4.4 Installing the Boiler
1. 1. If the boiler is to be fitted against
the wall, prepare the wall to accept
the heating system pipework. To
mark the wall for drilling, refer
to Section 2.6 for the positions
of the pipework openings in the
enclosure sides.
If the boiler is to be installed ‘free
standing’ (i.e. away from a wall)
and the pipework run underground,
push out the ‘knock-outs’ to open
the required pipe openings in the
base of the boiler enclosure. Using
a sharp knife, cut through the
polystyrene in the base, around
the edge of the holes, to allow the
flow and return pipes to enter the
enclosure.
2. The electrical supply to the boiler
should be routed through the wall
in a suitable conduit, such that it
enters the boiler enclosure via one
of the unused pipework openings.
The cable can be routed to the
front of the boiler, for connection to
the boiler control panel, either over
the top or beneath the boiler heat
exchanger. Heat resistant PVC
cable, of at least 1.0 mm² cross
section should be used within the
boiler enclosure.
3. The oil supply line should be
installed up to the position of the
boiler. Refer to Section 3.1 for
details. The final connection into
the boiler enclosure can be made
with 10 mm soft copper, routed
along the base of the enclosure
(either between the enclosure and
wall or in front of the enclosure)
to enter through one of the holes
located in the bottom edge side
panel, at the front (burner) end.
4.5 Regulations Compliance
Installation of a Grant VORTEX Eco
boiler must be in accordance with the
following recommendations:
• Building Regulations for England
and Wales, and the Building
Standards for Scotland issued by
the Department of the Environment
and any local Byelaws which you
must check with the local authority
for the area.
• Model and local Water Undertaking
Byelaws.
• Applicable Control of Pollution
Regulations.
• The following OFTEC
requirements:
• OFS T100 Polythene oil
storage tanks for distillate
fuels.
• OFS T200 Fuel oil storage
tanks and tank bunds for use
with distillate fuels, lubrication
oils and waste oils.
Further information may be obtained
from the OFTEC Technical Book 3
(Installation requirements for oil storage
tanks) and OFTEC Technical Book 4
(Installation requirements for oil fired
boilers).
The installation should also be in
accordance with the latest edition of
the following British Standard Codes of
Practice:-
• BS 715 Metal flue pipes, fittings,
terminals and accessories.
• BS 799:5 Oil storage tanks.
• BS 1181 Clay flue linings and flue
terminals.
• BS EN 1856-1:2009 Chimneys.
Requirements for metal chimneys.
System chimney products.
• BS 5449 Forced circulation hot
water systems.
• BS 7593 Code of Practice for
treatment of water in heating
systems.
• BS 7671 Requirements for
electrical installations, IET Wiring
Regulations.
4.6 Completion
Please ensure that the OFTEC CD/10
installation completion report (provided
with the boiler) is completed in full.
Leave the top copy with the User.
Retain the carbon copy.
Ensure that the User Information pack
(supplied with the boiler) is handed over
to the Householder.
4.7 Before you Commission
To avoid the danger of dirt and foreign
matter entering the boiler the complete
heating system should be thoroughly
flushed out - before the boiler is
connected and then again after the
system has been heated and is still hot.
This is especially important where the
boiler is used on an old system.
For optimum performance after
installation, this boiler and its
associated heating system must
be flushed in accordance with the
guidelines given in BS 7593:2006
‘Treatment of water in domestic hot
water central heating systems’.
This must involve the use of a
proprietary cleaner, such as
BetzDearborn’s Sentinel X300 or X400,
or Fernox Restorer. Full instructions are
supplied with the products, but for more
details of BetzDearborn’s products,

solutions.net and for more details of
Fernox products view the website www.
