Confirm lamp dimensions, hanging or standing method, glass-cup size, wick system, and the type of oil recommended. Replacement cups and floats are not universal, so compare measurements carefully. A hanging lamp also needs chain length, ceiling support, and safe clearance from walls, fabric, and icons.

Use only suitable oil and follow the maker's fill and wick instructions. Keep every flame attended on a stable, heat-resistant setup away from children and pets. Installation of suspended lamps may require appropriate anchors or professional help. Keep spare glasses, wicks, and cleaning instructions where parish or household users can find them.
