The Two Types of Gas Fireplaces and Their Ventilation Systems


1. Direct Vent

When looking for a direct vent furnace, it’s important to decide what you want from your new unit before you make your purchase. You should consider how much heat your room needs, how much power it needs, and whether you’d like flickering flames or a more traditional look.

A direct vent fireplace gives you control over the height of the flames and can make a great alternative to a masonry wood-burning fireplace. This type of fireplace is extremely convenient to use. You can turn it on by pushing a button and it will warm up the room in minutes. No more chopping logs and starting a fire. You can also control the amount of heat that comes out of the fireplace with a timer.

Some models are also controlled by an app on your smartphone. A direct vent fireplace also reduces the risk of drafts. While a B-vent fireplace suctions combustion air from the room, the direct vent type of fireplace draws combustion air from the outdoors. This reduces the risk of cold drafts, which can make people feel even colder than they already are.

2. B-Vent

A B-vent furnace offers a variety of benefits over a standard fireplace. Most B vents have a traditional U-shaped burner and a square firebox, but you can learn more about that by clicking here. They also feature either an IPI or standing pilot system. The IPI system helps prevent cold starts and allows the unit to maintain a constant temperature.

It also turns off the pilot light after each use. If you have a B-vent furnace, make sure to follow the manufacturer’s instructions carefully. A faulty gas line can result in a house fire. Another concern with this type of fireplace is that the air flow is limited.

A B-vent furnace can also use fresh logs. However, you should remember that DuraFlame logs are not compatible with B-vent fireplaces. Another benefit of a B-vent fireplace is that it doesn’t produce as much air pollution as a standard wood-burning fireplace.

This makes it a great option for homes in tropical climates, where traditional fireplaces can cause a great deal of indoor air pollution. A B-vent fireplace can also be used in areas where wood-burning is restricted.

Recommendation: Intermittent Pilot System

With the help of an intermittent pilot system, furnaces can run year-round and use less gas. This new system eliminates the need for an on-off pilot light, which saves you money and energy. Instead, a spark ignites a temporary pilot flame that lights the fire. This is one of the reasons furnaces are becoming more efficient.

This system is a bit more complicated than a traditional one, so it’s better to have a technician perform the installation. It differs from a Millivolt system, which relies on a standing pilot light. According to this discussion: ( in contrast, an IPI system relies on an electronic ignition switch instead.

When using an intermittent pilot system, you need to make sure the thermostat is set to a lower temperature. If the thermostat doesn’t read this temperature, you may want to turn it off and use a continuous pilot. Another way to make sure your gas heater is operating at optimum levels is to regularly relight the pilot.


The cost of running a furnace depends on several factors. The first factor is how much fuel the fireplace burns, or BTUs. These units are equivalent to the amount of heat produced per pound of water. In general, the cost of running a furnace depends on the type of fuel used and the type of gas provider.

The other factor is the efficiency of the fireplace. A gas fireplace with a higher efficiency will require less fuel. This means that the appliance will last longer, and you will pay less in the long run. Energy-efficient, luxury gas fireplaces will run on less gas than an electric fireplace. Also, a fireplace with a lower efficiency is cheaper to run, but will not produce as much heat. 


When it comes to the installation of a furnace, homeowners should be aware that there are several things to consider. First, they must determine the best fireplace for their home. In addition, they should check local building codes to ensure everything is up-to-code.

These may have regulations regarding clearances around vent pipes and emissions. In general, there are three basic types of fireplaces: prefabricated, zero clearance, and direct vent. Installation of furnaces requires licensed professional, so no DIY projects for you.

A fireplace professional should be able to perform the work quickly and efficiently. Proper ventilation is essential to avoid fire hazards. The gas lines must be hooked up properly. If the fireplace uses a vent, it must be vented according to local regulations and safety standards.
