The heater is mainly made up of following items:
1. Combustion burn pot
2. Exhaust fan
3. Room circulation fan and auger motor.
The following is a list of main components and their
functions:
IGNITER
The HEATER comes equipped with an automatic electric
igniter for lighting the fuel when the heater is in lighting
mode only.
The igniter remains energized for the rst eight minutes of
the lighting sequence.
VACCUM SWITCH
The HEATER has a safety vacuum switch located behind
the left door, fastened to the base.
If a low pressure is created in the rebox by a leak,
opening the front door, a blocked ue, or unsealed ash
drawer, the vacuum switch will sense it and cause the
heater to go into a shutdown mode.
AUGER AND AUGER MOTOR
The 2 RPM auger motor turns the auger lifting pellets up the auger tube.
The pellets ed down a tube and into the repot. The auger is controlled by the control board.
OVER TEMPERATURE THERMOSTAT
This safety switch is installed on the bottom of hopper and will shut o󰀨 the heater if it senses
excessive temperatures (70 degrees).
CONVECTION BLOWER THERMOSTAT
This switch is installed on the vent pipe and turns the convection blower on when the heater is
above 40 degrees.

4. PELLET STOVE INSTALLATION
All NATIONAL AND LOCAL REGULATIONS AND EUROPEAN STANDARDS SHALL BE
COMPLIED WITH WHEN INSTALLING THE APPLIANCE
Before installing a stove in a room, select the right stove to be able to heat the room.
Please check the STOVES’ Heating area in the Chapter of STOVE FEATURES.
GENERAL INFORMATION
The stove must be connected to a chimney that is approved for solid fuels. The chimney must have a
diameter of at least 80 mm.
The ue system is based on negative pressure in the combustion chamber and a slight overpressure
on the ue gas outlet. It is therefore important that the ue gas connection is tted correctly and is
airtight.
In addition you must ensure that the ue tube does not project into the free cross section of the
chimney.
Only use heat resistant sealing materials, as well as the relevant sealing bands, heat
resistant silicon and mineral wool.
Only authorized technical personnel must carry out assembly work.
NOTE: Please follow the regionally valid building regulations. Contact your master
chimney sweep for information regarding this.
ASSEMBLE THE STOVE BEFORE INSTALLATION

8
Version: 9a
13.11.2018
EN
Ensure that outlet routes to the chimney are not too long.
Avoid too many changes of direction for the ue gas ow to the chimney (e.g. too many corners and
bends).
If you cannot connect directly to the chimney, use a connection piece with cleaning opening if
possible.
For optimum e󰀩ciency please use the type of connector we recommend.
Horizontal
(This is not recommended,
when the electronic power
is o󰀨, the smoke might come
out if the stove is on
Horizontal and up through
the eave.
MAKING THE CHIMNEY CONNECTION

9
Version: 9a
13.11.2018
EN
Method
1. Measure and draw the chimney connection (taking any oor plate thickness into consideration).
2. Chisel out (drill) the hole in the wall
3. Brick in the wall lining
4. Connect stove with the ue tube to the chimney.
FLOOR PROTECTION
For ammable oor surfaces (wood, carpet, etc.) a glass, steel plate or ceramic underlay is required.
ELECTRICAL CONNECTION
The stove is supplied with an approx. 2 m long connecting cable with a plug. The cable must be
connected to a 230 V, 50 Hz electrical supply.
The average electric power consumption is approx. 100 watts during heating.
During the automatic ignition process (duration 10 minutes) approx. 350 watts.
The connection cable must be laid so that any contact with hot or sharp-edged external surfaces on
the stove is avoided.
SAFETY DISTANCES (measured from the outside of the stove)
From non-combustible objects
A > 400 mm, B > 100 mm, C > 100 mm
From combustible objects and to load-bearing walls in reinforced concrete
A > 800 mm, B > 200 mm, C > 200 mm

COMBUSTION AIR
Each combustion procedure requires oxygen or air. As a rule this combustion air is removed from the
living area for individual stoves. The air taken from the living area must be reintroduced.
In modern houses, very tight tting windows and doors can cause that not enough air ows back.
This situation becomes problematic due to additional ventilation in the house
(e.g. in the kitchen or WC).
The suctioning in of combustion air is performed via the ue gas blower.
The resulting combustion air and suctioning noises are normal operational noises that may occur at
varying volumes depending on the chimney draught, output level or a dirty combustion trough
– NOT A CAUSE FOR COMPLAINT!
Feed of external combustion air
● Steel, HT or exible aluminum pipes must be used.
● Minimum diameter 5 cm/2 inches.
● For longer connection runs the diameter must be increased to approx. 10 cm after approx. 1 m.
● The pipe should not be longer than approx. 4m in total to guarantee adequate air feed and not
have too many bends.
● Should the line lead into the open air, it must end with a vertical 90° downward elbow or with
a wind guard. Should one or more of these conditions NOT be applicable then usually poor
combustion will occur in the stove, as well as air under pressure in the apartment.
We recommend that a ventilating grille be tted in a window near the stove for permanent ventilation.
Further it is possible to extract the combustion air directly from outside or from another room that is
well ventilated (e.g. the cellar).
Please observe:
Your pellet stove works independently of the room air. Negative pressures in the set-up room are not
permissible. Therefore the use of a safety device (e.g. di󰀨erential pressure controller) in combination
with room air facilities (e.g. ventilation system, exhaust extraction etc.) is stipulated.
