This document describes a series of gas-fired residential single-stage multi-position gas furnaces, available in standard and low NOx models, with input capacities ranging from 40 to 130 MBH. These compact units are designed for induced combustion, reliable hot surface ignition, and feature high heat transfer aluminized tubular heat exchangers. They are factory-shipped for installation in upflow or horizontal applications and can be easily converted for downflow applications, requiring minimal conversion.
These furnaces are designed for residential installation in various locations such as basements, closets, alcoves, attics, recreation rooms, or garages, and are also suitable for commercial applications. Each unit is fully assembled, wired, and tested at the factory to ensure safe, dependable, and economical installation and operation. They are Category I listed, allowing for common venting with other gas appliances as permitted by the National Fuel Gas Code.
The units offer versatile application, supporting upflow, horizontal left or right, or downflow installations with minimal conversion. Their compact design, with an ideal height of 33 inches, makes them easy to install. A blower-off delay feature is included to improve SEER (Seasonal Energy Efficiency Ratio) for cooling. Easy access to controls simplifies power and control wiring connections.
For reliable operation, the furnaces come with built-in, high-level self-diagnostics and fault code displays integrated into the control module. They have a low unit amp requirement, making them suitable for easy replacement applications. A single-wire twinning or staging feature is available, enhancing installation flexibility. All models can be converted to use propane (LP) gas, offering fuel versatility.
The electronic hot surface ignition system contributes to fuel cost savings and increased dependability and reliability. For enhanced safety, a 100% shut-off main gas valve is included. The furnaces are equipped with a 4-speed, direct-drive PSC motor and a 24V, 40 VA control transformer and blower relay, which are supplied for add-on cooling.
The primary heat exchanger is made of hi-tech tubular aluminized steel. The blower capability is timed on and adjustable off, allowing for maximum comfort. A blower door safety switch is incorporated for safe operation. The solid removable bottom panel facilitates easy conversion between different configurations.
Low NOx models are specifically designed to meet stringent code requirements. The units boast an airflow leakage of less than 1% of total airflow under ductblaster conditions, which improves efficiency. The design eliminates knockouts, simplifying installation. Movable duct connector flanges provide flexibility for various applications.
The inducer operates quietly, and its rotatable design allows for easy conversion of venting options. The fully supported blower assembly ensures easy access and removal for maintenance. External air filters are used, offering maximum flexibility in meeting customers' indoor air quality (IAQ) needs.
For venting applications, these furnaces can be installed as a common vent with other gas-fired appliances or connected to a masonry chimney. Quarter-turn knobs are provided for easy door removal, simplifying access for service and maintenance.
Regarding maintenance, the design emphasizes ease of access. The fully supported blower assembly can be easily accessed and removed. The external air filter design allows for flexibility in filter selection and replacement, catering to various IAQ needs. The self-diagnostics with fault code displays assist in troubleshooting and identifying issues quickly, simplifying maintenance and repair. The easy removal of doors with quarter-turn knobs further facilitates access to internal components for servicing.
The manual also provides information on recommended filter sizes and unit clearances to combustibles, which are crucial for safe installation and operation. It specifies that all applications require field-installed air filters, and these must be external to the furnace cabinet. The document also details accessories like LP conversion kits, side and bottom return filter racks, combustible floor base kits, EAC transition kits, masonry chimney kits, high altitude pressure switches, and room thermostats, all designed to enhance the furnace's functionality and adaptability to various installation scenarios and user preferences.
