U37 Regency ULTIMATE Rear Vent Direct Vent Freestanding Gas Heater

Below Grade Snorkel Installation
If the Snorkel Termination must be in-
stalled below grade, i.e. basement ap-
plication, proper drainage must be pro-
vided to prevent water from entering
the Snorkel Termination. Refer to Dura-
Vent Installation instructions for de-
tails.. Do not attempt to enclose the
Snorkel within the wall, or any other
type of enclosure.

4) Install wall penetration heat shield in the

center of the 9-1/2" round hole and attach
with wood screws. The four wood screws
provided should be replaced with appropri-
ate fasteners for stucco, brick, concrete,
or other types of sidings. Dia. 3.

5) If installing termination on a siding covered

wall, a vinyl siding standoff or furring strips
must be used to ensure that the termination
is not recessed into the siding.  Dia. 3.

6) Take the Riser Vent terminal and separate

the Backing Plate from the Riser Vent Front
by removing 8 screws as shown in dia-
gram 4.

7) Install the Backing Plate into the wall pene-

tration heat shield and attach using 4
screws. Dia. 4.

8) Connect all pipe sections to unit and install

into wall:

a) Measure pipe length required and cut to

length. Hint: use the cut end of the 6-5/
8" dia. outer pipe at the vent terminal
end.

b) Push the pipe sections completely to-

gether, the minimum pipe overlap is
1-1/4".  Secure all outer pipe joints by
using at least two screws. Locate the
screws at the bottom of the pipe so that
the screw heads are hidden on the final
installation. Apply sealant "Mill-Pac" to
inner pipe and high temp silicone seal-
ant or "Mill-Pac" to outer pipe on every
joint.

c) Before connecting the vent pipe to the

vent termination, slide the black deco-
rative wall thimble cover over the vent
pipe, then slide the Wall Penetration
Heat Shield (Part # 946-202) over the
vent pipe. Dia. 3.

d) Slide the appliance and vent assembly

towards the wall carefully inserting the
vent pipe into the riser vent terminal
assembly. It is important that the vent
pipe extends into the Riser Vent Back-
ing Plate a sufficient distance so as to
result in a minimum pipe overlap of
1-1/4 inches. Secure the connection
between the vent pipe and the vent cap
by attaching the two sheet metal strips
extending from the Riser Vent Backing
Plate into the outer wall of the vent pipe.

Use two aluminum screws provided to
connect the strips to the pipe section.
Bend any remaining portion of the sheet
metal strip back towards the vent cap
and cut off any excess, it will be con-
cealed by the decorative wall thimble
cover. See diagram 5.

8) Slide the decorative wall thimble up to the

wall surface being careful not to scratch
the paint.  See diagram 5.

9) Back outside: Apply sealant to the 4" inner

flue and slide the Riser Vent Front into the
Backing Plate and fasten with 8 screws.

10) Seal around the outer edge of the Riser Vent

Backing Plate.
