Dimplex Multi-Fire 42" Slim Linear Electric Fireplace

Dimplex Multi-Fire 42" Slim Linear Electric Fireplace

The Dimplex Multi-Fire 42" Slim Linear Electric Fireplace (model PLF4214-XS, Dimplex order number X-PLF4214-XS) is built for walls that will not take a deep firebox. It needs a framed opening only 4" deep — including the drywall — so it goes flush into a standard 2x4 stud wall with no furring out, no bump-out and no structural work. If you cannot frame at all, a wall-mount bracket is in the box.

That slimness does not cost you the fire. Multi-Fire® SL produces large, high-contrast flames with a multi-layered colour effect, and mirror technology behind the glass creates an illusion of depth the physical box does not have.

Key Features

• Multi-Fire® SL Flame Effect
  Large, high-contrast flames with a multi-layered colour effect. Colour settings run independently or in one of seven presets.
• Slim Design
  Flush into a 2x4 wall, or wall-mounted with the included bracket — the only unit in the Dimplex range that gives you both.
• Flush Framing
  The factory-fitted trim lifts off, so finish material can run right to the glass for a frameless look.
• Media Accent Colours
  Preset colour themes, or cycle through the range in custom mode and freeze on the hue you want.
• Mirror Technology
  Creates an illusion of depth behind the flames despite the shallow firebox.
• Ambient Light Sensor
  Adjusts firebox brightness automatically from day to night.
• Built-in Timer
  Shuts the unit off automatically after up to 8 hours.
• Heat Management
  Switch the heater off at the controls for flame-only running, or hard-disconnect it at installation where heat is not wanted.
• Smart Self-Diagnostics
  Built-in diagnostics that make troubleshooting and service simple.

Will It Fit? Rough Opening

A word on that framing width, because Dimplex has two versions of it in circulation. An earlier printing of the installation guide gives 43"; the current printing gives 42 1/2", which is what we have published. 42 1/2" is also the figure that makes sense against the 43 1/4" trim, leaving 3/8" of overlap each side. If your installer is working from a printed manual showing 43", call us before cutting.

Electrical Requirements

Note the 12.5 A draw against a 15 A circuit — this needs its own dedicated circuit, not a shared one. We stock the PLFXSPLUG cord kit if you would rather plug it in than hardwire. Every size in this range draws the same 1,500 W, so the 42" costs no more to run than the 36".

Clearances

That last figure is the one people ask about when planning a TV above the fireplace — 7" is a close measurement, better than most. Check your TV manufacturer's own ambient temperature limit as well.

This is an indoor appliance. Dimplex's guide states it is not to be used outdoors, and it must be installed so water cannot enter.
