44,000 BTU 80% AFUE Single Stage Multi-Positional Gas Furnace
The ACiQ 44,000 BTU 80% AFUE Single Stage Multi-Positional Gas Furnace is an affordable furnace option designed to provide reliable comfort for your home. With a basic efficiency rating, it is capable of adequately heating your space even during the coldest parts of the year. This model features a 44,000 BTU input and operates at 80% AFUE (Annual Fuel Utilization Efficiency), meaning 80% of the fuel consumed is converted into usable heat while 20% is lost through the flue and standard furnace operations. This results in an output of 35,200 BTUs. As an 80% efficiency furnace, it requires metal flue venting; if you prefer PVC or plastic venting, a furnace rated at 90% or higher efficiency is needed.
The ACiQ 44,000 BTU 80% AFUE Single Stage Multi-Positional Gas Furnace is typically suitable for small homes in ideal conditions and offers flexible installation options. Its multi-positional design allows it to be installed in upflow, downflow, or horizontal configurations, enhancing its adaptability for various home layouts. It includes a single-stage burner paired with a multi-speed blower to maintain consistent indoor temperatures. The furnace also features onboard self-diagnostics for easy troubleshooting and maintenance.
While this unit comes configured for natural gas, it can be field-converted to propane with an optional LP conversion kit, available separately. However, it is important to note that the N80MSN0451412A is not Low NOx or Ultra Low NOx compliant. If shipping to California, a mitigation fee may apply. Additionally, this model is not designed for use in mobile homes unless specified otherwise. Its durable outer casing ensures long-lasting performance, offering dependable comfort for years to come.
This gas appliance must be installed by a trained and qualified technician. Incorrect installation of gas lines, flue connections, or venting can lead to serious injury or even death. By purchasing this unit, you confirm that a trained professional will be responsible for the installation. We are not liable for any personal injury or property damage resulting from improper installation or service. The individual performing the installation or maintenance assumes full responsibility for any associated risks. Please note that many local jurisdictions require a licensed professional to install this type of equipment.
