Health & Safety Document No. 635.
(The electrical at work regulations 1989). The manufacturer’s
notes must NOT be taken, in any way, as overriding statutory
obligations.
IMPORTANT

appliance warranty.
INTRODUCTION
The Ideal Heat Interface Units (HIUs) are designed for use in
conjunction with an external central plant heat source. Examples
of central plant systems include centralised boilers, district heating
or central energy systems using renewable energy sources.
Detailed recommendations are contained in the following British
Standard Codes of Practice:
BSEN.12828:2003 Heating Systems in buildings:
Design for water based systems.
BSEN.12831:2003 Heating Systems in buildings: Method
for calculation of the design heat load.
BSEN.13831 Specification for: Expansion vessels
using an internal diaphragm, for sealed
hot water heating systems.
BSEN.14336:2004 Heating Systems in buildings:
Installation and commissioning of
water based heating systems.
The appliance is suitable only for installation in GB and IE and
should be installed in accordance with the rules in force.
The appropriate Building Regulations either The Building
Regulations, The Building Regulations (Scotland), Building
Regulations (Northern Ireland).
The Water Fittings Regulations or Water byelaws in Scotland.
The Current I.E.E. Wiring Regulations. In IE, the installation must
be carried out by a Competent Person and installed in accordance
with the current edition of I.S.813 and the current Building
Regulations and reference should be made to the current ETCI
rules for electrical installation. Where no specific instructions are
given, reference should be made to the relevant British Standard
Code of Practice.
