Lennox Fireplace Doors — Compatible Custom Replacements

Lennox Hearth Products built prefabricated wood-burning and gas fireplaces from the 1980s through 2018 (when the hearth division was acquired by HHT). Many Lennox installations are now reaching the 15-25 year point where factory glass doors need replacement. Custom doors at ExceptionalFire fit all major Lennox models, ship free across the continental US, and outlast the factory units 2-3x.

Lennox prefab series — what we replace

• Hearthstone / Brentwood (wood-burning)
• Montecito / Montebello (premium wood-burning)
• Brookhurst / Cottage / Bella (gas direct-vent)
• Edge ST / Edge GS (modern linear gas)
• Vivid Element (electric/gas combo)
• Most older 1990s-2010s wood-burning Lennox models

Best replacement doors for Lennox

1. Brookfield ZC Deluxe

Designed for prefab fireplaces with louvers. 1-9/16" overlap; ±1/4" tolerance. The default recommendation for most Lennox replacements.

2. Stiletto / Stiletto Cutback

3. Cabot

Slim 5/8" overlap; clean modern look. Best for Lennox premium gas direct-vent units (Cosmo, premium Edge).

Why factory Lennox doors fail

• Aluminum frame warping after 10-15 years of heat cycling
• Painted finish chipping/fading
• Brittle plastic glass-retention components
• Stamped frame air leaks
• Replacement parts often unavailable post-2018 acquisition

Measuring

1. Open factory doors fully
2. Width at top/middle/bottom — use SMALLEST
3. Height at left/center/right — use SMALLEST
4. Note louver positions and front-face depth
5. Photo + measurements via AI Fireplace Expert for fit confirmation

Frequently asked questions

Will custom doors fit my Lennox Hearthstone / Montecito / Edge ST?

Yes — custom-sized to YOUR opening regardless of model. Send a photo + measurements; we confirm fit before production.

Are Lennox factory parts still available?

Limited — many older Lennox parts went out of stock after the 2018 HHT acquisition. Custom replacement doors are often the only practical solution for 15+ year old Lennox units.

Will my Lennox's mesh screen still work?

Yes — Brookfield ZC Deluxe coexists with factory mesh screens.

Does the factory Lennox frame stay in place?

Usually yes — replacement doors mount to the existing factory frame.
