Placement notes
Indoor oil tank clearances are governed by NFPA 31 and local code; requirements differ by jurisdiction and tank listing, so confirm specifics with your installer or AHJ. Practically, leave working access to the gauge, fill and vent, keep the legs on a solid level pad (a square footage calculator helps size the slab and figure concrete), and maintain the code-required separation from the burner.
