The maker’s words — “Fire-Under-Log Technology” with “Ember Bed Lighting.”
“Fire-Under-Log Technology” starts the flames beneath the stack, so they rise between the logs across the full width — the way a real fire actually burns.
“Ember Bed Lighting” keeps a live coal-bed glow under the fire — and the log set comes traditional or white birch.
The “Run-Quiet Fan System” moves 1,700 ft² of heat without announcing itself — behind a “Limited Lifetime Warranty.”

Quick answers
The Ri30 wants 30½″ × 20″ of opening and a minimum 15″ of depth (the maker’s manual figure; depth varies by surround). Five surround options from Slim to the 46″ Trimmable cover the masonry around it.
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.
Most gas log sets burn above the logs. The Ri30 starts the fire underneath, so flames thread up between the logs across the whole firebox over a lit ember bed — from across the room it reads as a wood fire that never needs feeding.
What it costs
Every wall is different — framing, venting, gas line — so your price is real, not a guess.
