Yes. The ULT100 is engineered for fully flexible installation. Side panels release in under a minute, allowing you to configure the unit as a traditional front-facing 1-sided fireplace, a 2-sided left or right corner unit, or a stunning 3-sided bay-style centerpiece — all from the same fireplace.
Both options are supported. The ULT100 ships with a 120V plug kit for standard household outlet installation, or it can be directly hardwired to either a 120V or 240V circuit. Hardwiring to 240V unlocks the full 8,530 BTU heat output and is recommended for maximum heating performance.
The integrated Comfort$aver heating system warms spaces up to 1,000 square feet. It delivers 5,118 BTU on 120V or 8,530 BTU when hardwired to 240V. The heater can also be permanently disconnected if you only want to use the flame effects.
Absolutely. The ULT100 features a true flame-only mode, so you can enjoy the realistic Dynamic-Fire flames, Inner Glow logs, and crackling sound effects in spring and summer without producing any heat — making it a year-round design feature, not just a winter appliance.
Each ULT100 ships complete with the firebox, Quick-Connect Inner Glow Rhythmic logs, tumbled glass ember media, gravel, glass chunks, the magnetic wall-mountable remote control with mounting bracket, and the 120V plug kit. Linking brackets for multi-unit installations are sold separately.
The minimum rough framing opening required is 100 3/4" wide x 28" high x 15" deep. The fireplace itself measures 100 9/16"W x 27 1/2"H x 14 1/2"D. We recommend reviewing the official Dimplex installation manual and consulting a licensed electrician and qualified installer before framing.
Yes. The ULT100 includes built-in Wi-Fi and works with the free Dimplex Flame Connect app for iOS and Android, letting you control flame color, brightness, speed, sound, and heat from anywhere in your home.

Yes. The ULT100 is backed by Dimplex's 5-Year Limited Manufacturer's Warranty, which covers 2 years of parts and labor plus an additional 3 years of parts. The unit is UL Listed for both the United States and Canada and is intended for indoor residential use only.
