NOTES:
- Sleeve extension must be same material and gauge as factory sleeve.
- The inside dimensions of the sleeve extension must be the same dimensions as the outside dimensions of the factory sleeve.
- Sleeve extension must overlap the factory sleeve a minimum of 1″ (25).
- All four sides of the sleeve extension must be attached to the factory sleeve. Attachments must be spaced a maximum of 6″ (152) on center and a maximum of 2″ (51) from corners. A minimum of 2 attachments per side (8 per damper) are required. Attach the sleeve extension using 1/2″ (13) long tack or spot welds, #10 sheet metal screws, 1/4″ (6.35) dia. bolts and nuts or 3/16″ (5) steel pop rivets.
- Products with a smoke leakage rating require that the joint between the two sleeves be sealed with a continuous 1/8″ (3) bead of Dow Corning 732, G.E. RTV108, Boss 310 or 315RTV silicone sealant.
- Sleeve extensions can be made to either end of the factory sleeve. However, the sleeve cannot extend beyond the fire partition more than 6″ (152) on either side or 16″ (406) on one side if equipped with an actuator or integral access door.
- The joint created by the factory sleeve and sleeve extension cannot be in the plane of the fire rated barrier.
