APPENDIX B
Marking markers, cutting out the opening and fixing the hood collar
• Determine the path of the steam vent between the hood and where it will pass through the roof.
• Mark the centre of the vent pipe on the hood with a marker.
• Centre the supplied hood pipe collar (Illustration 1 No. 7) on this mark, then mark the opening to be cut in the
hood.
- Cut the hood opening.
- To do so, you will need a jigsaw, manual or electric sheet metal shears, and a grinder.
• Position the hood pipe collar on the opening and secure it with rivets or self-tapping screws.
Before beginning the installation
• Screws and rivets.
- Use rivets or self-tapping screws to connect the chimney sections. Rivets and screws are not included.
• Thoroughly inspect all the sections of your vent.
• First section to be installed.
- If your evaporator is equipped with a preheater, the first section to be installed over the rear
hood has a flue damper already installed in the section (as shown in Illustration 1 No. 1).
o If the evaporator does not have a preheater, you must install a single section (as shown in Illustration 1 No. 4).
Installing your steam vent
• Install the first section of your vent on the evaporator hood pipe collar (Illustration 1 No. 7). Place the corrugated
end of the pipe against the hood pipe collar downward, then the plain end upward.
• Continue installing single vent sections until one section passes through the roof.
• Then install the roof flashing (Illustration 1 No. 3).
- Make sure the flashing is securely fastened to the roof.
- Ensure perfect waterproofing of the seal between the flashing and the roof using silicone
sealing compound.
• Install the flashing tie over the vent (Illustration 1 No. 6).
- Leave a 1 in. (2.54 cm) clearance between the top of the flashing and the base of the rain tie.
• Continue the installation with a single vent section above the roof (Illustration 1 No. 4). Typically, the installation
will allow 3 to 4 ft. (91.44 cm to 1.22 m) above the roof.
• Install the rain cap (Illustration 1 No. 5).
- If you are using a rope operated rain cap, install the actuator cables from the cap.
• Check and adjust the alignment of the steam vent with the part under the roof.
