The Compact A comprises a range of high-efficiency
combination boilers with outputs to DHW of 25kW - 29kW -
31,60kW. These appliances – by design – incorporate electronic
ignition, circulating pump, expansion vessel, safety valve,
pressure gauge and automatic by-pass.
The Compact A range is produced as room sealed, category
II2H3P appliances, suitable for internal wall mounting
applications only. Each appliance is provided with a fan powered
flue outlet with an annular co-axial combustion air intake that
can be rotated – horizontally – through 360 degrees for various
horizontal or vertical applications. The Compact A can also be
used with the Vokèra twin flue system.
The Compact A is approved for use with C13 & C33 type flue
applications.
These appliances are designed for use with a sealed system
only; consequently they are not intended for use on open
vented systems.
Compact A boiler complies with basic requirements of the
following Regulation (EU) 2016/426; Yield directive: Article
7(2) and Annex III of directive 92/42/EEC; Electromagnetic
compatibility directive 2014/30/EU; Low-voltage directive
2014/35/EU; Directive 2009/125/EC Ecodesign for energy-
using appliances; Regulation (EU) 2017/1369 Energy labeling;
Delegated Regulation (EU) No. 811/2013; Delegated Regulation
(EU) No. 813/2013; Delegated Regulation (EU) No. 814/2013.
This booklet is an integral part of the appliance. It is therefore

customer services.
At the end of its life, the product should be not be
disposed of as solid urban waste, but rather it should be
handed over to a differentiated waste collection centre.
