The Alpha Pro Tec range are wall mounted high efficiency condensing, fan assisted system boilers. The burner is lit 

electronically and the heat output is controlled by a modulating fan and gas valve.
These are system boilers providing heating only for sealed central heating systems. However, they may be used with an 

open central heating system if required - refer to Section 3.8.
The boilers are supplied with type B23 flue configuration (open chamber and forced draught) but can be changed to type C 

(room sealed) by using a kit.
The boilers are fitted with a pump, 4 bar safety valve and pressure gauge fully assembled and tested. They are designed for 

use with a fully pumped, sealed and pressurised central heating system. If used with an open system refer to Section 3.8.

The boilers can be supplied for use with Natural gas or Propane Gas (LPG).

Note: 

There are a number of additional controls and accessories available for use with the boilers to enable cascade and zone 

installations to be used - See Section 11. Further information is available from Alpha Therm Ltd.

IMPORTANT

It is the law that all gas appliances are installed by a competent person, ie Gas Safe registered personnel, in accordance 

with the following recommendations:-
Current Gas Safety (Installation and Use) Regulations
All current Building Regulations issued by the Department of the Environment, i.e. Approved Document L26.
Building Standards (Scotland) (Consolidation) Regulations issued by the Scottish Development Department
UK Water Regulations/Byelaws (Scotland)
Health & Safety Document No. 635 (The Electricity At Work Regulations 1989)
The installation should also be in accordance with the following British Standard Codes of Practice:-

BS 5440-1: 2008 ........................Flueing and Ventilation Requirements 
BS 5440-2: 2009 ........................Installation and Maintenance of Flues and Ventilation
BS 5546: 2010 ...........................Specification for Water Heating Appliances
BS 6644: 2011 ...........................Specification for Installation gas fired boilers 70 kW – 1.8 MW
BS 6798: 2009 ...........................Specification for Installation gas fired boilers up to 70 kW
BS 6891: 2005 + A2: 2008 .........Installation of low pressure Gas Pipework

IGE/UP/10 .................................Installation of Flued gas appliances
IGEM/UP/16 ..............................Design for natural gas installations
IGE/UP/1 and 1A .......................Strength Testing and tightness testing Natural Gas Installations
Reference should also be made to any other standards and requirements relating to the installation depending on the location 
and use.
Reference should be made to DEFRA document 'Guide to condensing boiler installation assessment procedures for dwellings'.
If installation is in a timber framed building, refer to the Institute of Gas Engineers document IGE/UP/7.
This appliance meets the requirements of IPX5D, ie degree of protection against moisture.
This appliance contains no asbestos and no substances have been used in the construction process that contravene the 
COSHH Regulations (Control of Substances Hazardous to Health).

Failure to install this appliance correctly could lead to prosecution. It is in your own interest and that of safety to ensure that 

the law is complied with.
Manufacturer's instructions must 

NOT 

be taken in anyway as over-riding statutory obligations.

Notes: 

1.  Ensure that the Benchmark Checklist has been completed after the boiler has been installed and commissioned.

 

2.  It is the law that all domestic boiler installations are registered by the installer through the Gas Safe Notification 

Scheme.

Propane Gas (LPG) - 

In addition to the regulations and requirements stated, the boiler 

must be 

installed in accordance with 

BS 5482:1 - The Installation of Propane Burning Appliances in Permanent Dwellings.
