Product Overview

Merit ML297VK Series

Two-Stage, 97% Variable-Speed Gas Furnace that Heats the Home Evenly and Efficiently

Integrated – The Merit® ML297VK Gas Furnace is designed to deliver high-efficiency heating while incorporating an integrated refrigerant detection system for 2025 refrigerant compliance.

At every turn, the ML297VK gas furnace is designed to be the most energy-efficient furnace in its class. A variable-speed fan keeps temperature swings to a bare minimum. Two-stage heating saves gas by adjusting the flame size based on demand.

  • Low NOX - Approved by the California Energy Commission and meets California Nitrogen Oxides Standard (NOx) limits of 40 ng/J
  • Energy-Efficient Design - With a 97% efficiency rating, the ML297VK gas furnace uses 2/3 less energy than competitive single-speed units so you pay for perfectly heated air, not wasted energy.
