Keeping a rarely lit Miami fireplace safe for guests and grandchildren

Gas odors and alarms come before everything else

If you smell gas, leave the house now without lighting anything or touching switches, and phone the gas utility or 911 once you are outside. If a CO alarm sounds, get everyone out and call 911 once you are in the yard. Stay out until the responders say the house is safe.

Why occasional use changes the order of the risks

A fireplace that burns most evenings gets watched. One that is lit for a holiday dinner or a visit from the grandchildren spends the rest of the year as furniture. Candles, baskets and dried flowers collect on the hearth. The damper may not have moved in months. Visitors, and especially young children, do not know that the glass or the screen gets hot.

That pattern changes what to check first. The fire itself is rarely the first problem. The hazards are the things left too close to it and the parts nobody has looked at since the last use. Guests who have never been near a working fireplace add a third. This guide follows that order.

Run a first-fire check after idle months

NFPA 211 calls for a yearly inspection whether a fireplace burns every week or twice a season. Gas manufacturers ask for the same. The Heat & Glo owner's manual, for example, says its units should be inspected before use and at least annually by a professional. Book that visit well ahead of the gathering rather than the week of it.

On the day, a few checks take minutes and need no tools.

• Empty the firebox of candles, pine cones, baskets and anything else stored there
• Open the damper fully and leave it open while you light and tend the fire
• Look at the damper plate with a flashlight for twigs, leaves or nest material
• Confirm the screen, glass doors or gas barrier are in place and undamaged
• Test the smoke alarms and CO alarms, and replace weak batteries
• Put back any remote batteries you removed for the idle months

Clear the hearth and mantel before lighting

NFPA's tip sheet says to keep anything that can burn at least three feet away from a fireplace. Measure from the opening and look at the whole zone, not just the floor. Stockings, garland and paper decorations hanging from the mantel sit right above the heat. Take them down for the evening, or move them to a different wall.

Candles need the same care. The Heat & Glo manual tells owners to avoid placing candles and other heat-sensitive objects on the mantel or hearth, because the heat can damage them. CPSC adds that burning candles should never be left unattended. A row of candles in the firebox of a fireplace that is never lit looks calm, but they must come out before any fire goes in.

Hot glass on a gas fireplace and its barrier

The glass front of a gas fireplace gets hotter than most people expect. CPSC says it can reach 500 degrees Fahrenheit or more and cause severe burns in seconds. The Heat & Glo manual warns not to touch the glass until it has cooled, and to teach children never to touch it at all.

CPSC reported that under new industry standards, from January 1, 2015, new gas fireplaces and fireplace heaters that vent outside would come with a protective barrier. The Heat & Glo manual says not to run the fireplace with the barrier removed, and to replace a damaged barrier with the maker's own. For an older unit without one, CPSC notes that safety screens and safety gates are sold for the purpose.

A child holding the remote can also turn the fireplace on. Keep the remote out of reach, and use a wall switch lock or a remote with a child lockout where the unit allows it. If the fireplace sits unused for months, the manual suggests removing the remote batteries and turning off the wall control.

Screens and glass doors on a wood fire

A wood fire needs a sturdy screen to stop sparks from reaching the room, NFPA says. Glass doors are a separate question, because they have to match the fireplace. A factory-built fireplace may be tested with specific door models. One manufacturer's manual names the glass door assemblies its fireplace was tested and listed with, and tells owners to use only parts labeled for that fireplace.

Gas logs in a wood-burning fireplace add another rule. The Real Fyre vented gas log manual says the glass doors must be fully open while the burner runs, and the damper must be fully open too. If you are not sure which doors your fireplace can take, ask before you buy a set.

Baby-proofing and a kid-free zone

Fireplace safety with kids and pets starts with distance and an adult in the room. NFPA recommends keeping children out of a three-foot zone around an open fire. A rug edge or a line of tape can show young visitors where that zone ends. The same zone suits a dog that likes a warm hearth, or a cat that will sit anywhere. Never leave a burning fire alone with children nearby.

Gas fireplace manuals add more steps. The Heat & Glo manual suggests an adjustable safety gate to keep toddlers out of the room, and careful supervision of children in the same room as the fireplace. It also asks owners to consider not using the fireplace when children will be present. For a cold fireplace, a padded guard on a sharp hearth edge can cushion a fall against it. Follow the guard maker's instructions on whether it may stay in place while a fire burns.

Keep matches, lighters and fire tools out of reach as well. A poker set beside the hearth is decor to an adult and a toy to a toddler.

What goes into the fire, and what stays out

EPA's Burn Wise guidance is to burn dry, seasoned wood and to start the fire with newspaper, dry kindling or natural fire starters. Its list of things never to burn includes household trash, cardboard, plastics, and coated, painted or pressure-treated wood. Gift boxes and wrapping from a holiday gathering are household trash. They go out with the trash or the recycling, not into the firebox.

Never use gasoline, kerosene, charcoal lighter fluid or a similar liquid to start or revive a fire. Keep the fire to a size the firebox holds comfortably, and let it burn down while someone is still awake to watch it.

Ashes stay hot long after the evening ends

Ashes that look cold can still hold live embers. EPA says to remove them into a covered metal container and store it outdoors on a nonflammable surface. NFPA's tip sheet asks for cool ashes in the metal container, which then sits a safe distance from the house.

Keep the can away from wood fences, the garage door and anything stacked against the house. Never use a paper bag, a cardboard box or a plastic trash bin for ashes, even the morning after.

Alarms before the guests arrive

NFPA advises testing smoke alarms at least once a month. CPSC recommends CO alarms with batteries or battery backup outside every sleeping area, also tested monthly. Under Florida Statutes section 553.885, a building with a fireplace that went up on or after July 1, 2008 needs a CO alarm near each sleeping room. Older homes benefit from the same layout.

Visiting family may sleep in a den or a spare room near the fireplace. Check that an alarm covers that room before the visit, not after the first fire.

When to call off the fire

Some findings mean the fireplace stays dark until it has been looked at. A cap missing from the chimney, a damper that will not open, cracked gas fireplace glass or a missing barrier all belong on that list. So does smoke that came into the room the last time it was used.

Our free inspection covers the fireplace and chimney before your next occasion, and we explain what we found. When something needs work, the written estimate lists it with upfront pricing so you can decide, and finished work comes with a written record. A chimney inspection suits a wood fireplace. For a gas unit, the visit may lead to gas fireplace repair, and damaged doors or firebox parts to fireplace repair.
