation pipes should be fitted in accordance with BS6891-1988.
Appliance inlet working pressure must be 20 mbar MINIMUM.
Pipework from the meter to the combination boiler must be of an adequate size.
The boiler requires 3.3 m3/h (116 ft3/h) of natural gas.
Do not use pipes of a smaller size than the combination boiler inlet gas connection.
The complete installation must be tested for gas soundness and purged as described in BS6981-1988. All pipework
must be adequately supported. An isolating gas valve is provided and should be fitted on the manifold assembly.
Water System
Central Heating
It must be a sealed system. Detailed recommendations are given in BS6798, BS5449, BS6700 and CP342 Part. 2.
Pipework not forming part of the useful heating surface should be insulated to prevent any heat losses or possible freezing
(i.e. in roof spaces or ventilated underfloor spaces). Drain taps should be positioned at the lowest point of the system
in accessible locations to permit the whole system to be drained down. The drain taps should be in accordance with
BS2879. Copper tubing to BS2871, Part. 1 is recommended for water carrying pipework. Pipework in horizontal runs
should have a gradient where possible to facilitate the removal of air. It should be ensured that the boiler heat exchanger
is not a natural point for collecting air. A typical heating system with domestic hot water circuit is illustrated in fig. 6.
Important - A bypass must be fitted to ensure a minimum flow rate through the boiler of 6 l/min. The bypass should
be fitted as far as possible from the boiler if thermostatic radiator valves are fitted throughout.
Make up Water
Provision must be made for replacing water lost from sealed system. Reference should be made to BS6798, for
methods of filling and making up sealed systems. There must be no direct connection between the boiler's central
heating system and the mains water supply. The use of mains water to charge and pressurise the system directly,
is conditional upon the Local Water Byelaw. Again any such connection must be disconnected after use.
Domestic Hot Water
Always fit a water softener or descaler in «hard water areas». A 15 mm copper connection point on the boiler jig
bracket for attaching to the main supply is provided. The maximum domestic water pressure for the inlet supply is 10
bar (145 P.S.I.). If the cold mains supply exceeds 5 bar (72 P.S.I.), a water governor or pressure reducing valve must
be fitted by the installer into the mains supply in an inconspicuous but accessible position preferable between 3 and 5
metres (10-16 ft) before the appliance.
Such a valve must be approved by the Water Research Council.
Attention - Is drawn to the Model Water Byelaws.
Fittings manufactured from duplex (alpha-beta) brass are not acceptable for underground use and certain water
undertakings will not accept their use above ground.

7.0 ELECTRICAL INSTALLATION
Electrical installation must be carried out by a competent electrician. The appliance is to be connected to a 240 V
~ 50 Hz supply (see fig. 18). The supply fuse rating is 3A. The terminals are accessible after removing the white
base plate and single screw securing the terminal cover (see fig. 18).
7.1 Procedure
7.1.1 The supply cable must be no less than 0.75 mm (24x0.2 mm) to BS6500 table 16.
7.1.2 The earth conductor must be cut longer than the live and neutral (fig. 19).
Connect the Supply Cable to the terminal block marked 240 V ~ 50 Hz, L, N, the supply cable is to be connected as
follows:
i) Connect the brown wire to the L (live) terminal).
ii) The blue wire to the N (neutral) terminal.
iii) The green/yellow wire to the (earth) terminal.
7.1.3 Secure the cable with the cable clamp. The supply cable can be connected to the mains supply by the use of an
unswitched shuttered socket-outlet in conjunction with the 3A fused 3 pin plug both in accordance with BS 1363. This
provides complete isolation. Alternatively, a fused double pole switch having a contact separation of at least 3 mm,
in all poles and provided just for the boiler and its external controls can be used. A wiring diagram is provided on
the appliance, attached to the rear of the front panel. In addition, there is one in this manual (fig. 25). Attention is
drawn to the requirements of the current I.E.E. Regulation and in Scotland, the electrical provisions of the Building
regulations.
7.2 Room Thermostat (fig. 18) (or remote time clock connection)
7.2.1 Please note that the room thermostat, clock switch connection is 24 V. To connect mains voltage to these terminals will
seriously damage the printed circuit board. The room thermostat and clock switch connector block is situated within
the connector box. Twin core cable should be used for this connection (terminals 4 and 5).
7.2.2 If using a remote 240 Volt time clock ensure that the motor and switch connections are totally separate in the clock
and that the switch connections are independent for the 24 Volt terminals (4 and 5) on the boiler.
External controls: room stat or remote time
clock in the place of loop terminals 4 and 5.
Please note 24 V only, use only voltage free
contacts.
IMPORTANT
If 230 V is connected to terminals 4 or 5,
damage will be caused to the P.C.B.

8.7 D.H.W. Burner Pressure
The domestic hot water burner pressure is not range rateable and not adjustable but the maximum and
minimum burner pressure should be checked as follows:
a. Check electricity supply is still off.
b. Open a D.H.W. tap at high flow until the water runs cool and leave running.
c. Switch on the electricity supply.
d. The pressure should be 14 mbar -/+ 0.5 mbar.
e. Disconnect one of the wires from the «Modureg» (fig. 22), this will reduce the burner to minimum
which should read 3.0 mbar +/- 0.5 mbar. If the burner pressure is not as stated check the
inlet working pressure (fig. 22) which should be minimum 20 mbar. If that is correct, consult Ferroli.
No attempt should be made to alter D.H.W. burner pressure.
f. Switch off electrical supply and close hot tap.
g. Reconnect the wire to the «Modureg». Remove pressure gauge, tighten the test screws.
h. Replace control panel (2 screws).
i. Turn on electricity supply, open a hot tap to full flow and when the burner lights, test for gas soundness
with a leak detection fluid around the gas valve and connections including the pressure test point
screws.
9.0 SYSTEM OPERATION
Let the boiler operate normally on central heating for about 30 minutes.
I) Vent radiators.
II) Vent heat exchanger.
III) Examine all pipework for leakage.
IV) Turn on a D.H.W. tap and check that the C.H. pump stops running.
V) As the D.H.W. temperature reaches 60°C check the burner for modulation.
Switch off electricity.
Drain down the central heating system fully, when hot.
Refill the system as previously instructed. Repeat the venting.
Examine the system's water pressure and top up as necessary.
Replace the casing front panel and close the control panel cover.
