![]() ![]() Many other options including true refractory firebrick interior walls, firescreens, face plates and door trim to make the direct vent look more like a genuine wood-burning fireplace and better fit your decor. Features to look for include a desirable, realistic flame, automatic ingnition of the pilot light, and a blower and a thermostat are certainly welcome, as well. Other models have been designed for more varied installation applications with flexible (corrugated) type vent and fresh air pipes, that can be installed and run horizontally or vertically, some with "runs" of up to 20 to 30 feet, allowing considerably more flexibility in where they are installed. A round or square vent cap assembly can be seen on the outside wall of this type of unit. Some direct vent fireplaces need to be on an outside wall, with the fresh air and flue assembly running directly through the wall to the outdoors. Direct Vents typically have concentric venting assemblies including a smaller diameter center flue pipe and a larger, outer pipe, for entry of fresh outside for combustion. Some in the industry refer to these fireplaces as "balanced flue" fireplaces since the air intake and flue products are 'balanced' for them to work correctly. As always, check with local building code officials before installing a fireplace.ĭirect Vent Fireplaces - On the market over thirty years, these are becoming more and more popular with homeowners and builders, since they are sealed combustion units burning 'outside air', and many now are design-certified as heating appliances. Premium models include refractory firebrick interior walls to add to the realism, and trim. A unit with a dual or triple burner will usually have a more realistic burning flame pattern. As with an insert, look for realistic and adjustable flames, a thermostat and a blower to help circulate the air. Some of the newer models may burn outside air, and may be design certified as a heater-rated appliance and as such, these units would win favor by most discerning customers. In many cases, owners feel a cool air draft when they burn their B-vent fireplaces. These are falling out of favor in the last several years, since most B-vent units burn air from inside the room/house and most of the heat generated by the flames is lost out the B-vent (gas chimney flue pipe.) Every cubic foot of air that is goes out the flue is replaced by air coming in from outdoors, usually around non-airtight doors and windows or through other unsealed pathways for air leaks. Check local building codes before installing an insert.ī-Vent Fireplace - This is a type of gas burning fireplace that was popular in new construction throughout the 1970's and into the 90's, with 4, 5 or 6" double-wall gas vent pipes normally running up through a chase or through the ceiling and attic, then through the roof with a chimney cap. If a direct vent gas fireplace is planned, we suggest looking for one that is heater-rated, rather than simply a decorative appliance. A blower is a nice accessory or feature, as is a thermostat for automatic operation. In the case of gas or electric inserts, look for a unit that has realistic and even adjustable flames, and glowing ember effects. Generally, an insert increases the heating performance of a fireplace, since they sometimes burn outside air and are what's called a 'sealed combustion' (no room air loss), producing heat that is put into the room, or in the case of a vent-free gas or electric insert, they turn a heat losing fireplace into a real heat generator, with the heat coming into the room rather than heading up and out the chimney. There are also vent pipes, chimney components, chimney caps, fireplace accessories, and more.įireplace Inserts - typically a fireplace product (either electric, gas-fired or wood-burning) that 'inserts' into an existing wood burning fireplace. ![]() We know that you may want some basic information about fireplaces.įireplace Products include inserts, zero-clearance and masonry fireplaces, mantels, surrounds, hearths, gas fireplaces with B-vents, vent-free, and direct vent, wood burning, as well as outdoor fireplaces, many available in a variety of styles, including open front (only) view, see-thru, peninsula, and corner designs.
