Dimplex Ignite Ultra 100" Built-In Linear Electric Fireplace
Description
Size Options: 50" | 60" | 74" | 88" | 100"
Overview
Eight and a half feet of fire, with no gas line and no venting
At 100-9/16" wide, the Ignite Ultra 100" is the longest fireplace in the series — scaled for a great room, a lobby or a double-height feature wall, with no gas line, no flue and no venting. Rhythmic inner-glow logs pulse in time with the flames and ember bed, crackling sound options add what most electric fireplaces leave out, and the Quick-Connect logs lift out and rearrange without tools. A mirrored glass backer deepens the flame, with 9 flame color themes, 3 ember bed themes, 4 flame speeds and adjustable brightness.
At 14-1/2" deep it needs a framed chase or bump-out about 15" deep, not a standard stud wall, and the 16-15/16" viewing height gives it more presence than a typical linear slot. Install it fully recessed front-facing, as a left- or right-corner unit, or bay-style — or link units with the optional modular linking kit for one continuous run of fire.
Worth planning for: heat output is the same across every Ultra size — up to 1,000 sq ft — so in a room scaled for a 100" fireplace, treat it as ambiance with supplemental warmth rather than a primary heat source.
What's included: the firebox, Rhythmic inner-glow logs, tumbled glass media, multi-function remote with wall bracket, and a 120V plug kit. Not included: the electrical circuit — a licensed electrician hardwires it, or fits the included plug kit to a dedicated 120V outlet. Comparing ranges? See Ignite XL vs Evolve vs Ultra.

About the Brand
Dimplex
Dimplex has been engineering electric fireplaces for more than 30 years and is one of the most recognized names in the category. Its IgniteXL, XL Bold, Evolve, Ultra, and Aspire lines cover everything from 50" to 100" linear built-ins to multi-sided corner units, while Revillusion brings a traditional firebox with a reflective flame panel and flames that appear to rise from within the logs. No gas line, no venting, no chimney — and heat runs independently of the flame, so the fire stays on year-round. As an authorized Dimplex dealer, Lumiflares ships every unit new from Glen Dimplex Americas with free shipping and the full factory warranty.
