NOTE: DISTANCE TO NON-FLAMMABLE
MATERIALS
To avoid obstructing air circulation around
the stove we recommend a clearance of at
least 5 cm in front of and next to the stove.
NOTE: T E M P E R AT U R E - S E N S I T I V E
MATERIALS
Temperature-sensitive materials such as
glass or plastic may require greater
clearances than the safety distances
specified.
4. Connection of Multiple Devices in
Direct Vent Operation
When the PATNA is operated as a direct vent
model, more than one device can be connected to
the chimney under the following conditions:
CAUTION!
Multiple appliances per chimney are
permitted in line with the applicable national
and regional regulations.
All connected fireplace stoves must be
in the same building unit or in the same
effective area of the ventilation system.
The inlets for the combustion air ducts are
located in areas of equal pressure (same
pressure ratios), wind-induced pressure
fluctuations have to be avoided.

NOTE!
In England (UK), according to the
applicable
building
regulations
Building Regulations 2010: Combustion
appliances and fuel storage systems, point
1.25), each solid-fuel appliance is required
to have its own chimney.
5. Fuel Load Sizes and Thermal Output
The thermal output depends on the amount of
fuel you put in the stove. When adding more fuel,
please do not exceed the maximum fuel load size of
2,5 kg. The fuel can be filled to the maximum height
of 20 cm in the combustion chamber. Exceeding
the maximum fuel load size leads to a danger of
overheating, which can result in damage to the
stove and the risk of a stove fire.
NOTE!
To attain a thermal output of approx.
7,5 kW, burn wood logs that weigh a total
of 1,65 kg and are no longer than 25 cm in
length for about 44 min.
The PATNA is intended for intermittent operation,
please only apply one fuel layer at a time.
NOTE!
The stove can be fitted with heat retaining
stones. The heat retaining stones store the
heat and release it into the environment
over several hours:
► Installation: See installation and
maintenance instructions.
(The
5.1
Wood Briquettes
You can also fuel your PATNA with wood briquettes
as specified in DIN EN ISO 17225 or of equal
quality. Please note that wood briquettes swell and
expand during combustion. As compared to the
amount of fuel when using logs, reduce the amount
by approx. 10-20% based on the calorific value of
the wood briquettes. The control element settings
and procedure are the same as when burning logs.
