What is the difference between a millivolt fireplace and an IPI fireplace?
These terms are often mentioned, but rarely gone into with depth and clarity. A millivolt gas valve is a common apparatus that is used in many types of gas appliances. It operates by utilizing a valve containing an electromagnet, attached to a plunger that controls gas flow. Within the combustion chamber and usually directly above the burner is a pilot assembly, which consists of a small gas tube, a thermocouple or thermopile, and an ignitor in most cases. A thermocouple is a small metallic probe that contains a juncture of two dissimilar metals. When heated, the resistance between the metals creates a very small amount of voltage. A thermopile is simply a larger version of a thermocouple and contains multiple chains of these linked junctures. A millivolt style of fireplace will have a manual push knob that initiates the flow of gas to the pilot tube. Utilizing the push button ignitor or a manual lighter, the gas exiting the pilot tube will ignite and begin to heat the thermocouple or thermopile. The resulting voltage being generated will travel back to the gas valve via a copper lead, energizing the electromagnet in the valve. When fully charged, the manual push knob can be released, allowing the pilot to remain lit and the appliance to commence operation. Voltage generated by the pilot is all that is needed for the appliance to work, making this a great low maintenance fireplace, at the cost of a small amount of gas being consumed. An IPI (intermittent pilot ignition) appliance has similiarities to a millivolt appliance. It still uses a gas valve and pilot assembly, but the pilot is not always lit as with a millivolt appliance. Instead, the appliance only lights the pilot when the system is calling for operation. When switched on, an electric spark ignitor begins to fire at the pilot assembly until the flow of gas coming from the pilot tube lights. The flame from the pilot heats a flame rectifier, which is similar to a thermocouple. Instead of generating voltage like a thermocouple, a flame rectifier generates a signal that is sent back to a control module in the appliance. When the module detects the signal, the computer logic tells the ignitor to stop firing and the gas valve to open, commencing operation of the burner. When the system is switched off, both the burner and pilot extinguish, saving fuel by not allowing a pilot to burn while in standby. This type of system usually relies on 120 volt power as a primary supply, with batteries as a backup. In recent years, IPI systems have become very reliable and are on track to outsell millivolt systems in the near future.

What is the difference between a vent free fireplace and a direct vent fireplace?
While they share some basic operating principles, there are several differences between these two appliance types that govern where they may or may not be installed. Direct vent appliances utilize a sealed combustion chamber that ensures they do not consume any oxygen from the room. The chamber is sealed with a gasketed pane of tempered or ceramic glass, which is held in place by bolted or spring loaded clasps. The log set is contained behind the glass and can easily be viewed through it. The direct vent pipe facilitates both the emission of burnt gases to the atmosphere and the intake of combustion gases to fuel the fire. Typically, the inner pipe is responsible for exhaust duties, while the outer handles combustion air. The pipe can be vented vertically and even horizontally, over limited distances. Because of their sealed nature, restrictions on installation are few and far between, with the primary limitation being the need for the vent pipe run. Like direct vent appliances, vent free units use a gas valve and burner apparatus, coupled with a log set, fire stones, or fire glass. However, vent free units use no venting system or glass front. They are able to do this due to a strict limitation on BTU output and requirements imposed on the media they can use over the burner. Because they do not require vent pipe, they are extremely versatile in how they may be installed, however they also have state by state limitations. In states where they are allowed, they can be a fantastic supplemental heat source for limited durations.

Why are gas fireplaces with direct vent from the top more expensive than vent free? Seems counter intuitive. I have a gas fireplace from the 80's and it needs to be replaced. Do I really need to spend $3000.00 dollars for sheet metal lined with ceramic bricks?
Direct vent gas fireplaces are more expensive due to the cost of manufacturing, the solid glass front utilize and the engineering involved. Please note we do sell many models in the $1,100-$1,200 price range; the $3,000+ models are typically the high-end luxury models with many bells and whistles.

For a Majestic model# 39BDVR RN fireplace, where is the thermocouple located and what does it look like?
The thermocouple will be attached to your pilot assembly. It is a small cylindrical piece of metal that is being heated by your pilot light.

from Suffolk, VA asked:
November 14, 2017
I have a 14 year old Majestic fireplace model# 39BDVR RN with a SIT Nova control knob. When I tried to light the pilot this year, it would not stay lit. I turned the control knob to pilot and lit it with the ignitor switch, held the knob in for 1 minute and released the knob and the pilot light would not stay lit.
Your thermocouple is likely not recognizing the pilot flame, which is causing it to shut off when you let go of the knob. You will want to clean the thermocouple with a piece of emery cloth or high grit (1000) sandpaper. This should resolve the issue.

I have a fireplace with a Heatilator to burn wood. It is double walled steel and in between the walls is an air space that circulates the warm air. This has a damper leading into a masonry chimney with a smoke shelve. If I get a vented gas log fireplace and open the damper about 1/2 to 1 inch, would this be sufficient for a 50 to 70 k BTU log set?
You are advised to open your damper completely when using a vented gas log set.

I have an existing un-vented fireplace. Can I change it to vented? It has to sit against an interior wall.
A vent free firebox can not be converted to a vented one, but can be replaced by a vented unit. Installing a direct vent on an interior wall is not an problem.

November 29, 2016
I am building a house and want to put in a fireplace. My contractor told me to pick out a direct vent fireplace because there is no chimney. But now I am seeing different options such as ventless fireplaces. Do they have real flames. Do they need a gas line. What is the difference? If I can avoid the cost of running a gas line, that would save money
Ventless gas hearth systems will still require a plumber or gas fitter installing a gas line, but they do not require any venting. Initially, the installation cost will subsequently be less than that of a direct vent system, however, these systems are not allowed in all municipalities and do require maintenance more frequently than direct vent systems. If the concern is initial cost, one consideration should be an Electric Fireplace
as not venting would be needed and this would not require a plumber or gas fitter.

Can I keep the fireplace glass doors closed while burning a vented gas log set?
As long as the doors do not use gaskets to seal them, yes. I highly recommend leaving the doors open for at least the first 15 minutes of operation to ensure that the glass is warmed slowly. This will prevent the possibility of glass breakage, due to thermal shock.

November 22, 2016
Where can I find a gas shut-off valve for a glass fireplace set?
If this is simply a natural gas vented burner, this may be operated with the manual key valve that should be installed in the wall or floor outside of your fireplace opening. If this is liquid propane, a safety pilot valve must be installed. In either case, we will need to have the make and model number of the burner to locate a compatible valve.

from Mill Creek, WA asked:
November 5, 2016
How do you go about removing the glass so as to clean behind it?
While it depends on the brand, almost every direct vent gas fireplace requires that you first remove the upper louver assembly, then flip down the lower louvers. There should be 2 or 3 spring loaded clamps that will be visible along the bottom of the glass door frame. They can be pulled forward and dropped down out of the way, allowing you to tilt the glass forward at the base and then lifted up and out of the way. Some older units did not use spring loaded clasps, instead requiring you to loosen bolts that run along the base of the frame.

December 10, 2013
Is there any regulation regarding how close to a window you can place a gas(propane) fireplace?
By national code for direct vent fireplaces, the edge of the vent termination can be no closer than 12 inches to a door or a window. Most terminations are approximately 12 inches across, so the center line of the vent passing through the wall would need to be approximately 18 inches from the edge of the nearest door or window.

When a fireplace is advertised as a 24" or 32" fireplace, does that just mean the box? Or the complete unit with surround?
This varies from manufacturer to manufacturer. By and large, the measurement refers to the front width of the fireplace face, including the sides, but in other cases it is the opening measurement. For every fireplace on our website you can download the owner's manual and see the illustrated dimensions which will clarify this.

Whats the difference between a "fireplace" and a "firebox"?
Generally, when an item is listed as a "firebox," it will not include a gas burner or a log set, whereas a "fireplace" will include the firebox, the burner and the log set. Every unit on our website should clarify what is included.
