A two-wall system for condensing boilers and operating in hypertension

CHARACTERISTICS OF KP SYSTEM

This system, known also as Aerial-Combustion Coaxial Duct, can be described as highly efficient and suitable to use in extreme conditions removing wet fumes from gas or oil burning appliances. Coaxial pipes are characteristic for that system as well as it „pipe in pife” contruction. This system can be described as highly efficient and suitable to use in extreme conditions – removing wet fumes from gas or oil burning appliances. With the aim of external ductfumes are taking out of heating appliance. External chimney duct is made of stainless steel. External duct is made of acid resistant stainless steel. Additional external duct was equippedd with gaskets that provide tightness of connections an well as safety to the system users.

WHEN KP SYSTEM IS TO BE USED AND WHAT ARE IT'S ADVANTAGES

Condensate boiler is the very first and most relevant aspect that decides whether to choose that system. Condensate boilers are more and more apperciated by customers because of their safety and economy. Manufacturer declare that efficiency of boilers of that type reach about 106 per cent, what can be a little bit confusing for costumers. 106 per cent – how is it possible ? But it is very easy to explain. Condensate boilers besides taking advance of heat preduced during combustion process, recover the heat from condensate present in chimney ducts. This additional „bonus of energy) is reconized as an additional surplus. This is the basic advantage of condensate boilers-additional heat recovery and economy. The specification of such a boilers requres application of chimney system of special material parameters as well as proper structure. First of all the system must be made of stainless steel, because during the connections constitutes another relevant aspect. It should be provided by silicone gaskets. The tightness of the system is important because of following two reasons. As in every chimney system it is important that poisonous post-combustions do not get out of chimney ducts in places where it is considered as forbidden. Connection of elements should constitute a permanent barrier for condensates flowing off the walls of chimney shaft. Getting out condesates can lead to so called runs on the wall that is situated near the chimney duct, what is rather unwanted from the users point of view.

KP system was designed regarding to above mentioned aspects in such a way that it can work for years as well as preserve it's elementary functions. Stainless steel of a proper composition and high technological parameters guarantees cossosion resistance caused by acids. Thanks to applying of gaskets of proper strength the system ensures 100 per cent of it's tightness and users safety. KP system is economical because of surface it takes. Instead of twoducts we have only one that joins two functions. Economical regarding the surface and installation-that is most essential advantage of KP system.

WHAT SHOULD BE REMEMBERED BEFORE PURCHASE OF KP SYSTEM

As we are already sure that KP system is exactly what we need and we decide to buy it, it is to remember that we should collect some basic information that will ensure us proper selection of features for our chimney duct. The most relevant is precise dimof the chimney duct cross-section. Mostly it is square-shaped, but sometimes, especially in older buildings, it is rectangular. The diameter should be fitted according to the power of condensate boiler. It is important for a proper chimney draught- the most relevant element that influences on the right chimney and heating appliance work. Condensing boilers require particular attention in matching proper diameter. It is important that the diameter should not be fitted according to the cross-section of chimney shaft (as it happens in other chimney systems). In case of condensate boilers, matched diameter should enable proper functioning of appliance, and should not cover the surface of chimney shaft (in case of condensing boilers the situation is opposite- the surface of the liner is considerable smaller than chimney shaft surface.) When we already know the diameter, we have to know how high should be our chimney. The high of chimney determines the amount of such parts as pipes and centring clamps, that ensure vertical position and eliminate danger of deflection. In exhaust system for condensing boilers there is a possibility of applying This should also be taken into consideration. Moreover we have to know the diameter of boiler outlet pipe and the distance between heating appliance and chimney shaft. That information is required for selection of proper connection parts. If the diameter of a boiler outlet pipe differs from the diameter of chimney duct it is to remember that the reduction is necessary. In such a way we could be sure that the purchased system will perfectly fit our chimney shaft as well as applied boiler.

CORRECT INSTALLATION GUARANTEES NON-FAILURE OPERATION OF STACK SYSTEM. PRACTCAL INSTRUCTIONS FOR LONG-LASTING CHIMNEY OPERATION

Installation of chimney system constitutes one of the main factor that influences on proper functioning. According to that it should be carried out by specialized team. Before installation the chimney shaft should be precisely cleansed of combustion products and other redundant elements like: destroyed bricks etc. All opening in wall should be also prepared. After above mentioned activities you can proceed with the right installation of chimney duct. It is relevant to connect each element properly as any negligence is unacceptable in order to user's safety, that is provided by tightness of installation. Chimney duct should be installed vertically. For this purpose fixing clamps every 3 m are recommended to be used. After installation, the last thing to do, is to check the functionality of chimney system and to enjoy its proper and long-lasting work.

WHAT IS GUARANTED BY KP SYSTEM

- high quality

- possible selection of appropriate diameter according to the diameter of chimney shaft.

- safety and usage comfort

- chimney ducts take smaller surface

- economy regarding to max. use of boiler power

- easy installation

KP SYSTEMNOVELTIES

In an offer of pipes and fitting for closed chamber heating appliances and condensing boilers, Kominus company meets high expectations of customers and introduces coaxial pipes of MAXIDUALFLEX type with kit of upper, intermediate and bottom fittings. MAXIDUALFLEX® – is a new flex- new flexible pipes. Up to that moment t
the installation of flexible pipes for condensing boiler was impossible. Our experts created such a flex and MAXIDUALFLEX® came into existence. In accordance to basic construction KP MAXIDUALFLEX® consists of external duct- space between the duct's walls, which sucks in the air also from the internal duct, that carries away flue gases. Using gaskets within the internal duct has to protect in 100% the tightness of a connection. Now the chimney shaft with irregulars within cross-section or eventual necessity of changes in chimney duct direction is not problem anymore for condensing boiler users.

KPD INSULATED SYSTEM 30 MM INSULATION- KPD KOMINUS SYSTEM

Another novelty is KP system with insulation- KOMINUS KPD SYSTEM. Typical construction of KP system has been expanded with an insulation of 30 mm stone wool as well as 0.5 mm external stainless steel jacket . Such type of construction is an excellent solution for people who has condensate boiler and are willing to put their chimney duct outside the building. Insulation protects from over-cooling of chimney walls, what in effect can caused to chimney draught disturbance.

TYPICAL CHIMNEY CONSTRUCTION

All chimney systems we manufacture meet high quality requirements, which are confirmed by the obtained certificates. The issuer of the certificates is MPA NRW - MATERIALPRÜFUNGSAMT NORDHEIN-WESTFALEN, a recognized independent institute for testing product compliance with standards. Due to the laboratory capabilities, experience and staff of specialists, it is the most recognized institution controlling compliance with standards.
