Outdoor GreatRoom 40-inch See‑Through
An open view through the flame. A finish chosen for your outdoor space.
The decision
A fireplace you finish to belong in the setting.
Start with the Outdoor GreatRoom 40-inch See-Through Ready-to-Finish Fireplace when you want the fireplace to share the stone, masonry or other approved non-combustible finish of your outdoor space. Its two-sided opening keeps a view through the feature, with a linear flame visible from both sides.
Here is the measurement to settle first: 40 inches describes the opening width. The unfinished enclosure is 72 inches wide, 18½ inches deep and 48 inches high. Finishing materials add to that footprint. Plan the whole structure before choosing where the seating, walkway or planting will go.
Why we would look closely
- A see-through opening that can connect two outdoor gathering areas
- A supplied enclosure and burner to build the finished design around
- An internal 20-pound propane-cylinder location on this 40-inch model
What belongs in the complete quote
- The finish, top cap and installation labor
- Approved burner media, purchased separately
- Fuel connection, controls, electrical preparation and access
This guide focuses on the 40-inch electronic-ignition propane configuration. The range also offers other sizes, natural gas and manual-ignition configurations; use the product page to confirm the exact combination you want.
The finished setting
Keep the view. Choose the face of the fireplace.
A see-through fireplace can define an edge between two outdoor spaces while keeping the opening visually connected. Think about what you will see through it from each side: another seating area, the garden, a poolside backdrop or a walkway. We would check both seated viewpoints before deciding which face of the finished wall matters most.
The supplied structure uses galvanized steel framing and fiber-cement backerboard, with a stainless-steel-lined opening. Your finish installer creates the exterior presentation. That makes this a different purchase from choosing a ready-finished concrete fireplace: the final surface, cap, labor and detailing belong in the project budget from the start.
Useful measurements
A 40-inch opening in a six-foot structure.
Use the opening size to judge the flame presentation and the enclosure size to plan the space. The 40-inch electronic model has a 40 × 20-inch opening around its 7 × 37-inch Crystal Fire Plus burner insert. The listed enclosure weight is 220 pounds before your finish is added.
The fireplace supplied
- 72 inches wide × 18½ inches deep × 48 inches high
- 40 × 20-inch viewing opening
- 220-pound listed see-through enclosure
- 80,000 BTU/hr listed input for the electronic model
The finished project
- Additional thickness and weight of the chosen finish
- A suitable supporting surface and access route
- Required clearances, ventilation and service access
- The full gas, control and power arrangement
The 80,000 BTU/hr figure is burner input, not a guaranteed patio-heating area. Choose this fireplace for the two-sided flame and the finished feature you want to build; judge outdoor comfort with the actual layout, wind and conditions in mind. Open the complete 40-inch electronic model specification.
The Hearth Outpost view
Bring the finisher into the decision early.
We like this Outdoor GreatRoom model when the fireplace should look like part of the hardscape. The appeal is being able to carry a chosen material across the feature instead of accepting a fixed exterior finish. The see-through opening then gives the wall a purpose on both sides.
We would start with the finished elevation and a complete installation quote. Ask the finisher to show the vents, access door, top cap and control position on that drawing. Those details can be discreet, but they still need to work after the stone or other approved finish is installed.
If you want a fireplace that arrives with its exterior already finished, a ready-finished model may suit the project better. If a custom exterior is the reason you are shopping, this supplied enclosure-and-burner approach deserves a closer look. Compare the complete finished project rather than the appliance price alone.
Fuel and placement
Keep access in the finished design.
For the 40-inch model, the installation manual shows a 20-pound propane cylinder located inside the base through the access door. For a permanent supply, Outdoor GreatRoom recommends hard piping. Choose the propane or natural-gas configuration that matches the project, then have the installer plan the connection and shut-off access. The DSI burner is fuel-specific and should not be field converted; settle that choice before ordering.
Electronic ignition brings a power decision too. The 40-inch specification recommends an accessible outlet connected to a GFCI circuit. It also lists an optional two-D-cell battery pack, located in a dry, accessible area. Confirm that exact power package before ordering; a finished exterior should leave the service point easy to reach.
This remains an outdoor fireplace. The current manual describes qualifying open-air and partially enclosed outdoor settings; any covered patio needs to meet those conditions, the burner instructions and the applicable clearances. Have your installer confirm the actual location and the support for the enclosure plus its finish.
For built-in framing, use the current manual’s see-through drawing, including the one-inch side and six-inch top clearances to combustible framing. Freestanding finishing has its own drawing and non-combustible zones. Give your installer the current see-through drawings before framing around the enclosure.
The complete order
Quote the finish and fire media separately.
Supplied with the selected fireplace
- Ready-to-finish enclosure and Crystal Fire Plus burner insert
- Stainless-steel-lined see-through opening
- Preinstalled vents and control-panel cutout
- Glass wind guard panels
Choose and quote separately
- Exterior finish, cap and finishing labor
- Approved burner media; the 40-inch electronic spec lists 30 pounds
- External controls, timers or emergency-stop options as needed
- Fuel supply, installation and the selected power arrangement
The electronic specification lists a standard low-voltage switch with the DSI burner. Remote controls and timers are separate choices, so decide how you want to turn on the fire before the control location is concealed by the finish.
Keep the ventilation openings clear. The finish should respect the fireplace’s required airflow and leave the access door and control panel functional. Have any larger surrounding construction designed from the current drawings, rather than simply covering the supplied vents.

Warranty and documents
Five years on the enclosure.
Outdoor GreatRoom provides five-year structural coverage on its ready-to-finish fireplace enclosures. For residential installations, the stainless-steel Crystal Fire Plus burner has a limited lifetime term defined as 10 years, and ignition and electronic components have three-year coverage. That separates the major ownership protections into the structure, burner and controls.
- Ready-to-finish enclosure structure
- 5 years
- Residential stainless-steel burner
- 10 years
- Residential ignition and electronics
- 3 years
The exterior finish is your installer’s work; direct finish-warranty questions to that installer. Coverage begins at purchase and applies to the original owner and original installation in the United States or Canada, with the stated installation, use and maintenance requirements. Glass wind guards have a separate 90-day term. Commercial burner and electronic terms differ.

Speak to an Expert
Good questions
What to settle before the finish goes on.
Is the 40-inch fireplace 40 inches wide overall?
No. The 40-inch designation describes the opening width. The electronic model’s unfinished enclosure is 72 inches wide, 18½ inches deep and 48 inches high; your finish adds to the overall dimensions.
Does it arrive with the stone finish shown?
No. It is a ready-to-finish enclosure-and-burner system. The exterior finish, cap and installation are separate parts of the project. The finished stone photograph shows the 60-inch version as a finishing example.
Can the 40-inch model hide a propane cylinder?
The current installation manual shows an internal 20-pound propane-cylinder location for the 40-inch model. Keep its access door usable and have the full connection and installation checked.
Does electronic ignition require an outlet?
The 40-inch specification recommends an accessible GFCI-connected outlet and also lists an optional two-D-cell battery pack. Confirm the selected power package and maintain dry, practical service access.
Can this be used inside the house?
No. It is an outdoor fireplace. Any partially enclosed or covered outdoor setting must meet the current fireplace and burner instructions, clearances and local requirements.
