Vent Type

Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.

Direct Vent (121)

Configuration

Orientation describes the direction that air will flow through a piece of equipment. (e.g. air will flow horizontally through a "Horizontal" unit heater.) Most equipment will only function properly if installed in the proper orientation.

Modulating/Staging

Stages are unique speeds or levels that equipment can operate at. More stages allow for better fine-tuned control of output, which improves comfort and efficiency. Modulating equipment can operate across a range of levels, giving the highest level of fine-tuned control. Learn More
