The maker’s words — the “ultra high definition log set” at the large size.
The “ultra high definition log set” across a 26⅜″ window over classic red brick — at 74.11% P.4 efficiency and 35,000 BTU.
“Adjustable ember bed lighting” with “glass or ceramic embers” — the coal-bed glow dialled from the same remote as the flame.
“Advanced BluIQ technology” on the “SIT Valve 885,” the “Run-Quiet Fan System,” and a “Limited Lifetime Warranty” behind all of it.

Quick answers
Same 32″ × 20″ opening as the E33, a touch shallower at 17⅞″ minimum depth. Nine surrounds from Slim to Cast Plus O/S finish the face.
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.
The EX35 is the finished article: UHD logs, ember lighting, BluIQ remote, 1,900 ft². The E33 is the flexible one: glass or log burners, standing pilot offered. Same hole in the wall — different personalities behind the glass.
What it costs
Every wall is different — framing, venting, gas line — so your price is real, not a guess.
