Dimplex IgniteXL Linear Electric Fireplace Size Guide

The Dimplex IgniteXL is a recessed linear electric fireplace available in four widths: 50", 60", 74", and 100". It installs into a standard framed wall opening with no venting, no gas line, and no chimney. All models support both 120V and 240V hardwired electrical connections.

This guide covers the framing dimensions, electrical requirements, and clearance guidelines you need before ordering or beginning installation. For full product details, pricing, and availability, see the Dimplex IgniteXL product page. To compare the IgniteXL against other Dimplex electric fireplace series, see the Dimplex comparison guide.

The IgniteXL supports two installation configurations, determined by the depth of the wall framing:

Partially Recessed — 2×4 Wall (3-1/2" framing depth)

When installed in a standard 2×4 partition wall, the unit sits partially recessed with a portion of the firebox extending beyond the wall face. A trim kit (sold separately, model X-XLFTRIM50 for the 50" unit) is recommended to cover the gap between the fireplace face and the finished wall surface. This configuration is suitable for drywall and tile finishes.

Flush-Mounted — 2×6 Wall (5-1/2" framing depth)

A 2×6 framed wall allows the unit to sit fully flush with the wall surface for a clean, edgeless installation. Trim is optional in this configuration. The unit installs without trim to stone, brick, and other solid finish materials; the included trim is used for drywall and tile surfaces.

Wiring Entry Location

The wiring entry point is located on the right side at the bottom of the firebox. Plan the framing to allow routing of the power cable to this location before the wall is closed.

Serviceable from the Front

All internal components are replaceable from the front of the fireplace while the unit is mounted in the wall. No rear access is required for future servicing.

The IgniteXL supports hardwired connection at 120V or 240V. The voltage configuration affects heat output and amperage draw but does not change the framing or rough opening dimensions. Select the voltage based on circuit availability and desired heat output.

XLF50 — Electrical Specifications

XLF60, XLF74, XLF100 — Electrical Specifications

All four IgniteXL models share identical electrical specifications. The voltage and wattage ratings are the same across the 50", 60", 74", and 100" models. Select the voltage based on circuit availability and desired heat output.

Television and Overhanging Objects

For overhanging temperature-sensitive objects — such as a television, mantel, or artwork — always follow the recommendations provided by that object's manufacturer for installation over a heater. The Dimplex installation manual provides a heat zone chart for the area above the fireplace, describing three zones:

• The zone immediately above the unit (within approximately 10–12 inches height and 1–4 inches depth from the glass) is subject to temperatures exceeding 65°C (149°F).
• A broader surrounding zone is subject to temperatures exceeding 40°C (104°F).
• Areas sufficiently above and away from the unit fall below 40°C (104°F).

No single minimum clearance number is stated in the installation manual. The manufacturer directs installers to the overhang manufacturer's own installation guidelines. Consult a qualified installer if you are unsure whether your planned overhang is within safe temperature range.

Outdoor Installation — Overhang Requirements

The IgniteXL is approved for outdoor installation in areas sheltered by an overhang that protects against direct water ingress. To maintain warranty coverage, the overhang must satisfy the following relationship:

Maximum Height ≤ 3 × Projection Length

• Maximum Height — measured vertically from the bottom of the fireplace to the bottom edge of the overhang
• Projection Length — measured from the exposed face of the fireplace to the parallel edge of the overhang

The installation manual specifies the overhang must be more than 24 inches above the bottom of the fireplace and extend more than 5 inches outward. For example: if the overhang is 9 feet above the bottom of the fireplace, it must extend at least 3 feet outward on all sides.

Overheating Protection

The IgniteXL has a built-in thermal cutoff that automatically shuts the unit off if the heater overheats. To reset: turn the unit off at the main disconnect panel and wait 5 minutes before turning it back on. If the heater requires repeated resets, turn off at the panel and contact Dimplex technical support.
