Page 16: Gas Connection In General
ATAG supplies boilers suitable for natural gas only and boilers for LPG only. Verify the identification plate on the boiler if the boiler is suitable for the gas kind on site. The boilers cannot be converted to another kind of gas. - Page 17 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 30 mbar by means of the house pressure regulator. The maximum permitted closing pressure may be 5 mbar higher than the maximum pre-pressure.

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. IG UP 10 and BS 715. 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. -

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 25 BS 5440: Part 1 recommends that care is taken when siting terminals in relation to boundaries. Notes: See also Notes on previous page. 2. Plume kits running horizontally must have a 10° fall back to the boiler for proper disposal of condensate. 3. For details on specific lengths see relevant chapter Dimensioning of the flue gas and air intake duct. A terminal must not be sited under a car port roof.

Figure 9.6.2.a Installation & Servicing instructions ATAG iR-Range... - Page 27 6. If the inside sealing collar (white) is being used to make good the inside wall, then it will need to be fitted before assembling the flue. 7. Pull the flue assembly towards the bend, locating the inner duct into the seal joint on the bend and secure the flue assembly to the bend by pushing fully home. 8. Make good the outside wall by fitting the outside sealing collar (grey) onto the location provided immediately behind the flue terminal grille. Make good the inside wall using the inside sealing collar (white) if required. When mounting the flue gas system, pay attention to the flow direction (See Flue 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.
