Horizontal Termination Installations
• The 530 heater may be installed using components from a variety of
manufacturers listed on pages 36–37.
• Allowable vent con
fi
gurations and clearances for the 530 heater are listed in this
manual and apply for all vent components listed on pages 36–37. For details of
component installation, follow instructions packaged with each component.
• The 530 heater is supplied with a smooth 4-by-6-5/8-inch co-axial collar
intended to accept the Valor 551DVK Vent Termination with pipe attached. All
other applications will require an 817VAK Vent Adapter to convert the collar to a
twist-lock type collar. All other manufacturers’ components listed (including Valor
551DVK) have designed their components to
fi
t this twist-lock type collar.
• Do not mix components from different manufacturers.
• Do not cut pipe lengths, except the 551DVK which may be cut to desired length.
Use adjustable lengths otherwise.
Fix the Vent Unit or 817VAK to
Appliance
• Fit the vent unit or 817VAK over the
inlet and outlet collars of the appliance,
pushing on
fi
rmly. If using the 551DVK,
ensure that the end of the pipe is cut
cleanly and square. Rotate the pipe to
ensure that the seam will pass through
notch in the wall plates and that the drain
hole is at the bottom.
• Drill through the outer tube and the
appliance collar with no. 6 screws.
Make
sure the drill does not penetrate the inner
pipe
.
• Secure the vent unit or 817VAK to the
outer collar with two no. 6 thread-cutting
screws supplied.
Through the wall details
• If the wall has combustible material,
appropriate insulation shielding or wall
thimble must be used speci
fi
c to the
manufacturer of the venting. In any case,
a minimum of 10 x 10 inches square
or 10-inch diameter hole is required. If
the wall is totally non-combustible (e.g.
masonry block or concrete) mark for a
7-inch circular hole. In both cases, the
center of the hole should line up with the
center line of the horizontal vent.
• See
Horizontal Termination Locations
section for allowable vent terminal
locations.
• Avoid structural elements when locating
the hole through the wall.

Important Installer Notice – Weather Sealing
& Vapor Barriers
It is the installer’s responsibility to ensure that vent installations
through exterior walls are caulked and weatherproofed in such a
manner as to:
• Prevent rain water from entering the wall from the weather side
by adequately caulking the outer vent plate to the exterior wall
surface.
• Prevent moisture inside the home from penetrating into the wall
structure by ensuring the inside wall plate is adequately sealed to
the inside vapor barrier.
• Prevent rain water and moisture from entering the walls by
sealing the joints between the outer vent tube and the inner and
outer wall plates.
We recommend the use of a high quality polyurethane sealant.
