Honeywell 45900446-250 GAS Control Device
Manufacturer: HONEYWELL
Type: Gas control device
Model: 45.900.446-250
GAS/AIR ratio 1:1
The venturi manifold system is a gas/air mixing unit that allows modulation of a premix burner with constant gas/air ratio down
to 20 % of maximum load. It is to be used in combination with a fan and a Resideo 1:1 regulating gas valve.
The modulation is accomplished by changing the fan speed. The outlet pressure of the gas valve is regulated to ambient
pressure by the gas valve.
The venturi generates a negative pressure against the ambient by which the gas is drawn through the gas valve outlet.
Ambient temperature: -15 … 70 °C
Weight: 0.46 kg
