Description
The Kozy Heat Bayport 41 occupies a unique position in the Kozy Heat lineup — it’s the retrofit-friendly premium gas fireplace. With an unusually shallow 17-inch unit depth (the shallowest in the entire Kozy Heat wall-mounted catalog), it fits in standard 2×6 wall construction and in many existing masonry fireplace openings without the deep wall buildouts or chases that deeper architectural fireplaces require. Pair that with 78% efficiency (top tier in the Kozy Heat catalog), a modulating burner with the lowest 15,000 BTU minimum of any wall-mounted Kozy Heat fireplace, dual media configurations (traditional log set OR contemporary glass media), and rear-or-top venting flexibility — and the Bayport 41 is the right answer for installations where deeper architectural fireplaces simply can’t go.
The Shallow-Depth Premium Fireplace
Most premium architectural gas fireplaces require a deep framing recess (22 to 29 inches) — and that ends up being the dealbreaker for many retrofit installations. The Bayport 41’s 17-inch unit depth and 17-1/2 inch framing depth fit in standard 2×6 stud wall construction and in many existing wood-burning fireplace openings without requiring major framing buildouts, chases, or wall furring. For homeowners who want a premium Kozy Heat fireplace but don’t have the wall depth to accommodate a Bellingham, Callaway, or larger architectural unit, the Bayport 41 is the only option that doesn’t compromise on build quality or efficiency.
The depth comparison tells the story clearly:
| Kozy Heat Model | Framing Depth Required | Fits in 2×6 Wall? |
|---|---|---|
| Bayport 41 (this product) | 17-1/2 in. | Yes (with minimal furring) |
| Callaway 40 | ~22 in. | No — requires buildout |
| Callaway 50 | ~22 in. | No — requires buildout |
| Bellingham 38 | ~22 in. | No — requires buildout |
| Bellingham 44 | ~22+ in. | No — requires buildout |
| Bellingham 52 | 28-3/4 in. | No — requires substantial buildout |
This matters in three common retrofit scenarios:
- Replacing a wood-burning fireplace — many existing masonry fireplace openings are 16 to 20 inches deep. The Bayport 41’s 17-1/2″ framing depth fits in many existing openings without rebuilding the masonry recess.
- Adding a fireplace to an existing wall — 2×6 stud walls (5-1/2″ stud depth + drywall + sheathing) accommodate the Bayport 41 with minimal furring. Deeper fireplaces require building out the entire wall, eating into room square footage and requiring substantial framing work.
- Townhomes, condos, and tight floor plans — wall depth is often constrained. The Bayport 41 doesn’t force you to lose interior space to accommodate the fireplace recess.
