Majestic Ruby Gas Fireplace Insert

Majestic Ruby Gas Fireplace Insert — Homeowner Guide

The Majestic Ruby Gas Fireplace Insert is made to turn an existing wood-burning fireplace into a cleaner, easier, everyday gas fireplace. It is a direct vent insert, so it is built to vent through liners run inside the existing chimney, and it is designed for use in a solid-fuel masonry fireplace or a UL127-listed factory-built fireplace.

What’s Included in This Package

This product is sold as a complete standard insert package.

The Quick Truth

• This is for upgrading an existing fireplace to gas
• You choose the size, the front, and the surround
• The package includes the insert, front, surround, and venting kit

Available size and input ranges:

Will It Fit My Fireplace?

The first question is whether the insert itself fits inside your existing firebox. For a standard surround setup, the minimum firebox opening requirements are:

Ruby 25 minimum firebox opening:

• Rear width: 15 1/8"
• Front width: 26 5/8"
• Front opening height: 17 5/16"
• Rear opening height: 15 1/4"
• Unit opening depth: 15"

Ruby 30 minimum firebox opening:

• Rear width: 20 1/8"
• Front width: 31 5/8"
• Front opening height: 21"
• Rear opening height: 19 3/16"
• Unit opening depth: 15"

Ruby 35 minimum firebox opening:

• Rear width: 25 1/8"
• Front width: 36 5/8"
• Front opening height: 24 1/4"
• Rear opening height: 21 11/16"
• Unit opening depth: 15"

If the exhaust collar on the insert and the fireplace damper do not line up, Majestic says to add 4" to the minimum fireplace height for vent-pipe bends.

Does It Cover the Opening?

Once the insert fits inside the fireplace, the surround is what closes the visible gap and finishes the opening.

Ruby 25 surround sizes:

• Small: 35" x 23"
• Medium: 37" x 26"
• Large: 39" x 28"

Ruby 30 surround sizes:

• Small: 40" x 27"
• Medium: 42" x 30"
• Large: 44" x 32"

Ruby 35 surround sizes:

• Small: 42" x 29"
• Medium: 44" x 32"
• Large: 48" x 32"

For tighter openings or special situations, custom surrounds are available. Majestic also lists medium deep black surrounds for Ruby 30 and Ruby 35.

Choose Your Look

The overall look comes down to the front style and the surround size.

Front styles:

• Inside Fit – the most tucked-in and minimal look
• Clean Screen – a cleaner, more open face
• Arch – a softer, more classic look

Standard surround sizes:

• Small
• Medium
• Large

What Installation Typically Includes

• Insert placement inside the existing fireplace
• Installation of the venting liner system
• Connection to the gas supply
• Front and surround installation
• Final fitment and testing

Some fireplaces may also need additional finish work depending on the firebox shape, chimney path, and surround choice.

Optional Upgrades

If you want to customize the final look further, Majestic also offers additional options depending on model and setup.

• Reflective black glass liner
• Optional interior panels
• Decorative media such as stones or glass
• Driftwood styling on supported configurations
• Wi-Fi module for app control
• Wall switch options
• Custom or on-site surround solutions

Bottom Line

The Majestic Ruby Gas Fireplace Insert is a strong option if you want a real fireplace upgrade with clear sizing, a finished look, and everyday convenience already built in. The standard package keeps the ordering process simple, while still leaving room for finish and design upgrades if you want a more tailored result.
