Fire As Art

It's not enough to call Fireplace Xtrordinair's Xtreme a "fireplace." It just doesn't quite do it justice. The creation is a fire viewing appliance, a new way to display and see what it means today to start a fire in the home.Don't forget care, maintenance and upkeep for older models.

Deadline Newsroom - Tomorrow's fireplace today is fire as art.

Take the Xtreme.

It's not enough to call Fireplace Xtrordinair's Xtreme a "fireplace." It just doesn't quite do it justice. The creation is a fire viewing appliance, a new way to display and see what it means today to start a fire in the home.

But, whatever you call it, the Xtreme is where technology goes when burning wood becomes a threat to the planet.

This summer, the San Francisco Bay Area Air Quality Management District Board adopted the strictest rules yet for fires in the hearth. All new and remodeled fireplaces and inserts, including gas, wood, pellet or other biomass-burning devices must meet Environmental Protection Agency emission guidelines and be labeled as such. The rules also continue the wood burning ban during "Spare the Air" days for older fireplaces as well as limitations on wood burning that produces smoke exceeding 20 percent opacity. Also, unseasoned firewood must be clearly labeled as containing more than 20 percent moisture and it must come with instructions for drying it out.

No problem for the Xtreme. It was named Best In Show at the Hearth Patio and Barbecue Association's annual Vesta Awards in 2007 because it represents where technology goes when function must follow form in the hearth.

A natural gas or propane fired appliance, the Xtreme is designed for higher placement than the conventional floor-level hearth. Install it at counter level, eye level or in a wall above a bed, the Xtreme's cool-to-the touch viewing aperture gets mounted flush with the wall to provide an elongated five-foot-by-two-foot panorama of hushed fire shimmering on a bed of crumbled glass, behind simulated bamboo or driftwood. Forget the grills and louvers. Wall and remote controlled, the 95,000 BTUs of heat generated can be vented to three living areas.

Add raised or flat framing in a hue that blends with the surrounding wall or frame it in geometric panels of stainless steel and you've got a piece of art that's really on fire for around $5,000 -- before installation.

The Xtreme is the extreme for those today converting wood-burning fireplaces to gas units. Such units are often firebox inserts with gas logs and doors, but they aren't very energy efficient unless you run a gas line for an insert that creates a "greener" zone heating source.

But burning gas is hot because the clean-burning fuel and clean-air technology combine to make products that easily comply with air quality rules.

You can also add a wood burning insert or new fireplace to the hearth and continue to use the existing chimney, typically with some modifications to the flue, but only so long as the new work and product is in compliance with air quality rules. Without the new technology or adequate ventilation emissions levels could be illegal. Backdrafts caused by today's tighter homes can allow smoke from wood burning fireplaces to enter the home.

So it's no surprise that the most sought after built-in fireplaces, inserts, or do-overs are gas-fired, sealed combustion fireboxes that vents directly outside. Direct venting bypasses the need for and the upkeep of a hearth-to-roof chimney or flue while also preventing all combustion by-products from entering indoor air space. Gas fireplaces can be fitted with simulated logs (that mimic glowing embers and charred logs), other exotic elements (like crumbled glass or polished rocks) and technology to render the natural blue flame of burning gas a more desirable yellow glow, to simulate the flames of burning wood.

Offering more than just radiated heat, gas fireplace options include thermostats, blowers and warm air venting to circulate heated air at just the right temperature. Along with the gas fireplace in the traditional hearth there are also free-standing urban models, corner units for cottages, dual-sided and surround fireplaces, as well as arty wall-flush units. Many allow adjacent, above or below placement of real art, a window, or a wide screen home movie panel. Gas-fired technology also makes it safe to install a fireplace pretty much anywhere you want, including bathrooms and bedrooms.

And you don't need to take out a home equity loan for the job. For $5,000 to $10,000 you can transform a room with glowing appeal. And, if you need a traditional hearth to give your gas burner the authenticity of a wood burning fireplace you can add masonry mantels and hearths in limestone, quartz and other mineral products that offer the same heat radiating properties of old brick fireplaces.

Bio-mass burners still have their place. The ICC/RSF's Renaissance Rumford 1000 was a triple-crown winner in the 2008 Vesta competition -- best wood burning fireplace, best low-emission wood burning fireplace and Best in Show overall. And Quadra Fire's Mt. Vernon pellet burning insert was the Vesta winner in 2006.

With the rising cost of natural gas, cheaper-fuel bio-mass burners remain in vouge and can burn wood, pellets, shelled corn, wheat and sunflower seeds.

While the special grade of corn to burn doesn't pop, the aroma of popped corn can be an added pleasure.

Q&A On Hearth Care And Upkeep

Q: More and more often today's newly installed or upgraded fireplaces are closed systems -- direct vented, gas powered fireplaces with a sealed combustion firebox. What's to maintain?

A: That's right, but with the new gas inserts you still have to keep an eye out for carbon buildup caused by burning gas in a manner not recommended by the owner's manual. If you have not upgraded to a new closed insert and are still burning wood in an old open fireplace, or a fireplace insert, stove or other appliance installed in the old firebox, you have to regularly clean and maintain the equipment. If you are burning wood (only seasoned hardwoods, like oak, maple, madrone), pellets or other combustibles, you have to clean out the ash once or twice a week and make sure the damper is working properly.

New or old equipment, if you are still using the old chimney and firebox, even with an insert, you have to be on the alert for even minimal seismic activity that, over time, can pull the chimney away from the house. Seasonal wear and tear can also damage mortar joints and the concrete chimney cap that helps keep moisture out. Regular inspections can detect problems.

Q: How often should these items be inspected?

A: With a new direct-vent insert, refer to your owners manual for care and upkeep. Again, for older wood-burning hearths that still use the original chimney, have your chimney and firebox inspected and cleaned after burning an amount of wood that equals a full cord of wood. A full cord of word measures 4 feet high by 4 feet wide by eight feet long and has a volume of 128 cubic feet. Two level loads of wood in a pick up with an 8-foot bed approximates a full cord.

The inspection with a high powered light source or video camera can identify maintenance needs such as cracks, mortar deterioration, seismic damage, soot build up and other hazardous conditions. Professional cleaning helps reduce any fire hazard and helps reveal problem areas. Also have the old firebox and chimney thoroughly inspected and cleaned before installing a new insert designed to use the existing chimney.

Q: Who should do the inspection and maintenance?

A: Follow manufactures' guidelines for new appliances. For older chimney-vented, wood-burning fireplaces, hire a guild-certified chimney sweep. A sweep with a contractor's, mason's or similar license is a plus.

Duct Cleaning Often Unnecessary

Forget duct cleaning as regular maintenance. What the duct? Experts say only clear ducts of vermin infestations; clogging levels of dust or debris and substantial amounts of mold.

Deadline Newsroom - Here's one less thing you have to regularly clean -- ducts.

There's growing evidence duct cleaning may be a solution in search of a problem rather than cure for what ails the air in your home.

Consumer Checkbook (subscribers only) research released this year says the dust you see in your ventilation ducts pretty much stays where it is. It likely won't become airborne unless disturbed -- say by duct cleaning. Under most circumstances duct dust is inert and harmless.

Federal and private health officials back up Checkbook -- an independent operation that rates services much like Consumer Reports rates goods -- and stop short of recommending against duct cleaning, but they also do not endorse the work as routine maintenance.

"Should You Have Your Air Ducts Cleaned?" the latest U.S. Environmental Protection Agency information on the subject says succinctly, "Duct cleaning has never been shown to actually prevent health problems. Neither do studies conclusively demonstrate that particle (e.g. dust) levels in homes increase because of dirty air ducts. This is because much of the dirt in air ducts adheres to duct surfaces and does not necessarily enter the living space."

Likewise, a Canada Mortgage and Housing Corporation report includes before and after duct cleaning test results from 33 homes in Montreal. It found no significant air quality or energy efficiency improvements. In some cases, particle levels increased immediately after a duct cleaning job. In other cases, particle levels went down after the cleaning but returned to previous levels within weeks.

Research also has not scientifically demonstrated the effectiveness of chemical biocides, "sealants" and other duct applications cleaning service provides may offer.

There are no chemical biocides registered by the EPA for use in internally-insulated air duct systems.

The EPA does recommend servicing for fuel burning furnaces, stoves or fireplaces before each heating season to protect against carbon monoxide poisoning. And you should regularly have fireplace and wood burning appliance fire boxes and flues cleared of potentially flammable sooty deposits and creosote, the by-products of incomplete combustion.

The EPA only recommends duct cleaning if:

• Ducts are infested with vermin (including rodents or insects), in which case you may also need a licensed pest control operator.

• Ducts are clogged with excessive amounts of dust and debris and/or particles that are actually released into the home.

• There is substantial visible mold growth inside hard surface (sheet metal) ducts or on other components of your heating and cooling system.

Beware of important considerations about mold detection in heating and cooling systems.

• Many sections of your heating and cooling system may not be accessible for a visible inspection, so ask the service provider to show you any mold he or she says exists.

• A positive determination of mold's existence can be made only by a certified microbiology expert and that may require laboratory analysis for final confirmation.

• If you have insulated air ducts and the insulation gets wet or moldy it cannot be effectively cleaned and should be removed and replaced.

• If moisture is allowed to remain for more than 48 hours or other conditions causing mold growth are not corrected, mold will return.

If you decide to go ahead and hire a duct cleaner, follow these EPA recommendations.

• Consider hiring National Air Duct Cleaners Association (NADCA) members who are locally regulated, licensed or certified. Talk to at least three different service providers, get written estimates and only then decide if you want your ducts cleaned. When the service providers arrive have them show you the contamination that would justify having your ducts cleaned.

• Whenever possible, check duct cleaners' references with other customers and with local or state consumer protection authorities or the Better Business Bureau for complaints.

• Don't hire duct cleaners who make sweeping claims about the health benefits of duct cleaning, who say you need routine duct cleaning or who say they are certified by the EPA or other government agency. The EPA does not establish standards for, certify, endorse or approve duct cleaning companies.

• Do not allow anyone to use chemical biocides or sealants without a thorough understanding of the pros and cons outlined in "Should You Have Your Air Ducts Cleaned?"

• Get a written agreement outlining the total cost and scope of the job before work begins. Don't sign anything you don't understand.

Indoor Air Quality Management At Home

Do you know air "fresheners" can pollute? That some air "cleaners" emit ozone? Or that dust mites prefer wool and feathers to synthetics? Clean Air School is in.

by Broderick Perkins

Deadline Newsroom - You can easily clean up bad indoor air quality at home with just a few lifestyle changes and adjustments in your air quality management.

According to the American Lung Association, here's how.

• The best way to freshen air is to clean up the source of odors and ventilate, such as running bathroom exhaust fans. Run fans that exhaust to the outside, such as those in the kitchen or bath, or open windows and place window fans to the blow air out. Add ventilation when you use household cleaning products indoors.

• From cleansers to pet shampoos, some household cleaners leave behind harmful chemicals or give off gases that can irritate or harm your lungs. Read the small print on labels before purchasing any household chemical, including health and beauty products and air "fresheners". If the product has an Environmental Protection Agency (EPA) number, the product is classified as a pesticide but that doesn't mean it's safe. Labels like "organic" and "natural" do not mean a product is safe for everyone either.

• Don't be so quick to turn off exhaust fans in the bathroom or kitchen. They help remove both moisture and air pollutants. Install a quiet, low-energy model. The air inside your home, where you spend most of your time, can be two to five times more polluted than air outdoors.

• Change the way you clean. Dust mites are everywhere and they trigger allergic reactions from sneezing to asthma attacks. A central vacuum cleaner vented to the outdoors is best, but a vacuum cleaner with a micro filter bag or High Efficiency Particulate Air (HEPA) filter will also help remove allergens. If the yuck factor motivates you,+ consider this -- dust mites feed on skin flakes. Clean up one yech and you get the other.

• Hard surface floors like wood, tile or linoleum are easier to clean than carpeted floors. Real hard wood flooring is a better deal -- when it comes to breathing easy -- than engineered wood products used in flooring which can contain volatile organic compounds (VOCs).

• Damp mopping or using a damp cloth to clean hard surfaces at least once a week is a better approach than "dry dusting" which just stirs up the mites and other particles.

• Relative humidity higher than 50 percent helps not only mold and dust mites to thrive, but creepy cockroaches too.

• If someone in your family has allergies or asthma, it's important to encase their mattress and pillows in dust proof or allergen impermeable covers and replace wool or feather-stuffed bedding materials with synthetic materials. Wool or feather stuffed bedding attracts more dust mites than synthetics.

• All combustion appliances that burn gas, oil or wood emit carbon monoxide and other dangerous gases. Properly installed appliances vent the fumes outside, but you should have a carbon monoxide detector in your home and smoke alarms, installed as close to sleeping areas as possible.

• Paint and use other finishing products with reduced or no VOCs to lower the amount of chemical emissions introduced into the home.

• When possible, swap out washable, reusable heating and air conditioning filters for washable electrostatic filters that are more effective at capturing small particles that can get trapped in your lungs. Wash the filter at least monthly, more frequently for high pollution conditions, say, during building construction or renovation.

• Adding a whole-house air filtration and ventilation system (like the so-called Energy Recovery Ventilator) is like giving your home a set of lungs. The system provides your home -- the hearth -- with a continuous supply of fresh, filtered air.
