Hearth and Home Technologies SL-550TRSI-AUE manual Connecting The Gas Supply, Gas Supply Line

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

•Locate and mark the flue centerpoint on the under- side 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 (25mm) clearance from the vertical flue pipe to com- bustible materials.

•Mark the roof hole accordingly.

•Cover the opening of the installed flue 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 flue sections up through the roof hole and up past the roof line until you reach the appropriate distance above the roof.

CAUTION: FOLLOW THE REQUIREMENTS OF THE AGA GAS INSTALLATION CODE FOR MINIMUM HEIGHT REQUIREMENTS ABOVE THE ROOF.

To seal the roof hole, and to divert rain and snow from the flue system:

•Attach a flashing to the roof using nails, and use a non-hardening mastic around the edges of the flash- ing 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 flue pipe and rotate the pipe clockwise 1/4 turn.

After the gas pipe installation is complete, check carefully all gas connections for leaks with a commercially-available, non-corrosive leak check solution. Be sure to rinse off all leak check solution following testing. DO NOT USE AN OPEN FLAME.
