Product review
Polar 2500 chimneyless heater, 10KN model
General description:

The working mechanism of this product is based on the combination of city gas or oxygenated liquid in the air and the result of this reaction is carbon dioxide gas and water vapor in addition to a significant amount of heat. If the reaction is incomplete, it can cause the production of carbon monoxide gas, so the design of gas heaters is important. It is very high, so the pressure settings and the amount of gas and air in these products are considered completely fixed and unchangeable.

In gas heaters, without the need for a chimney, there is no connection of the device to the outside of the living environment, and the products of combustion are spread in the environment directly and with the help of a reflector, the heat transfer is by convection and radiation (in the ceramic type), the gross efficiency of this device It is close to 100%.
Functional description:

The gas enters the heater through the pipe, and after the pilot path is opened and the thermocouple is heated, the main gas path to the burner is also opened, and after mixing with the primary air, the gas enters the burner and ignites, then it combines with the secondary air and creates a blue flame with complete combustion. As long as there is a flame, the thermocouple is hot. remains, the original gas path remains open, but as soon as there is any disturbance in the flame, gas cut or thermocouple failure, the gas path is closed to create the necessary safety. Also, this product is equipped with an ODS type safety system, this safety is such that if the oxygen level When the environment becomes less than 18%, the gas supply is automatically cut off so that the amount of oxygen in the environment does not fall below the permitted limit. At this time, the amount of toxic polluting gases such as carbon monoxide (CO) is also within the permitted limit, so there is no danger to the consumer. It does not threaten us, the torch of this heater is placed inside the reflector so that all the heat is directed towards the effect and the back of the heater does not heat up, and it can also be installed on the wall.
The main components of the Polar 10KN chimneyless heater

Flame monitoring system: This system includes a pilot and thermocouple, which, while lighting the main burner of the product and creating STAND BY conditions, is responsible for monitoring the correct operation of the flame and preventing risks caused by carelessness or gas disconnection.
Ambient oxygen reduction monitoring system (ODS): This system is a type of pilot with very precise settings, which shuts down due to the reduction of ambient oxygen and blocks the steam passage. Normally, the ambient oxygen makes up about 21% of the air, when due to the closed air inlets and lack of proper ventilation, the oxygen level is less than If it decreases from 18%, it will cut off the gas flow. At this time, the amount of carbon monoxide is less than 200 ppm, which does not cause any danger to the consumer.
Gas pressure adjustment governor: This governor is aimed at adjusting the gas pressure to the heater and creating optimal fuel conditions and correct operation of the ODS pilot installed and gas inlet or combined with the control valve.
Multi-functional control valve: This control valve (carburetor) has flame monitoring mechanisms, electric ignition (piezoelectric) and flame regulation, and it can be manual or thermostatic, in the thermostatic type, the flame of the heater increases and decreases based on the pre-set temperature and reduces energy consumption.
Grill (metal protection): In order to prevent injury due to burns (especially for children), a metal grid with a stainless coating is installed in front of the heater, which prevents hands from reaching the hot parts of the heater.
Gas inlet strainer: In the gas inlet to the heater, a suitable strainer is installed to prevent impurities from entering the pipe, this is especially important for the ODS pilot, and it prevents the orifice (hole) from clogging and the pilot from shutting down.

Can be used in:

It is suitable for homes and living environments with safety precautions, so this heater should not be used in bedrooms or smaller environments.
Suitable for public environments such as stores, banks, offices, universities, sports halls, restaurants, mosques, meeting halls, etc.
Can be used on the wall or on the ground
It can be used in any geographical climate.
