7. Slide the decorative wall thimble up the wall surface and attach with
screws provided. Apply the decorative brass or chrome trim kits if
desired.
VERTICAL TERMINATION INSTALLATIONS
1. Insure that the 1-1/4 inch clearances have been maintained to
combustibles when passing through ceilings, walls, roofs, enclosures or
attic rafters.
Do Not pack air gaps with insulation.
Refer to Fig. 7 for
verification of maximum vertical rise of venting system and maximum
horizontal offset limitations.
2. Set the gas appliance in its appropriate location. Use a drop plumb line
from the ceiling to locate exactly the appliance flue exit. Mark the
location where the flue will penetrate the ceiling. Drill a pilot hole at this
location. Now drop a plumb line from the roof to the hole previously
drilled in the ceiling, and mark the spot where the vent will penetrate the
roof. To avoid having to cut any load bearing members of the roof
rafters or ceiling joists, insure they are all out of the path of the venting.
You may wish to offset the venting or relocate the appliance to
accommodate these clearances.
3. To install the Round Support Box / Wall Thimble in a flat ceiling, cut a
10 inch square hole in the ceiling centred on the hole drilled in the
previous step. Frame in the hole from the exterior surface.
4. Assemble the desired lengths of venting pipe and elbows necessary to
reach from the appliance adapter up through the Round Support Box.
Insure that all pipes and elbow connections are in the fully twist locked
position and sealed.
5. Cut a hole in the roof centred on the small drilled hole placed in the roof
during step 2. The hole should be of sufficient size to meet the minimum
requirements for clearances to combustibles. Continue to assemble the
lengths of pipes and elbows necessary to reach from the ceiling support
box up through the roofline. Galvanized pipe and elbows may be used in
the attic as well as above the roofline. The finish of galvanized pipe is
more desirable above the roofline due to its higher corrosion resistance
properties.
6. Slip the flashing over the pipe sections protruding through the roof.
Secure the base of the flashing to the roof with roofing nails. Insure the
