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 damper must be fixed open to pro- vide a minimum of 32 square inch of free air opening at all times during operation of the log set. A damper clamp is included to secure the damper.

The minimum flue sizes shown in Figure 3 are based on a 6' chimney height using round pipe. Your minimum flue size will vary based on input rate and chimney height. Refer to the National Fuel Gas Code ANSI Z223.1/NFPA 54, Section 6.6 for details.

INSTALLING DAMPER CLAMP

Secure the damper stop clam to the edge of the

damper as shown in Figure 4. If for any reason

this clamp doesn't work on your fireplace, another

suitable clamp or permanent stop must be installed,

or the damper blade must be cut or removed.
