GMVC8
ComfortNet™-Compatible
Two-Stage, Variable-Speed
Gas Furnace
80% AFUE
Heating Input: 70,000–115,000 BTU/h
Standard Features
• Aluminized steel, dual-diameter tubular heat exchanger
• Two-stage gas valve operates on two-stage or single-stage thermostats
• ComfortNet™ Communications System compatible
• Efficient and quiet, variable-speed ECM circulator motor gently ramps up or down according to heating or cooling demand

Minimum Circuit Ampacity = (1.25 x Circulator Blower Amps) + ID Blower amps. Wire size should be determined in
accordance with National Electrical Codes. Extensive wire runs will require larger wire sizes.

Maximum Overcurrent Protection Device refers to maximum recommended fuse or circuit breaker size. May use fuses
or HACR-type circuit breakers of the same size as noted.

Notes
• All furnaces are manufactured for use on 115 VAC, 60 Hz, single-phase electrical supply.
• Gas Service Connection ½” FPT
• Important: Size fuses and wires properly and make electrical connections in accordance with the National Electrical
Code and/or all
existing local codes.

During Auto-Comfort mode, the furnace ramps up to 50% of the demand for half a minute. It then ramps to 85% of the full
cooling demand airflow and operates there for approximately 7½ minutes. The motor then steps up to the full demand airflow.
This mode spends a half minute at 50% airflow OFF delay.

Notes
• These charts are for furnaces installed at 0’ - 2,000’. At higher altitudes, a properly de-rated unit will have the same temperature rise at a particular
CFM, while the ESP at that CFM will be lower.
• THE INSTALLATION IS TO BE ADJUSTED TO OBTAIN A TEMPERATURE RISE WITHIN THE RANGE LISTED ON THE FURNACE NAMEPLATE.
• Propane gas installations will have a high-stage rise approximately 4° lower than shown in the tables.

Notes
• These charts are for furnaces installed at 0’ - 4,500’. At higher altitudes, a properly de-rated unit will have the same temperature rise
at a particular CFM, while the ESP at that CFM will be lower.
• The installation must be adjusted to obtain a temperature rise
within the range listed on the furnace nameplate.
• Do not operate above .5” w.c. ESP in heating mode.
• Propane gas installations will have a high-stage rise approximately
4° lower than shown in the tables.
