The following information is a step-
by-step guide to the installation and
operation of the Grant Solar
Thermal system.
1.1 Product Description
The Grant Solar Thermal system uses
flat plate solar collectors that can be
fitted in either a ‘portrait’ or ‘landscape’
configuration and offers three different
mounting methods – ‘On-roof’, ‘In-roof’
and ‘Flat-roof’.
The ‘On-roof’ and ‘In-roof’ mounting
kits are designed for use on roof slopes
of between 20° and 65° and must be
installed in accordance with these
instructions.
The ‘Flat-roof’ mounting kit can be
used on any flat surface capable of
carrying the weight of the collectors
and any dead weighting used.
In-Roof Systems only:
A waterproof membrane must be used
on all roofs. On older roofs the sarking
felt is acceptable but if this is not
present, then a breathable waterproof
membrane must be fitted and it should
end at the eaves (roof guttering).
Short term damp can occur beneath
the roof covering (tiles or slates) on roof
slopes of less than 20° or greater than
65°, or where there are long rafters or
joined roofs, as a result of extreme
weather conditions (e.g. driving rain,
snow covering or ice formation). This
can be avoided by using additional
wedge section sealing strips. However,
adequate ventilation of the roof must
still be provided.
Installation kits for ‘On-roof’ installations
are supplied with roof anchors to suit
the type of roof covering concerned –
i.e. profile tiles, flat tiles or slates. This
must be specified when the kit is
ordered. Before commencing
installation check that the roof anchors
supplied are correct for the roof type. If
the height of profile tiles is particularly
high a special adjustable height roof
anchor is available. Contact Grant for
details.
If necessary, the installation can be
modified to suit the site conditions.
However, any changes must be
approved by Grant and must meet
Building Regulations, codes of practice,
and any relevant local bylaws and
regulations in force at the time. Failure
to comply with this will invalidate the
product warranty.
1.2 Package Contents
Solar collectors, fixing components and
other system accessories must be
handled with care during storage and
transport. If the packaging is damaged
during transit this must be immediately
reported to the supplier/delivery driver.
Before starting installation check the kit
supplied contains all the required
components. Refer to Section 2.1.
All packing materials must be disposed
of appropriately after installation.
1.3 Format of installation
instructions
These instructions describe the
installation of collectors in both the
‘portrait’ and ‘landscape’ format using
all three mounting types – ‘On-roof’,
‘Flat roof’ and ‘In-roof’. This is covered
in Sections 4, 5 and 6 respectively.
The actual fitting of the collectors and
the connection to the hydraulic solar
circuit is identical for all the above
mentioned mounting options, and is
covered in Sections 7 and 8
respectively.
1.4 Safety Instructions and
Symbols
When installing the system, take note of
the safety instructions in this document.
The symbols used in the text are
explained below:

to a potential hazard!
Note:
This symbol indicates useful
information or a general note.
1.5 Safekeeping of the
Installation Instructions
These Installation & User Instructions
must be handed over to the
householder on completion of the
installation. They should be kept for
future reference as necessary.
1.6 Installation
Installation must be carried out by a
competent installer in compliance with
all current local planning requirements,
Building Regulations, codes of practice,
Health and safety legislation, and any
relevant local bylaws and regulations in
force at the time.
All electrical installation work must be
carried out by a qualified electrician. All
wiring and earth bonding must comply
with current IEE wiring regulations.
In-roof and On-roof installations only:
When installed, both the In-roof and
On-roof systems can experience uplift
due to the wind. When installing either
system ensure that the collectors are
installed no less that THREE tiles from
any roof edge.
Important:
All system pipe connections must
use compression fittings with
brass olives. Soft soldered joints
must NOT be used on the solar
primary circuit.
Plastic pipe must NOT be used
for any part of the solar primary
circuit.
All internal solar primary system
pipework should be insulated
using suitable high temperature
resistant pipe insulation.
