Is a ventless gas fire place with blower safe people are telling me it will be a lot of gas smell from it and they say its dangerious please help

Lot of gas smell? No. Some smell? Yes but not gas. Safe? Not as a primary heat source. As a supplement OK. Some states do not allow sales of unvented logs. Make sure to get a CO monitor.

Working normally or not, unvented fuel burning appliances are dangerous.
