Kozy Heat Bellingham 44

The Bellingham 44 is sized for about 1,250–2,500 sq ft. The manual rates it at 49,500 Btu/h maximum and 18,500 Btu/h minimum input, the same on natural gas and propane. The brochure lists its EnerGuide (P.4) efficiency at 63.03% on natural gas and 63.50% on propane. Real-world coverage depends on your floor plan, insulation, and climate.

Yes—the burner runs on a battery backup, but the fan and lights don't. Day to day it needs a 120-volt circuit that's always hot, and the control module takes four AA batteries (not included) as backup. On battery power the manual says it operates the burner only, so the fan, top light, and ember-bed light stay off until the power comes back.

It's a direct vent fireplace that uses 5" x 8" co-axial pipe, and an approved reducer can take it down to 4" x 6-5/8". Vertical runs go from 3 ft to 50 ft, and horizontal installs allow up to 25 ft of rise plus 25 ft of horizontal run. The optional Kozy Power Vent handles horizontal terminations, and the manual also approves a chimney conversion that runs 4" aluminum flex pipe through an existing Class A or masonry chimney (it specifies a Class A metal chimney of at least 7" ID).

Yes, but it's built for natural gas, so propane needs the #LCK-BH44-SPB propane conversion kit, sold separately. Kozy Heat's option list shows this as a propane valve step motor kit. Converting before the fireplace is framed in is easier, since a later conversion means removing the control board. Maximum input stays at 49,500 Btu/h on propane.

Yes to both, with planning. Kozy Heat's tests found TV surface temperatures stayed at or below 150°F with a 4-1/4" deep recess built above the fireplace, though the manual leaves TV placement to the homeowner. A vented cavity or optional Komfort Zone Kit cuts heat above the fireplace and allows combustible facing and lower mantel clearances. You can also add up to two heat transfer kits, interior or exterior, to move heat to another area of the home or directly outside.

The minimum rough opening is 57-5/8" wide, 46-1/4" 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 16" above the top finishing edge and a 6" deep mantel at 19-1/2", going 1" higher for each extra inch of depth. Floor protection in front isn't required.

A firebox panel set is a required choice—the manual says refractory or black glass panels are needed to operate the fireplace. Panels come in Chicago brick, herringbone, ledgestone, or black glass, and the log set can be traditional or birch. A fan kit, a full-function remote, a top light, an ember-bed light, and a safety barrier screen are standard. A one-piece black rectangle surround is optional.

The included Proflame 2 remote works as an on/off control and a room thermostat. It gives you six flame heights, six fan speeds, six top-light levels, and a split-flow button that turns the secondary burner on or off. In Smart thermostat mode it lowers the flame on its own as the room nears your set temperature, and a wall-mount transmitter is available.

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