Who It's For
An open wood fireplace is messy and drafty, and it rarely gets lit. You want real gas heat from the opening you already have. The Jøtul GI 635 Newcastle is for that fireplace. Leave it as it is and it keeps sending heat up the chimney.
What Makes It Special
The GI 635 Newcastle is a blend of modern cast iron and traditional charm that turns your hearth into the centerpiece of the home.
Electronic ignition, the dual ceramic JøtulBurner III, the Proflame 2 remote with flame control, a blower, and top-firing accent lights come standard. A battery back-up permits continued use in a power failure.
Like every Jøtul gas stove and fireplace, it comes with an approved fire safety screen.
Possible Downsides
- An overlay is a required choice. Pick the cast iron, rectangle steel, or arched steel overlay.
If you want Jøtul gas heat in your existing fireplace, the Jøtul GI 635 Newcastle is the right decision. The fireplace becomes the warmest spot in the house again.
Choose a cast iron or rectangle or arched steel overlay in bronze, Jøtul iron, or matte black, a backer frame, traditional logs or beach fire, and one of four interior panel kits.

Can you get an instant online estimate for the Jøtul GI 635 New Harbor?
Yes—right on this page. Configure the Jøtul GI 635 New Harbor and get a free, no-obligation instant estimate covering the unit as configured, a fitting vent kit, and professional installation labor. No phone call required.
What's included in the online estimate?
The unit with the options you selected, a real vent kit matched to your venting, and the installation labor for a typical setup. Your free one-to-two-hour in-home visit confirms every detail before anything is ordered.
Who pulls the permit?
We do, on every job, in every jurisdiction we serve—and we meet the inspector. It's built into the process, not an upsell.
Can you see the Jøtul GI 635 New Harbor in a photo of your own room?
Yes. The Visualizer tab on this page renders the Jøtul GI 635 New Harbor into a straight-on photo of your wall, scaled to the room, so you see it in your space before you price a thing. Phone photos are fine. It's a faithful preview, not an architectural drawing; sizing, venting, and trim get confirmed at the free in-home visit.
Is the online estimate real, or a rough guess?
Real, and honest about what it is: a price for the Jøtul GI 635 New Harbor as configured, a fitting vent kit, and professional installation labor, built from real Seattle installs. It is not binding. The free one-to-two-hour in-home visit checks your actual house before the price is final, and nothing is ordered until then.
Do you install and service the Jøtul GI 635 New Harbor yourselves?
Yes, both. Our own in-house installers set the Jøtul GI 635 New Harbor, run the venting and the gas, pull the permit, and light the first fire before leaving. Afterward the service desk looks after every unit that came from Sutter, with factory-trained technicians and a real date when you call.
