Please Note: A major cause of chimney related fires is due to a failure to maintain required clearances (air space) to combustible materials.
- Page 3 U31-10 Gas Insert Venting THE APPLIANCE MUST NOT BE CONNECTED TO A CHIM- NEY FLUE SERVING A SEPARATE SOLID FUEL BURNING APPLIANCE. This appliance is designed to attach to a 4” diameter type B-Vent or listed gas fuel type vent liner running the full length of the chimney. A minimum flue height of 12 feet is recommended. B-Vent must be supported by a vent support - supplied by vent manufacturer. See chart on this page for minimum distances from roof. The FPI Insert incorporates its own internal draft hood, so no additional external draft hood is required. Periodically check that the vent is unrestricted and an adequate draft is present when the unit is in operation. (See page 8 for spillage test.) Before installing vent system ensure that the damper plate is open and secure to prevent the damper plate from falling down and crushing the liner. WARNING: Operation of this appliance when not connected to a properly installed and maintained venting system or tampering with the blocked vent shutoff system can result in carbon monoxide (CO) poisoning and possible death.
