All welds are made using automatic welding machines. Specially designed turbulators are installed inside the heat exchanger pipes, which ensures the maximum possible heat transfer from gas combustion products to the coolant, rapid heating of the coolant and maximum efficiency - 93% of the AOGV boiler.
In the production of floor-standing boilers AOGV Ross, components from European manufacturers are used:
Gas automatics EVROSIT (Italy), MERTIK MAXITROL (Germany);
Expansion ELBI (Italy);
Circulation pumps WILO (Germany);
Burners Polidoro (Italy);
Heat exchangers IMAR and Giannoni (Italy),
Air vents, safety valves, thermostats, sensors, thermometers and pressure gauges Compini Corel, ICMA, T&G (Italy).
To maximize heat transfer from gas combustion products to the coolant, specially designed turbulators are installed inside the heat exchanger pipes. This ensures rapid heating of the coolant and achievement of maximum efficiency - 93% of the AOGV boiler.
The use of special plate burners provides uniform, and therefore higher quality, combustion of gas in the combustion chamber at various combustion modes and ensures effective heating of the entire surface of the heat exchanger.
Fig.2. Basic elements of floor gas boiler AOGV Ross
This model of the device is distinguished by a universal chimney with the ability to regulate the draft break (in models with a power of up to 40 kW, combustion products are discharged vertically or horizontally).
Models of Ross boilers with domestic water heating (DHW) use a copper water heater coil mounted in the main heat exchanger.
Selecting a room
The most optimal place for installing a Ross gas boiler in a residential building or apartment there is a separate special small room of appropriate volume with a window, window or transom, chimney duct, supply and exhaust ventilation.
For a device with a power of up to 30 kW, installation in the kitchen is possible. According to current regulations, installation in bathrooms is not permitted.
The device with a thermal power of up to 30 kW can be installed in rooms with a volume of at least 7.5 m3, not intended for permanent occupancy of people (in auxiliary premises), where the total duration of stay of people during the day does not exceed 4 hours.
The height of the room in which the boiler is installed must be at least 2.2 m. A device with a thermal power of 30 kW or more requires a separate special room with a volume of at least 13.5 m3.
The walls and floor of the room must be fire-resistant and must not be a source of dust. The best decision- This is covering walls and floors with ceramic tiles or coating with oil paint.
It is unacceptable to carry out work that produces dust while the device is in operation. This leads to the deposition of contaminants on the burners, in the heat exchanger channels, on the turbolizers and to the automatic shutdown of the boiler or to such a decrease in the amount of air required for normal combustion that soot appears, which interferes with normal operation.
When installing a Ross floor-standing boiler in kitchens and residential buildings, designed to operate on gas fuel with the removal of combustion products into chimneys, microconcentration control should be provided carbon monoxide(CO) and control of pre-explosive concentrations of natural gas by installing apartment (household) alarms.
These requirements do not apply to heating equipment with a sealed combustion chamber, in which combustion air is taken in and combustion products are removed through outer wall building.
Installation and installation of Ross boiler
The Ross AOGV floor-standing boiler is connected to the gas supply network through a gas filter. The tightness of the connection is checked using the soaping method. Prohibited use open flame to check the tightness of the gas circuit.
The device is installed on a fire-resistant base no closer than 0.5 m from combustible structures and no less than 0.1 m from non-combustible ones. Furniture and other flammable objects must not be placed closer than 0.5 m from the apparatus. The free space in front of the unit must be at least 1.25 m.
For normal operation The following devices, which are not included in the delivery package, must be installed in front of the device:
Water and gas purification filters;
Water softening device;
Voltage stabilizer (for volatile devices);
Device uninterrupted power supply(for areas where long-term power outages are possible) (for volatile devices).
All installed devices must be in good working order and function normally.
Connecting the Ross boiler to the chimney
Installation of a Ross AOGV boiler is permitted only if there is a chimney to discharge combustion products into it. The quality and efficiency of the device depends on what material and how the chimney is made. The cross-section of the chimney duct must be no less than the cross-section of the smoke outlet pipe.
The height of the chimney above the roof is set depending on the distance to the roof ridge (Figure 3). If there are higher parts of buildings or trees near the chimney, then it should be installed above the boundary of the “wind pressure zone”.
The chimney channel must be strictly vertical, smooth, even, without turns or narrowings, dense, without cracks. The connection point of the device to the chimney pipe must be sealed.
Due to the fact that modern economical boilers Ross with high efficiency have low temperature weekend flue gases and operate in automatic intermittent (periodic) mode with a constant temperature difference, the chimney does not warm up well and aggressive condensation can form in it, which leads to low-temperature corrosion (erosion) of the chimney.
At insufficient thermal insulation chimney, in order to protect it from the harmful effects of condensation and destruction, you can use special inserts made of stainless acid-resistant steel or use special double-walled heat-insulated chimneys made of corrosion-resistant steel to remove combustion products.
Fig.3. Chimney placement
The chimney must ensure the removal of combustion products in all weather conditions. Before turning on the device and during its operation, it is necessary to check the presence of traction.
With normal draft, the match flame will be drawn into the combustion chamber and go out. To maintain economical and uninterrupted operation gas floor-standing boiler AOGV Ross, it is necessary to systematically clean the chimney and gas ducts of the device from soot and blockages.
During the initial inspection and cleaning of chimneys and ventilation ducts The following must be checked: compliance of materials, absence of blockages, density, serviceability and correct location of the head relative to the roof and structures located nearby, the presence of normal traction.
IN winter period At least once a month, home owners must inspect the chimney head to prevent freezing and blockage.
In a boiler with forced draft and closed camera Combustion air is supplied and exhausted by a fan through a coaxial chimney.
Coaxial chimney often called “pipe in pipe”. By inner tube In such a chimney, combustion products are removed to the street using a fan, and combustion air enters through the outside.
The single-circuit gas boiler Ross AOGV-16 is intended for heating premises equipped with water heating systems with water that has undergone water treatment. It is used for continuous operation.
The double-circuit unit additionally allows for heating water for household needs.
The operating principle of the boiler device is based on heating the coolant (water) located in the heat exchanger due to the combustion of gas in the combustion chamber of the device.
The AOGV-16 device runs on natural gas GOST 5542-87 with a pressure of 1274+100 Pa and automatically maintains the temperature set on the automation unit.
Fig.8. Construction of the Ross AOGV-16 gas boiler
The Ross-16 boiler consists of the following parts (Figure 8), described below.
Heat exchanger (1) is an all-welded cylindrical body, in the lower part of which there is a combustion chamber (6).
Pipes through which combustion products pass are welded inside the heat exchanger body. Turbulators (7) are installed in the pipes, increasing the efficiency of heat transfer from combustion products to the coolant (water).
A gas automation unit (2) is installed in the lower part of the front wall of the heat exchanger. The pipes (11) are used to connect the heat exchanger to the heating system.
A glass (9) is welded into the upper part of the heat exchanger for installing a gas valve thermocylinder, and a ring (8) for installing a thermometer (10).
The heat exchanger is installed on the frame (5). In double-circuit models, a tubular heat exchanger for the hot water supply circuit, made of a copper tube or stainless corrugated hose, is additionally mounted inside the heating circuit heat exchanger.
To connect the hot water supply circuit, pipes (25) are used.
Block gas automation(2) consists of a gas manifold (12) mounted on a bracket. The plate burners are mounted on the same bracket.
The gas manifold (12) is connected to a multifunctional gas valve (14), which regulates the gas supply to the Ross-16 boiler depending on the required operating conditions.
The gas manifold has an outlet in which nozzles (15) are installed. The gas supply from the gas pipeline to the gas valve (14) is carried out using an adapter (16).
Each time the apparatus (boiler) is turned on, the burners (13) are ignited by the constantly burning flame of the pilot burner (17).
Multifunctional gas valve(14) ensures that the apparatus (boiler) is turned on and the set operating mode is maintained together with the thermocouple (18), draft sensor (20), pilot burner (17) and piezoelectric element (19).
To access the gas valve, you must open the front door of the appliance.
The piezoelectric element (19) is placed directly on the gas valve (14).
The multifunctional gas valve allows you to:
Turn off both the main and ignition burners - the control knob is in the “dot” position;
Light the pilot burner;
Put the device (boiler) into operation.

When the piezoelectric element button (19) is pressed, a spark is generated to ignite the pilot burner (17).
The combustion product collector (3) ends with a neck for connection to the chimney. A draft sensor (20) is installed on the combustion products collector (3).
To clean the heat exchanger, remove the casing cover of the Ross AOGV-16 boiler, then remove the combustion product collector (3).
The outer casing (4) consists of side walls firmly fixed to the frame, an opening front door and a removable top cover. To control the water heating temperature in the heat exchanger, a thermometer (10) is installed on the front panel.
The bed (5) is formed by two support brackets. The heat exchanger and casing are fixed to the frame. The frame has holes for threading handrails (22 mm in diameter) for moving and transporting the device.
An integral part of the frame is a reflector made of sheet steel (21), which significantly reduces thermal effect heat exchanger on the floor.

Reviews
Consumer reviews of Ross gas boilers are not always clear
The reviews about Ross studied by our experts are very ambiguous. Some consumers note the quality and sufficient level of reliability, which is achieved through the use of Italian components during assembly. There are positive reviews from users who have been using Ross gas boilers for several seasons. The company's floor-standing equipment is more in demand, while wall-mounted equipment is not of interest to customers.
Some users note a discrepancy with the declared power. It is also believed that European standards are not adapted to our conditions, which affects the quality of their work. Indicate the uneconomical nature of boilers with a cast iron heat exchanger. There are comments regarding the service; there are cases of long waits for delivery of parts to replace broken ones. Many point out the somewhat inflated price for Ukrainian-made boilers.
Price
