Kozy Heat Bellingham 38

The Bellingham 38 is sized for about 1,100–2,200 sq ft. The manual rates it at 43,500 Btu/h maximum input on either natural gas or propane, and it turns down to 17,000 Btu/h on natural gas (16,500 Btu/h on propane). The brochure lists its EnerGuide (P.4) efficiency at 67.43% on natural gas and 66.65% on propane. How much space it actually warms depends on your floor plan, insulation, and climate.

Yes—the burner keeps running on a battery backup, but the fan and lights don't. The fireplace normally needs a 120-volt circuit that's always hot, and the control module holds four AA batteries (not included) for outages. On battery power the manual says the backup operates the burner only, so the fan, the top light, and the ember-bed light stay off until power returns.

It's a direct vent fireplace built for 5" x 8" co-axial pipe, and an approved reducer can step it down to 4" x 6-5/8". Vertical runs go from 3 ft up to 50 ft, and horizontal installs allow up to 25 ft of rise plus 25 ft of horizontal run. The manual also approves the optional Kozy Power Vent (horizontal terminations only) and two ways to use an existing chimney: 4" aluminum flex in a Class A or masonry chimney of at least 7" ID, or 3" x 3" co-linear flex in a masonry chimney of at least 6" x 8" ID or a 7" ID Class A chimney.

Yes, but it ships set up for natural gas, so propane takes the #LCK-BH38-SPB propane conversion kit, which is sold separately. Kozy Heat's option list shows this as a propane valve step motor kit. It's easier to convert before the fireplace is framed in, because converting afterward means pulling the control board. Maximum input is the same 43,500 Btu/h on propane.

Yes, with the right wall design. In Kozy Heat's tests, TV surface temperatures didn't exceed 150°F when a 4-1/4" deep recess was built above the fireplace, though the manual leaves TV placement as the homeowner's responsibility. For more heat reduction, the optional vented cavity or Komfort Zone Kit setups allow combustible facing above the fireplace, cooler TV placement, and lower mantel clearances.

The minimum rough opening is 51-5/8" wide, 43-1/4" high, and 22" deep, inside an enclosure at least 88" tall. Clearance to combustibles is 0" at the stand-offs, 2" at the corners, and 36" in front. In a standard install, 3/4" mantel trim can start 12" above the top finishing edge and a 6" deep mantel at 15-1/2", rising 1" for each extra inch of depth. Floor protection in front isn't required, and the manual approves it for outdoor covered installs operated between 40°F and 110°F.

You must choose a firebox panel set—the manual says refractory or black glass panels are required to operate the fireplace. The panel choices are Chicago brick, herringbone, ledgestone, or black glass, with traditional or birch logs. A fan kit, a full-function remote, a top light, an ember-bed light, and a safety barrier screen come standard. A one-piece black rectangle surround is optional.

The included Proflame 2 remote turns the fireplace on and off and can act as a room thermostat. It offers six flame heights, six fan speeds, six top-light levels, and a split-flow setting that switches the secondary burner on or off. Its Smart thermostat mode lowers the flame automatically as the room reaches your set temperature, and a wall-mount transmitter is available as an option.

Yes to both, within limits. The manual says the fireplace may be installed in a bedroom. It also allows installation in an aftermarket, permanently located manufactured home (USA only) or mobile home where local codes don't prohibit it; the manual doesn't call for a separate mobile-home kit, so confirm local requirements with your installer.
