Fuel storage

1.4.1 Automated pellet supply

The pellets can be stored in bulk in a storage room, sheet steel tank, fabric tank or a buried tank. See the sep-
arate "Pellet storage room" planning documents for planning information about this pellet storage.
The requirements for pellet storage are defined in ÖNORM M7137 for Austria or the Firing Ordinance FeuV for
Germany.
The pellets must be stored in a dry place in order to achieve trouble-free operation with optimum combustion
and at maximum efficiency.
The pellets must be transported carefully into and out of the storage room so as to maintain good
pellet quality.
The maximum transport length or height for a pellet feed system is 25 m horizontally with a 6 m vertical dif-
ference between the highest and lowest levels of the hose. These maximum values require a stable electricity
supply (min. 220 VAC under load).

1.4.2 Manual pellet supply

Pellets in bags must be stored in a dry place.
Please observe the local regulations on storing fuel.

1.5 Application options

FireWIN is designed for installation in the living area and is configured as a fully featured central heating system.
This means no second heat generator is required. If desired, however, FireWIN can be combined with alterna-
tive heat generators (e.g. solar or solid fuel boiler). Refer to the hydraulic systems for details about this.
The necessary hydraulic components for a heating circuit as well as hot water preparation are integrated in
FireWIN (see hydraulic equipment). This means there is no longer any need for a boiler room or equipment
room and that FireWIN is ideally suited for use as a central heating system in houses without a basement or
when central heating is being installed in a building for the first time as part of a renovation project.
1.6

Flue

A properly dimensioned flue is required for optimal functioning of the combustion system. Measurement of the
dimensions must follow EN 13384-1. See the Technical data section for values required for this calculation.
Please note that in the lower performance range, flue gases may be below 90 °C. Therefore, thermally-insulat-
ed flues meeting thermal transmittance coefficient Group I requirements according to DIN 18160 T1 or other
appropriate, officially approved moisture-resistant exhaust systems may be connected to the hearths.
Frequently, these requirements on the flue are not satisfied during the renovation of existing systems. We there-
fore suggest an evaluation by the local building inspector before installing the boiler system. In this way appro-
priate modifications can be made to the flue before system installation. (See the technical data for flue calcu-
lation values.)
Energy-saving intake regulators or explosion flaps are not allowed to be installed in the living area.
Comply with the statutory regulations and directives.
