    For gas logs, do we have to have vents or can we purchase "vent free"?

    By Kevin E. - NFI Certified Specialist on February 6, 2014

    As a resident of California, you would need to purchase a vented gas log set. This is simply due to the fact that California prohibits the installation of vent free appliances. Vented log sets require a complete, working chimney.

    I'm wanting a corner wood burning fireplace but need a firebox smaller then 36 inches. It needs to be 32 inches or less. In my home in Texas we had a gas firebox that we converted to a wood burning with a gas starter. Can you buy a direct vent firebox (they come in smaller sizes) and do the same thing? I was told you could but now I live in Colorado and I am having problems with people understanding what I want. I do not want a blower for heat just for ambiance and to smell the wood burning, not a heat source..
    By Collin C. - NFI Master Hearth Professional on September 3, 2013

    I am not aware of a direct vent gas fireplace that can be converted for use as a wood burning fireplace. Gas fireplaces lack the insulation, reinforcement, and depth to be safely operated with wood.

    Unfortunately, the wood burning units that we offer are no smaller than 36 inches in width. A width under 36 inches is rarely called for, so the manufacturers we work with simply do not produce this size. I apologize that we do not have a product for your needs.

    Does anyone make a blower less electric fireplace? I do not want the heat to blow but I do want heat.

    By Collin C. - NFI Master Hearth Professional on March 4, 2013

    I have not come across a brand that does not use a fan to help convect the heat. Because the heating element is sealed inside the unit, the fan is necessary to push heat from within the casing into the room. Many models exist that allow the light effect to work on its own, but the heater and fan will always work together.

    By Scott from NJ on November 1, 2014
    I am looking for the wood burning sealed units that are installed into a new framed construction. They pull air from outside to burn and circulate air with a fan to heat. Someone called them "positive pressure systems" but I don't know. Some have a catalytic converter in them to recirculate and re-burn gases. What would you suggest?
    By eFireplaceStore on November 3, 2014

    We offer a few of these systems, although they use a secondary air recirculation system with baffles, in place of a catalyst. The most popular item is the Flame Monaco XTD EPA Zero Clearance Wood Burning Fireplace. Other systems with more facing options are the Superior WCT4820 Custom Series EPA Phase II Circulating Wood-Burning Fireplace, the Superior WCT6820 Signature Series EPA Phase II Circulating Wood-Burning Fireplace, and the Superior WCT6840 Signature Series EPA Phase II Circulating Wood-Burning Fireplace.

    How do you remove a Heatform firebox from a masonry fireplace?
    By eFireplaceStore on November 14, 2014

    Most Heatform fireplace boxes had overlapping masonry on the front and upper edge of the unit. Because each installation is different, I recommend having a mason come out to inspect the setup, as some installations actually relied on the metal chassis to support the brick veneer.

    I have a gas fireplace which is vented through the chimney. The fireplace is not sealed. During a recent power failure I used it but it does not throw any heat in the room; you only feel it if you sit in front of it. What do I need to do to make it an efficient fireplace and a supplemental heat source?
    By Kevin E. - Fireplace Specialist on February 21, 2013

    The best way to make an open fireplace an efficient heating appliance is to install a wood burning insert. The chimney will likely need to be relined to vent this new appliance but the insert will produce truly usable heat.

    I have an opening for electric fireplace, that currently has an electric heater with a mantle surround. There is no firebrick. What do I need to change for an unvented gas logs?
    By Brennan W. on January 6, 2017

    In order to change to unvented gas logs, you would need a full firebox that could contain them and would fit in your opening.

    Do you offer a 4' x 6' firebox?
    By Collin C. - NFI Master Hearth Professional on August 20, 2013

    My apologizes, but we do not carry a premanufactured firebox of this size. Because of the very large dimensions, this type of unit would likely need to be custom made and listed by a fabricator.

    We purchased a vent free fireplace log unit and have not hooked it up yet. What kind of firebox will we need?

    By Will M. on October 18, 2016

    The minimum hearth dimensions will be described in the installation manual included with your ventless log set. You should choose a ventless firebox that meets or exceeds these minimum requirements.

    Can you buy a woodburning fireplace Firebox and use a gas log in it?
    I want to be able to pull the gas log out if I ever decide to burn wood.

    By Will M. on February 13, 2017

    Any of the open combustion Wood Burning Fireplaces we offer may be used with a vented or (in most cases) vent free gas log set. Should you ever decide to burn wood, the gas line would need to be shut off and capped.

    By Gwen from Centralia, Illinois on December 31, 2016
    I need a fire box that will fit an opening 33" x 27" opening and it has to be 15" deep. It also angles to 27" at the back.
    By Will M. on January 2, 2017

    Please note that the products advertised in this product category are designed to be framed in with combustible framing and used with separately purchased venltess gas logs. As it sounds like you may have an existing prefabricated wood burning or masonry fireplace, the hearth systems offered here may be better suited for your needs. If you indeed are in need of a ventless firebox, please provide clarity for your application and we will look into locating suitable fireboxes.

    Can your gas fireplace inserts be used and shipped to California?
    By Collin C. - NFI Master Hearth Professional on March 11, 2013

    California has strict guidelines for installation of both gas and wood burning fireplaces. Vent free appliances are not allowed by law and wood burning fireplaces must be EPA Tier II certified, meaning that they have an output of 7.5 grams or less of material per hour.

    While we can ship most of our units to all 50 states, local code will often prevent non certified units from being installed in your state.

    How does one install the natural gas pipe into the firebox?
    By Brennan W. on October 26, 2016

    Generally, the gas line is run into the unit by means of a knockout on the side of the fireplace.
