INSTALLING FLASHING AND

STORM COLLAR

Remove the nails from the shingles above and to the sides of the chimney. Place the fl ashing over the chimney pipe and slide under- neath the sides and upper edge of the shingles. Ensure that the chim- ney pipe is properly centered within the fl ashing, giving a 3/4" margin all around. Fasten to the roof on the top and sides. DO NOT NAIL through the lower portion of the fl ashing. Make weather-tight by seal- ing with caulking. Where possible, cover the sides and top edges of the fl ashing with roofing material. Apply waterproof caulking, provided with the fl ashing, around the chimney, 1" above the top of the flashing and push the storm collar down into the caulking. Insert a rain cap onto the top of the last chimney section.

IF THE CHIMNEY IS

UNLINED:

A stainless steel liner listed to either

S t a n d a r d U L C - S640M, ULC-S639 in Canada or UL-1777 in the USA: Liners for New Masonry Chimneys, may be used to connect the fireplace to the chimney. The liner must be continuous from the fireplace to the chimney cap and be installed only per manufacturers i n s t r u c t i o n s . Figure 19. In both cases, the chimney

structure must be supported by angle iron anchored into the masonry walls. Figures 19 & 20. The allowable masonry used in chimney construction is 3-1/2" brick, solidly mortared and fully encasing the fl ue. Ensure there are no leaks.

In no case is the masonry enclosure to be supported by the NZ-26 fi replace. Allow a 1" (one inch) air cavity for expansion.
