Kozy Heat Callaway 50

It's rated to warm about 900–1,800 sq ft. The burner runs up to 35,500 BTU/h on natural gas (35,000 on propane) and turns down to 18,500 BTU/h (18,000 on propane) for a lower, quieter fire. Kozy Heat lists its EnerGuide P.4 efficiency at 73.49% on natural gas and 72.74% on propane. Real results depend on your floor plan, insulation, and climate.

It's a direct vent fireplace built for 5-inch by 8-inch co-axial pipe, and it can be reduced to 4-inch by 6-5/8-inch pipe with an approved reducer. It can run straight up to as much as 50 feet, or out a wall with up to 20 feet of horizontal run when it first rises 24 inches. The optional Kozy Power Vent (#KPV) is a fan-powered system for horizontal terminations only. It can also be adapted into a sound existing chimney using a 4-inch flex liner (minimum 7-inch ID Class A or masonry chimney) or 3-inch co-linear liners (minimum 6 x 8-inch ID masonry or 7-inch ID Class A).

Yes, but plan the wall for it: The manual's TV guidance centers on a vented cavity or a Komfort Zone Kit, which let a 6-inch-deep mantel sit right at the top finishing edge and allow combustible wall finish up to 1 inch thick. In Kozy Heat's tests with either option, surface temperatures stayed at or below 150°F in a 4-1/4-inch-deep recess above the fireplace, and both need an enclosure at least 76 inches tall. Without them, a 6-inch mantel has to sit 21-1/2 inches above the top finishing edge, and the manual leaves the final TV location to the homeowner.

Yes, the burner will. It uses electronic ignition that normally runs on 120-volt power, and it has a backup pack that takes four AA batteries (not included) to keep the burner working when the power is out. The optional fan and other powered features don't run on battery backup, so you get the fire without the blower until the power comes back.

Yes, but it ships set up for natural gas and needs Kozy Heat's propane conversion kit (#LCK-CW50-SPB), installed by a qualified installer. The manual says it's easier to convert before the fireplace is framed in, since converting later means removing the control board. The order options also list a propane valve step motor.

The safety barrier screen, top light kit, remote control, and the steel framing it needs are included. Burner media is a required separate purchase: reflective midnight or reflective copper crushed glass, or lava rock. Logs, accent kits, firebox panels, perimeter media, surrounds, and the fan kit are all optional.

A fan kit is optional, not included; it's a pair of 75 CFM fans with six speeds on the remote. For moving heat elsewhere, the Callaway 50 can take a Komfort Zone Kit, which sends heat out through plenums, or up to two heat transfer kits that duct heat to another interior space or directly outside. The fans have a five-minute start delay in thermostat mode so the firebox can warm up first.

Yes, where local codes allow it. The manual approves it for an aftermarket, permanently located manufactured home (USA only) or a mobile home. It doesn't call for a separate mobile-home kit, so the standard installation rules apply, including a level floor strong enough to carry the fireplace and venting.

Plan on a rough opening 64-1/2 inches wide, 44-1/2 inches tall, and 22 inches deep (26 inches deep with Metal-Fab pipe), with the included steel framing. A standard install needs at least 72 inches from the base of the fireplace to the ceiling and 3 inches from the side finishing edge to an adjacent wall. It's approved for bedrooms, and it can go in a covered outdoor space with the outdoor kit, sold separately, for use from 40°F to 110°F.
