6 Requirements at the installation location
6.1 Requirements at the room of installation
Your pellet stove must not be set up in:
• spaces in which the required combustion air supply is not guaranteed.
• spaces which are generally accessible, in particular emergency exits (staircases in residential build-
ing with no more than 2 apartments are not included in general accessible spaces).
• spaces in which easily flammable or potentially explosive substances or mixtures are processed,
stored or manufactured.
• spaces, apartments or units from which air is extracted with the aid of ventilators, such as ventila-
tion- or hot-air heating installations, extractor hoods or exhaust air tumble dryers. Unless the safe
function of the stove is ensured.
This is ensured if:
– the systems only circulate air within a space.
– the systems have safety features which autonomously and reliably prevent negative pressure in
the installation space.
– simultaneous operation of the fireplace and the air-extracting system is prevented by safety
features.
– the flue gas routing is monitored by a particular piece of safety equipment.
Floor load-bearing capacity
Before installing, verify whether the load-bearing capacity of the substructure can withstand the weight
of your stove.
6.2 Chimney requirements
To protect your own safety, national and local regulations exist governing the connection of flue pipes
to the chimney. Rocket is set up at the factory for connecting to 130 mm flue diameter / top. With
minor modifications on site it can also be connected at the rear. When connecting with other pipe dia-
meters, you should obtain the prior approval of your chimney sweep. Your specialist stove dealer will
be familiar with the guidelines. For your own safety the flue connection should be carried out by a spe-
cialist.
6.3 Combustion air / Outside air supply
This stove requires sufficient combustion air to operate smoothly. With dense building envelopes, the
room air is insufficient. For this reason, the combustion air required must be supplied from outside.
Your stove is prepared for this situation (balanced flue operation). The external air supply pipe must be
connected tightly to the stove (e.g. with a pipe clamp or airtight adhesive tape). Your dealer will advise
you on the correct connection.

Operating manual Rocket EN 6 | Requirements at the installation location
15
Fig.6: Connection from rear
The connection for the external air supply features an outer
diameter of 125 mm. It is located at the rear of the stove,
below the combustion chamber Fig. 6: Connection from
rear [}on page 15]
Fig.7: External air supply connection, rear /
perforated sheet metal cover
The connection for the combustion air supply is visible from
the outside when the lower side panel is removed (see fig.
6).
The connection must be made with a flexible hose. If the
connection is made from the rear, the perforated plate at
the back of the stove must be broken out (see Fig. 7).
6.4 Multiple occupancy
The ROCKET pellet stove is suitable for connection to a chimney occupied by other cookers and
ranges burning solid fuels (multiple occupancy). A minimum delivery pressure (see Data for the chim-
ney/flue dimensioning [}on page 13]) is required to operate ROCKET.
6.5 Balanced Flue Operation
Rocket can also be operated without the need for room air.
If the combustion air is supplied directly to the fireplace from outdoors by means of a sealed pipe with
a shut-off device, the stove may also be operated in utilization units with mechanical ventilation or air
extraction. If, however, the stove is used in this way, multiple occupancy of a chimney is not permitted.

7 | Fuel/fuel quantity EN Operating manual Rocket
16
7 Fuel/fuel quantity
7.1 Fuel
Fig.8: Pellet
Fig.9: ENplus A1
Pellets
Poor pellet quality will cause significant residues in the pel-
let oven when burnt. We therefore urge the use of pellets
that have no artificial binding agents. That way only a small
unburnt residue is left.
ENplus-A1 certified pellets meet this requirement.
When storing the pellets it is vital to ensure that they are
stored in a cool dry place free of contamination. Damp and
dirty pellets result in poor combustion.
Fuel
Only burn the recommended fuel.
Explosive substances
It is strictly forbidden to burn or introduce highly flammable or explosive substances (empty aerosols
and the like) into the firebox or to store them in the immediate vicinity of your stove. Risk of explosion!
7.2 Fuel quantity
Maximum fuel quantity
The hopper of your pellet stove has room for a maximum of 7 kg of pellets. These last for approxim-
ately 14 hours of heating operation and approximately 7 hours at nominal load.

Operating manual Rocket EN 8 | Information on the operation of your Rocket
17
8 Information on the operation of your Rocket
8.1 Clean combustion
Good fuel quality, the right chimney/flue draft and the correct setup and connection of your ROCKET
guarantee clean combustion.
8.2 Always start in max position
The start of your Rocket is automatically controlled by BIMETALLS. In order to guarantee the automatic
control of the start, the output regulator must be set to the MAX POSITION.
8.3 Combustion
After approximately 40 minutes, the automated start is completed. You will see this by the flame pat-
tern. At the end of the start phase the output of the Rocket can be set as desired with the output regu-
lator. Each change of the output regulator position results in a change in the output only after a notice-
able delay in the combustion chamber.
NOTICE
Throttling the heat output prematurely using the output regulator will cause the windows and the
combustion chamber to blacken.
8.4 Burnout
When no more flames are visible in the firebox or when there are no more pellets in the hopper, the
stove is in burnout mode. The bed of embers on the grate keeps the stove warm for another 2 hours.
No more pellets may be added during Burnout! (Danger of deflagration!)
The Rocket may only be operated with the firebox door shut, the hopper closed, the ash pan locked
and the grate closed.
Only open the firebox door during operation in exceptional situations!
NOTICE
Remember: It is not possible to terminate the burning process prematurely.

9 | Commissioning EN Operating manual Rocket
18
9 Commissioning
9.1 Initial Commissioning
During initial commissioning below nominal heat output (5 kW) there may be an odour nuisance. The
reason for this is the stove varnish. This only hardens during operation. The varnish releases vapor in
the process. Therefore, make sure that the room is well ventilated during the initial commissioning.
Furthermore, soot formation is more pronounced during the initial commissioning due to the in-
creased moisture content of the firebox lining generated during the production process.
Please note that there may be some slight expansion- or contraction noises when the stove heats up or
cools down (soft crackling, soft clicking, etc.).
This is caused by the various materials expanding and contracting under the influence of temperature
in your oven. Noise of this kind does not constitute a warranty claim.
9.2 Preparing the stove for operation
Fig.10: Set output regulator to “max” posi-
tion
1) To ensure the heating appliance operates correctly
and safely, it is important that the chimney generates
the required draft. When restarting the stove (e.g.
after the summer season) and in adverse weather con-
ditions (e.g. strong wind), problems may arise with the
draft.
To avoid delivery pressure problems in the chimney
flue/chimney, at the start the output regulator must al-
ways be set to the “max” position.

Fig.11: Shaking the riddling grate
2) If the stove was already in operation and there is
residue in the riddling grate, you can press and pull
the lever (1) to shake the riddling grate up to 3 times.

Operating manual Rocket EN 9 | Commissioning
19
Fig.12: Pellet hopper
Filling the pellet hopper
1) Open the hopper hatch of the stove.
2) Use a suitable container to fill the desired quantity of
pellets.
NOTICE
The pellet stove cannot be halted during the burning
phase. All the pellets loaded must be burnt. Therefore, ad-
just the quantity filled and the output level to suit the de-
sired burning time.
At nominal load, the stove consumes approximately 1 kg
pellets/hour. At partial load, the stove requires approxim-
ately 0.5 kg of pellets per hour.
