Fixing a New Brunswick Fireplace That Smokes Back
How to diagnose a New Brunswick fireplace that keeps smoking into the room.
By design, a fireplace pulls smoke up and out the chimney. If smoke comes into the room in your New Brunswick home, the draft is compromised. There are a few common causes, some quick to fix and some pointing to chimney work.
Rule out the easy causes first
Begin with the obvious causes before anything else. Make sure the damper is fully open, because a partly closed damper is the top culprit. Consider the wood and the cold flue: damp wood burns too cool, and a cold column of air needs priming.
Wet wood and a cold, dense column of flue air are common, fixable draft killers. First eliminate the quick, common reasons. A partially open damper is the most common smoke-back cause, so check it first.
A partially open damper is the most common smoke-back cause, so check it first. Season the wood and warm the flue: both fix a fireplace that smokes on startup. Before worrying, rule out the easy explanations.
- 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
The house-pressure problem
The tightness of modern homes can stop a fireplace from drawing. A fire needs makeup air, and a tight New Brunswick home can be at negative pressure instead. With exhaust fans or an HVAC running, the path of least resistance for makeup air becomes your chimney — so it draws down, and the smoke comes with it. Cracking a window an inch is a simple test.
With exhaust appliances running, the chimney draws down for makeup air; opening a window an inch is the simple test. Newer homes are sealed tight, and that creates a brand-new draft problem. A fire needs makeup air, and a tight New Brunswick home can be at negative pressure instead.
A fire needs makeup air, and a tight New Brunswick home can be at negative pressure instead. 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.
When it is the chimney itself
When the simple checks pass but smoke continues, suspect the chimney. A blocked flue, a flue too short to develop draft, a mis-sized flue, or no cap can all reverse the smoke. A smoke chamber left unparged disrupts the airflow the fireplace needs to draw.
A smoke chamber that was never smoothed can interfere with the rising draft. If basics are fine and it still smokes, the chimney is the problem. A blocked, too-short, or wrongly sized flue, or a missing cap allowing downdrafts, are the common chimney causes.
Common chimney faults are a blocked flue, a flue too short to draw, a wrongly sized flue, or a missing cap that lets wind drive smoke down. A smoke chamber left rough and unsmoothed interferes with the draft that lifts the smoke. When the basics are covered and it still smokes, the chimney is the cause.
A local cause worth knowing
A pair of issues comes up repeatedly on older New Brunswick stacks. First, cold-side exterior chimneys run cold and smoke back before they warm. Second, older flues are commonly oversized or rough inside, hurting draft in fixable ways.
