Vertical Vent Installation
Using Flex Bends
Use roof support and rigid pipe at roof level. Flex pipe is not permitted within roof support.
When penetrating the roof a rigid galvanized pipe must be used. Attach flex pipe to the rigid pipe with high temperature
sealant, secure with four screws assuring the flex pipe and rigid pipe are secured. Attach rigid pipe to termination with
sealant and screw with 4 sheet metal screws. The Inner flex pipe must be secured with 4 screws which must penetrate
both the flex pipe and inner section of termination.
Attach 7” rigid pipe to 7” termination with sealant and screw with 4
sheet metal screws.
Vertical termination clearance is 18" [45.7cm] above the roof, measured from highest point of exit on the roof line.
Support vertical pipes to maintain minimum of one inch or greater clearances to combustibles.
Roof Flashing
Ensure that you have the proper roof flashing by checking your roof pitch using a level and two rulers, or by using a roof
pitch card.
Slide a Roof Flashing suitable to your roof slope over the vent. Place the edge of the flashing plate that will be on the
higher part of the roof slope under the shingles. Both the sides and the lower edge lay on top of the shingles.
NOTE: At the top edge of the flashing plate, lift the shingles and nail the plate to the roof deck, then cement the
shingles to the plate with a suitable waterproof mastic.
Ensure that the chimney is plumb. Square up the flashing plate and nail in place to the roof deck. Use 12 nails with
neoprene washers or cover the heads with a suitable waterproof mastic. Wrap the storm collar around the vent above the
flashing. Secure the ends together loosely with nut and bolt supplied. Slide the collar down the vent until it comes in
contact with the flashing. Tighten the bolt and seal the Storm Collar to the vent with a suitable waterproof non-combustible
mastic.
The flashing and storm collar should be painted to match the roof shingles. This will extend its life and improve the
appearance. Clean, prime and paint with suitable painting products.
