Glass or logs — your burner.

The maker’s words — “available with glass or log set burners.”

I

The large window

27″ × 16⅝″ of glass on a 32″ opening — the step up to large, with the herringbone, ledgestone or fluted liners behind it.

II

Your burner, your call

“Available with glass or log set burners” — the same firebox runs a traditional log fire or a contemporary glass bed. “Remote or thermostat controls” too.

III

Both pilots offered

“Standing pilot or IPI system with remote” — plus “quick-access valve controls” on the Contemporary and Extruded surround panels.

Quick answers

The three things everyone asks.

Will it fit my fireplace?

The E33 asks for 32″ × 20″ of opening and 18⅛″ to 20½″ of depth. Ten surround choices — Cast Plus to the 46″ Trimmable Filler Panel — close the brick around the new fire.

What happens to my chimney?

No new chimney — your existing one does the work. We run two continuous liners down it (a co-linear direct-vent pair, 3″ each): one brings combustion air in, the other takes exhaust out, and the firebox stays sealed from your room. We sweep and inspect the chimney first, and every gas connection is made by TSSA-registered technicians.

Glass burner or log set?

Logs read traditional — the herringbone liner and a stacked fire. The glass burner reads contemporary — a clean flame line over a glass bed. Same insert, same heat; we keep both burning at the showroom so you can pick by eye.

What it costs
