    In case of a discharge the gasses will go outside. If fitting the regulator outside the regulator should be protected against influences of the weather. The (de-) aeration must be positioned downwards (see figure 9.5.3.a). ATAG advices to install measure points on all gas line parts to have the possibility to check for pressure loss. example propane installation figure 9.4.3.a Pre-pressure must be adjusted to 37 mbar by means of the house pressure regulator. The maximum permitted closing pressure may be 5 mbar higher than the maximum pre-pressure.

    - Air supply pipe; - Roof or wall terminal. The flue gas exhaust system and air supply system must comply with: The flue gas outlet and air supply installation must comply with the current regulation requirements in accordance with BS:5440 Part 1 and 2. The ATAG iR boiler as described in this manual is NOT suitable for a combined flue system. The appliance concentric connection diameter is 60/100 mm, to which the flue gas outlet and air supply system can be fitted, with or without elbow pieces. The maximum permissible pipe length is set out in Table 9.6.2.a. For further information about the available components of the flue gas and air supply system we recommend you consult the Flue system literature. Combinations with other brands or systems are, without written permission from ATAG Heating, not permitted.

  • Page 24 In certain weather conditions the terminal will emit a plume of steam. If possible avoid positioning the terminal where this may cause a nuisance, i.e. positions A, D, G, H, J or M. 7. The flue terminal must be exposed to the external air and the position must allow the free passage of air across it at all times. 8. A terminal must not be sited below 2m where people have access to, such as public footpaths, access routes, patios etc. However, If the terminal is fitted less than 2m above a surface where there is no public access, the terminal must be protected by a terminal guard.

  • Page 27 When mounting the flue gas system, pay attention to the flow direction (See figure 9.6.2.b). It is not permitted to mount a system upside down and will lead to complaints. Use a soap solvent or special grease (supplied in the accessory bag with the boiler) to simplify the fitting. The ATAG flue system used is a push fit flue system, which does not require screws to be fitted at each flue joint. The flue system must be adequately supported at regular intervals between brackets of no more than 1.0 metres for horizontal sections and no more than Flow direction Figure 9.6.2.b 2.0 metres for vertical sections.
