Item Details
Modern Outdoor Linear Gas Fireplace
The Tahoe 450L features a long, linear firebox with a 14-1/2-inch high by 39-inch wide viewing area, providing a wide view of the flames across the fireplace. Its stainless steel construction gives the unit a clean, modern appearance while providing the durability needed for outdoor applications.
The fireplace can be built into an outdoor wall with the 3-inch stainless steel trim visible, or installed as a clean-face design with finishing material brought up to the glass viewing area. This allows the Tahoe to work with a variety of patio, outdoor kitchen, and architectural designs.
Stainless Steel Construction for Outdoor Use
The Tahoe 450L is constructed entirely from stainless steel, making it well suited for outdoor environments. The fireplace also includes a stainless steel cover that protects the firebox when the fireplace is not being used.
A cover kill switch is included as part of the design, adding an additional safety feature when the fireplace is covered.
The Tahoe also includes a 6-inch glass shield positioned above the burner to help protect the flame while maintaining an open view of the fire.
40,500 BTU Linear Gas Burner
The Tahoe 450L uses a stainless steel pan burner with a distinctive criss-cross pattern. With up to 40,500 BTU of output, it provides a substantial flame presentation for outdoor entertaining areas.
The linear burner design spreads the flames across the length of the firebox, creating a wide, contemporary fire display that works particularly well with the Tahoe’s horizontal design.
Natural Gas or Propane
The Sierra Flame Tahoe 450L is available for both Natural Gas and Liquid Propane, giving homeowners and builders flexibility based on the available fuel source at the property.
The current Sierra Flame documentation lists separate Natural Gas and Liquid Propane models, with conversion kits also available.
Decorative Rock & Black Fire Glass
The Tahoe 450L includes a combination of decorative rock media and black reflective fire glass.
The 9-piece decorative rock media set adds a natural element around the burner, while the black reflective fire glass creates a cleaner, more contemporary appearance and helps reflect the flames.
The combination of rock and black fire glass gives you a modern outdoor fireplace design without making the firebox look overly traditional.
Stainless Steel Cover Included
One of the practical features of the Tahoe 450L is its included stainless steel cover. When the fireplace is not in use, the cover can be placed over the unit to help protect the firebox from outdoor conditions.
The cover also incorporates a kill switch, which is designed to shut the fireplace off when the cover is installed.
Electronic Ignition & Remote Control
The Tahoe 450L uses a battery-powered electronic ignition system for convenient operation. A remote control is also included, allowing you to operate the fireplace without reaching into the firebox.
Control Features
- Battery-powered electronic ignition
- Included remote control
- Stainless steel cover with kill switch
- Natural Gas or Liquid Propane fuel options
Flexible Installation Options
The Tahoe 450L can be incorporated into an outdoor project in several ways. It can be built into a wall with the 3-inch stainless steel trim providing a framed appearance, or installed as a clean-face fireplace with finishing material brought directly up to the glass viewing area.
Wood framing is allowed, providing additional flexibility for builders and contractors during installation. Always follow the manufacturer’s installation instructions, required clearances, and local building and gas codes when installing the fireplace.
