Gas Logs
Do you know?
how to tell the difference between vented and unvented gas logs
Vented gas log sets
Vented gas logs must be vented through a functional chimney in order to move all burning by-products outside the home. Vented gas logs produce the most realistic flames but put off less heat than their vent-free counterparts due mostly to the fact the chimney flue must be open when the fireplace is in use. This is why vented gas logs are usually considered decorative appliances, so if aesthetics are your primary concern when renovating a fireplace, a vented unit is likely your best choice.
Vented gas log sets
Ventless gas logs do not require any special venting to use, only an approved firebox. As a result, these units can be used in an existing fireplace installation with the chimney flue closed or in installations with no chimney at all. Vent-free gas logs are the best option for heating due to the fact all heat is put back into the room and not lost up a chimney. Although uncommon, vent-free fireplaces are prohibited in some states and jurisdictions, so be sure to check your local building codes before installing a ventless fireplace or gas log set.
