INSTALLING VENTED APPLICATIONS

Manual and Millivolt 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.

WARNING

This appliance is for installation only in a solid fuel burning fireplace (masonry fireplace or manufactured fireplace) with a working flue and constructed of noncombustible material.

Exception: DO NOT install this appliance in a factory-built fireplace that includes instructions stating that it has not been tested or should not be used with unvented gas logs. This log set may be installed as a vented log set.

Before installing the appliance:

•Turn off gas supply to fireplace or firebox.

•Have the fireplace floor and chimney professionally cleaned to remove ashes, soot, creosote or other obstruc- tions. Have this cleaning performed annually after installation.

•Seal any fresh air vents or ash clean-out doors located on floor or wall of fireplace. If not, drafting may cause pilot outage or sooting. Use a heat-resistant

sealant.

Install and operate the appliance as directed in this manual.

Damper stop installation:

A damper stop must be provided with the unit. Contact your dealer to obtain one. The damper stop must be installed as shown in Figure 12 to prevent full closure of the fireplace damper blade and provide a minimum 29 square inch flue opening.

WARNING

The fireplace and gas logs function as a system. If the fireplace is spilling into the room (check with a match or a smoke stick), reposition the damper clamp until a positive draft is obtained by opening the damper. If negative pressure in home prevents having a positive draft, contact your dealer for assistance.
