What Causes a Danbury Fireplace to Smoke Back
The checklist for a Danbury fireplace that pushes smoke inside.
A fireplace should take the smoke up the chimney without a trace in the room. If smoke enters the Danbury room, something is interfering with the draft. Causes range from a quick adjustment to a real chimney problem.
The five-minute checks
Start by eliminating the simple, common culprits. Check the damper — a partly closed damper is the most common cause of smoke-back, period. Is the wood dry and the flue primed? Wet wood and a cold flue both cause smoke-back.
Is the wood dry, and is the flue cold? Unseasoned wood drafts weakly, and a cold flue should be primed first. Begin with the obvious causes before anything else. Check that the damper is wide open; a partial damper is the leading cause.
Make sure the damper is fully open, because a partly closed damper is the top culprit. Is the wood dry and the flue primed? Wet wood and a cold flue both cause smoke-back. First, check the easy things before blaming the chimney.
- Damper not fully open
- Unseasoned or wet wood burning too cool
- A cold flue that needs priming before the main fire
- Too large a fire for the firebox
- A closed-up house with no makeup air for the fire to draw
Why modern homes smoke back
The tightness of modern homes can stop a fireplace from drawing. A fire needs makeup air, and a tight Danbury home frequently runs at negative pressure. Fans, dryers, and HVAC can turn the flue into the makeup-air path, reversing draft; a cracked window tests the theory.
Exhaust and HVAC can make the flue draw downward for makeup air, and a cracked window tests it. Modern homes are tighter than old ones, and that creates a draft problem fireplaces never used to have. A fireplace draws makeup air to replace its exhaust, which a negative-pressure Danbury home cannot supply.
A fireplace needs makeup air — air to replace what it sends up the chimney — and a tight Danbury home can sit at negative pressure. With exhaust running, the chimney is the path of least resistance and draws down — opening a window an inch is the test. Modern airtight homes can starve a fireplace of the air it needs.
The chimney defects that smoke a room
If you have ruled out the simple stuff and it still smokes, look to the chimney. Chimney-side causes include blockage by creosote or a nest, a short flue, a mis-sized flue, or no cap to stop downdrafts. An unparged smoke chamber disrupts the airflow that is supposed to draw smoke up.
An unparged smoke chamber disrupts the airflow that is supposed to draw smoke up. If you have ruled out the simple stuff and it still smokes, look to the chimney. The chimney causes are blockage, a short flue, a flue sized wrong, or a missing cap that admits downdrafts.
Blockage, a too-short flue, an improperly sized flue, or a missing cap each cause smoke-back. A rough, unparged smoke chamber interferes with the draft carrying smoke upward. Once the easy causes are out and it still smokes, the chimney itself is to blame.
The Danbury exterior-chimney issue
Two draft issues are common on older Danbury chimneys. First, exterior stacks run cold, and a cold flue is much more prone to smoking on startup. Second, older flues are frequently oversized or have rough smoke chambers, both of which we can fix.
