IS THERE A DANGER OF CONDENSATION AND CARBON MONOXIDE WITH VENT-FREE APPLIANCES?

Improper use of a gas appliance usually involves one of two misuses:

• not sufficiently venting the room or area by cracking a window or keeping a door open to a wider area
• running the appliance continuousl

If you misuse a vent-free gas appliance you can develop a situation that certain people who complain about vent-free heaters themselves cause: condensation.

A vent-free gas appliance must breathe. They need a fresh oxygen supply, and this is best accomplished by cracking a window, even in winter. The ventilation of the room and proper function of the heater or logs more than compensates for the letting in of outside air, even in the winter, and will not affect the ambient heat of the room.

Carbon monoxide in any measurable amount is not generated by a vent-free gas appliance. Carbon monoxide can occur, though, if the room or space where a vent-free appliance is running ISN'T being ventilated properly. Carbon dioxide can accumulate over a long period of time in an unventilated space, and then the flame of the vent-free appliance begins to convert carbon dioxide to carbon monoxide. This should NEVER occur if a vent-free appliance is installed and used properly.
