The York GY9 furnace is a single-stage high-efficiency furnace with an AFUE rating up to 92 percent. It is Energy Star-qualified, has earned the Good Housekeeping Seal and can be used in homes and commercial locations.
With downflow or horizontal applications, this furnace can be vented through a sidewall or roof with a single-pipe or two-pipe vent. The GY9’s size of only 40 inches allows it to be installed in many locations throughout the home while remaining easy to access for maintenance since the control box is located in the front of the unit.
The primary heat exchanger features a tubular aluminized steel design with few parts and a simple path for gas flow. The secondary, condensing heat exchanger is manufactured from durable stainless steel. The cooling SEER is improved by the blower-off delay and efficiency is improved by the electric hot surface ignition. Safety features for the GY9 include a 100 percent shut-off main gas valve and protection from intake, exhaust or condensate blockages.
