After the

Installation

Before lighting the fireplace, be sure to do the following:

Remove all paperwork from underneath the fireplace.

Review safety warnings and cautions

Read the Safety and Warning Information section at the beginning of this Installers Guide.

Double-check for gas leaks

Before lighting the fireplace, double-check the unit for possible gas leaks.

Double-check vent terminations.

Before lighting the fireplace, double-check the unit for possible obstructions that could be blocking the vent terminations.

Double-check for faulty components

Any component that is found to be faulty MUST BE replaced with an approved component. Tampering with the fireplace components is DANGEROUS and voids all warranties.

A small amount of air will be in the gas supply lines. When first lighting the fireplace, it will take a few minutes for the lines to purge themselves of this air. Once the purging is complete, the fireplace will light and will operate normally.

Subsequent lightings of the fireplace will not require this purging of air from the gas supply lines, unless the gas valve has been turned to the OFF position, in which case the air would have to be purged.

NOTE: The fireplace should be run 3 to 4 hours on the initial start-up. Turn it off and let it cool completely. Remove and clean the glass. Replace the glass and run the fireplace for an additional 8 hours. This will help to cure the products used in the paint and logs.

During this break-in period it is recommended that some windows in the house be opened for air circulation. This will help avoid setting off smoke detectors, and help eliminate any odors associated with the fireplace’s initial burning.

You’ve reviewed all safety warnings, you’ve checked the fireplace for gas leaks, you know the vent system is unobstructed, and you’ve checked for faulty components. Now you’re ready to light the fireplace.

!WARNING: PLEASE REFER TO THE USER’S MANUAL FOR ALL CAUTIONS, SAFETY, AND

WARNING INFORMATION PERTAINING TO THE LIGHTING AND OPERATION OF THE FIRE- PLACE.

LEAVE THIS INSTALLATION MANUAL WITH THE APPLIANCE FOR FUTURE REFERENCE.
