! NOTE !
Ensure that the Plume Diverter Kit starter elbow is fully
pushed onto the external boiler ue terminal. See above.
The boiler is supplied with a ue terminal. Refer to Section 4.7 for
tting details.
As an alternative to the terminal supplied, there are three external
ue systems that can be used with the Vortex Eco External boiler,
all available from Grant UK.
PLUME DIVERTER KIT
This vertical system is availabe to purchase from Grant UK and
is intended to be retrotted to the ue terminal supplied with
the boiler, in order to terminate the ue in a more preferable or
permissable location.
GRANT GREEN SYSTEM
VERTICAL:
This vertical twin wall stainless steel insulated system replaces
the low level terminal supplied with the boiler, and may terminate
at high level or vertically as required.
HORIZONTAL:
This option allows the extension of the ue system in the
horizontal plane in order to terminate the ue in a more preferable
or permissable location.
These systems are described in this section.
9.1 AIR SUPPLY
A su󰀩cient permanent air supply to the boiler should be provided
for the following reasons:
• For proper combustion of fuel and e󰀨ective discharge of
combustion products to the open air.
• For the ventilation of any conned space in which the boiler
is installed to prevent overheating of the boiler and any
equipment in and near the boiler.
Grant external boilers draw their air supply via the ventilation
holes in recessed top edge of the front door of the boiler casing.
These ventilation holes must not be obstructed.
Further details may be obtained from BS 5410-1.
9.2 PLUME DIVERTER KIT
Should the low level ue supplied with the boiler be discovered
to cause a plume nuisance after its installation, a plume diverter
kit is available to purchase from Grant UK for the purpose of
re-directing the ue gases to a higher level (according to the
minimum clearances shown in Figure 9-5).
The plume diverter kit has been designed to be retrotted to the
low level ue supplied with the external boiler by attaching the 90°
elbow supplied with the kit directly to the boiler ue terminal.
This kit is available in two sizes, only one of which is to be used
with the Eco External boilers, product code as follows:
• GDPA90B - (maximum vertical length of 2.08m)
While every e󰀨ort has been made to make this retrot as simple
as possible for the installer, it is necessary for the installer to drill
an 8mm hole in the side of the existing ue terminal to ensure
that the condensate produced by the ue gases during normal
operation drain back into the boiler.
It is also necessary for the installer to spot drill two 3mm holes in
the existing ue terminal. With the plume diverter starter elbow
in its nal position on the existing ue terminal, use the holes in
either side of this elbow as a guide to drill the two holes in the
terminal and x the elbow to the existing terminal by driving one of
the two self-tapping screws provided into each hole.
More detailed installation details for this system can be found in
the tting instructions supplied with the kit.
Please see Figures 9-1 and 9-2 for a visual representation of the
plume diverter kit tted onto a Grant Vortex Eco External boiler.
A series of extensions and other accessories are available for use
with this kit. Please contact Grant UK for further information.
