    I am a novice plumber but farly skilled mechanic.

    I would like to install a gas fired garage heater that would be suspended from the garage ceiling. A 3/4" black pipe gas line has been roughed in (by others)from the basement which is integral and on the other side of the garage wall. The rough in includes a shut-off valve, a "T" fitting with a nipple in each end.

    The heater unit requires min. of 2' clearance from ceiling & 1.5' clearance from the walls.

    The unit will vent with 4" pipe directly out of the rear wall.

    Questions: Would it be better to finish the gas piping with rigid pipe or attach a flex line? (not sure if this is a code specification)

    Am I correct in assuming that the lower nipple in the "T" fitting is a means of draining the line in case of water accumulation?

    Can anyone offer any tips to avoid problems or things to beware of?

    Thanks in advance.

    The "T" fitting on the gas line is a sediment trap, rarely is there ever any accumulated sediment but some codes require it. Local code will determine the type of gas connection, whether it needs to be solid or a flex connector should be used. Venting is also extremely important including the type of flue piping used. This type of work may also need to be filed, inspected and approved by the Building Dept.

    Most of those heaters still have to be vented out through the roof. A strong breeze blowing from the direction of the side wall vent pipe, could create a backdraft and cause the burned gases to vent into the building or blow out the pilot light if the unit is not operating.
