TYPICAL CHIMNEY INSTALLATION
d. Wrap the Storm Collar around the chimney above the flashing. Secure the ends together loosely with the nuts
and bolts supplied. Slide the collar down the chimney until it contacts the flashing guides and/or draw band.
Tighten the nuts and bolts and seal the Storm Collar to the chimney with suitable waterproof non-combustible
mastic. After installation check to ensure that the flashing guides maintain an air space between the Storm
Collar and the cone flashing.
WARNING: Do not block the air space between the storm collar and the cone flashing.
e. The flashing and storm collar should be painted to match the roof shingles. This will extend its life and improve
the appearance. Clean and paint with suitable painting products.
f. Continue adding chimney lengths until the proper height is achieved. Install a rain cap (standard or deluxe
model) and lock it in place by turning clockwise until tight.
g. If the chimney extends more than 5’ (1600mm) above the roof deck, roof guys are required. GSW Model J6RG
roof guy kit is used this application. The draw band must be clamped around the chimney and the two legs
bolted to the roof. Seal the roof with a suitable waterproof mastic. Tighten the two leg clamps to fix the position
of the telescopic legs.
