Install Instructions

3
Type B Gas Vent - 3" to 12" Diameter
Installation Instructions
Installation of vent pipe in the RSA support
• Place a supporting collar in the groove at the bottom
end of any standard pipe just above the locking ring.
Tighten the screw so that the collar is firmly
clamped into position in the groove. The pipe is
now assembled properly to fit into the support plate.
(See Figure 4.) This pipe assembly will rest on the
upper side of the support plate and provide the
REQUIRED 1-INCH CLEARANCE FROM
COMBUSTIBLES. The pipe will protrude below the
support for connecting additional pipe from the vent
to the appliance. A maximum of 60 feet of vent can
be installed above the support before resupport is
required.
• Place an RDH draft hood connector on the outlet or
the draft hood of the appliance. The aluminum
portion of the draft hood connector should be
fastened to the appliance collar with sheet metal
screws. The extending aluminum portion can be
readily shaped by hand to fit oval collars.
• Install vertical vent pipe and fittings.

Assembling joints
See Figures 6, 7, and 8
• Use gloves when handling vent parts.
• To assemble joints of pipe and fittings, first make
sure that the lock ring is moved upward sufficiently
to clear the formed tabs. Check the tabs to see
that they are projecting slightly outward from the
pipe so that the upper section will slide down over
the top end of the lower section to which it is being
joined. Look for the word "UP" with the arrow
pointing in the direction of flue-gas flow.
• Slide the top pipe or fitting down over the upper
end of the lower pipe until the projections on the
tabs line up with the groove in the lower pipe. The
joint will naturally come to a stop at this point if it is
placed firmly down over the lower section.
• Using the thumbs and fingers, press the tabs into
position, and slide the lock ring down to lock the
tabs in place.
Installation for Optional Model RGS
Firestop/Gripper Support
• At the desired location, cut a square or circular hole
in the floor at a minimum of 2½ inches larger than
the nominal pipe size, but not greater than 4 inches
larger. See chart below. This will provide the
required 1-INCH CLEARANCE FROM
COMBUSTIBLES.
Nominal Pipe Size 3 4 5 9
Minimum Hole Size 5½ 6½ 7½ 8½
Maximum Hole Size 7 8 9 10
Support Hole Dimensions
(inches)
• Place the support over the hole with the ring down.
• Use an 8-penny nail or self-drilling sheet metal
screw in each corner at least
3
/
8
of an inch from the
edge.
• Pipe should be inserted from below. A maximum of
30 feet of pipe may be installed above the support
before resupport is required. (See Figure 5.)
