    What are the BTUs?
    1 Answers
    This item is a vent-free firebox only and therefore it has no BTU rating. You will need to purchase a multi-sided/see-thru ventless gas log set separately to complete installation. Your BTU output will depend on the log set you choose.

    So, this is free standing? How do you connect the propane? And, there's no ventilation? I am looking for a back up heating system for when the power goes out and would like to eliminate wood. Could this system work?
    1 Answers
    The unit is not a "freestanding" unit. It open on three sides. It is vent free, so there's no venting and it does require a vent free log set. That log set would then be connected to the LP and the valve on that unit would determine if it is able to operate without electricity.

    We have a flat roof and would like to add a fireplace to our home. I assume we would need ventless fireplace in order not to put a hole in our new flat roof. We have gas in the house so I assuming would could use our gas line to use for fireplace. Do you have 3 sided glass versus the screens? We are wanting to see the fireplace in 2 rooms.
    1 Answers
    We do offer peninsula direct vent gas fireplaces that may be vented horizontally with a minimum vertical rise. These models may be viewed here by selecting your gas type, peninsula and direct vent from the filters along the left side of the page. To answer your question, any ventless peninsula fireplace or firebox will not be covered with glass on three sides as ventless systems draw in their combustion air from the home. Sealing the fireplace or firebox would eliminate any combustion air that could be drawn into the opening, so most all ventless fireplaces or fireboxes will not be sealed with glass. Also, anything vented will require a hole to be cut through a wall or roof for the termination cap.

    Do you have this unit as a direct vent fireplace. I like that the screens open on this one rather than the glass sides.
    2 Answers
    Part of the operation of a direct vent fireplace will be that it uses sealed glass over all openings to prevent any room air used for combustion. I'm afraid that I do not have any other options to achieve direct venting.
    on December 12, 2016
    All direct vent fireplaces will be sealed with glass.

    How do I select a burner?
    1 Answers
    The burner will depend on the log set you choose, as this is just a firebox for which you need to install a gas log set.

    I am planning to install the 36" peninsula unit VRT43PFWS in my basement/family room. In framing out the peninsula wall, will the metal firebox take the wall load? The hearth will be raised on a platform with a porcelain finished base. Do you see any problem with that for heat transfer from the gas logs?

    I want to install this gas fireplace in my +/- 1800 SF manufactured home in Medical Lake, WA. What are the codes or restrictions I'll have to satisfy? Also, what is the output (BTUs) of this unit?
    1 Answers
    While the manufacturer, Superior, has listed and tested this firebox for installation within a manufactured home, local code may have more stringent rules and regulations in place. I would strongly suggest reaching out to local code enforcement first to ensure that this firebox meets their requirements. Being that this is simply a vent free firebox, it has no BTU rating alone. This firebox may accept most any vent free multi sided log set in either natural gas or propane. The BTU rating and heating capacity would be specific to the log set itself.

    Is this unit vented to the outside?

    This is a ventless firebox made for installing appropriately-sized see-through/peninsula ventless gas logs, which require no venting.

    Does "vent free" mean that there is no chimney? Would that put carbon monoxide into the room?
    1 Answers
    Vent free appliances use a burner system that is engineered to burn with nearly perfect efficiency. As a result, water vapor and carbon dioxide are the main byproducts. Vented appliances typically have some level of flame impingement, which is the reason a venting system is required. Vented appliances offer a more realistic appearance, while vent free units are more efficient.

    Can this be adapted/used with propane? Our home is in Florida and natural gas is nonexistent in this area. Are there any other fuels that can be utilized in this fireplace? What is the BTU rating and average length of burn time if propane can be used?
    1 Answers
    This firebox can be utilized with both natural gas and propane. The BTU output will depend on the separately purchased log set that you install into the firebox. Typically, a vent free appliance can only be operated in maximum intervals of 4 hours.

    What is the efficiency rating of this fireplace?
    1 Answers
    Because this product is a firebox only, it does not have a listed efficiency rating. However, the firebox is designed to house any brand of 24 to 30 inch multi-sided vent free logs. These sets will have a 99 percent efficiency rating by design.
