What should I never burn in a fireplace or wood stove?
Never burn treated, painted, or pressure-treated lumber, plywood, particleboard, pallets, driftwood, plastic, trash, glossy paper, or anything soaked in an accelerant like gasoline. Each one either releases toxic fumes, corrodes your appliance, or packs your chimney with creosote. Burn only dry, seasoned firewood — that's the whole list. Everything else is a chimney fire or a poisoned room waiting to happen.
The toxic list — and what it does
Treated and painted wood is the big one: pressure-treated lumber can release arsenic and chromium, and old paint can carry lead — straight into your living room and into the ash you later handle. Plywood, particleboard, and OSB give off formaldehyde from the glues that bind them. Plastics and household trash release dioxins and hydrochloric acid. Driftwood is loaded with salt that corrodes steel and cast iron from the inside. None of these are fussy preferences — they're the difference between a safe fire and a hazardous one.
The sneaky ones people don't think about
Plenty of trouble comes from things that seem harmless. A whole Christmas tree flares like a torch and can ignite creosote in seconds. Cardboard, wrapping paper, and glossy magazines throw floating embers up the flue and out onto the roof. Wet or green wood smolders and glazes the chimney. And never, ever use gasoline, lighter fluid, or any accelerant to get a fire going — that's how people end up with a fireball out the front of the firebox.
What to burn instead
Dry, seasoned hardwood under twenty percent moisture is what your fireplace or stove was built for. Manufactured logs and compressed wood bricks are fine within your appliance's rules. Beyond that, the best insurance is an annual inspection — creosote from a season of bad fuel is exactly what starts chimney fires here in the mountains. Not sure what's safe in your unit?
