Technical description Boiler transport The XL-W is a fully equipped compact The boiler can be moved using a fork-lift Lifting and carrying precautions: heating system, which has been pre-set or pallet truck.Unpacking instructions are - Wear protective clothing and gloves and tested at the factory.

When the boiler is positioned with less free space, maintenance activities will be more difficult. If you have opted to build the hydraulic part yourself, then ATAG recommends using “Connection set XL-W as single boiler” for each boiler.
When installing the a single XL-W boiler or cascade XL-W boilers, the use of a low loss header adjusted to the set de- mand is strongly suggested. ATAG Heating Solutions offer optional matched low-velocity mixing headers suitable for heat outputs up-to 1600kW.

- Collective flue gas outlet over-pressure specific regulations. ATAG can supply a collective flue gas outlet system for the ATAG XL-W. Refer to the following chapters with regard to the various possibilities and maximum pipe lengths than can be used.
Flue gas system Requirements and regulations Materials Flue gas data Notes The tables below give guidance on the maximum lengths of air and flue gas tubes that may be connected. If a room sea- led installation is being made utilising separate air and flue gas tubes, the lengths of both tubes must be added together and not exceed the relevant value given in the tables.
