Linear gas fireplace
installation.
The linear format — wide horizontal flame, clean face, no log set or ceramic ember bed — is the most requested format on the Eastside right now. It suits the wide, connected rooms in contemporary Bellevue, Kirkland, and Mercer Island homes better than a traditional box fireplace. And it asks more of the installation: recessing depth, direct-vent termination path, surround clearances, and design intent all work differently than a traditional insert or new-build.
Format drives everything downstream
Three linear formats,
three installation scopes.
“Linear fireplace” covers a wide range of formats. The design choice determines the installation scope — venting path, recessing depth, surround clearances, and where in the room the fireplace can live. Format comes first.
01
Wide single-sided linear
The most common linear format. A horizontal firebox with a wide glass face — 42” to 72” and wider — mounted flush or recessed into a feature wall. The flame geometry reads across the room and suits the proportions of a great-room wall or a living room with high ceilings. Heat & Glo’s Crave and Provident series, Napoleon’s Luxuria and Elevation X, and Mendota’s FullView are the most-requested units in this format. Installation is direct-vent through the wall or through a new chase; recessing depth varies by unit.
02
See-through / peninsula linear
A double-sided linear unit — visible from two sides, usually separating a kitchen or dining area from a living zone. The flame is the room divider. Heat & Glo’s Tru-View and Valor’s multi-sided series are the most common in this format. Installation is more complex: both sides of the glass face need clearances addressed, the unit sits within a framed partition wall, and the venting path requires care to keep both viewing angles clean. The design conversation for a see-through starts with the room layout, not the unit catalog.
03
Three-sided bay / cube linear
Three-sided fireplaces — visible on the front face and both side panels — are less common but create a more dramatic sculptural effect. Most applications are in high-ceiling great rooms or as an architectural element in a luxury primary suite. The installation scope is the most complex of the three formats: three-plane clearances, more depth required in the framing cavity, and a venting path that typically requires a dedicated chase. These projects start with the room and work backwards to the unit, not the other way around.
What makes linear installs different
Depth, clearance,
and venting path.
A traditional gas insert or box-format new-build has predictable installation geometry. A linear fireplace has three variables that need to be resolved before the unit can be selected: how deep into the wall the firebox must recess, where the venting terminates, and how the surround handles the transition from the wide glass face to the wall. These are the questions the design walkthrough answers.
- · Recessing depth. Most linear units require a framing cavity of 12”–20” or more. For an existing wall, this means the wall has to have the depth available — or the room accepts some reduction in depth. For a new partition wall being built specifically for the fireplace, the depth is designed in from the start. Unit selection follows from what the wall can accommodate.
- · Direct-vent termination path. Most linear installations use direct-vent through an exterior wall. The unit has to be within reach of an exterior wall that can accommodate the co-axial termination cap — and the cap has to be positioned clear of windows, doors, and HOA-visible sightlines. For interior walls with no exterior access, a new chase is required. We confirm the venting path before the unit is selected.
- · Surround clearances. The wide glass face of a linear unit means the combustible surround — the mantel, the stone face, the drywall return — has to be clear of the glass on all four sides by the manufacturer’s specified clearance. For a wide unit, a small clearance error is visible. We pull the installation manual for every unit and design the surround from the clearance numbers first.
- · City of Bellevue permit. A linear gas fireplace installation requires the same mechanical and gas piping permits as any other gas fireplace project in Bellevue. Permit fees are included in the written estimate. The City inspection includes the framing cavity, the venting assembly, and the surround clearances — we design the installation to pass inspection the first time.
Who we work with
The linear brands
we install.
Unit selection follows the room, not the other way around. We install all major brands — the notes below flag where each brand has specific installation requirements worth knowing before the project starts.
Heat & Glo — Crave, Provident, Tru-View
Heat & Glo’s linear series covers wide single-sided (Crave, Provident) and see-through (Tru-View) formats. The Crave and Provident are among the most-requested linear units in Eastside installations for their flame presentation and clean glass face. Tru-View installs require careful planning of both viewing zones. Heat & Glo units typically have good regional dealer availability, which matters for parts and service.
Napoleon — Luxuria, Elevation X
Napoleon’s Luxuria and Elevation X are wide-format linear units with clean minimal bezels and strong flame output. The Luxuria’s glass width options make it flexible for different wall scales. Napoleon has a strong regional service network on the Eastside.
Mendota — FullView
Mendota’s FullView series is a high-output direct-vent unit with a wide glass face and strong radiant heat performance. The FullView is commonly specified for rooms where heat output matters as much as visual impact — larger great rooms and primary living areas in Bellevue and Mercer Island homes. Mendota has a Midwest-based dealer network; lead times and parts availability are worth confirming at the design conversation.
Valor — G-Series, multi-sided
Valor’s radiant-heat philosophy produces strong BTU output from a compact firebox. The Valor G-Series and multi-sided units are less common in linear applications but are well-suited to rooms where actual heating performance is the primary objective. Valor units are radiant-focused — the heat source is the glass face, not a blower. This suits rooms where the fireplace is the primary heat source for a zone.
