Description
The Lennox 27M18 is an essential component of Lennox HVAC systems, more specifically, it serves in the gas furnaces. It is a small component or a piece that is well designed and manufactured, and it is called an orifice. An orifice regulates the rate at which gas passes through a specific region in the furnace by narrowing the passage way. This controlled flow of the gas is required in the management of the burner flame size and the efficiency of the combustion. Through accurate control of gas flow orifice plays a role in fuel consumption and in the smooth running of the gas burner in Lennox furnaces which in turn means efficient heating and may imply lower fuel bills.
