Enviro · Gas Inserts

Shallow on purpose.

The maker’s words — “liner not required,” “traditional log set included.”

I

The shallow one

Under 14″ of minimum depth — built for the shallow zero-clearance fireboxes of the 80s and 90s that most inserts can’t enter.

II

Ready out of the box

“Traditional log set included,” a “steel firebox grate,” the E25 surround included too — and “liner not required” behind the glass unless you want the brick.

III

Two ways to run it

“Standing pilot or IPI versions available” — and the “convection fan is included with the IPI version.” An “up to 50% turn down valve” on both.

Quick answers

The three things everyone asks.

Will it fit my shallow fireplace?

That’s the E25’s whole reason to exist: 27⅞″ × 19¾″ of opening and as little as 13&frac1516;″ of depth. If other inserts have been turned away from your firebox, measure again and bring us the numbers.

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.

Standing pilot or IPI — which one?

The standing-pilot version keeps a small always-on flame and the simplest controls; the IPI version lights electronically and includes the convection fan. We’ll match the version to how you actually use the room.

What it costs
