INSTALLING VENTED APPLICATIONS
Manual and milli-volt controlled gas logs may be installed as a vented decorative log set in compliance with ANSI
Z21.60 and National Fuel Gas Code, Section 6.6. Since, the gas logs are operated with the damper open,
non-combustible material and minimum mantel requirements do not apply.

tions. Have this cleaning performed annually after installation.

draft is obtained by opening the damper. If negative pressure in home prevents having
a positive draft, contact your dealer for assistance.
