VENTING SPECIFICATIONS FOR INSTALLATION

The fireplace chimney flue and vent must be draft- ing properly. To check the vent for proper drafting: Light a tightly rolled newspaper on one end and place it at the inside front edge of the fireplace. Observe the smoke and be sure the vent is properly drawing it up the chimney. If the smoke spills out into the room, extinguish the flame and remove any obstruction until proper venting is achieved.

The chimney flue must remain open a minimum of 3" at all times during the operation of this log set.

Installing Damper Clamp

Secure the damper stop clamp to the edge of the damper as shown in Figure 3. If for any reason this clamp doesn't work on your fireplace, another suit- able clamp or permanent stop must be installed, or the damper blade must be cut or removed.
