GAS SAFETY (INSTALLATION AND USE)
REGULATIONS 1994.
The appliance must be installed and serviced by a
competent person, in accordance with the above
Regulations.
In the UK 'Corgi' Registered Installers (including the
Regions of British Gas) undertake the work to a safe and
satisfactory standard.
Failure to install appliances correctly could lead to
prosecution.
It is in your own interest, and that of safety, to ensure that
the Regulations are complied with.
Samples of the Puma Flowsure+ gas boilers have been
examined by Gastec, a Netherlands Notified Body. The
range is certified to comply with the essential requirements
of the Gas Appliance Directive 90/396/EEC, the Low
Voltage Directive 72/23/EEC and shows compliance with
the Electro Magnetic Compatibility Directive 89/336/EEC
and are therefore permitted to carry the CE Mark.
The appliance has been tested and approved by the WRc
as meeting the requirements of G3 and L of the Building
regulations and water Bylaws Scheme - Approved
Products.
The Puma Flowsure+ boilers are fully automatic, wall
mounted, fan assisted, room sealed storage combination
boilers, designed to operate on Natural Gas only.
The Puma Flowsure+ adjusts automatically to provide
central heating outputs between 24 kW (81,880 Btu/h) and
10.4 kW (35,480 Btu/h) to suit the system requirements.
Domestic hot water has priority over the central heating
system and is generated within the tank.
The range of horizontal and vertical flue systems with small
terminals simplify siting and installation.
The combination boilers are designed for use with fully
pumped sealed system only.
They are supplied fully tested and assembled with a
circulating pump, diverter valve, pressure gauge, pressure
relief valve, and expansion vessels.
Fig. 1 shows the main components of the boiler assembly.
A central heating switch controls the choice of service
between central heating/hot water and hot water only.
The boiler water flow system is shown in Fig. 2.
4 Introduction
With the central heating switch set to 'Off' and the boiler
switch set to 'On', the combination boiler fires only when
hot water is drawn off and occasionally to maintain the
temperature of the stored hot water.
With the central heating switch set to 'Timed' the boiler will
operate the central heating for the time periods set on the
optional internal or externally mounted timeclocks.
If 'Constant' is selected the boiler will operate continuously.
The temperature of the central heating can be changed by
adjusting the knob on the front of the appliance.
The domestic hot water is supplied at a pre-set
temperature determined by the d.h.w mixing valve setting.
If domestic hot water is drawn off while the central heating
is running the combination boiler will automatically transfer
the boiler heat output to the domestic hot water supply.
At the minimum hot water draw-off rate the maximum
temperature is limited to 60°C by the mixing valve in the
tank. This temperature can be changed by adjusting the
mixing valve knob.
The combination boiler has a white front case which can be
removed for servicing.
Data plates are positioned on the front of the air box door
and a boiler serial badge is on the underside of the air box.
A duplicate serial badge is positioned on the underside of
the case base for customer reference.
A data badge is also located on the tank.
