Norms for installing gas hinged boilers

The SNiP regulations set the fundamental guidelines for where gas boilers should be installed. Installing boilers in living rooms, bathrooms, basements, or attics is prohibited at the same time. A separate top-top is required for units that have a thermal capacity greater than 36 kW.

The following are the prerequisites for installing a floor gas boiler up to 60 kW in a wooden house from the beam:

  • The smallest volume of furnace – 15 m2. 1 m2 is additionally added for each kW of power in excess of the indicated power.
  • The furnace must have a supply and exhaust ventilation with a 3-multiple air exchange per hour;
  • Topic should have artificial and daylight. At least 0 should be located for 1 m2 of the area.03 m2 window openings.


Building planning must consider where the combustion will eventually be located in relation to the ceiling, walls, windows, and doors in order to ensure that it satisfies the minimum requirements.

When installing a gas boiler in a wooden house, the following signs are taken into consideration:

  • The base is placed at the deaf wall.
  • To ensure the required volume of air, the unit is placed by the front wall opposite the door, with a minimum distance of 3 m.
  • The smallest gap to the ceiling – 0.8 m.
  • The ceilings are covered with fireproof material.
  • The wooden floor is closed with thermal insulation material.

Fire safety standards for installation

The fire safety regulations that govern the installation of assemblies, gas equipment, smoke systems, and furnace rooms should be considered when installing a gas boiler in a wooden house.

Building materials that are not combustible should be used to construct the boiler room’s premises. Where the boiler and chimneys are located, a partial installation of fire-resistant surfaces is permitted if there is no comparable possibility.

In this instance, fire-resistant basalt heat insulators shield the floor’s base and walls. A specialized firewall is used to place flue channels through the roof and floor slabs.

Installation on different walls

Adherence to all fire regulations and manufacturer instructions is imperative when installing a boiler on a wooden house’s walls. Unit, you must provide a vertical and horizontal level and securely reinforce it against the wall.

Simultaneously, fasteners composed of various wall materials have different installation requirements, and the same is true for hollow walls.

Installation on the Wall Wall

The best material for a building’s walls where a gas unit is to be placed is reinforced concrete. These buildings have exceptional strength properties associated with the category of fire-resistant materials.

No special occasions are needed for the installation of the unit on such wall material. Steel anchors are used for installation, strengthening the national team in a sense before the unit is hung.

This wall works well for mounting heating appliances of any design or capacity, including dimensional models with integrated hot water tank drives.

Installation on a brick wall

The installation requirements of a gas boiler are laid out separately in the current regulatory directives for the installation of heating units on a brick wall. Brick and reinforced concrete are examples of fire-resistant building materials, so installing the boiler directly on the wall is acceptable.

However, at times the placement of the unit placement site must be carried out by gas service representatives who are in charge of granting access to the unit for operation. Plastering involves the installation of a mounting bar for a hinged unit. When the plaster is finished, two bolts that are used to install a gas boiler in a wooden house come out of the wall.

Is it possible to hang a boiler on a wooden wall

Fire safety regulations permit the installation of a gas boiler on a wooden wall, even though these walls are made of easily-hugging materials, as long as the heat-resistant substrate is installed beforehand.

It is advised to install a substrate from the following heat insulators in order to thermally insulate the aggregate from wooden walls:

  • Basalt cotton wool with a rigid base from a steel sheet on which a layer of material over 50 mm is placed.
  • Basalt tight leaf material.

They are completely capable of shielding the wall’s surface from the beam of fire in the case of an emergency involving the release of an open flame.

Fastening of the chimney of the wall boiler

The boiler model has a direct bearing on the regulations for chimney installation. Open firebox atmospheric aggregates run on natural thrust, while closed furnace device structures are connected to a coaxial type chimney that removes flue gases with a blowing fan and simultaneously creates a forced air fence. The distance between the boiler chimney and the location of the ridge or parapet determines the height of the chimney’s streaming:

  1. If it is not more than 1.5 m, then the pipe is installed with an elevation by 0.5 m above the parapet/skate point.
  2. If the distance is in the range 1.5-3 m, then its highest point should not be located below parapets.
  3. In the event that the gap is more than 3 m, the pipe is mounted so that its upper level is not lower than the line at an angle of 10 degrees from the ridge to the horizon.

Installation of a floor gas boiler in a wooden house

The enormous sizes of floor modifications necessitate a unique installation method in a wooden home. In the event that the owner of the large house chooses to install the floor structure, he must do so at the time of house construction because some boiler constructions call for the installation of both a separate furnace and a strong foundation.

The supply and exhaust ventilation device, which must provide three different circulations in the boiler location zone, as well as the presence of doors and windows in the room, are additional requirements for these devices.

Installation work

The factory of the manufacturer makes recommendations regarding how to connect a gas floor boiler; however, the work should only be done by specialized service providers who hold the necessary licenses to perform such work. The satisfaction of this requirement will be necessary in order to guarantee boiler equipment and issue a gas connection permit. The following are the prerequisites for installing boiler flooring in a wooden house:

  1. The base for the boiler is made of fire resistant material, usually from reinforced concrete.
  2. The boiler is placed in such a way that the passage distance between the structure and the wall can be used to maintain the unit: from the side and rear walls of at least 70 cm, in front of the front of the boiler 1.2 m.

The installation of chimneys

Holes are drilled in the roof, ceiling, and wall to install the chimney. Their area ought to be marginally larger than the chimney’s diameter.

The boiler’s output pipe has a steel metal adapter installed on it so that it can connect to the chimney. Following that, a tee and "revision" are positioned for the purpose of inspecting and cleaning gas traders. Fire safety must be given careful consideration in areas where pipes pass through walls and ceilings. Materials that resist fire are used to isolate these areas.

The chimney should be situated below the building’s wall at a negligible slope. This prerequisite is required in order to remove condensate that has formed in chimneys as a result of temperature differences. Generally speaking, the boiler’s factory instructions specify the calculated degree.

With clamps every two meters and brackets every four meters, the flowering device is completely strengthened to the exterior of the walls or ceiling coating. For the chimney to be displayed, a tip is required to guard against the atmosphere’s external effects.

Connection of the heating system

For single-circuit models, a more straightforward binding of the boiler is completed; only the supply and return pipelines of the intra-house heating network are summed up in them.

Among other things, cold water is also supplied for the DIS system for double-circuit units. Installing a mud or filter to purify water from sludge and corrosion products prior to adding network water to the boiler is advised for the boiler’s efficient and long-lasting operation.

In order to stop air flow in the heating system and make the process of fixing the gas boiler easier, the cutting reinforcement installs the cutting and return pipelines. The boiler unit’s connections should all be tightly sealed.

A scale-filtering water entry filter is fitted at the boiler’s entrance if the water is excessively rigid to avoid crushing on the boiler’s heating surface.

Install the expansion tank, circulation pump, airborne forces, and automation system sensors at the boiler reference points that the manufacturer and the executive thermal heat circuit have designated.

Gas line connection

Only experts from a gas supply company who have been granted special permission to perform the necessary work on gas equipment can complete this step.

Installing a filter on the intra-house gas pipeline is necessary to shield the boiler’s gas equipment from debris and condensate.

Before connecting the boiler safety automation sensors, new gas pipelines must be installed to ensure that the trash does not contaminate the burner device’s calibrated canals.

A gas meter and a valve-switch for the emergency shutdown of the boiler are placed in front of the boiler upon the entry of gas fuel into the home. Steel gas pipes with threaded connections are used to strap gas equipment.

Carrying out trial launch

The boiler is connected to its electric network once it has been bound to the gas and heating systems. It is advised to connect the boiler through a voltage stabilizer in order to shield electronic control units from mains voltage jumps.

Following the installation process, coolant is added to the heating circuit and the system with pressure 1 is turned off.5 from the boiler’s working pressure, but not higher than the manufacturer’s indicated indicator. The density of the gathered heating scheme is examined at this point.

A Gorgaz representative conducts the commissioning of the gas and the first launch of the gas equipment. Following successful test results, he grants the subscriber a permit for gas supply, at which point boiler equipment can be operated.

A floor gas boiler can greatly increase the comfort and efficiency of the heating system in a wooden house. Homeowners can experience dependable and consistent heating during the winter months by choosing a gas boiler.

The space-saving nature of a floor gas boiler is one of its main advantages. In contrast to conventional boilers, which can occupy valuable space in a house, floor gas boilers are usually installed below the floor, leaving more space available for other uses.

Additionally, installing a floor gas boiler in a wooden house is a fairly simple process. Homeowners can minimize any possible disruptions to daily life by ensuring that the boiler is correctly integrated into the current heating system with the assistance of a professional installer.

The energy efficiency of a gas boiler is an additional benefit. When compared to other heating systems, gas boilers are renowned for their capacity to produce large amounts of heat with minimal energy consumption. This makes your home more ecologically friendly and sustainable in addition to lowering utility costs.

To sum up, there are a lot of advantages to installing a floor gas boiler in a wooden house, such as its easy installation, energy efficiency, and space-saving design. Homeowners can minimize their environmental impact and enjoy dependable and comfortable heating by investing in a gas boiler.
