5. Install the Y concentric fitting and pipe assembly through the
structure’s hole.
NOTE
: Do not allow insulation or other materials to accumulate
inside the pipe assembly when installing through the hole.
6. Install the rain cap and small diameter pipe assembly into the
Y concentric fitting and large pipe assembly. Ensure small
diameter pipe is bottomed and cemented in the Y concentric
fitting for #100274637 installations and fastened tightly into
the rubber adapter for #100274638 installations.
7. Secure the assembly to the structure as shown in Figure 41
using field-supplied metal strapping or equivalent support
material.
NOTE : Ensure termination location clearance dimensions are as
shown in Figure 35.
If assembly needs to be extended to allow sidewall thickness
requirement, the two (2) pipes supplied in the kit may be
replaced by using the same diameter, field-supplied SDR-26
PVC (D2241) pipe for 100274637 and standard schedule 40
PVC for 100274638. Do not extend dimension D* more than 60
inches (see Figures 38 and 39).
If assembly depth needs to be reduced, dimension D can be as
short as possible.

NOTE : Instead of cementing the smaller pipe to the rain cap, a
field-supplied stainless steel screw may be used to secure the
two (2) components together when field disassembly is desired
for cleaning (see Figure 40).
When using the alternate screw assembly method, drill a
clearance hole in the rain cap and a pilot hole in the vent pipe
for the screw size being used. Failure to drill adequate holes
may cause cracking of PVC components, allowing combustion
products to be recirculated. Failure to follow this warning could
result in personal injury or death.
Do not operate the appliance with the rain cap removed or
recirculation of combustion products may occur. Water may
also collect inside the larger combustion air pipe and flow to the
burner enclosure. Failure to follow this warning could result in
product damage or improper operation, personal injury, or death.
