My hotpot has a stand attached to it
You say you know what to cook in a Hot Pot and confirm that this product is identified on the body as a 'Hot Pot', but I think the issue may be that 'Hot Pot' means different things in different cuisines.
Where I come from a Hot pot is a lamb, potato and onion dish which is slow cooked in an oven. In East Asia it is a soup that simmers on the table while you cook morsels of ingredients in the broth. In India/South Asia, it is a vessel designed to keep cooked food warm until it is needed some hours later.

I suspect you were looking for a vessel suitable for the East Asian Hot Pot but what you have is an Indian Hot Pot.

This short advertising video includes a model called a ‘dome hot pot’ which looks very similar to the one you have., and the video description call these ‘insulated casseroles’. 

I can’t find explicit product details for an insulated hot pot with a ‘foot’ design, but insulated or double walled hot pots are for keeping food warm, not for cooking it. As an example here’s a Q&amp;A for a flat based version on amazon.co.uk

Also from Attila brand hot pot on Amazon:


  Do not place the Attila Hot Pot on hot surfaces or near open fire


So, if I am correct and you have an insulated casserole, I would recommend you only use it to keep food warm, and do not place it on a stove. 

Indicators that it is an insulated casserole/hot pot would be:
- Indian origin
- lock/clip lid to keep food tightly sealed
- thick side walls and lid indicating two layers of metal with vacuum or insulation between.
