Kozy Heat Lakefield XL

The Lakefield XL is rated to heat about 1,000–2,000 sq ft, enough to carry an open main floor. The electronic-ignition LXL-22-L burns up to 40,000 BTU/h and down to 22,000 BTU/h on both natural gas and propane. Its EnerGuide (P.4) efficiency is listed at 69%, and the manual approves it for bedrooms.

A screen front is required and sold separately. Choose a black rectangular full, prairie, or arched prairie screen front. The eight-piece log set is part of the stove, and black glass or Canyon Creek brick firebox panels are optional upgrades.

Yes. The electronic-ignition model runs on its backup battery pack, which keeps the burner and its flame modulation working, though the fan and light kit won't run on battery power. Kozy Heat says to put the batteries in only during an outage. The standing-pilot model is described as running with no electricity at all; its manual isn't among the sources here.

The electronic-ignition model comes with a Komfort 8K1 remote with a room thermostat, five flame levels, a 15- to 180-minute shut-off timer, and a child lock. It also runs a fan at three speeds that starts three minutes after the stove lights and keeps running 12 minutes after it shuts off. For the standing-pilot model, a 150 CFM fan kit, on/off and thermostat remotes, wireless wall switches, and wall thermostats are sold as options.

It uses 4″ x 6-5/8″ co-axial direct-vent pipe off the top of the stove, through the roof or a wall. A vertical run can be 36″ to 50 feet. For a wall termination the pipe must rise at least 24″, and the horizontal reach grows with the rise: 24″ of horizontal pipe with a 24″ rise, 8 feet with 36″, 12 feet with 48″, and up to 25 feet with a 25-foot rise, using no more than five 90° elbows. Vertical co-axial flex pipe isn't approved.

Yes, if it's a masonry fireplace: The manual shows the stove sitting inside an existing masonry fireplace, with no hearth or noncombustible floor required in front, 3/4″ mantel trim allowed from 40-1/2″ above the floor, a 6″ mantel from 44″, and 3″ from the masonry opening to a combustible mantel leg or sidewall. It can vent up the old chimney with a 4″ flex liner in a Class A or masonry chimney of at least 7″ inside diameter, or with 3″ x 3″ co-linear liners in at least a 6″ x 8″ masonry or 7″ Class A chimney, using 10 to 50 feet of liner. Have the chimney inspected first.

The Lakefield XL needs 3″ from the top of the stove to a side wall and to the back wall, 1-1/2″ from a top corner to a wall, and 36-1/4″ from its top to the ceiling, with at least 68-1/4″ from floor to ceiling. A horizontal vent pipe needs 2-1/4″ to the ceiling. It can also sit in an alcove, and it has to stand on wood, a noncombustible surface, or a metal or wood panel the full width and depth of the stove.

Yes, but it ships for natural gas, and the conversion kit is sold separately. For the electronic-ignition model, the parts list names the propane conversion kit (LCK-LX22L-D) and a propane valve stepper motor (DEX-SMLP). The manual rates it at the same 40,000 BTU/h maximum and 22,000 BTU/h minimum on propane as on natural gas.

Yes, where local codes don't prohibit it. The manual approves an aftermarket, permanently located manufactured home (marked USA only) or mobile home. At 207 pounds, it needs a level floor that can carry the stove and its venting.
