OverviewProduct details and key features
Give a suitable existing wood-burning fireplace a gas fire with an illuminated ember bed and a choice of oak or birch logs. This SupremeX 30 offer combines the appliance with a specific black front, surround and liner kit, so the listed package is clearly defined.
Included package
- SUPREMEX-I30 natural-gas insert with oak logs, or SUPREMEX-I30BIR with birch logs, as selected
- FS-MI30-BK black Firescreen front
- MI30-4027-BK black 40 × 27-inch surround
- LINK-DV30B vent kit: two 3-inch flexible liners extending to 30 feet, termination cap and flashing
The appliance includes the RC450 remote, variable-speed fan, ceramic glass and LED ember bed. A propane conversion kit, upgraded interior panels and Wi-Fi module are not included.
What must be planned separately
Installation labor, gas and electrical supply, chimney preparation, sealants, insulation and any site-specific adapters or additional vent components are separate. A qualified installer must confirm that the included surround covers the opening and that this liner/termination configuration fits the chimney. The included kit is not a universal solution for every fireplace.
Fireplace fit
For an approved existing solid-fuel masonry or UL127-listed factory-built fireplace, subject to the exact installation manual. Minimum dimensions shown below apply to the standard surround and do not replace all required clearances. Misaligned exhaust collars may require additional height for vent bends. Horizontal termination is not allowed.

Frequently Asked
Why do I need a fireplace screen if I already have doors?
Glass doors should be open when a wood fire is burning at full intensity (heat buildup can crack tempered glass). A mesh screen stays closed during active fires — it blocks flying embers and sparks while letting heat radiate into the room. Best practice is to use both: the mesh screen during active fires, and the glass doors when the fireplace is cold to prevent drafts.
Mesh screen vs. glass screen — what's the difference?
Mesh screens (curtain or panel style) block sparks and embers while letting heat through — safe to keep closed during active fires. Glass screens (tempered glass panels) provide a sleeker look and full visibility, but typically aren't designed to remain closed during a roaring wood fire — they're often used decoratively on gas fireplaces or non-active masonry openings.
Are mesh screens safe with kids and pets?
Mesh screens are an essential safety barrier — they prevent stray sparks and embers from reaching flooring, furniture, or family members. The mesh itself does get hot during a fire and shouldn't be touched until cool. For households with toddlers or pets, look for our child-safe screen options with weighted bases, secure latches, and tip-resistant frames.
What size screen do I need?
For freestanding screens, pick a screen at least 3" wider on each side than the firebox opening, and at least 1"–2" taller than the opening height — this ensures full spark coverage. For fitted screens (those that mount inside the firebox), measure the opening at three points and use the smallest dimension. We custom-build screens to any size on request.
Do you offer free shipping?
Free freight shipping on all orders within the contiguous US. Standard-size screens ship in 5–10 business days; custom screens are made-to-order in 2–4 weeks. 30-day return window on unused standard-size screens.
