Installation Requirements - Potterton Envoy System 30 Installation & Service Instructions Manual

1. Installation Requirements - Page 5
General Information
Prior to installation the boiler should be stored as
directed on the carton and in a dry place. Both the user
and manufacturer rely heavily on the installer, whose job
it is to install the boiler and connect it to a correctly
designed heating system. Acquaint yourself with the
British Standards concerning installation requirements. If
you need advice on any points, Potterton Myson's
Service Operations will be pleased to help
(see back page).
Samples of the Envoy System Boilers have been
examined by Gastec, a Netherlands Notified Body. The
range is certified to comply with the essential
requirements of the Gas Appliance Directive
90/396/EEC, the Low Voltage Directive 72/23/EEC and
shows compliance with the Electro Magnetic
Compatibility Directive 89/336/EEC and are therefore
permitted to carry the CE mark.
It is important that no external devices e.g. flue
dampers, economisers etc, be directly connected to this
appliance unless covered by these Installation and
Service Instructions or otherwise recommended by
Potterton Myson Ltd. in writing. If in doubt please
enquire.
Any direct connection of a control device not
recommended by Potterton Myson could invalidate the
certificate and normal appliance warranty and could also
infringe the Gas Safety Regulations. Manufacturers
instructions must not be taken in any way as over-riding
statutory obligations.
Codes of Practice
The boiler must be installed in accordance with the Gas
Safety (Installation & Use) Regulations 1994 (as
amended), and the current issue of:-
I.E.E. Regulations.
Model Water Bye Laws.

Health and Safety Information for the
Installer and Service Engineer
Under the Consumer Protection Act 1987 and Section 6
of the Health and Safety at Work Act 1974, we are
required to provide information on substances
hazardous to health. Small quantities of adhesives and
sealants used in the product are cured and present no
known hazards. The following substances are also
present.
Supplied By www.heating spares.co Tel. 0161 620 6677
Insulation and Seals
Material - Ceramic Fibre. Alumino - Silicone Fibre.
Description - Boards, Ropes, Gaskets.
Known Hazards - Some people can suffer reddening
and itching of the skin. Fibre entry into the eye will cause
foreign body irritation. Irritation to respiratory tract.
Precautions - People with a history of skin complaints
may be particularly susceptible to irritation. High dust
levels are only likely to arise following harsh abrasion.
In general, normal handling and use will not present
discomfort, follow good hygiene practices, wash hands
before consuming food, drinking or using the toilet.
First Aid - Medical attention must be sought following
eye contact or prolonged reddening of the skin.
Electricity Supply
A 230 volts ~ 50Hz, single phase electricity supply fused
to 3A, must be provided in accordance with the latest
edition of the IEE Wiring Regulations and any other local
regulations that apply. The current rating of the wiring to
the boiler must exceed 3 A and have a cross sectional
area of at least 0.75mm in accordance with BS 6500,
Table 16.
The supply to the boiler and its associated equipment
should be controlled by an exclusive 3A fused double
pole switch (having at least 3mm contact separation in
both poles) so that complete isolation from the supply
can be achieved to enable servicing work to be carried
out in safety.
Gas Supply
A gas supply pressure of 20mbar is required at the inlet
of the appliance. Performance data is based on use of
reference gas G20. The meter and supply pipes must be
capable of delivering this quantity of gas in addition to
the demand from any other appliances in the house and
must be governed at the meter.
Condensate Drain
The condensate outlet on the boiler is designed to
accept 21.5mm (¾") plastic overflow pipe, which if
possible should discharge into the household drainage
system and have an internal termination. If this is not
practical, discharge into an outside gully or soak away is
acceptable. To avoid blockage of this pipe due to
freezing it should be routed internally where possible
and have sufficient fall over its entire length to dispose
of condensate quickly. See British Gas 'Guidance Notes
for the Installation of Domestic Gas Condensing Boilers'.
