Hoods are designed to deflect heat from wood such as a mantel. Check the installation instructions for your log sets to see if the mantel height requires you to install a hood.

Vent-free gas log sets can be installed in most masonry fireplaces, as long as the set's clearance and ventilation requirements are met. For installation in prefabricated fireplaces or fireboxes, follow the fireplace manufacturer's recommendations, as well as meeting the set's clearance and ventilation requirements. Refer to the log set's owner's manual to determine clearances and unconfined space requirements.

No. If the fireplace is designed for use only with gas, this is a very bad idea. The fireplace is not designed to withstand a wood fire. And the gas jets are not meant to come in contact with ash. This is a real fire hazard. It's possible your fireplace was originally a wood burning fireplace and has been converted to gas. In that case, it can be converted back. But you shouldn't burn would in it until that's happened.

Operating gas logs in a fireplace can be similar to burning wood in the fireplace. Yes you will receive some heat, but it is impossible to predict how much. Gas logs retrofitted to existing fireplaces are primarily for aesthetic benefit. They look great, provide a large yellow-orange flame and are not particularly efficient. If heat is your primary motive for retrofitting your fireplace you should consider a gas fireplace insert. Either way, you'll have something easy to use and maintain.

You will need to consult the operating guide for your particular fireplace model. If you use another manufacturer's gas logs, you need to maintain the clearances they specify. You can only install vented gas logs in our wood burning fireplaces. No. Installing vent-free (room vented) gas logs into our fireplaces presents a potential safety hazard as these fireplaces have not been tested or listed by UL or AGA for these applications.

instant, roaring fire with no logs to lug or mess to clean up is what makes gas logs a joy to own without polluting the air like a wood burning fire.

We recommend not moving the logs. Placement of the logs is critical to the operation and performance of the fireplace. Misarranged logs can result in operational problems. If you notice the logs have been moved during cleaning, contact a service person or check your installation and operating instructions for proper placement.

Lamartine cannot recommend the use of any one type of solid fuel for coal fires. Due to the introduction of "petro-chemical" fuel with a high pep coke content, we have discovered that these fuels can cause serious damage to fireplaces, firebacks, baskets and hearths. These solid fuels can burn at extremely high temperatures, which no fireplace material at the moment can withstand. Please consult your local coal merchant for the correct fuel to use.

There are several different types of gas logs. Most of our members deal with the most popular types, vented and non vented or heating logs. The differences between these two logs sets is very technical. But to boil it down, Vented type logs can only be used in fireplaces with a working chimney that meet current codes. The damper is locked open upon installation must be kept open when burning. Placement of the logs can be changed to make the fire look different.

Gas log sets are designed to be installed into an existing fireplace, while gas fireplaces are self-contained units. Gas log sets are significantly less expensive but are considered a decorative appliance because they provide less heat.

Most vent-free gas logs use less gas than vented gas log sets, but will provide more heat in the home, since none of the heat is vented to the outdoors.

If you have a fully operational fireplace, whether masonry or pre-fab, it would normally be as simple as removing the gas logs & capping the gas line or installing a gas log lighter. But with today's new appliances, direct vent & ventless units would not be set up for solid fuel (wood) & could not be converted to wood burning.

There are many types of synthetic (manufactured) logs on the market. You need to carefully read the instructions on the packaging. Those instructions should clearly mention whether the logs are approved for use in a fireplace (freestanding stove, zero clearance fireplace, or fireplace insert). If there is no restriction mentioned on the packaging, try to contact the log manufacturer. Some types of synthetic logs are forbidden for use in freestanding stoves.

No. Very few vented logs are certified for use with a blower. Heatmaster vented logs are not. However, if your fireplace has a built-in fan system, this can be used.

EPA Regulations are government regulations of wood burning appliances mandating that products sold after July 1, 1992, emit no more than 4.1 grams of particulate matter per hour for catalytic-equipped units and no more than 7.5 grams for non-catalytic-equipped units. When starting a fire, use plenty of crumpled newspaper and kindling. As a guide, fill the firebox completely with loosely crumpled newspaper and hold it down with at least ten pieces of finely-split dry kindling.

No. Vented and vent-free logs are different in many ways. Heatmaster vent-free gas logs are also certified as vented (with the exception of the thermostat models), but the vented logs must always be vented.

Since CBM travels with ground water in coal seams, extraction of CBM involves pumping available water from the seam in order to reduce the water pressure that holds gas in the seam. CBM has very low solubility in water and readily separates as pressure decreases, allowing it to be piped out of the well separately from the water. Water moving from the coal seam to the well bore encourages gas migration toward the well.

With the exception of the K Series*, the answer is no. The airflow technology that we use in our amplifiers is designed such that it is best to stack multiple amplifiers on top of each other, with no space between. The amplifiers draw fresh air into the front of the amplifier and exhaust it either out the sides and into the rack, or out the back depending upon the model. We want the hot air that is in the rack to vent out the sides or back, not the front.
