    Can you install a natural gas regulator at the bottom of the gas fireplace by the gas valve?
    1 Answer
    A gas regulator should be installed on the line prior to the valve. I have seen it installed in that lower compartment area, yes. You should check with local code enforcement as well to ensure that meets local code.

    In your guide to gas logs, it says you have to use a damper clamp for vented gas logs. Does this mean the damper must remain open or partially open all the time? 

    1 Answer
    Yes, the damper clamp will hold the damper open just enough to safely allow the exhaust fumes from a pilot light to escape up the chimney.

    Can a freestanding direct vent fireplace sit directly on linoleum wood type flooring?

    1 Answer
    Most do not permit the unit to be installed on carpet or linoleum. You can place a stove board beneath the unit for a safe installation.

    How do I replace a thermocoupling?
    1 Answer
    Replacing a thermocouple is usually simple but it does vary in difficulty a bit from application to application.  For that reason, and to ensure the compatibility of a replacement thermocouple, we recommend contacting a local plumber, gas fitter or HVAC professional.

    How does vent free work?
    1 Answer
    Vent free gas systems operate at a 99.99% efficiency rating, so the only byproduct of combustion is water vapor and carbon dioxide. Because of this, it is not required that venting be used with a vent free fireplace or log set.

    I recently purchased an Empire DVD-36-FP30N from you. I'm installing in carpeted basement with concrete underneath carpet. I assume I cut the carpet away before installing fireplace unit and the unit sits directly on the concrete floor. Correct?
    1 Answer
    That is indeed how the unit should be installed.
