Home owner has converted from oil to HE gas. Existing masonry chimney w/ tile flue is no longer in use. Should he permanently cap/seal off chimney or leave it open with hood/screening to allow it to breath out the top rather than possibly creating increased creosote smell in the house?

Providing exterior brick and joints were in good shape I would recommend that the flue be cleaned and then capped and sealed off.
Cleaning of the flue is inexpensive and gets rid of any flammable creosote.
If there was a fire in the house that spread to the flue, the left over creosote can burn at a very high temperature impeding fire crews.
Fully capping it off is a better way to go. If it is abandoned and just screened off some critters will find a way to get in and make there homes. It would also prevent wind driven rain from entering and now going... where?
Also, what is HE gas
