Important Installation Points; General Requirements - Heatrae Sadia Multipoint 75 Fitting Instructions And User Manual

1.0 IMPORTANT INSTALLATION POINTS

1.1 The Multipoint unvented water heater is factory fitted with two
Temperature/Pressure Relief Valves which must not be removed, blocked
or restricted in any way.
1.2 Expansion MUST be accommodated within the system. The Multipoint
75/100 incorporates an expansion vessel and check valve for this
purpose.
1.3 The Multipoint water heater must be installed by a competent installer in
accordance with Building Regulation G3 (England and Wales), Technical
Standard P3 (Scotland) or Building Regulation P5 (Northern Ireland).
FAILURE TO PROVIDE ADEQUATE TEMPERATURE AND PRESSURE
RELIEF WILL INVALIDATE ANY GUARANTEE AND LEAD TO A
DANGEROUS INSTALLATION.
WARNING: IF WATER FLOWS FREELY FROM THE PRESSURE
RELIEF VALVE OR THE TEMPERATURE/PRESSURE RELIEF
VALVES, THE ELECTRICITY SUPPLY MUST BE SWITCHED OFF
IMMEDIATELY. CONTACT THE HEATRAE SADIA SERVICE TEAM
(TEL: 01603 420330) OR AN APPROVED INSTALLER.
