Flame Authority Expert Recommendation
Choose the Empire White Mountain Hearth Whiskey River when you want a complete traditional gas-log presentation with a coordinated Contour Burner and the ability to select among several sizes, fuel types, and control systems.
The key decision is the control family. Choose VFDM for straightforward manual operation, VFDR when remote-ready millivolt flexibility matters, or VFDT when integral thermostat control is preferred for an approved vent-free installation.
Before ordering, verify the 18", 24", or 30" size, Natural Gas or Propane configuration, fireplace dimensions, BTU range, control type, vented or vent-free installation, gas pressure, combustion-air requirements, optional control compatibility, glass-door position, damper requirements, and local codes.
