Preparation for operation

A solid fuel boiler (TTK) is a kind of heating apparatus that ensures a room is heated by burning firewood, coal, or pellets. No matter which model is selected or how the principles of its operation are applied, adherence to specific installation guidelines is required.

How to protect the room and where it is better to put

There are currently no restrictions on where a structure can be located in a private or residential building. Certain experts advise considering the guidelines provided in SNiP’s "Boiler Primes" section when installing. Nonetheless, it is more likely that the information in the document contains strong units.

It is highly advised that you consider the following criteria when selecting a location:

  • All pipes of the heating system should freely go out of the selected room and distribute throughout the house or apartment;
  • The room should be well ventilated and isolated;
  • It is forbidden to install models in the bedrooms, especially in children"s;
  • Installation is allowed in the corridor, kitchen;
  • Free access from either side should be provided to the device;
  • The ideal option is the construction of a separate extension from foam blocks;
  • It is allowed to install boilers in an outbuilding or separate boiler room;
  • The structure is mounted closer to the outer wall;
  • Ahead of the unit should be at least 100 cm of free space, from behind and on the sides of at least 60 cm.

The device operates more easily and safely when it complies with recommendations.

Setting up the location is just as crucial. In order to install TT, the concrete base must be poured beforehand, and a hole must be punched for the chimney and ventilation. The room’s walls ought to be fire-resistant. You can use asbestos cement, thin metal leaves, or any other non-combustible material to finish them.

If wooden slabs are used to decorate the space, they can be covered with metal sheets rather than being cleaned. It is also necessary to place a metal protrusion measuring 80 cm on each side of the boiler. By doing this, the floor will be spared from the burning fuel particles that shoot out of the boiler. If more electrical equipment is added to the space, the floor will need to have a common concrete screed installed to prevent unintentional fires.

How to do ventilation

You can turn on the ventilation equipment after setting up the area and deciding where to install the heating device. This stage cannot be avoided since using coal or firewood entails producing a lot of smoke and dust.

You must construct two windows with grilles in order to allow unrestricted access to cold air and hot outflow. The exhaust is tiny and is situated in the upper portion of one of the room’s walls. Slightly larger, the supply window is situated in the bottom half of the wall opposite or next to it.

It is not advised to place the ventilation window above the boiler, although this is sometimes the case. A gap beneath the door leading to the living rooms can function as a supply opening.

The boiler connection schemes

Following the necessary preparations, the device is installed. Before handling the task yourself, it is preferable to consult with an expert or entrust it to professionals in the field.

Stages of connecting the boiler to the system

The process of installing heating equipment is divided into multiple steps. Experts advise you to follow the order exactly in order to achieve the best outcome.

The following is the action algorithm:

  1. Preparation of the foundation on which the device will stand.
  2. Protection of walls and ceiling, mounting ventilation windows to ensure gas exchange.
  3. Connecting safety elements and inserting pipes going to radiators. The connection diagram is individual for each room, it is developed by experts.
  4. Installation of the chimney and generator, if the boiler requires connection to the power supply system.
  5. Water pumping into the system, identification of leaks and malfunctions.
  6. Checking the position of all shutters on the device and chimney.

After that, you can begin trampling and laying fuel.


For solid fuel models, the gravity heating system is thought to be the best choice—especially in a private residence. Installing it is simple and doesn’t require any special equipment. It is independent of the electricity source, which is crucial when installing in communities far from cities.

An additional pump is not necessary for this type of system because it is usually installed in an open manner with the expansion tank placed much higher than the heating device and all of the room’s radiators. This allows the coolant to spread through the pipe naturally through gravity.

To allow for free water flow, it’s critical to make sure that all radiator pipe angles are normal.

The system has a number of drawbacks.

  • the need for regular watering into an expansion tank due to its rapid evaporation;
  • air enters the system, which causes corrosion of the inner layer of pipes;
  • uneven distribution of the coolant over all radiators.

Notwithstanding these drawbacks, the system is widely used and well-liked.


Thanks to a unique pump, the forced system is far more practical and simple to operate, ensuring that the coolant is distributed uniformly and that every radiator has the same temperature.

It is positioned close to the expansion tank or bursts through another section of the system, continuously distributing water through the pipes so that it evaporates more slowly and doesn’t boil—a crucial feature if the heating apparatus lacks a thermostat.

When utilizing the forced system, there aren’t many requirements for the tank’s installation location. It also doesn’t matter how the pipes exiting the radiator slope.

Step -by -step installation of a heat generator and chimney

The heating system’s DIY installation components are not difficult to install, provided the room and the location of the design are properly prepared.

There are multiple steps in the step-by-step installation instructions:

  1. Installation of the device and aligned it vertically using metal linings or special legs. It is necessary to take into account the ratio of the pipe and the holes prepared for the installation of the chimney.
  2. Prepare several insulated pipes or take the usual, wrapping them with a bazal fiber.
  3. Make a hole in the wall, which will be 35-38 cm wider than a chimney pipe.
  4. Install the passage box from the metal, through it to skip the pipe, fill the remaining space with basalt cotton wool.
  5. Outside, the chimney is installed vertically, parallel to the wall. A peculiar umbrella is joined from above, warning a large amount of water, from below – a collection for condensate.
  6. Part of the chimney coming from the heat generator is mounted at a slight angle in its direction.

It is important to check that the chimney is not below the roof’s skate and that water will not leak into it from rain or melting snow after the work is completed.

The first heating of the boiler

It is permitted to begin utilizing the device for its intended purpose after inspecting the heat generator and all valves for leaks.

It is advised that the first heating be done in the room where TTK is located with a door or window open. An unpleasant smell that comes from burning a thin layer of production oil that is left on the device or other parts may be released while it is operating.

When starting a fire for the first time, the firebox needs to be fully loaded and the minimum combustion time is 60 minutes. You should check the chimney before ignoring.

We’ll go over everything you need to know about safely and effectively connecting solid fuel boilers in our guide. We’ll start by going over various connection configurations and describing the best way to connect your boiler to your heating system. Next, we’ll discuss important safety precautions to make sure you’re using your solid fuel boiler safely. We’ll walk you through the steps to keep your house safe and warm, from regular maintenance checks to adequate ventilation. So, our guide has everything you need, regardless of whether you’re new to solid fuel heating or just want to review safety procedures.

Safety measures during operation

You should closely read the instructions for using a solid fuel boiler in order to avoid mishaps and other issues.

These are the fundamental guidelines:

  • avoid close contact with a functioning device;
  • Do not leave plastic buckets, wooden or other flammable objects near the heat generator;
  • Do not leave the device unattended;
  • prevent the complete evaporation of the coolant during burning in order to avoid corrosion and rupture of pipes, as well as radiators;
  • adjust the air supply to the fuel using the door blown;
  • Do not put various objects on the boiler;
  • when boiling water in the system, close the chimney flashes and blew to prevent complete evaporation of water in an expansion tank and pipes;
  • Timely fill the tank with water.

If you can install a closed forced system, it’s worth it because it will make equipment operation easier.

Rules for cleaning and caring for a boiler and chimney

TTK needs to examine its condition if there is a decrease in heat transfer. Maybe it was because of his soot pollution. In order to clean the walls, one must wait for the entire structure to cool down, then open the lattices and blow any accumulations away using a metal poker.

Fuel residues collect soot and must be cleared in order to reload the chamber. Cleaning the chimney on your own is challenging, particularly if there are multiple bends. As soot and condensation build up on its walls, traction deteriorates and the chance of fire rises.

Cleaning is done once or twice a year, depending on the fuel type and operating mode. Hiring professionals to complete the work will help to prevent accidents and other issues. High heat transfer and a long system service life are provided by the cleaned boiler and chimney. Link to study on liquid thermal insulation.
