Installation and maintenance manual ecoMAX 665
Important!
When tightening or loosening screwed connec-
tions always use suitable open-ended span-
ners (not pipe wrenches or extensions etc.).
Incorrect use and/or unsuitable tools can lead
to damage being caused (e.g. gas or water
leakage)! Preliminary remarks: This appliance
should only be installed in conjunction with a
Vaillant flue system. Install the flue system
as detailed in the separate flue installation
instructions supplied with this boiler.
Boiler location
The location chosen for the boiler must permit the provi-
sion of a satisfactory flue termination. The location must
also provide adequate space for servicing and air circu-
lation around the boiler. The boiler may be installed in
any room, although particular attention is drawn to the
requirements of BS7671 (IEE Regulations), the electrical
provisions of the Building Regulations (Scotland) and in
IE the current edition of IS 813 and the current ETCI
rules, in respect of the installation of a boiler in
a room containing a bath or shower.
Note!
Where a room sealed boiler is installed in a
room containing a bath or shower, any electrical
switch or boiler control utilising mains elec-
tricity should be so situated that it cannot be
touched by a person using the bath or shower.
Where the installation of the boiler will be in an unusual
location, special procedures may be necessary and
BS 5546 and BS 6798 give detailed guidance on this
aspect. The boiler must be mounted on a flat, vertical
wall, which must be sufficiently robust to take the
weight of the boiler. The boiler may be installed on a
combustible wall, subject to the requirements of the
Local Authorities and Building Regulations. A compart-
ment used to enclose the boiler must be designed and
constructed specifically for this purpose. (An existing
cupboard or compartment may be used provided that it
is modified for the purpose).
Details of essential features of cupboard/compartment
design including airing cupboard installations are given
in BS 6891. In IE the current edition of IS 813. If the boil-
er is to be fitted in a timber framed building, it should be
fitted in accordance with Institute of Gas Engineers
Publication IGE/UP/7/1998 “Guide for Gas Installation in
Timber Framed Housing”.
Gas Supply
The gas supplier should ensure the availability of an
adequate supply of gas. A gas meter may only be con-
nected to the service pipe by the supplier of gas or their
contractor. An existing meter should be checked to
ensure that it is capable of passing the rate of gas sup-
ply required. Installation pipes should be fitted in accord-
ance with BS 6891. Pipework from the meter to the boil-
er must be of an adequate size. Do not use pipes of a
smaller size than the boiler gas connection (15 mm,
22 mm for 837/637). The complete installation must be
tested for soundness and purged as described in BS
6891.
