Technical description Boiler transport The R0XXX 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 RENDAMAX recommends using “Connection set R0XXX as single boiler” for each boiler.
When installing the a single R0XXX boiler or cascade R0XXX boilers, the use of a low loss header adjusted to the set demand is strongly suggested. Rendamax Heating Solutions offer optional matched low-velocity mixing headers suitable for heat outputs up-to 1600kW.

- Collective flue gas outlet over-pressure specific regulations. RENDAMAX can supply a collective flue gas outlet system for the RENDAMAX R0XXX. Refer to the following chapters with regard to the various possibilities and maximum pipe lengths than can be used.
Flue gas system Maximum flue gas lengths single boiler 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.
