What must be ensured when installing a gas furnace regarding air intake?

When installing a gas furnace, it is essential to ensure that there is proper air intake for combustion. This is crucial because gas furnaces rely on a specific mixture of gas and air to operate efficiently and safely. Adequate air intake allows the furnace to draw in the correct amount of oxygen needed for the combustion process. If the air intake is insufficient, the furnace can produce incomplete combustion, leading to an increase in carbon monoxide production, reduced efficiency, and potential safety hazards.

Moreover, proper air intake helps maintain balanced pressure within the furnace system, preventing issues like backdrafting or affecting the overall performance of the heating system. Ensuring proper air supply not only optimizes the furnace’s efficiency but also enhances safety for the occupants in the building.
