PLUMBING
Diagrams illustrate the basic principles of water sys-
tems and are not to be regarded as working draw-
ings.
NOTE: We strongly advise the use of pipe lagging
and also the use of a frost thermostat if the installa-
tion is likely to be exposed to situations where the
temperatures will drop to a level consistent with
frost.
Central Heating and Indirect Domestic Hot
Water.
Recommended indirect cylinder 135 litres, depend-
ing on domestic requirements with a 28mm flow and
return pipes not exceeding 7.8m each in length.
Cylinder and pipework should be lagged to minimise
heat losses.
HEATING SYSTEM
The system must include a gravity circuit with
expansion pipe, open to the atmosphere. The cen-
tral heating must be pump-driven as with other types
of boilers. The primary air valve controls the heating
rate of the boiler, Closed = minimum, Open = maxi-
mum output. (See operating instructions).
BOILER OUTPUT (Central Heating)
High output cannot be maintained unless fuel is
being burned at a rate of 2.7 kg. per hour of coal.
When burning wood or peat, reduced outputs
will apply because of the lower calorific value of
the fuels.
GRAVITY CIRCUIT
The gravity circuit consists of a domestic hot water
tank of 135 litres Indirect Cylinder for central Heating
units and Direct Cylinder for Domestic Hot Water
Unit fixed in an upright position, recommended for
hot water storage and it should be connected to the
boiler by 28mm diameter flow and return piping. The
pipes should not exceed 7.8m each in length and
anything in excess of 4.6m must be fully lagged.
The shorter the run of pipe work the more effective
the water heating efficiency and to this end, the
cylinder should be fully lagged. In the interest of
safety do not have any valves on this circuit.
HEATING
Care should be taken to ensure that the heating
installation is correctly installed and that it complies
with all relevant codes of practice. If this appliance
is being connected to an existing system, it is
strongly recommended to check the following.
(a) That the pipework is adequately insulated
(where applicable).
(b) Check all controls e.g. pump, pipe thermo-
stat etc, are operating satisfactorily and
are compatible with the requirements of the
cooker.
(c) Cleanse the system and add suitable
inhibitor.
Only competent personnel should be employed to
carry out your heating installation.
PIPE FITTINGS
Materials used for installation work should be fire
resistant, sound and should conform to the current
editions of the following or their equivalent:
1. Ferrous Materials
B.S. 1387: Steel Tubes
B.S. 4127: Stainless Steel Tubes
B.S. 1740: Steel Pipe Fittings
B. S. 6956: Jointing Materials
2. Non-Ferrous Materials
EN 29453: Soft Solder Alloys
B.S. 864: Compression Tube Fittings
B.S. 2871 & EN 1057: Copper & Copper
Alloys.
WATER CIRCUIT TEMPERATURE
The return water temperature must be maintained at
not less than 50º C so as to avoid condensation on
the boiler and return piping. Fitting a pipe thermo-
stat to the return from the gravity circuit and wiring it
into the pump control will ensure than no cold water
will be returned from the central heating circuit
before the water from the gravity circuit has warmed
up the common return pipe and boiler. If this is not
sufficient to keep the boiler temperatures above the
