    Natural gas connection
    Iím adding a garage heater. Can the natural gas line be tied into an existing gas line (T joint) or does it need to run back to the steel pipe where the other gas lines originate?

    In most areas you can not do the work yourself and will need to get permits and hire a licensed contractor.

    The real issue is volume, if the T would reduce the volume so that neither would work properly

    In the event you do not hire a professional, you must be informed that any open flame appliance located in a garage must be installed at least 18 inches above the floor, as in the vent of a fuel leak, fumes sink to the floor level:
    NFPA 54: National Fuel Gas Code 2015

    Chapter 9 Appliance, Equipment, and Accessory Installation

    9.1 General.
    9.1.10 Installation in Residential Garages. Appliances in residential garages and in adjacent spaces that open to the garage and are not part of the living space of a dwelling unit shall be installed so that all burners and burner ignition devices are located not less than 18 in. (460 mm) above the floor unless listed as flammable vapor ignition resistant.

    Yes I will hire someone to hook up the lines but I just wanted to know where to run the line for them to hook up. Thanks

    Yep I am aware of all of that too. I just wanted to know where to run the line for a professional to hook up for me. I know this now. Thanks

    Another question on this. Is there a problem using 2 sections of tubing and joining them or do I need 1 continuous section of tubing? I need about 40 feet and was wanting to use 2 20 foot sections which costs much less than one 60 foot. (Can't find 40 foot section)

    ß 3280.705 Gas piping systems.
    3) Concealed joints: Piping or tubing joints must not be located in any wall, floor, partition, or similar concealed construction space. (i)Concealed joints. Piping or tubing joints shall not be located in any floor, wall partition, or similar concealed construction space.
    In an open space, connections may be made. I would use a ground joint union so you can open the piping if necessary. Check to see if your local utility allows right/left connectors. One reason you may not be allowed is that on a R/L fitting, when you tighten one side, you loosen the other. With a union that does not happen.
