I am an HVAC-R owner in Chicago and have no experience with fireplace units. I am currently considering purchasing a new natural gas ventless log fireplace with a blower option. I would like to know where my money would be best spent for a unit as described. I have about 24" from the wall to work with. I do not need a t-stat or remote nor do I want it. If I can get units without these options that would be my first choice. Where are some good places to start looking (online) and what units should I place at the top of my list. I have NO experience with fireplaces and would love to hear some input from the pros.
