5. HOS Applications
The HOS electronic combustion control can be used for the following types of fireplaces:
· Residential cookers fired by solid fuel according to DIN EN 12815
· Residential cookers (with a water heat exchanger) fired by solid fuel according to DIN EN 12815
· Chimney inserts for tiled stoves for solid fuels according to DIN EN 13229
· Heating or chimney inserts for solid fuels with a water heat exchanger according to DIN EN 13229
· Standalone woodburning stoves or room heaters for solid fuels according to DIN EN 13240,
· Standalone woodburning stoves or room heaters for solid fuels with a water heat exchanger according to DIN EN 13240
· Tested, room air-independent fireplaces in accordance with the above standards if the requirements of the approval for installation
cannot be met
· Heating inserts for tiled stoves for solid fuels with metallic heating gas flues or heating boxes according to DIN EN 13229
· Handcrafted storage fireplaces with heating inserts or chimney inserts for solid fuels with ceramic heating gas flues according to
DIN EN 13229
· Slow heat release appliances fired by solid fuel according to DIN EN 15250
· Masonry heaters according to TROL
· Fireplaces according to 15a B-VG
6. Position of pressure and temperature sensors
6.1 General information
· For proper function of the electronic combustion control HOS, the position of the pressure and temperature sensors must be
chosen according to the type of the fireplace installed.
· The flue gas temperature sensor must be installed in the combustion chamber or in the smoke outlet to ensure proper temperature
measurement.
· When installing the sensors, the instructions from both chapters 7.2 and 7.9 must be followed.
Flue gas temperature sensor’s cable as well as the silicone hose must be installed in such a way
as the safe distance from hot surfaces (e.g. exhaustion pipes, fireplace body, etc.) is ensured.
Surrounding temperature must not exceed 180 °C.
The installed silicone hose and flue gas temperate sensor must always be accessible through a
revision opening, in cases of maintenance or service. (Fig. 4)
Install the room pressure sensor in the room of installation or in the place air-connected to the
installation room. (Fig. 4)
The electronic combustion control HOS with the underpressure watcher (MODULE U) is only approved
for single assignment. Usage in multiple occupancy is not allowed.
