Majestic Jasper Gas Insert

Majestic Jasper Gas Insert — Homeowner Guide

Quick Overview

The Majestic Jasper is built to upgrade an existing fireplace into a cleaner, easier gas system without rebuilding the structure around it. It gives you direct vent performance, a finished look, and everyday gas convenience while still using the fireplace you already have.

What’s included

This package includes the core components required for a complete installation:

• gas insert unit in natural gas, also available in propane if needed
• selected front
• selected surround
• required direct vent liner kit

The insert itself includes:

• 6 ceramic fiber split logs
• lava rock and glowing embers
• IntelliFire ignition system
• RC300 remote control
• ceramic glass
• battery backup
• power cord assembly
• gas flex connector

The Quick Truth (and quick specs)

• up to 30,000 BTU in natural gas
• up to 28,000 BTU in propane
• actual unit size: 31-1/8 wide x 20-3/4 high x 14-1/2 deep
• visible glass area: 27-1/4 wide x 15-11/16 high
• venting: 3-inch exhaust and 3-inch intake liner system
• vent height: 10 feet minimum, 50 feet maximum
• standard household power for normal operation
• battery backup for outage use

Will it fit my fireplace?

Jasper is designed for an existing solid-fuel masonry fireplace or a UL127 listed factory-built fireplace.

The minimum inside fireplace opening needed for the insert to fit is:

• front width: 31-5/8
• front height: 21
• depth: 15
• rear width: 20-1/8
• rear height: 19-3/16

If your damper area and vent path do not line up cleanly, additional height may be needed to allow proper venting.

Does it cover the opening?

Yes. The surround is the trim that covers the space between the insert and your fireplace opening. It does not affect fit — it determines how clean and finished the final result looks.

• small surround: 40 wide x 27 high
• medium surround: 42 wide x 30 high
• large surround: 44 wide x 32 high

Most installations use the medium surround. Larger surrounds are used when the fireplace opening needs more coverage.

Optional upgrades

• blower (fan) — not included by default, helps push heat into the room
• interior upgrades such as reflective black glass liner, Tavern Brown interior panels, or Cottage Red interior panels
• finish upgrades such as new bronze front and surround options
• propane conversion kit
• wall switch or thermostat controls
• Wi-Fi or remote-related accessories

Clearances (simple)

This is the part that matters in real life: if you want a mantel or a TV above the insert, that needs to be planned before installation.

• deeper mantels need more space above the unit
• TVs above fireplaces can work, but heat management matters
• the front and surround you choose affect the final spacing
• if your goal is a TV-above-fireplace setup, confirm that layout before ordering

What installation typically includes

• preparing and cleaning the existing fireplace
• running direct vent liners through the chimney
• termination cap installation at the top
• gas line connection
• electrical hookup or power routing
• insert placement and leveling
• front and surround installation
• startup, testing, and safety check

Bottom line

If your fireplace meets the minimum opening size, Jasper will fit. From there, the surround and optional upgrades like the blower and design features determine how the fireplace looks and how effectively it heats your space.
