Fireplaces equipped with a water boiler must be pressure-tested after hydraulic connection to the heating system. Masonry work may follow only after this pressure test. Ulrich Brunner GmbH does not cover any costs incurred by necessary dismantling of masonry for rework at water boiler installation or replacement of the boiler.

If additional parts are installed on the fireplace which are not approved for this appliance by Ulrich Brunner GmbH (for example, an external control unit), it is a customized product that meets cus- tomer requirements. The resulting fireplace insert is not type-tested; the declaration of performance of this fireplace insert will be no longer valid.

Page 17: Requirements For Location
- If the construction type or dimensioning of the systems are excluding the possibility of dangerous negative pressure. Please consult the location of your fireplace, chimney connection and combustion air supply with your local chimney sweep. © 2023 Brunner GmbH (1.19)
Page 18: Combustion Air
(calculation of flow and thermal balance and ap- proval from chimney sweep are necessary). However, it is not possible for fireplaces designed for open door use. Remember to use a separate chimney connection in this case. (1.19) © 2023 Brunner GmbH...
Page 19: Mounting Instructions For Eas / Eos Variants
Installation of electronic components must be prepared and performed carefully. Please pay attention to the following points: • The flush-mounting box must be fitted in level and clean, to ensure easy, tension-free installation of elec- tronics. © 2023 Brunner GmbH (1.19)
Page 20 All electronic components must be accessible after installation for revision and replacement. When selecting place of installation, keep in mind the max. permitted temperature for the component. Components cannot be installed in closed spaces; proper ventilation must ensure sufficient heat discharge. (1.19) © 2023 Brunner GmbH...

Page 24: Building Protection
Required insulation measures depend on the type and design of the surface. The load bearing capacity of the mounting surface must be checked; appropriate means for load distribution must be taken if necessary. (1.19) © 2023 Brunner GmbH...
Page 25 Active air cooling is a permanently open, non-closing shaft, gap or empty space, where part of the heat pro- jected by the fireplace is dissipated by convection to protect the building or flammable components in adja- cent walls or mounting surface. © 2023 Brunner GmbH (1.19)
Page 26: Connections And Assembly
Heating gas pipe (21) between heating device and downstream heat radiator or storage mass, as well as the smoke pipe connecting piece (39) connected to chimney must be made of heat-resistant steel with CE mark. The connecting pipe must be connected directly to the chimney. When the connecting piece is leading (1.19) © 2023 Brunner GmbH...

Page 28: Approved Insulation Materials
The dimensions and design of active trim must be adapted to the heating power of the heating device. APPROVED INSULATION MATERIALS Thermal insulation materials used must fulfil the following requirements according to AGI-Q 132 standard: (1.19) © 2023 Brunner GmbH...
