Herringbone and firelight.

A deep bronze face on a dark herringbone room, andirons under the logs — the traditional, done richly.

The herringbone room

A dark “Herringbone” brick liner behind a birch or traditional log set — with andirons, like the fireplaces it remembers.

Ember light

“Adjustable Ember Bed Lighting” under the logs — the coals keep glowing after the flames settle.

Cool to the touch

“Cool Surface System HDK included” and a “Run-Quiet Fan System” — comfort engineering under the classic face.

Quick answers

The three things everyone asks.

Do I need a chimney?

No. The G42 is direct vent — a 5″ exhaust and 8″ intake run out a wall or up through the roof. No masonry, no liner, no sweeping.

Will the TV survive above it?

The G-series carries the “Cool Surface System HDK included” — the front runs cooler by design. Mantel and TV clearances still come from the manual; send a photo and we’ll confirm yours.

What’s the upkeep?

No wood to haul, no ash to sweep. Like any gas fireplace it wants an annual service — that’s our trade, and the crew that installs it does it.

What it costs

Priced to your home — not from a chart.

Every wall is different — framing, venting, gas line — so your price is real, not a guess.
