8 TWIN - GAS TWIN - GAS SYSTEM A s a stainless steel concentric balanced flue system, TWIN-GAS uses the annular gap between the inner pipe carrying the flue gases and the outer pipe to carry the intake air. A special gasket in the outer pipe makes it pressure tight and thus prevents the combustion air from mixing with the air in the room. The flue solution for decorative fires The extraction of the hot flue gases causes a vacuum in the gas fireplace, which is balanced at the collar of the flue by incoming intake air, creating a natural circulation. The intake air is extracted through the collar (wall or roof terminal), as flue gases are blown out and intake air are drawn in with the same pressure level, so that the so-called "balanced flue" cycle works properly. To prevent the air in the room from being drawn in via the push-on connection, the TWIN-GAS has a silicon sealing ring, which is glued into the box groove of the outer pipe. 8

9 PROPERTIES Seal in the outer casing In standard operation mode the outer pipe of the system can only reach a maximum temperature of 180 C, Jeremias gurantees the correct operation mode even with smoke temperatures of 600 C. The silicone seal is factory glued into the internal socket of the outer pipe and guarantees the tightness of the system even with hight smoke temperatures. Advantages: > Prevents the air intake from mixing with the air in the room > Hermetically sealed system > The glued silicon seal minimises the risk of leaks due to slippage or damage to the seal during installation > Blower door test capability Blower door test Blower door tests are becoming increasingly common in new builds and refurbishment projects in order to detect any weaknesses in a building's air-tight seal. This first involves creating a vacuum in the building and then checking to see at which points air enters the building. The glued seal enables the TWIN-GAS system to prevent the intake air from escaping and the air from the room from entering the annular gap if overpressure is generated in the living room in phase 2 of the blower door test. Annular gap Box groove Glued seal Spacers Freely movable inner pipe Special spacers are used to centre the inner pipe in the outer cladding and, at the same time, to allow the longitudinal expansion of the internal pipe at high temperatures as there is no fixed connection between the internal and external pipes. 9

11 SYSTEM CLASSIFICATIONS The declaration of performance provides information about the classification of the flue gas system. It lists product properties and specific installation requirements and thus offers evidence of the suitability of the relevant flue gas system. The classification of the TWIN-GAS system comprises of following: Model 1 TWIN-G DN (60-200) T600 N1 W V2-L50040 O50 Possible inner diameters Temperature class T600: Operation up to 600 C gas temperature Pressure class N1: Low pressure Condensate class W: Suitable for both wet or dry operation Corrosion resistance class for the flue liner material V2: Oil, Gas, solid fuel for wet or dry operation Material specification for the inner pipe L50: Material quality of the inner pipe 040: Wall thickness of the internal pipe min. 0.4 mm Soot fire resistance O: not resistant to soot fires Minimum ventilated distance from flammable building materials 50 mm 11

12 SELECTED INSTALLATION VARIANTS 1 Installation on an outer wall The TWIN-GAS connecting pipe is routed from the gas fire through the wall to the building's exterior. The riser begins with a base plate (with condensate outlet, cleaning and T-piece) and ends with a vertical terminal. 2 Installation in an existing brick chimney* The set-up is largely the same as for variant 3, however in this case the flue gases are channelled upwards by means of elements of the TWIN- GAS system in the shaft. Here too, elements of the EW-FU system can be used to support the weight on the shaft base instead of the bearing rail. * This variant is only permissible in Germany and other countries after prior consultation with the responsible authorized district chimney sweeper. 12

This ensures that the flue gases are released from the top, while the intake air is mostly drawn in from down below.

Installation with ceiling and roof* The TWIN-GAS system is directly installed vertically above the gas fire.

The flue gas is released and the intake air is drawn in by means of the roof terminal.

13 SELECTED INSTALLATION VARIANTS Installation with a horizontal wall terminal* 3 4 Exhaust gas and intake air are channelled by means of the concentric TWIN-GAS system and a horizontally installed wall terminal with eccentric internal pipe. This ensures that the flue gases are released from the top, while the intake air is mostly drawn in from down below. This minimizes the recirculation of flue gases back into the system. Installation with ceiling and roof* The TWIN-GAS system is directly installed vertically above the gas fire. An L-90 lightweight shaft is used to clad the flue gas system on the upper floor. The flue gas is released and the intake air is drawn in by means of the roof terminal. * This variant is only permissible in Germany and other countries after prior consultation with the responsible authorized district chimney sweeper. * This variant is only permissible in Germany and other countries after prior consultation with the responsible authorized district chimney sweeper. 13

The termination is through a shaft cover plate with transition from EW - FU or EW - LINE FLEX to a concentric pipe in order to connect with the TWIN - GAS roof terminal.

15 SELECTED INSTALLATION VARIANTS 5 Installation in an existing brick chimney A TWIN-GAS connecting pipe leads from the gas fire to the shaft. Starting from a base plate, the flue gas is extracted using elements of the EW-FU and/or EW-LINE FLEX systems, while the intake air is supplied from the shaft. The termination is through a shaft cover plate with transition from EW - FU or EW - LINE FLEX to a concentric pipe in order to connect with the TWIN - GAS roof terminal. 6 Installation in an existing brick chimney* The set-up is largely the same as for variant 1, however, instead of the base plate, a 90 bend with supporting foot is used which is secured by means of a bearing rail in the flue. Alternatively, the weight can also be supported by means of elements of the EW-FU system. * This variant is only permissible in Germany and other countries after prior consultation with the responsible authorized district chimney sweeper. 15

16 TWIN - GAS INSTALLATION INSTRUCTIONS Installation direction of sleeve/groove All components are to be fitted in a way that the sleeve of the internal pipe always points in the direction of the flow of the flue gas. This prevents condensate from escaping into the annular gap. On the other hand, the sleeve of the outer pipe faces in the opposite direction to the flow to prevent rainwater from penetrating the annular gap from outside.
