Warning
All of the basic criteria must be satisfied
prior to commencing installation and
commissioning, additionally, the Cabinet
Heater must be positioned and installed so
as to comply with all the relevant standards
and guide lines (
see section 9.0) , as well as
meeting National and Local Fire Regulations
and Insurance criteria, especially if it is
proposed that the heater is to be installed
within a special risk area (e.g. proximity to
where petrol engined vehicles are stored or
parked, where cellulose spraying takes
place, where woodworking machinery is
operated, etc,).
Indirect fired heaters must not be located in
hazardous areas, however, it is permissible
for the heater to supply air to such areas.
The heater must not be installed within an
environment where there is a high
concentration of chlorides, fluorides, salts, or
other aggressive or volatile chemicals/
compounds. Nor should the heater be
positioned where high winds or draughts
could adversely affect the burner.
The location chosen for the heater must
allow for the fitting of an effective flue
system.
The location must also allow for adequate
clearance for the air supply, return air
circulation, oil supply, electrical supply,
whilst also providing good and safe working
access.
The heater must be installed on a flat and
level surface made from non-combustible
material, which is sufficiently robust to
withstand the weight of the heater and any
ancillary equipment. Any combustible
material adjacent to the heater or flue
system must be so placed or shielded so
that its surface temperature does not
exceed 65
°
C.
In areas where it is proposed that more than
one heater is to be installed, a general
scheme of circulation should be drawn up
and maintained, thereby offering the best
heat distribution.
All Harry Taylor Heaters are fitted with a
pressure relief facility, this is incorporated
into the design of the flue gas exit duct.
Care should therefore be taken in siting
service connections and controls well away
from the pressure relief vent.
Warning
Under no circumstances must the pressure
relief be restricted, blocked, or have the free
exit of exhaust gas impaired or re-directed.
2.1 Fuel supply - general
The Harry Taylor range of oil fired cabinet
heaters are all manufactured and pre-set for
use with 35 second gas oil delivered to the
burner via a suitable piped system from the
oil storage tank.
Galvanised or plastic pipe work and
fittings must not be used. (see BS 5410
Part 1 1997)
The constraints of the application will, to a
large extent, determine whether it is
preferable to use a single pipe gravity feed
system, or whether the two pipe pumped
system is more appropriate.
Where more than one appliance is to share
a common supply it will be necessary to use
a pressurised ring main system.
All pipe work must be constructed and
installed so that it does not permit the
ingress of air.
The construction, size, and position of the oil
storage tank must take account of the
current regulations, as well as suiting the
requirements of the installation.
Please refer to figures 2 - 8 for additional
information.
Caution
On pumped systems always check that the
pump is correctly set up prior to running, and
always ensure that valves are open allowing
a free flow of oil through the system.
