Minimum Clearances to Combustible Materials
| Position | Sides | Rear | Front | Bottom | Flue | Top |
|---|---|---|---|---|---|---|
| Upflow | 0" | 0" | 3" | C | 0" | 1" |
| Horizontal | 6" | 0" | 3" | C | 0" | 1" |
Note: C = If placed on combustible floor, the floor MUST be wood ONLY.
Airflow Data
Detailed airflow data is provided in tables for various models (GMEC960302BNA, GMEC960402BNA, GMEC960603BNA, GMEC960803BNA, GMEC961004CNA, GMEC961205DNA) based on DIP switch settings and temperature rise. This data is crucial for proper system setup and performance tuning.
Note: All furnaces ship as high speed for cooling. Installer must adjust blower speed as needed. For most jobs, about 400 CFM per ton when cooling is desirable. Do not operate above 0.5" w.c. ESP in heating mode. Operating CFM between 0.5" and 0.8" w.c. is tabulated for cooling purposes only.
Wiring Diagram
A comprehensive wiring diagram is included, illustrating the electrical connections for the integrated control module, blower motor, igniter, pressure switches, limit controls, and other components. It also provides diagnostic LED flash codes for troubleshooting.
Accessories
Various accessories are available for the GMEC96 series furnaces, including different vent kits, drain kits, filter racks, and high-altitude conversion kits. Availability is indicated by a checkmark (✓) for each model.
