    Dan Wellman here... I think that Talia is confusing LP (Propane)
    with Natural Gas. Her statements are true with regards to LP but
    allowances are made by code for LP in basements provided it meets
    local code requirements. Think of the many water heaters, furnaces,
    boilers etc. that are in basements. All of them have safety systems
    to prevent a build up of gas in the basements. Natural Gas is Lighter
    than air and rises out a vent / chimney etc. As a practical matter
    the valves on the torch will function to regulate the gas flow to the
    tip and an in-line regulator is probably not necessary. I would
    advise that a locally licensed installer put in the gas line. They
    should know the local code and install it to meet those standards at
    a minimum. An extra safety shut off in the line may be required. Most
    UL or FM (Factory Mutual) standards require some kind of automatic
    shut off to protect against the torch being left on slightly and
    leaking etc.  I would recommend an automatic shutoff station where
    you hang the torch on a shutoff arm and that shuts it down. Most of
    these have a small pilot flame so that there is an easy relite when
    the torch is picked up. Also bear in mind that your insurance may
    have even stricter standards.
