Wood stoves are a smart way to heat a Hodgkins home through a long winter, and more homeowners along Joliet Road and the older streets near the rail yards are adding them every year. The single most common mistake we see is a new stove connected to the old, oversized masonry flue that was built for an open fireplace. That mismatch is what turns a safe appliance into a creosote factory.
Why a big flue is the wrong flue for a stove
An open fireplace sends a huge volume of warm air up the chimney, so it needs a large flue. A modern stove burns slowly and efficiently and sends far less exhaust up the stack. Push that small, cool exhaust stream into a large clay-tile flue and it loses heat immediately, slows down, and condenses onto the cold tile walls as creosote. Draft suffers, smoke spills when you open the door, and the buildup that causes chimney fires arrives in a single season.
What correct sizing looks like
Stove manufacturers specify a flue diameter, usually six inches for most residential units. A stainless steel liner of that size, run from the stove collar to the top of the chimney and insulated, keeps the exhaust warm and moving. The result is a stove that lights easily, burns cleanly, and leaves a fraction of the creosote an oversized flue would collect.
Warning signs the liner is wrong or missing
- Smoke rolls out when you open the stove door
- Glass blackens quickly after every burn
- Heavy, shiny creosote in the flue at the annual sweep
- A stove that never seems to reach a hot, clean burn
- Creosote dripping or staining at the flue connection
The safe setup for a Hodgkins stove
Have the chimney inspected before installation, install a properly sized insulated stainless liner, use a listed connector pipe with the right clearances, and burn only seasoned hardwood. Then keep the annual inspection on the calendar, because even a correctly lined stove flue needs sweeping, sometimes more than once a season for heavy users.

Can I vent a wood stove into my existing masonry chimney?
Only through a correctly sized stainless liner. Connecting a stove directly to a large old flue causes poor draft and rapid creosote buildup.
What size liner does a wood stove need?
Most residential stoves call for a six-inch liner, but always follow the manufacturer's specification for your model.
Why should the liner be insulated?
Insulation keeps the exhaust warm all the way up, which improves draft and sharply reduces creosote condensation on the liner walls.
How often should a wood stove chimney be swept?
At least once a year, and heavy users who burn daily through winter often need a mid-season sweep as well.
