Why is there film on the glass of my gas fireplace?
This is a normal result of the curing process of the paint and logs. Glass should be cleaned within 4-6 hours of initial burning to remove deposits left by oils from the manufacturing process. A non-abrasive cleanser such as Brasso may be necessary.
If I install the optional fixed glass doors on gas fireplaces, do I have to leave the glass panel and screen in place?
The glass panel must remain in place but the screen will be removed so that the fixed glass doors will not fit on the unit.
What is the difference between a Direct Vent unit and a B-Vent unit?
A direct vent fireplace is a sealed unit that gets its combustion air from outside of the home. The direct vent pipe can vent either vertical or horizontal and can use elbows to go around obstructions. B-Vent units use combustion air from the home but can be enhanced with an outside air kit. B-Vent pipe must terminate vertically and you must follow the installation instructions of the B-Vent manufacturer.
Is it okay to burn wood or other materials inside a gas fireplace?
No other materials may be burned inside a gas fireplace. The gas fireplace is designed and certified by UL specifically to burn only LP or Natural Gas. Burning wood has a much higher peak temperature that can not only permanently impair the fireplace itself, but also provide a real fire danger to your home and occupants. Even something as simple as burning paper can harm the fireplace's internal controls and possibly overheat and break the glass
How do your gas fireplaces vent?
The majority of Hearth Technologies gas fireplaces and inserts are direct vent (DV). This means they have a fixed glass front which seals the gas burner and combustion firebox off from your home. 100% of the combustion air used by the fireplace comes from outside the home through a coaxial pipe. A smaller pipe inside the larger pipe eliminates all combustible gases, maintaining indoor air quality. The vent can be run horizontally through an outside wall, or vertically through the roof, depending on your preference.
What is the cost to operate?
This varies by region, by gas
utility and by fuel type. Based on national averages, a gas
fireplace consuming 27,000 BTU's per hour will cost from 12-15
cents/hour to operate. LP units are slightly higher to operate.
Your monthly gas bill should include your exact cost per therm
(100,000 BTU's). Based on this rate, and the BTU input listed on
the rating plate on your fireplace, you can calculate the cost
for your area.
How much gas
does the pilot light use?
This will vary by region, by gas
utility and by fuel type. The pilot is consuming 600 to 900
BTU's an hour. Your monthly gas bill should include your exact
cost per therm (100,000 BTU's). Based on this rate, you can
calculate the cost for your area.
Can I shut the
pilot off in the summer?
Yes, or you can safely leave it
burning. The pilot helps keep the moisture from inside the
firebox, which is caused from the humidity in the air. It also
will extend the life of the thermopile and thermocouple when the pilot is left on.
Is “direct vent” the same thing as “ventless”?
No. Direct vent fireplaces use a sealed glass front to completely isolate combustion gasses and moisture from your home. This is especially important in new construction homes that are built very tightly to comply with today’s energy codes. Ventless fireplaces are designed to expel combustion gases and moisture directly back into the room. Ventless or unvented are illegal in many states and municipalities.
Does a direct vent need to be on an outside wall?
No, with today’s venting options, hearth products can be installed very economically almost anywhere in the home.
What are the advantages of the direct vent fireplace?
Direct vent technology is available in single-sided or multi-sided fireplaces, as well as freestanding and insert models. They use a sealed combustion chamber that vents out the back or top, to the outside. This allows easy installation of a beautiful and realistic fireplace without the expense of a traditional chimney system. Because no room air is used for combustion, direct vents are especially efficient (up to 70+%) and will not alter the quality of your room air. All combustion air is drawn from outside the home and 100% of the combustion by-products are exhausted to the outside.
Can a blower be added to my fireplace, gas or wood?
Blowers are optional on most heat circulating (grilles on top and bottom of fireplace) units, and some hearth products the blower is standard. Adding a blower is easily accomplished if power (110 VAC) was provided to the electrical junction box of the fireplace at the time of initial installation. If power was not provided, a fan option is still possible, but installation is complicated and therefore more costly. Contact your local dealer to determine if your particular fireplace model and installation will accept an optional blower.
Who would install the gas line?
A licensed contractor or plumber can install your gas line. Check the yellow pages or contact your nearest dealer for a recommendation. Find the stores near you.
What are my options for gas fireplaces besides direct vents?
Non-sealed combustion models are also available (B Vents) when a direct vent installation is impractical. Direct vent models are the preferred system for the benefits of greater efficiencies and the sealed combustion chamber.
Does the fireplace come in LP gas?
Yes. Some models can be ordered as either a natural gas or LP unit, or an LP conversion kit can be ordered with the fireplace.
What happens if I lose my electricity?
As long as your gas fireplace has a standing pilot ignition system, it will still operate during a power outage. (Some electronic ignition fireplaces will not operate without electricity.) Since the fan requires 110VAC to function, it will not be operable in an outage. NOTE: If you have a remote control on your fireplace, you most likely will need to turn your fireplace on manually during a power outage. This is done by locating the ON/OFF rocker switch located behind the lower grille of your fireplace, and turning it to the ON position.
Can the gas fireplace be installed in a bedroom?
Yes. Most building codes allow the installation of a gas fireplace in a sleeping room as long as it is a sealed combustion, direct vent model.
If I want to convert my woodburning fireplace to gas, is a set of gas logs or a gas insert going to be my best option?
Your decision really comes down to whether heat or aesthetics is your number one priority.
If heat is your first concern, or the existing wood fireplace has had a history of down drafting (smoking), you should purchase a gas insert. If your wood fireplace vents properly, and you’re not really looking for additional heat into the room, gas logs would be the logical choice. From an initial cost standpoint, an insert will cost 4 to 5 times more than a set of gas logs. However; since decorative gas logs are inefficient and a direct vent insert has an operating efficiency in the 70% range, your payback on the fuel you will save is about five years. After that the insert begins saving you money.
I live in a warm climate and I don’t want heat. What are my options?
Too much heat can sometimes be an issue even in colder climates. There are several fireplace models which allow you to control the amount of heat coming into the room. These units have a simple control which sends more or less heat out the venting system. Some models also have the option to duct heat to a different room (heat-zone) or into the home's heat circulation system (heat-duct). Electric fireplaces are also available which have the option to provide heat or the heat can be turned off.
How often do I have to clean the gas fireplace and vent?
Although the frequency of your fireplace servicing and maintenance will depend on use and the type of installation, you should have a qualified service technician perform an appliance check-up at the beginning of each heating season.
