The robust and durable combustion chamber has a 100% premium stainless steel construction, heats up more quickly, and helps in maintaining a more even temperature in the home. The secondary tubular heat exchangers are 100% welded one-piece , no bolts. and fasteners. The heat exchanger provides stainless steel baffles to maximize heat transfer from the heat exchanger. The tubular design of the secondary heat exchanger provides maximum thermal exchange. Due to low air restriction these appliances are compatible with today's high efficiency heat pumps or air conditioning systems.These furnaces come with high efficiency ECM blower motors. Safe and easy to use electronic controls - control the burner operation and speeds of the fan motor - provides on-board connections for optional electronic air cleaner, humidifier, and A/C systems. High efficiency oil burners enable high static pressure burners that offer a better control of the combustion excess air allowing for a cleaner and more efficient combustion.
