Unit Installation With Horizontal Termination - Regency HZ54E Quick Start Manual

Unit Installation with
Horizontal Termination
(Rigid Vent Systems)
A top clearance of 3"(76mm) and side &
bottom clearance of 2"(51mm) must be
maintained; except when passing through
a wall, ceiling, or at the termination where
the use of a firestop or wall thimble reduces
the required clearance to 1-1/2" (38mm).
We recommend framing a 11"(279mm) x
11"(279mm) (inside dimensions) hole to
give structural rigidity for mounting the
termination.
Install the vent system according to the
manufacturer's instructions included with the
components.
1) Set the unit in its desired location. Check to
determine if wall studs or roof rafters are in
the way when the venting system is attached.
If this is the case, you may want to adjust the
location of the unit. Rough in the gas preferably
on the right side of the unit.
2) Direct Vent pipe and fittings are designed with
special twist-lock connections to connect the
venting system to the appliance flue outlet. A
twist-lock appliance adaptor is required.
3) In conjunction with the Simpson Direct Vent Pro
system, install the adaptor after the unit is set
in its desired location. Put a bead of Mill-Pac
inside the outer section of the adapter and on
the inner collar. Slip the adapter over the existing
inner and outer flue collar. Fasten to the outer
collar only with the 3 supplied screws (drilling
pilot holes will make this easier).
4) Level the fireplace and fasten it to the framing
using nails or screws through the top and side
nailing strips.
5) Assemble the desired combination of pipe and
elbows to the appliance adaptor and twist-lock
for a solid connection.

Note: For best results and optimum
performance with each approved
v e n t i n g s y s t e m , i t i s h i g h l y
recommended to apply "Mill-Pac"
sealant (supplied) to every inner pipe
connection. Failure to do so may result
in drafting or performance issues not
covered under warranty.
Horizontal runs of vent must be supported
every 3 feet (0.9 meters). Wall straps are
available for this purpose.
6) Mark the wall for a 11" x 11" (279mm x
279mm) square hole. The center of the square
hole should line up with the center-line of the
horizontal pipe. Cut and frame the 11 inch
(279mm) square hole in the exterior wall where
the vent will be terminated. See diagram 2 for
center line requirements.
If the wall being penetrated is constructed of
non-combustible material, i.e. masonry block
or concrete, an 8" (203mm) diameter hole is
acceptable.
Note:
a) The horizontal run of vent must be level,
or have a 1/4 inch rise for every 1 foot of
run towards the termination. Never allow
the vent to run downward. This could cause
high temperatures and may present the
possibility of a fire.
b) The location of the horizontal vent
termination on an exterior wall must meet all
local and national building codes, and must
not be blocked or obstructed. See "Exterior
Vent Termination Locations" section for more
details.

c) Snorkel Terminations:
For installations requiring a vertical rise on the
exterior of the building, 14-inch and 36-inch
tall Snorkel Terminations are available, as well
as the standard Riser Vent. Follow the same
installation procedures as used for standard
Horizontal Termination. NEVER install the snorkel
upside down.
*As specified in CSA B149.1 Installation
Code. Local codes or regulations may
require different clearances.
Below Grade Snorkel Installation
If the snorkel termination must be installed below
grade, i.e. basement application, proper drainage
must be provided to prevent water from entering
the snorkel termination. See diagram 4. Do not
attempt to enclose the snorkel within the wall or
any other type of enclosure.
7) Ensure that the pipe clearances to combustible
materials are maintained (Diagram 5). Install
the termination cap.
Note: When installing a appliance where
the exterior of the house will be or is
sided with vinyl siding, a vinyl siding
standoff or furring strips must be
used to ensure that the termination
cap is not recessed into the siding. If
there is no siding installed - install the
vinyl siding standoff or furring strips
to the exterior of the home where
the termination cap is to be installed.
Install the cap on the vinyl siding
standoff or furring strips. J-channel
can then be installed around the vinyl
siding standoff, then the siding can
be installed. If vinyl siding is already
installed - line up the vinyl siding
standoff or furring strips on the vinyl
siding where the termination cap is to
be installed, trace out the vinyl siding
standoff or furring strips, then cut
out and remove the vinyl. Install the
standoff to the exterior of the home.
Install the termination cap on the
vinyl siding standoff or furring strips.
The four wood screws provided should be
replaced with appropriate fasteners for stucco,
brick, concrete, or other types of sidings.
8) Before connecting the horizontal run of vent
pipe to the vent termination, slide the Wall
Thimble over the vent pipe. The wall thimble
is required for all horizontal terminations.

9) Slide the appliance and vent assembly towards
the wall carefully inserting the vent pipe into
the vent cap assembly. It is important that the
vent pipe extends into the vent cap sufficient
distance so as to result in a minimum pipe
overlap of 1-1/4 inches (32mm). Secure the
connection between the vent pipe and the vent
cap.
10) Install wall thimble in the center of the 11"
(279mm) square and attach with wood screws
(Diagram 6).
