For Vertical Terminations - To locate the vent and install the vent sections:

• Locate and mark the vent centerpoint on the underside of the roof, and drive a nail through the centerpoint.

• Make the outline of the roof hole around the centerpoint nail.

• The size of the roof hole framing dimensions depend on the pitch of the roof. There MUST BE a 1-inch (25.4 mm) clearance from the vertical vent pipe to combustible materials.

• Mark the roof hole accordingly .

• Cover the opening of the installed vent pipes.

• Cut and frame the roof hole.

• Use framing lumber the same size as the roof rafters and install the frame securely . Flashing anchored to the frame must withstand heavy winds.

• Continue to install concentric vent sections up through the roof hole (for inside vent installations) or up past the roof line until you reach the appropriate distance above the roof (for outside terminations).

NOTE:

WARNING

MAJOR U.S. BUILDING CODES SPECIFY MINIMUM CHIMNEY AND/OR VENT HEIGHT ABOVE THE ROOF TOP. THESE MINIMUM HEIGHTS ARE NECESSARY IN THE INTEREST OF SAFETY. SEE THE FOLLOWING DIAGRAM FOR MINIMUM HEIGHTS, PROVIDED THE TERMINATION CAP IS AT LEAST TWO (2) FEET FROM A VERTICAL W ALL AND 2-FEET BELOW A HORIZONTAL OVERHANG.

This also pertains to vertical vent systems installed on the outside of the building.

Heat & Glo • CFX-CRESCENT • 705-900 Rev . P • 12/07

To seal the roof hole, and to divert rain and snow

from the vent system:

• Attach a flashing to the roof using nails, and use a non-hardening mastic around the edges of the flashing base where it meets the roof.

• Attach a storm collar over the flashing joint to form a water-tight seal. Place non-hardening mastic around the joint, between the storm collar and the vertical pipe.

• Slide the termination cap over the end of the vent pipe and rotate the pipe clockwise 1/4 turn.

Step 11 Before Lighting the Fireplace

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. T ampering 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 .

Step 12 Lighting the Fireplace

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 FIREPLACE.
