protocol“ on page 52). When first putting your appliance into service, only
start a moderate fire. This enables you to avoid cracks in the combustion
chamber covering (which may still contain residual humidity before the first
firing). Slowly increase the heating power to about 30% above nominal heat
output by setting the fire 3 to 5 times to give the corrosion coating applied
to the surfaces time to 'burn in' properly The paint can be slightly soft
during this process, please do not place any objects on the stove and do
not touch your device. During this burning-in process, an unpleasant odor
(sometimes accompanied by the build-up of smoke) may appear. Ensure the
provision of good room ventilation for this burn-in process. Open all doors
and windows to the outside of the building.
Initial commissioning of Senso M H

O
The initial commissioning must only be executed after all necessary com-
ponents are connected and all necessary safety devices are integrated
and functional, the water heat exchanger is filled and the system has been
ventilated. Operation without water, when only partially filled or when safety
devices are not functioning is not permitted! During initial commissioning
of the water heat exchanger, it may be necessary to vent this several times.
Moreover, the owner must be instructed in detail concerning the operation,
function and maintenance of the overall system, including all supplemental
components. In addition, the measures for maintaining safe operation of the
system must be communicated to the owner. The executed instruction must
be documented in the commissioning protocol (see „10. Commissioning
protocol“ on page 52.). The installation and operating instructions must
always be kept in the vicinity of the Senso M H

Contaminated condensate exiting the combustion chamber liner may con-
taminate/damage the base unit. Here an absorbent pad should be placed
under the unit for the first burn-ups until condensate no longer emerges.
Before commissioning, check to ensure there are no objects in the combus-
tion chamber/in the ash drawer. These must be removed.
During heating and cooling, metallic grinding noises may be heard as the
components of your stove expand or contract. These are completely normal
and arise as a result of material expansion caused by the high temperatures.
4.1.1 COMBUSTION AIR REGULATION
Combustion air is regulated across an infinitely variable range using the
actuating lever located under the door. Adjustment takes place with the fire
door closed!
Air supply opened (A): For heating-up or for adding more firewood, move
the actuating lever fully to the right. The combustion chamber will now be
supplied with the maximum amount of air for primary and for secondary
combustion purposes.
Throttled combustion (B): leave the setting lever in a near-central position.
The primary combustion air supply is now closed, ensuring that the fire is
not supplied with too much air. Secondary air is diverted across the ceramic
viewing glass to prevent it from sooting up. This is the default position while
a fire is burning. The precise position
depends on local conditions and can be
adjusted by the operator to reflect the
combustion characteristics of the stove.
Air flow closed (C): actuating lever at
far left. The combustion chamber of the
stove receives no combustion air in this
setting. However, do not shut down the
air supply altogether until the fuel has
burned away completely. If the fireplace
is not in operation, you should always
close the air supply.
