Wood Burning Best Practices for Customers

Why this matters

Customers love their fireplaces but often don't know how to burn wood safely + efficiently. Poor burning practices create creosote, smoke problems, inefficient heat, and chimney damage. A chimney sweep who teaches customers how to burn well becomes the trusted expert; the customer's system performs better + lasts longer. This reference is the customer-education foundation.

Wood selection

Best woods

These hardwoods burn hot, long, and clean.

Less ideal woods

These work for fireplaces but with limitations.

Never burn

Customer education on this list is critical.

Wood seasoning

Wood must be properly seasoned (dried):

How to recognize seasoned wood:

A moisture meter (consumer tool) verifies seasoning accurately.

Wood storage

Proper storage:

1. Off the ground (pallets, raised platform)
2. Covered top, open sides (rain protection; air circulation)
3. Sunny + dry location
4. Air circulation through the pile
5. Stack with split-side up for water shedding

Storage method affects seasoning quality + speed.

Wood sizing

For typical residential fireplaces:

Match wood size to the fire stage. Large pieces on a small fire = smolder + creosote.

Building a fire

Top-down method (recommended)

The modern best practice:

1. Bottom layer: large splits (3-4 logs)
2. Middle layer: medium splits (perpendicular to bottom)
3. Top layer: small splits + kindling
4. Light the top
5. Fire burns down

Result:

• Cleaner combustion (fire moves into established coal bed)
• Less smoke during startup
• Less creosote
• Easier to maintain

Traditional bottom-up method

For comparison:

1. Kindling + paper at the bottom
2. Light from below
3. Build up with larger wood

This generates more smoke at startup.

Tipi method

Some prefer:

1. Kindling crisscrossed
2. Building outward
3. Lighting

Works but more involved.

Burning a fire properly

For best combustion:

1. Open the damper fully when starting
2. Don't restrict the air during the first 30 minutes
3. Open the air supply on wood stoves
4. Let the fire burn hot initially (30-60 minutes)
5. Reduce the air once the fire is established
6. Add wood when needed but not too much at once

The goal: hot, complete combustion. Smoldering = poor combustion = creosote.

Fire characteristics

A well-managed fire is a hot, bright fire.

When to feed the fire

Don't add wet wood to a marginal fire; it smolders.

Damper management

The damper controls the chimney draft:

For best burning: fully open during startup; partially open during established burn; closed only when fire is completely out + cool.

A common customer mistake: closing the damper "to slow the burn." Result: smolder + creosote.

Wood stoves vs. open fireplaces

Open fireplaces:

• Customer-facing; visual appeal
• Inefficient heat (most heat goes up chimney)
• Significant air loss from the home (drafts)
• Requires significant damper management
• Lower fuel efficiency

Wood stoves:

• More efficient (heat recovery from the box)
• Sealed combustion (more controlled)
• Better burning practices possible
• Modern stoves include catalytic converters
• Higher fuel efficiency

Customer's choice; chimney sweep services both.

Pellet stoves

Different from wood:

• Burns wood pellets (manufactured from compressed sawdust)
• Automated feed (pellet hopper)
• Often electric-powered controls
• More consistent burn quality
• Less creosote (more complete combustion)
• Different service requirements

Some chimney sweeps service these; many specialize in wood-only.

Fireplace inserts

A wood stove built into an existing fireplace:

• Converts open fireplace to insert
• More efficient heating
• Easier to maintain proper burning
• Different chimney requirements (often relined)

Common upgrade for customers wanting efficiency from an existing fireplace.

What customers should avoid

Habits, not fuel. The fuel list is above; these are the practices that damage chimneys and start house fires even when the wood is good.

• Any flammable liquid to start a fire. Gasoline, charcoal starter, lamp oil. The vapor ignites, not the liquid, and it does it all at once. Kindling and patience, every time.
• Burning paper, cardboard, or wrapping paper in quantity. Light flakes lift up the flue while still burning and can set off creosote above. A single sheet to start is fine, a bagful is not.
• Banking a fire down for the night. Choking the air to stretch a burn is the single biggest creosote generator in residential wood burning, and in an open fireplace it also means going to bed with a live fire. Burn hot, let it die, then close up.
• Over-firing a stove. If the pipe or the stove top is glowing, the fire is out of control. It warps steel, damages the liner, and is a chimney fire in progress more often than customers realize.
• Ash handled carelessly. Coals stay live in an ash pile for days. Ash goes into a metal container with a lid, set on concrete or bare ground away from the house and the deck, and it stays there several days before disposal. Never a paper bag, a cardboard box, a plastic bin, a shop vac, or a household vacuum.
• Chimney-cleaning logs sold as a replacement for a sweep. At best they loosen some deposit. They do not remove it, they do not inspect the liner, and they do not find the nest or the cracked tile.
• Running exhaust fans while the fire is lit. A range hood or bath fan on high can pull a fireplace backwards and put combustion gas into the room. Crack a window if the house is tight.
• Closing glass doors on a fire that is not rated for it, or restricting an open fireplace with anything that was not supplied for that firebox.
• Firewood stacked on the hearth or against the stove. It dries, it ignites from radiant heat, and it brings insects indoors. Keep the load to what will burn today and keep it back from the appliance.
• Decorations, stockings, and furnishings inside the clearance zone. The clearance published for the appliance is a fire distance, not a suggestion, and it applies in December too.
• Skipping the annual inspection because the fireplace was barely used. A flue that sat idle collects nests, leaves, and animals. Light season is exactly when those show up as a room full of smoke.
