the different regulations for each country are separately described.
These instructions are intended for the use by Gas Safe Register approved contractors or

of A.O. Smith boilers. It is advisable to read these instructions thoroughly, well in advance
of installation. Separate instructions for use are supplied with the boiler for users of A.O.
Smith central heating boilers. A.O. Smith is not liable for the consequences of mistakes or
shortcomings which have found their way into the installation instructions or user’s manual.
Further, A.O. Smith reserves the right to alter its products without prior notification.
When delivering the unit, give the customer clear instructions concerning its use;
present the customer with the user’s manual.
Each unit is fitted with an identification plate. Consult the details on this plate to verify
whether the unit is compliant with its intended location, e.g.: gas type, power source and
exhaust classification.
