1 Shielding for a top exit stove must include a shield insert to protect the area behind the flue collar.

2 Chimney connector heat shields must extend exactly 24” (610 mm) above the flue collar of the stove.

3 All installations venting straight up to a factory built chimney require a 24” (610 mm) diameter or square ceiling heat shield. The ceiling heat shield should be 24 gauge sheet metal or equivalent mounted on 1” (25 mm) non-combustible spacers 1” (25 mm) below ceiling.

4 Chimney connector heat shields must extend to within 1” (25 mm) or less of the ceiling heat shield for installations venting straight up to a factory-built chimney. In top exit installations using an elbow to vent to the rear, the chimney connector must be shielded over the entire vertical length.

5 If a single-wall oval-to-round adaptor is used, a shield must be used to protect combustibles to the rear of the adaptor.
