*Off Heating - This fan delay timing is adjustable (90, 120, 150 or 180 seconds). 150 seconds as shipped.

1.These furnaces are manufactured for natural gas operation. Optional kits are available for conversion to propane operation.

2.Minimum Circuit Ampacity calculated as: (1.25 x Circulator Blower Amps) + I.D. Blower Amps. Wire sizes should be determined in accordance with National Electrical Codes.Extensive wire runs will require larger wire sizes.

3Maximum Overcurrent protections Device refers to maximum recommended fuse or circult breaker size. May use time delay fuses or HACR- type circuit breakers of the same sizes as noted.

NOTES:

1.For elevations above 2000 feet the rating should be reduced by 4% for each 1000 feet above sea level. The furnace must not be derated, orifice changes should only be made if necessary for altitude.

2.The total heat loss from the structure as expressed in TOTAL BTU/HR must be calculated by the manufacturers method or in accordance with the "A.S.H.R.A.E. GUIDE" or "MANUAL J-LOAD CALCULATIONS" published by the AIR CONDITIONING CONTRACTORS OF AMERICA. The total heat loss calculated should be equal to or less than the heating capacity. Output based on D.O.E. test procedures, steady state efficiency times output.

AMH* specifications

The Amana AMH* series is a line of advanced air conditioning and heating systems designed to provide efficient climate control for residential spaces. Renowned for their innovative features and technology, these systems prioritize comfort, sustainability, and ease of use.

One of the standout features of the Amana AMH* series is its impressive energy efficiency. The units are equipped with high SEER (Seasonal Energy Efficiency Ratio) ratings, which indicate their ability to provide effective cooling while consuming less energy. This not only helps homeowners save on utility bills but also reduces their environmental impact, making the AMH* series an eco-friendly choice for climate control.

The Amana AMH* series incorporates state-of-the-art inverter technology. This technology allows the system to adjust its cooling or heating output based on the specific demands of the home at any given moment. Instead of operating at a single, fixed speed, the inverter-driven compressor can modulate its output, providing a more consistent temperature and improving overall comfort.

Additionally, these systems feature advanced refrigerant technology. They often utilize R-410A refrigerant, which is known for being more environmentally friendly compared to older refrigerants. This contributes to the overall efficiency of the units while minimizing harmful emissions, complying with modern environmental regulations.

Another notable characteristic of the Amana AMH* series is its noise level. Designed with sound insulation and advanced engineering, these units operate quietly, ensuring that the comfort of the indoor environment is not disrupted by excessive noise. This is particularly beneficial in residential settings where quiet operation is essential.

The user-friendly controls of the Amana AMH* systems make them easy to operate. Many units come with smart technology that allows homeowners to control their HVAC system remotely via smartphones or tablets. This feature not only enhances convenience but also allows for better management of energy consumption, further promoting efficiency.

Moreover, Amana products are known for their durability and reliability. Backed by a robust warranty, these systems are built with high-quality materials and components, ensuring they can withstand the test of time and varying weather conditions.

In conclusion, the Amana AMH* series represents a blend of energy efficiency, innovative technology, and user-friendly features, making it an excellent choice for homeowners seeking reliable and effective climate control solutions. With a focus on sustainability, comfort, and quiet operation, the AMH* series stands out as a leader in the HVAC market.
