Safety precautions
Do not start the burner before it is connected to the boiler and the boiler is connected to the
chimney.
It is recommended to wear a respirator while handling pellets.
The boiler room where the burner is installed must fulfill all rules and recommendations given by
authorities.
All electrical connections must be done by trained professionals.
No flammable materials must be stored near the burner.
Warnings
Changing the construction of the burner without written permission from the
manufacturer is forbidden.
Use only spare parts provided or approved by the manufacturer in order to avoid any
damage to the burner and dangers resulting from it
Welding is allowed only after disconnecting the burner from electric supply. The circuit
board must be removed from the burner.
Do not open any boiler door while the burner is in operation.

PV 100a
Description
PV 100a is a pellet burner that is intended to be used with 6 or mm wooden pellets. You cannot use
any other fuel to run this burner.
The unique construction of PV 100a allows it to be used with different boilers: liquid fuel, solid fuel
and universal boilers. The PV 100a burner is connected to the boiler with a 129 mm flange (similar to
oil burners).
The burner is equipped with a safety thermostat, a melting chute, temperature sensor and auxiliary
battery for protection against back-burning.

Fuel
PV 100a uses premium wooden pellets as fuel. Wood pellets are concentrated and homogenized
fuel made from sawdust and cutter shavings. Pellets are pressed with high temperature. No extra
materials are added, pellets are held together by a natural ingredient found in wood – lignin. Pellets
are CO2-neutral, renewable fuel. Pellets must be stored in a dry and ventilated room. It is
recommended to wear a respirator when handling pellets.
Refilling must be carried out before the storage runs empty. In case it happened, burner has to be
restarted and the loading time can be up to 20 minutes that external auger has enough time to refill
itself.

Installation
You will need the following tools in order to install the burner:
•Spanner no. 13 for fixing the flange of the burner to the boiler
•Spanner no. 10 for connecting the body of the burner with the burning camber and fix the
bottom grate holder
•Cross-head screwdriver for fixing the cover of the burner
•6 mm hex wrench for fixating the boiler to the flange
In order to install the burner, the boiler must correspond to the following requirements:
•The door of the boiler must have a 130 mm opening (placement opening for the oil burner).
•The thickness of the boiler door must be less than 90mm
•The construction of the boiler must make it possible to open the door of the boiler with the
burner connected and removing ash from the furnace. If the door of the boiler is too narrow
for opening it with the burner, then extra hinges must be installed.

PV 100a
•If there is not sufficient (less than 5Pa) negative pressure in the furnace, a draught fan should
be installed for the exhaust gases.
•The boiler room where the burner is installed must fulfill all rules and recommendations
given by authorities.
•The boiler must be positioned in a way that there is enough space for cleaning the burner,
the boiler and the smoke pipe and removing the ash.
If flue gas temperature at the top of the chimney is less than 0Co, there is a risk of condensation. In
this case a pipe should be installed throughout the length of the chimney.
Note: It is recommended to use a flue gas analyzer for adjusting the burner. The burner must be
adjusted using the flue gas analyzer also when you change the size or the quality of the pellets.
Boiler requirements
Pellet burners need regular cleaning and therefore boiler construction must allow the door to be
opened without removing the burner. The minimum size of opening in boiler depends on the
position of door hinges and vice versa. Figure 3 below illustrates the situation. Point C is critical.
In order to keep door width minimum and boiler opening small, a double hinge solution can be used.
As double hinges add another degree of freedom, door must be fastened on both sides. Slide-out
doors with guide rails is also an option.

Burner is mounted to door using supplied oil burner flange. Bolt hole circle diameter and bolt sizes
can be customized by using custom flanges. D1 and D2 given in Table 3 are only valid with supplied
flanges.
