Can a propane heater be used for natural gas?

It can be converted. Each heater can be very different in how this is done. You will need a conversion kit for NAT to LP and it will come with instructions and you owners manuel will be a lot of help while your doing this also.
When you go to order the kit you will need the full model number and serial number. If you have it the year the heater was built also.
