Freestanding Wood Stove Installation Using an Existing Fireplace & Chimney
Reuse Your Existing Chimney — No Full Flue Kit Needed
If you already have a fireplace opening with a functioning chimney, you don’t need a full flue kit to install your Lava freestanding stove. The stove sits inside the existing opening and uses your existing chimney to carry smoke away. All that’s required is a short stainless steel flue connecting the stove to the chimney cavity — a minimum of 2 metres — which is enough to create sufficient draft and safely extract smoke. This existing-chimney installation saves you the cost of running flue pipe all the way to the top of the chimney.
Aligning the Flue with the Chimney Cavity (45° Offset Kit)
In most installations, the stove’s flue outlet won’t line up exactly with the chimney cavity above it. To bridge this offset, the flue kit typically consists of 2 x 45° bends plus 2 x 1000mm single-wall stainless steel flues, angling the flue across so it connects cleanly into the chimney.
Rear-Exit Flue Option
Prefer a rear flue exit instead of straight up? We also offer a rear-entry flue kit made up of 1 x 90° bend and 2 x 1000mm single-wall stainless steel flues, routing the flue out the back of the stove and up into the chimney cavity.
Heat Loss & Optional 220V Convection Fan
Because warm air becomes trapped in the fireplace cavity around the flue — even when the opening is sealed — this type of installation results in some heat loss up the chimney. To push that heat forward into the room instead, we recommend adding an optional 220V convection fan (+R1750). This directs trapped heat back into your living space for noticeably better efficiency, and requires a 220V power point near the fireplace.
