(1)Wire size should be determined in accordance with National Electrical Codes. Extensive wire runs will require larger wire sizes.

(2)Maximum Overcurrent Protection Device: May use Time Delay Fuse or HACR type Circuit Breaker of the same size as noted.

(3)Off Heating - this fan delay timing is adjustable (100 or 150 seconds), 150 seconds as shipped.

(4)See Installation Instructions for appropriate vent diameter, length and number of elbows.

NOTE: This data is provided as a guide, it is important to electrically connect the unit and properly size fuses/circuit breakers and wires in accordance with all national and/or local electrical codes. Use copper wire only.

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

2.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.

3.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.

4.Minimum Circuit Ampacity calculated as: (1.25 x Circulator Blower Amps) + I.D. Blower Amps.

Unit specifications are subject to change without notice. ALWAYS refer to the units serial plate for the most up-to-date general and electrical information.

GCH9 specifications

Goodman Manufacturing has established itself as a reliable name in the HVAC industry, and the GCH9 is a notable example of their commitment to creating energy-efficient and dependable heating solutions. This gas-fired, self-contained horizontal furnace is designed for residential applications, offering high efficiency and durability.

One of the main features of the Goodman GCH9 is its impressive Annual Fuel Utilization Efficiency (AFUE) rating. With a maximum AFUE of up to 92%, homeowners can enjoy reduced energy costs while ensuring their space remains comfortable and warm during the colder months. This high efficiency is achieved through advanced engineering and superior insulation, which minimizes heat loss.

The GCH9 utilizes a dual-stage gas valve and a variable-speed blower motor, contributing to its efficient operation. The dual-stage valve allows the furnace to modulate its output based on the heating demand, which means it can operate at a lower setting on milder days and ramp up when temperatures drop. This not only enhances comfort but also aids in reducing energy consumption. The variable-speed blower motor further optimizes airflow, improving the furnace's overall performance and allowing for quieter operation.

Another key characteristic of the Goodman GCH9 is its durable construction. The heat exchanger is crafted from aluminized steel, ensuring longevity and endurance against corrosion. Additionally, the furnace is equipped with a robust cabinet that provides both insulation and sound dampening, resulting in a quieter operation when compared to other models.

Installation of the Goodman GCH9 is streamlined thanks to its flexible design options. It can be installed in various configurations, making it suitable for diverse home layouts. Moreover, the GCH9 includes a multi-position design that facilitates downward, horizontal, or upflow configurations, allowing contractors to adapt to specific installation needs.

For homeowners seeking peace of mind, the Goodman GCH9 also comes with an excellent warranty. The limited lifetime warranty on the heat exchanger and a 10-year limited parts warranty further underscore Goodman Manufacturing's commitment to quality and customer satisfaction.

In summary, the Goodman GCH9 gas furnace stands out with its high AFUE rating, energy-efficient technologies, durable construction, and versatile installation options, making it a smart choice for modern homeowners looking to enhance their heating systems. With its combination of reliability and efficiency, the GCH9 is a testament to Goodman's dedication to quality and performance in home comfort solutions.
