1.0 INTRODUCTION
The Lochinvar CP-M+™ range is a wall hung gas-fired condensing boiler. The equipment comprises of stainless steel
radial burner assembly and heat exchanger that permits fully condensing operation.
The burner is initiated by a full electronic ignition sequence control that incorporates a spark ignition and a flame
rectification device for supervision of the flame.
The output from the boiler is regulated by a variable speed combustion fan and gas/air ratio controls to maintain the correct
combustion at all levels of modulation. This configuration allows modulation down to 25% of the rated output.
This equipment is intended for use on Group H Natural Gas (2
nd
Family) and LPG propane (3
rd
Family). The information
relating to propane firing is to be found in Section 15: LPG FUEL. This equipment MUST NOT use gas other than that for
which it has been designed and adjusted.
This equipment must be installed by a competent person, registered with a H.S.E. approved body. All installations must
conform to the relevant Gas Safety and Building Regulations. Health & Safety requirements must also be taken into
account when installing any equipment. Failure to comply with the above may lead to prosecution.
If the equipment is to be connected to an unvented (pressurised) system, care must be taken to ensure all extra safety
requirements are satisfied should a high or low-pressure condition occur in the system.
The equipment is designed for direct connection to a flue system.

4.0 GENERAL REQUIREMENTS
The Lochinvar CP-M+™ 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. PLEASE read the instructions fully before
installing or using the appliance.
4.1 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

certainly result in an unsatisfactory installation:
