GENERAL REQUIREMENTS 

 
The Lochinvar Herald condensing boiler has been designed to operate trouble free for many years.  These instructions 
should be followed closely to obtain the maximum usage and efficiency of the equipment. 

 

READ AND UNDERSTAND THE INSTRUCTIONS 

Read and fully understand all instructions before attempting to operate maintain or install the 
unit. 

 

   

6.1

 

RELATED DOCUMENTS 

 

It is law that all gas appliances are installed by competent persons, in accordance with The Gas Safety (Installation and 
Use) Regulations 1998.  Failure to install appliances correctly could lead to prosecution.  It is in your own interest, and 

that of safety, to ensure that this law is complied with. 
 
The installation of the equipment MUST be in accordance with the relevant requirements of the Gas Safety Regulations, 

Building Regulations, I.E.E. Regulations and the bylaws of the local water undertaking.  The installation should also be 
in accordance with any relevant requirements of the local gas distributor and local authority. 

 
In addition, the installation should follow the relevant guidance offered in the following documents.  It is not practical to 
list all relevant information but emphasis is placed on the following documents, as failure to comply with the guidance 

given will almost certainly result in an unsatisfactory installation:
