Z42 Zero Clearance Fireplace Wood Fireplace



The Z42 consists of applied modern technology and design to create a zero clearance fireplace to heat your home safely and efficiently. It is a wood-burning fireplace activated by lighting fuel and tinder inside a closed off area.


Like its gas-burning counterparts, we have designed the Z42 to operate at the highest level of efficiency. This fireplace unit has a 49,133 BTUs BTU/hr input rate. A 73% efficiency rating, it also burns efficiently enough to heat your home as quickly as a gas fireplace. While it cannot be connected to your thermostat, a wood stove will burn at a temperature hot enough to spread heat throughout your space.


As a zero clearance model, the Z42 can be safely lit in a closed space with a fire kit, tinder, and up to twenty-two inch long logs for fuel.
