The
Halstead Finest Platinum
and
Finest Platinum Pr
opane
ar
e fully
automatic, wall mounted, fan-assisted, balanced flue gas combination
appliance for use with natural gas (G20) and LPG (G31). They incorporate a
microprocessor based, fully modulating gas control system with direct burner
ignition. The appliances incorporate a domestic hot water (DHW) pre-heat
feature which can automatically adjust to the user’s habitual requirements. Thus
during long stand still periods, eg overnight, no pre-heat is provided.
The
Halstead Finest Platinum
featur
es an attractive white stove enamelled
casing with an inset control panel. The flue elbow and air ducts are also white
stove enamelled to give a clean, attractive appearance to the Installation.
Central heating (CH) output is fully modulating with a range 14.6 kW
(49,747 Btu/h) to 24.9 kW (85,000 Btu/h). DHW output is also fully
modulating with a maximum of 32.2 kW (110,000 Btu/h) - nat gas, 29.3 kW
(100,000 Btu/h) - propane. The appliance always gives priority to DHW
demand.
The appliances are supplied with a standard telescopic concentric air and flue
duct system suitable for flue lengths of up to 820 mm (32in). The duct
assembly is connected to the boiler via a turret which can exit the boiler in any
horizontal direction. Extension ducts may be fitted in accordance with and up
to the maximum dimensions stated in these instructions.
A vertical outlet kit is also available for installations where an outside wall is
not accessible and it is desired to fit the kit ‘through the roof’. Installation using
the standard flue kit is described in the main text of these instructions and
supplementary instructions at the rear of this booklet describe installation
involving the vertical outlet kit.
NO OTHER FLUE KITS OR EXTENSIONS
MAY BE USED WITH THESE APPLIANCES.
The appliances can be installed fr
om inside the room without access to the
external wall provided that a wall liner is fitted and that the wall thickness is
less than 0.5 m (19 in). The wall liner is available as an optional extra. See
section 4 for further details. (Note: If the vertical outlet kit is to be used, access
to the roof is necessary).
The appliances are designed for use with sealed primary water systems and
incorporates a circulating pump, diverter valve assembly, pressure gauge, flow
switch, safety valve and system expansion vessel. A separate DHW expansion
vessel is not required. Isolation valves are fitted to the service connections and
an automatic heating by-pass is fitted to maintain an adequate flow rate
through the boiler.
If thermostatic radiator valves are installed it is recommended that one radiator
is fitted with lockshield valves (normally in the bathroom) to allow pump
overrun circulation. Internal frost protection is fitted as standard equipment.
The boiler may be used with any certified mains voltage room thermostat. An
electro-mechanical 24 hour time clock is fitted as standard.
NOTE: British Standar
d BS7593: 1992 stresses the importance of
cleansing and flushing of the system to ensure it continues to run
efficiently with the minimum of maintenance necessary. Halstead
Boilers fully support this professional approach and recommend
that the system is cleansed with an effective chemical cleanser
and protected long term with a suitable inhibitor. Such products
are available from Fernox and Sentinal.
