MUST BE USED. FOLLOW INSTRUCTIONS INCLUDED.
CAUTION: This gas appliance must not be connected to a chimney flue serving another type of appliance.
1. If your vent system application is 8' or less from the top of the fireplace and doesn’t require an extension kit, proceed to step #7.
2. If your vent system application will require one or more extension kits (part #846), proceed with the following steps. Each #846
extension kit contains enough 5" and 8" flexible aluminum to extend the chimney an additional 6'.
3. Gently stretch the 5" & 8" flexible aluminum pipes on the termination kit (#844 or #845) and on each extension kit, if used, the
length required so when all the sections are connected together, the vent system length for your installation is attained.
IMPORTANT: DO NOT STRETCH THE EXTENSION KIT BEYOND 6'. DO NOT STRETCH BEYOND WHAT IS REQUIRED - IT IS VERY
DIFFICULT TO RECOMPRESS THE FLEX PIPES ONCE STRETCHED.
4. Using your extension kit pieces, place a bead of sealant outside the 5" flex pipe collar (C) - the end with the EXTERNAL lip - and
slide it inside the 5" pipe on top of the fireplace (D). Secure with 3 evenly spaced screws.
5. Place a bead of sealant inside the 8" flex pipe collar (E) - the end with the INTERNAL lip - and slide it over the 8" pipe on top of the
