Boiler Venturi / Gas-Air Mixer Replacement in Greater Vancouver
Blends gas and air in the correct ratio for clean combustion. Supplied and professionally installed by licensed gas fitters — never sold for DIY.
What the Venturi / Gas-Air Mixer Does
On fully premixed condensing boilers the venturi draws gas into the combustion-air stream at a precise ratio before it reaches the fan and burner. A blocked or cracked venturi upsets the gas-air mix, causing combustion faults and lockouts.
As the fan pulls air through a narrowing throat, the pressure drop draws in exactly the right amount of gas from the valve, producing the consistent mixture modern burners need.
We supply and fit the venturi / gas-air mixer as part of a complete boiler repair or new installation, and inspect it during annual maintenance for homes across Greater Vancouver.
