1.2 On Product
•Hereby we thank you for purchasing TOBY B boiler. TOBY represents one of the most sophisti-
cated solutions for automatic combustion of wood pellets to be found on the market. It is completely
adapted to burn wood pellet as a primary fuel, achieving maximum efficiency level up to 92 % and
a very low exit temperature for flue gases (below 160 ◦C). Emission levels of this boiler fulfill the
most rigorous norms of European countries.
Main features include:
1. New burner (patented design!) with primary and secondary air-flow to ensure best combustion
results and highest efficiency
3

2. Self-cleaning bottom of the burner to automatically remove the ash residues from the burner
pot
•Ignition, start-up and turning-off are fully automatized. Combustion control is optimized using
algorithms such as ‘modulation’ which automatically decreases pellet dose as the difference between
desired and reached temperature is decreasing.
•Boiler is easily connected to a room wi-fi thermostate.
•As required by the European norm EN 303-5 boiler chamber is made by welding 5mm thick steel
plates (all surfaces in touch with fire). Other parts are made of 4mm steel.
•Safety features:
Pellets are fed to boiler via internal transporter screw inside the storage tank. From there pellets
are fed over to heating chamber where they fall free to the designated combustion area (the ’actual’
embedded burner of the boiler). Storage and combustion area are physically divided. There is a
safety thermostat to prevent back-fire. There is also an anti-explosion safety device on the right
side of the heating chamber.

Boiler chamber is tested on test pressure of 6 bar in our own facility.
Pay strict attention that boiler valves are always open while boiler in use.
Don’t forget to do a mechanical reset of the circulation pump at start of every heating season.
8

Clean the boiler on a regular base.
An expert should be entrusted with the mounting of the heating and the initial operation.
This must be a person who will take over the responsibility and guarantee the correct operation of the
boiler and of the complete central heating system. In the case of an incorrectly planned system with
manifesting deficiencies caused by the respective person’s incorrect installation of the system, which can
again lead to an incorrect operation of the boiler, the complete liability for the material damage and
potential new costs arising in relation to it is borne exclusively by the person who was entrusted with
the mounting of the central heating system, and not by the boiler manufacturer, sales representative or
seller.
4 Safety remarks
While in use, some parts of the boiler may be hot. Don’t touch the boiler without appropriate
hand protection against heat.
If some parts of the boiler occur to be damaged it is strictly forbidden to continue using the
boiler.
Do not touch electrical wires with wet hands
Electric connections must be made according to 73/23 CEE i 93/98 CEE and properly di-
mensioned.
Use of the temperature relief valve is OBLIGATORY with this boiler to ensure safety in
heating systems using solid fuels.
5 Boiler placement
5.1 Boiler room
Room where kamin is placed, must posess ventilation windows.
9

Front side should have free access.
Boiler base must be stable and made of fireproof material.
5.2 Connecting to the chimney
TOBY H kamin is a boiler with natural draught so it requires a chimney not just to transport flue gases
out of the boiler but also to create negative pressure necessary for boiler function.
Boiler requires pressure drop of 10 Pa.
Chimney is to be connected as depicted below and it is necessary to clean the chimney 1-2 per year.
10

1) Flue pipe 2) Gasket 3) Fireproof protection cap 4) Chimeny dimater not greater than 200x200mm with
max height 5-6 metars.
5.3 Filling the system with water
Filling the system with water is to be done using the tap valve connection of the boiler.
When filling the system with water take care that no air remains in the boiler.
The filling process is done when no air is coming out through automatic air vent and pressure gauge is
showing the value between 1,5 and 2,5 bar (closed systems). Air vent is to be set at the highest point of
the (closed) central heating system. If the pressure is below 1,5 bar the filling process must be repeated.
For open systems, working pressure depends on the overall height of the system and the open expansion
vessel (1 bar for each 10 m is an estimate).
After the filling process is done, it is obligatory to close the drain tap valve, close the water supply to
the water-filling pipe and detach the water-filling pipe.
5.4 Connecting the boiler with a closed central heating system with circulation
pump on the return line
Recommended connection scheme is depicted below:
11

kazanu kotla (Poglavlje 1, Pozicija 18 na crtežu kotla).
It is essential to have a thermometer and a manometer installed to the system (Position 4 on
upper scheme)
14

It is recommended to install a dirt catcher and also an anticondensation valve on the return
line. (3-way mixing valve).
Please not that air-vent is not premounted with the boiler. It should be connected externally.
5.7 Use of temperature relief valve with obligatory filling
The temperature relief valve (shown below) must be present in the system. The valve must
be installed by a qualified technician in accordance with the instructions given in the manual from the
producer of the valve. We recommend the CALEFFI 544501 valve depicted below.
6 Return line protection against condensation
Every boiler is sensitive to condensation if the return line water temperature is too low. In order to avoid
it is necessary to mount the mixing valve to this boiler.
15

1. 3-end mixing valve 2. Circulation pump 3. Thermostate
The purpose of this valve is to transmit a portion of the hot water to the return line cold water in
order to compensate the temperature difference between the flow and return line.
7 Boiler cleaning and maintenance
Regular maintenance and cleaning of pellet boilers is necessary to ensure product functionality and long-
life operation.
Regular weekly cleaning consists of following operations (detailed steps are xplained in text below).
1. Emptying the ash from the bottom of the boiler (using the ash tray delivered with boiler)
2. Removing ash layers in the heating chamber if such
3. Cleaning the retort burner (round plate where pellets are falling in)
4. Cleaning the plate which is carrying the retort burner
5. Moving the bar in the heat exchanger of the boiler. This would force the ash to fall down from the
difficult-to-access heat exchangers area.
Occasional (seasonal) cleaning consists of regular weekly cleaning plus detailed cleaning of the heating
chamber from above.
How often do I need to clean the boiler? This depends on several factors, most important is the
quality and purity of the wood pellets used. Weekly cleaning has to be performed 1-2 per week, seasonal
cleaning 1-3 times during the heating season.
However if pellets of extremely bad quality are used, the cleaning frequency can change dramatically.
Boiler would not last long.
What tools do I need to clean the boiler? Simple cleaning set is delivered with the boiler. However,
ash-vacuum-cleaner would make things faster and easier.
Before performing any of the steps described below, boiler must be turned off and completely cold.
This is especially important for heat-exchanger cleaning. If they are still hot while bar is moved up and
down, they will be damaged.
It is obligatory to wear gloves for any operation described below.
7.1 Regular weekly cleaning
Necessary equipment: Gloves, Ash removing vacuum cleaner OR manual cleaning set (delivered with
boiler).
Open the outter main boiler door.
16

Open the lower, chamber door with the boiler KEY.
Release the upper mobile part of the burner pot.
Attention: Some boiler parts may be hot!
Clean the area around the burner.
Clean the area around the burner. If you dont have
a ash vacuum cleaner, use the manual tools that are
delivered with the boiler.
17

Burner is now free of ash.
Put the upper burner part back in place.
Release the screw-balls that hold the plate below.
Clean the area inside with the ash cleaner or using
manual tools. When screwing back the holders,
screw completely, so that no air can pass inside.
18

If no vacuum cleaner is present, use the hand tools
as shown below.
