PV50b pellet burner

3 Installation

3.1 Prerequisites

Following tools are needed 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

Cross-head screwdriver for fixing the cover of the burner

4 mm hex wrench for fixing the boiler to the flange
Warning! If flue gas temperature at the top of the chimney is less than 80C
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
In order to install the burner, the boiler must correspond to the following requirements:

The door of the boiler must have a 90 mm opening (placement opening for the oil burner).

The thickness of the boiler door must be less than 100mm

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.

If there is not sufficient (less than 5Pa) draught 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.
Pellet burners need regular cleaning and therefore boiler construction must allow the door to be opened
without removing the burner. The minimum boiler opening radius 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.
