stove.
3. Installation
3.1. General rules
Correct mounting and connection of exhaust gas system is extremely important for
safety use of pellet stove.
Any mistakes done during the installation are not covered by the MANUFACTURER.
It is obligatory the installation, the first start and the maintenance of the pellet
stove to be performed by an authorized installer/service BURNiT!
Recommendations BEFORE installing the pellet stove:
•Check the minimum volume of the room where the pellet stove is to be installed
(should be no less than 40 m3);
•Make sure there are holes for fresh air;
•Follow all the norms/standards –technical, safety and constructional;
•The proper functionality of the exhaust gases system (chimney reliability);
•It is not permitted the installation of the pellet stove to be performed in bedrooms,
bathrooms as well as rooms which already had another heating unit installed without
enough access of fresh air (another stove, gas heater etc.)
•There should not be any flammable substances in the room where the installation
will be done.
•The space around the pellet stove should be built with stones, cement or any other
fireproof material.

Installer / Service Manual BURNiT PM Comfort
Plus
8 –ЕN
The minimum distance from flammable materials must be 200 mm. In case the floor
is made of flammable material (wood / parquet floor) it must be insulated with non-
flammable one.
The steel pipes for exhaust gases must be mounted at distance minimum 1.5 m. from
any flammable materials. We recommend the pellet stove to be installed as closer as
possible to the exhaust system (chimney). The pipe system for the exhaust gases
must be with maximum 3+1 T knees and maximum 3 m. from the horizontal flow
with minimum deviation 3-5%. After the place for installation is defined unpack the
unit and check the closing of the front door.
3.2.Connecting of outer tube for fresh air flow
For proper functioning and distribution of the temperature the pellet stove must
receive enough fresh air flow and to be well positioned (a special opening for fresh
air could be done for example). The opening for the fresh air must be minimum 100
cm2 and there should not be any obstacles on its way. Fresh air could be taken also
from other room which has its own constant ventilation and no other pellet stove or
similar heating system, which needs also fresh air flow. This room cannot be
bedroom, bathroom or any other room that are fire hazard for instance garages,
basements, stores etc. If the pellet stove in the room uses gas from an open system
or another source of harmful gases the air flow must come directly outside the room
from the environment.
Example: Connection of tube for fresh air flow directly from the outside
For proper functioning of the pellet stove it is recommended to make a direct
connection from outside the room with steel pipe 80 мм. with silicon gasket. The
part of the tube that goes outside the room must be situated downwards 90° - in this
way a protection against wind, water, etc. is achieved.
Keep the following distances:
1,5 m floor,
1,5 m horizontal,
0,3 m from doors, windows
2,0 m exhaust gases system.
The manufacturer bares no responsibility for damages caused by not keeping the
instructions.

3.4.Exhaust gas system requirements:
Exhaust gas system meet the following requirements:
• made of suitable materials.
• hermetically sealed - silicone gaskets on chimney tubes
• to be suitable for wok mode under high pressure and temperature 200°C -250°C
(recommended thickness of the pipes no less than 1mm).
•In case you want to connect the pellet stove to the already existing exhaust gas
system (chimney), its condition must be validated by an authorized installer.
•It is recommended the exhaust gas system (chimney) to be cleaned periodically.
3.5. Type of tubes for exhaust gas system (chimney)
The tubes must be solid, smooth inside, mad of steel and must be accompanied by
silicone gaskets.
The diameter of tubes long up to 3 m. must be 80 mm.
The diameter of tubes long more than 3 m. must be minimum 100 mm. as it is
necessary to obtain the required draught of the chimney (see 3.3).
The length is calculated as the requirements in 3.1 are kept.
ATTENTION! Do not connect the exhaust gas system to a chimney in which already
is connected another stove, boiler or ventilation system!

3.7. Roof installation of exhaust gas pipe
The upper part of the pipe (chimney) is dеsigned for the proper outlet of the exhaust
gases in the atmosphere. The tube must be protected from rain, snow and all
objects, and to ensure discharging of exhaust gases in the atmosphere under windy
conditions.
Requirements for the upper part of the tube:
•The inner part must not be less than the one on the pellet stove;
•The outer part of the pipe to be insulated;
•The authorized installer must protect the system from rain, snow and winter.
•Easy dismounting for cleaning;
•The type of the tube must be such that fits in the aesthetic appearance of the
building;
•Not to be close to obstacles and other chimneys.
The distance between the tube and other obstacles (walls, trees and others) must
not to be less than 10 m. If the distance is less than 10m the height of the tubes must
be 1m above the obstacles (walls, trees, etc.).
If there are other chimneys –the exhaust gases pipe must be at distance no less than
2m from it.
We recommend the exhaust gases pipe to be at least 1m above the roof.
Problems with exhaust gases
Among all the atmosphere influences on the system the wind matters most.
3.8. Connection to the power supply
Once the pellet stove is installed in the room it must be connected to the power
supply. The power cable is situated at the back part of the pellet stove. Check the
condition of the cable. If any damages are noticed notify an authorized service for
exchange.
Before connecting the pellet stove to the power supply check carefully:
•Whether the characteristics of the electrical supply match the requirements
indicated on the label of the pellet stove.

Installer / Service Manual BURNiT PM Comfort
Plus
12 –ЕN
•Weather the connection is correctly grounded.
• The cable must not be with temperature higher than 75°C.
• In case of direct connection to the power supply – contact an authorized electrician
to perform the action.
• Turn off the pellet stove from the power supply when the product is not intended
to be used for a long period of time.
The connection with the power supply must be easy to access in order to be able to
easily disconnect the plug in case of accidents.
4. Fuel
ATTENTION! Pellet stove is tested only with wood-pellets with diameter 6-8 mm,
class EN plus A1, according EN 14961:2011.
Use only the fuel indicated in this manual! Otherwise the warranty will be void.
All pellets are biomass manufactured from common low-growing plants and trees.
The most common household type pellets are made of sawdust and milled wood
chippings which are waste material from wood used in the production of logs,
furniture and other products. Wood is the richest raw material which does not have
any impact on the production costs of food products or ethyl alcohol (ethanol). The
raw material is processed under high pressure and temperature and is pressed to
produce small-size cylindrical pellets. The production process may utilize soft wood
material (such as softwood, pine), hardwood (oak) as well as recycled waste wood.
Wood pellets are produced in hammer mills or wood pellet plants.
Advantages of wood pellets:
Convenient storage. Pellet bags can be stored on a small area in a dry garage,
basement, service room or shed.
Easy loading. In most cases the boiler hopper needs loading only once a week –this
depends on the hopper capacity.
Better control of fuel quantity. The small size of the pellets allows for precise fuel
feeding. On the other hand, the supply of air for reaching optimal combustion
efficiency is easier to adjust since the fuel quantity in the combustion chamber
remains constant and predictable.
Fuel efficiency. High combustion efficiency is also determined by consistently low
moister content of pellets (consistently under 10% as opposed to 20% to 60%
moisture content of the logs). Low moisture content, controlled fuel portions and
precise air setting means high combustion efficiency and very low carbon oxides in
the flue gases.

When purchasing pellets, ask for conformity declaration and certificate issued
by an accredited laboratory and make sure the fuel meets the requirements
indicated in the manual. If you purchase large amount of pellets (bulk supply
for the entire heating season for example), ask your supplier to provide
accurate and true information about the storage conditions.
We recommend to use pellet with size of 6 - 8 mm. Density 600 - 750 kg/m3heating
value 4.7-5.5 kWh/kg. Ash content –less than 1% and moisture content up to 8%, EN
14961-2:2011.

The optimal density of the pellets which guarantees their quality is 605-700 kg per
cubic meter.
Pellet moisture content must not exceed 10%. Make sure you store your fuel in a dry
and well-ventilated place. The optimal pellet ash content is ≤ 1%. This also provides
for less frequent cleaning intervals for the burner.
