Turbo nozzle for Lemax gas boiler
In today’s article we will try to tell you what a turbocharger for a Lemax gas boiler is, what boilers it is suitable for, and we will try to answer the question that was left on our forum on November 2 by user Igor.
The turbo nozzle is designed to remove combustion products in a forced manner, which allows the use of gas boilers without a specially organized natural draft chimney. For boilers with a power of 10 kW, the chimney diameter is 100 mm. For boilers with power from 12.5 to 30 kW. chimney diameter 130 mm. For boilers with power from 35 to 40 kW. chimney diameter 140 mm. The product has a fan installed at a rated voltage of 220 V. 50 Hz
The turbo nozzle consists of a housing on which a fan No. 3 with inlet and outlet pipes is installed. A pressure switch (air pressure switch) item 4 is installed on the housing, connected to the fan by a tube. All electrical connections are switched through the terminal block, item 7.
1 – Turbo nozzle base. 2 – Turbo nozzle cover. 3 – Fan 4 – Monostat. 5 – Monostat connection tube. 6 – Smoke exhaust pipe. 7 – Terminal block.
Device and operation. The turbo nozzle control unit is designed for connection to boilers equipped with safety automatics SIT 820 NOVA and SIT 845 Sigma .
The turbo nozzle performs forced removal of boiler combustion products based on a signal from the thermostat (the thermostat installed on the boiler maintains the temperature at the level specified by the consumer). In this case, the pressure switch (air pressure switch) closes the contacts only when the air pressure at the outlet of the turbo nozzle corresponds to the specified parameter. If the pressure in the chimney exceeds or falls below the set limit, the contacts will open and the boiler safety circuit will break. In the event of an emergency stop of the turbo fan or when the flue gas outlet is blocked, the operation of the boiler stops, that is, the safety automatic SIT 820 NOVA (volatile boiler control unit) stops the gas supply to the main burner.
Chimney pipe placement: ? if there is no condensate collector, it should be installed at an angle to the ground, preventing condensate from flowing back. The optimal slope is 3–6°. ? the minimum horizontal distance to doors, windows and open ventilation grilles (openings) should be 0.5 meters; ? the minimum distance to the top edge of doors, windows and open ventilation grilles (openings) should also be 0.5 meters; ? the vertical distance from the windows located above the smoke duct opening is from 1 meter; ? in the area of 1.5 meters from the pipe there should be no obstacles, say, walls, pillars, etc.; ? each turn reduces the length of the pipe by: 0.5 meters - 45 degrees, 1 meter - 90 degrees; ? To avoid clogging and blowing out, it is mandatory to install a deflector on the chimney

Installing a turbocharger on a Lemax boiler
Igor November 2, 2021 “I bought a LEMAX boiler of the PREMIUM series with SIT 820 NOVA automation and a LEMAX turbo nozzle. I invited him from the gas boiler service center to start the boiler and connect the turbo nozzle to the boiler. The nozzle was connected, but not quite correctly. The nozzle fan runs constantly. When the main gas burner is turned off, the fan does not stop. I drew the attention of specialists to this, and they repeatedly tried to correct this situation. But to no avail. In the end they left me. I have a question - how to connect the nozzle so that the fan stops when the main burner is turned off? Thank you in advance for your advice."
