Frequently Asked Questions

Gas Log Set Buying Guide


Gas log sets bring the enjoyment of “having a fire” at home without the effort and cleanup associated with a natural wood fire. Gas log sets have detailed log arrangements that mimic the look and feel of real wood logs paired with dancing yellow flames for the ultimate in realism and ease of use.

There are two main types of gas log sets to consider: vent-free gas log sets that offer a superb balance between appearance and heating efficiency and vented gas log sets that create larger, more random flame presentations that come closest to a real wood fire.


GAS LOG SET DESIGN STYLES

Vent-Free Gas Log Set

Vented Gas Log Set


VENT-FREE GAS LOG SETS

Vent-free or ventless gas log sets are a great choice if you are looking for the highest heating efficiency possible. They’re a superb supplemental heating source when used in an approved vent-free firebox or wood-burning fireplace with the damper closed. Since vent-free gas logs produce moisture, it’s important they’re properly sized for the room you use them in. Download and complete the Air for Combustion and Ventilation Worksheet and check with local building codes to make sure a vent-free gas appliance is an appropriate option for your application.

Vent-free Gas Log Set Features

  • Use in approved vent-free fireboxes, and factory-built and masonry wood-burning fireplaces
  • Do not use in factory-built fireplaces that state unvented gas logs should not be used
  • No venting required; however, adequate air must be available for combustion and ventilation
  • 99.9% heat efficiency offers exceptional zone heating capabilities
  • Required oxygen depletion sensor (ODS) ignition pilot is included on all vent-free gas log burners that automatically shuts off unit if oxygen levels drop below an 18% safety threshold
  • Millivolt control models offer reliable on/off operation with remote control capabilities
  • Electronic ignition control models feature gas-saving intermittent pilot ignition (IPI) and seamless battery backup that provides continued operation in the event of a power failure
  • Wall switch, on/off remote controls, and multifunction remote controls are available for easy control of electronic ignition models
  • A variety of highly detailed logs available with realistic wood grain textures and colors
  • Outdoor-specific models with stainless-steel burners and grates are also available


VENTED GAS LOG SETS

Primarily chosen for decorative applications, vented gas log sets offer the ambiance of a traditional real wood fire with the convenience of gas. Since these log sets are only approved for use in fully vented wood-burning fireplaces that can withstand higher temperatures, they are able to burn with larger, more realistic flames and embers. Electronic ignition models combined with remote controls bring another level of convenience. Vented gas log sets also eliminate the work and mess associated with building, tending, and cleaning up after a wood fire.

Vented Gas Log Set Features

  • For use in fully vented and operational wood-burning fireplaces only
  • Fireplace must be operated with glass doors and damper in fully open position
  • Used in decorative applications due to low, less than 10% heating efficiency
  • Match-light models available for natural gas applications (safety pilot kits required for LP gas)
  • Electronic ignition control models feature gas-saving intermittent pilot ignition (IPI) and seamless battery backup that provides continued operation in the event of a power failure
  • Wall switch, on/off remote controls, and multifunction remote controls are available for easy control of electronic ignition models
  • A variety of highly detailed logs available with realistic wood grain textures and colors
  • Outdoor-specific models with stainless-steel burners and grates are also available
Tips for Safe Operation


Our Commitment to Safety

Superior products are constructed with the utmost care and precision and designs comply with national safety standards. However, personal safety begins with good fire management. The temperatures of surfaces in and around a fire can become extremely hot during operation. It is essential to monitor traffic around a Superior Fireplace to prevent burns and to protect the overall safety of your home and loved ones.

Tips for Safe Operation

  • Always read and follow the instructions for the safe use and maintenance of your Superior Fireplace.
  • Surfaces on fireplaces, stoves, and inserts get EXTREMELY HOT!
  • The glass on the front of a fireplace reaches EXTREMELY HIGH temperatures and can cause severe burns if touched.
  • Surfaces around the fire—especially glass doors or panels—can stay very hot for long periods of time after operation has ended. Be aware that surfaces may stay warm from a lit pilot light, even if the product is not operating.
  • Never leave young children or pets alone when operating a Superior Fireplace.
  • Educate your family about fire safety before you begin operating a new Superior Fireplace.
  • Use a firescreen (if applicable) for added safety.
  • Always keep a hearth product remote away from small children.

Free Safety Guard Offer for Superior Single-Pane, Sealed Glass Front Gas Fireplaces*

Superior Fireplace Safety Guards provide some benefit relative to reducing the severity of a burn or injury against severe burns and injuries by preventing direct contact with the front glass surface of your gas fireplace through the use of a formed mesh screen that stands off from the unit. It is easy to install and is removable. This screen is not decorative but rather a safety device that should be used when children or other at-risk populations will be near the fireplace. However, it is not a substitute for following all safety guidelines included in the care and operation manual accompanying your fireplace.

*Safety Guards may not be available for some older models, which are no longer in production.

Decorative Firescreens for Superior Fireplaces

Superior Fireplace makes several types of firescreens available for fireplaces. While wood-burning, factory-built fireplaces come equipped with wire mesh draw screens, Superior Fireplace offers for purchase decorative firescreens for Superior brand gas fireplaces with single-pane glass panel fronts. These include Screen Panel Kits or Screen Barrier Kits which provide a mesh covering that prevents direct contact with the hot glass surface. Although these screens provide some benefit relative to reducing the severity of a burn, they are not intended as a safety device.

Remember, Safety is a Responsibility with any Fire-Associated Product

Read and understand the information in the Homeowner’s Care and Operation Manual that accompanies each appliance. Refer to these tips regularly and review with those in your home to assure careful operation and long-lasting comfort.

Winner !!!
Color: Orange
This amazed us. For perspective, we're talking about a three year old white german shepherd who if he's in the mood, has and can kill a toy within minutes or oddly enough be gentle with furry balls and carry them around as if they are his babies. He's an odd duck. Anyway, since he was a pup, and to this day, he'll play and entertain himself, he'll grab a ball, throw it up in the air, then pounce on it as if it's from outer space. It's really quite cute and funny. Because of those two things I was looking for something interactive that would entertain him and confuse him....let's be honest, watching a confused dog is one of life's great pleasures. I tried two other interactive balls and they were crushed immediately. After reading a lot of reviews, people with german shepherds said this ball actually had a life span. I thought the third time could be the charm and ordered one. Well, I think it actually may be from outer space because he's obsessed with it and hasn't taken a bite out of it. He hasn't once chewed it or even teared little pieces off. The three settings are great. Sometimes he likes one better than another, then forgets about the others. I'll change it up to one he hasn't seen in a while and the whole game starts over again. He'll throw it up in the air as he does with his others, watch it and try to figure out which way it's going to go. And yes, he will pounce on it if he times it right. The size is perfect, it's heavier than your average ball but, that's what make it sturdy. I have to sneak it away when he isn't paying attention to charge it, otherwise he'll sit, stare and cry if he knows it's on the counter charging. It's a lot of fun for all of us. I'm so happy I bought it...... I say give this ball a chance even if you have a beast with killer instincts. I'm buying another for a friends 2 year old golden retriever granddog. Thank you Cheerble.

Great toy, too bad my Shih Tzu is afraid of it. I love the way the movement is subtle and random.

I wouldn’t recommend this for strong chewers.
Color: Orange, Color: Orange
Is it fun? Sure. Was it easy to charge and set up? Yep. That being said, this toy kind of fell flat for me. It really didn’t do any big movements once charged that I expected it to, so that was a bummer. I initially got it for my dog, but my cats were more interested in this than my dog was. The battery does seem to last a long time and the motor is pretty quiet. I WOULD NOT recommend this toy for strong chewers as the material for this is a foam rubber and I don’t think it’s durable enough for strong chewers. While the material makes this ball extremely lightweight for more movement, a strong chewer would have this disintegrated in five minutes flat. My Dog is a super strong chewer. I don’t think I would feel comfortable leaving him unattended with this because I know he would destroy it.
