Baxi 700 IG
The Baxi 700 IG modulation forced draft gas burner is designed for installation on gas heating boilers of the Geodis series for domestic use. Thanks to the modulation of the flame, the burner operates quietly and with a minimum amount of harmful emissions of combustion products into the atmosphere, which is confirmed by the CE mark "Blue Angel": it practically does not produce CO (less than 5 mg / kW * h), and NOX emissions are two times lower European standards and are less than 35 mg / kW * h.
The burner is equipped with a variator, which, by changing the speed of the air fan, allows the rated power to be reduced by up to 60%. Thus, the power range of the device can be changed from 25 to 42 kW.
The 700 IG is equipped with a pneumatic system to maintain an optimum gas-to-air ratio. Fuel consumption is determined by the need for heating and / or hot water, and a special membrane in the gas valve supplies it depending on the fan speed, which allows maintaining optimal combustion and high efficiency (up to 95%) in all modulation modes. The burner has electronic ignition. To exclude the ingress of gas into the room, an ionization control of the presence of a flame is provided.
The 700 IG burner unit remains operational (does not block or shut down) over a wide enough gas pressure range. For example, at 7.5 mbar at the gas valve inlet, combustion does not deteriorate and power does not drop. Work continues up to 3 mbar. Only if the pressure gets even lower will the burner shut down. This property is especially important for areas where there is a problem of constant pressure drop in the gas pipeline.
Natural gas is used as fuel by default. Switching to liquefied gas is relatively simple - you just need to put one jumper and make a software reset. It is advisable to entrust this to a qualified specialist.
The model has a compact size, modern design and a wide range of accessories.
** Features: ** ionization control of the presence of a flame, gas pressure stabilizer, variable speed fan, complete premixing of gas and air, low noise level, environmental friendliness.
