Your First Fire of the Season: A Safe Start-Up Routine

Chimney Academy · Safety · Updated October 2026

Why the first fire deserves extra attention

A fireplace or wood stove spends most of the year doing nothing. Over those months, things change quietly. Birds and squirrels look for shelter in flues. Damper hardware stiffens or rusts. Rain finds a way past a cracked crown. A stack of kindling sits near the hearth and gets forgotten.

New Jersey fire officials have noted that chimney and fireplace fires tend to cluster at the start of the heating season and are usually preventable with maintenance and cleaning. That is the reason the first fire is worth a routine rather than a casual match.

This guide covers a walk-through for a wood-burning fireplace or stove that has been working normally. It does not diagnose a chimney that has been neglected for years. For that, see using a fireplace again after years unused.

Step 1: Look before you light

Do this with the fireplace cold and a flashlight in hand. You are looking, not repairing.

• Firebox floor and walls. Look for loose brick, missing mortar, or pieces of tile or masonry that were not there last spring. Debris on the hearth can mean something is shedding above. See mortar, brick or tile pieces falling into your fireplace.
• Damper. Open it and close it once. It should move without force. A damper that binds, drops, or will not open all the way is a reason to stop, not to push harder.
• Above the damper. Shine the light up. You are checking for a visible blockage such as nesting material or a heavy pile of debris. If you see any, do not light. Our guide on animal noises and nesting in a chimney explains the next step.
• Surroundings. Move rugs, firewood, newspapers, and furniture back from the opening. State fire safety guidance suggests keeping flammable items at least three feet from the fire and heat source.
• Screen or doors. Make sure the screen is in place and undamaged.

Also check the last service date. If the chimney was not swept and inspected after the last burning season, schedule that before you burn heavily. A chimney that has been used regularly should be inspected at least once a year, and swept when the inspection says it needs it.

Step 2: Check the alarms and the extinguisher

Smoke alarms and carbon monoxide alarms belong on every level of the home and near sleeping areas. Press the test button, and replace any alarm that is more than ten years past its manufacture date. Many people tie this chore to the clock change in the fall.

Know where the fire extinguisher is and read the instructions now, not in an emergency. For more on carbon monoxide specifically, see carbon monoxide and your fireplace or stove.

Step 3: Open, warm, light

Open the damper completely before you strike a match. A damper that is only partly open is a common reason for smoke in the room, and it also slows the flue’s airflow in a way that lets creosote settle.

Then give the flue a head start. A chimney that has been cold for months holds a plug of heavy air, especially one built on an exterior wall. Light a rolled sheet of newspaper held near the open damper for a minute or two so the air starts moving upward. Do this with a small flame and keep your hands, sleeves, and hair clear. Stop if smoke rolls out instead of going up.

Build a small fire first. Use dry kindling and natural fire starters. Never use gasoline, kerosene, or charcoal lighter fluid. Once the flue is pulling, add seasoned splits.

The fuel matters as much as the technique. EPA guidance recommends wood with a moisture content under 20 percent, seasoned for at least six months, and a moisture meter is the reliable way to check. Our guide to dry firewood covers testing and storage.

What a normal first fire looks like

Expect a faint dusty or musty smell for a short while as dust on the firebox burns off. Smoke should rise cleanly. Flames should be lively and the fire should not smolder.

These are signs of a healthy start:

• Smoke goes up and away, and the room stays clear.
• The flames lean gently toward the back of the firebox.
• There is no steady sulfur, tar, or sharp chemical smell.
• The fire burns without loud cracking or popping from inside the chimney.

A damp, sour smell in a warm room is a different matter and is often moisture related. See why does my chimney smell.

Signals to stop and put the fire out

• Smoke spills into the room and does not clear after you confirm the damper is fully open.
• Loud cracking or popping, dense smoke, or an intense hot smell from the chimney. If you suspect a chimney fire, get everyone out and call 911.
• Flakes of black material falling into the firebox.
• A damper, door, or screen that warps, glows, or sticks.
• Anyone in the home develops a headache, dizziness, nausea, or unusual sleepiness while the fire is burning. Get to fresh air and call 911 if you suspect carbon monoxide.

After the fire: ashes and shutdown

Never leave a fire unattended, and make sure it is fully out before you go to bed or leave the house. Let ashes cool. Scoop them into a metal container with a lid and keep it outdoors, away from the house and any wooden surface. State fire officials have warned that ashes can stay hot enough to ignite materials for several days, even when they look cold. Soaking them in a metal bucket of water and letting them sit before disposal adds a margin of safety.

Close the damper after the fireplace has cooled and you are sure nothing is still smoldering. Closing it too early can push smoke and carbon monoxide into the house.

When to call a professional

Call for an inspection if anything in step 1 looked off, if the chimney has not been inspected in more than a year, or if the first fire behaved in a way the list above flags. An inspection confirms what is actually happening; this checklist only tells you when to ask. AM Chimney Sweep offers chimney inspection and chimney cleaning and explains findings and options before any work begins.

This guide cannot tell you whether your particular flue is sound, what is inside it, or whether your appliance is installed correctly. Those questions need a qualified person to look.
