Piping your heating oil tank properly is essential for safe operation.
Piping your oil tank can be a learning experience.Piping your oil tank can be a learning experience.
A correctly installed tank has a vent and fill pipe and a mechanical fuel gauge. If installed in your home the vent and fill pipes need to be routed outside the house to a accessible area. These pipes should terminate well above the grade and in a location that will mitigate damage from automobiles and lawnmowers. With the right tools you can pipe your own oil tank.

Step 1

Set the tank on its side and attach the legs to their sockets with a friend's help. Tighten with the pipe wrench.

Step 2

Position the tank in a suitable location that meets your local building codes.

Step 3

Remove the cap on top of the tank that has no other cap beside it. Apply pipe dope evenly to the thread's of the oil gauge. Thread the oil gauge into the hole and tighten with a wrench.

Step 4

Remove the cap on the opposite side of the tank. Apply pipe dope evenly to the threads of the 2-inch pipe and thread it into the hole. Tighten with a pipe wrench. Install the fill cap on top of this pipe.

Step 5

Remove the last cap in the top of the tank. Apply pipe dope evenly to the threads of the vent alarm, 1 1/4-inch pipe and goose neck. Install the vent alarm in the hole, the pipe inside the alarm and the goose neck last. Tighten all three with the pipe wrench.

Step 6

Close off any other holes with the removed caps and pipe dope.

Step 7

Have the local building authority inspect the installation. Call an HVAC company to connect the tank to your furnace.
