NOVA® Chimney System

The NOVA® family of products has been specifically designed to meet the requirements for multi-functional applications serving a variety of fuels. Whether serving a traditional negative draught appliance or a modern high efficiency condensing appliance, the NOVA® product offers the ideal solution. With a wide range of components together with a multi-barb twist-lock jointing system, NOVA® offers the ultimate in ease of installation, quality and functionality. NOVA® is a CE approved product and has been tested to the requirements of BS EN 1856-1.

NOVA® is a prefabricated, factory made twin-wall insulated stainless steel system chimney. The fully welded construction combined with a high performance / high density insulating medium, provides the optimum level of performance required for today’s modern high efficiency combustion equipment, as well as being suitable for the more traditional oil, gas and solid fuel fired appliance. The construction provides a high thermal resistance which ensures rapid stabilisation of the flue gas temperature and draught, whilst maintaining a relatively low temperature on the external surface of the chimney.

NOVA® is designed for internal and external applications and is suitable for negative pressure applications. When used with a seal and where the flue gas temperature does not exceed 200°C, the NOVA® product is suitable for wet and positive pressure applications up to 200Pa (P1).

NOVA® utilises a multi-barb quick lock jointing system to secure each joint. The number of barbs depends on the product diameter, and in each case the components are secured by locating the barbs with a twist of each section. A locking band must then be used at each joint. The joint design facilitates a maximum unsupported height above the last support of up to 3.0 metres (2.0 metres for 100ID), subject to the design considerations detailed within the Installation Instructions and on page 30 of this brochure.

NOVA® is manufactured from a high grade 316L (1.4404 : X2CrNiMo 17-12-2) stainless steel liner and a 304 (1.4301 : X5CrNiMo 18-10-2) outer case. The product utilises a high performance mineral wool which is auger filled into a 25mm annulus between the inner and outer, offering rapid stabilisation of draught and excellent thermal performance. The unique joint design allows the inner liner to freely expand and contract throughout the system as the flue gas temperature varies, alleviating the need for additional expansion components.
