Consult the rating plate on the furnace for gas type before installing. .wsite-menu a {} Only condensing furnaces are able to achieve the highest AFUE ratings of over 90 percent, with some reaching over 98 percent. The PVC pipes are used for air intake, exhaust gas, and to remove the corrosive condensation resulting from the combustion process. Condensing furnaces, like many conventional furnaces, use a draft-inducing fan and pressure switch. ) This control contains the. A heat-recovery ventilator, or HRV, is an optional device separate from the furnace that works as an air-to-air heat exchanger. See the unit wiring label or Figure 19 (page 30). A high efficiency gas furnace has AFUE ratings of 90% or higher, up to a maximum of 98.5% AFUE. In high-efficiency models, the lower temperature of the exhaust can allow moisture (a by-product of combustion) to condense in the flue, especially when outdoor temperatures drop into the 20’s or below. Like a conventional furnace, it takes in cold air from the house and runs it through an air filter; it moves the air with a circulating fan; and it has a gas burner with electronic ignition (although condensing furnaces may … | High efficiency gas furnace, Hvac furnace, Gas furnace. High-efficiency (92 percent and higher) condensing gas furnaces are complex. With condensing furnaces, it is common to find at least a two-stage (dual-stage) burner gas valve, which has electronic controls that allow the burner flame to be at either high or low settings, depending on the level of heat required. var STATIC_BASE = '//cdn1.editmysite.com/'; The main difference between a conventional and condensing furnace is how the furnace handles the exhaust gases from the combustion process. If the limit switches are closed, the the warmup time for the HSI begins. How a High-Efficiency Condensing Furnace Differs .
