Superior Fireplaces DRL4543TEN Installation And Operation Instruction Manual page 14

INSTALLATION PLANNING
There are two basic types of direct-vent installation:
• Horizontal Termination
• Vertical Termination
Installing the Horizontal Termination Vent System
These instructions should be used as a guideline and do not supersede local codes in any way. Install venting according to local codes,
these instructions, the current National Fuel Gas Code (ANSI-Z223.1) in the USA or the current standards of CAN/CGA-B149.1 in Canada.
Ensure clearances are in accordance with local installation codes and the requirements of the gas supplier.
Horizontal vent systems terminate through an outside wall. Building Codes limit or prohibit terminating in specific areas (Figure 7, Page 12).

1. Analyze the vent route and determine the number of vent
sections and elbows required—Plan the venting so that a
joint does not occur in the ceiling or roof joists. Maintain
the minimum clearances for combustibles (Page 9).
2. Frame the exterior wall opening—Locate the center of the
vent outlet on the exterior wall. Cut and/ or frame an open-
ing, 10 1/2 x 12 1/8" (267 x 308 mm) inside dimensions,
about this center.
3. Frame the ceiling opening—If the vertical route is to pen-
etrate a ceiling, use plumb line to locate the center above
the fireplace. Cut and/or frame an opening, 10 1/2 x 10
1/2" (267 x 267 mm) inside dimensions, about this center
(Figure 17, Page 19).
4. Attach the vent components to the fireplace—See Con-
necting the vent pipe on Page 17.
5. Attach the vent components to each other—See Connecting
the vent pipe on Page 17.
6. Install the firestop/spacer at the ceiling—When using Rigid
Pipe, use SV4.5VF firestop/spacer at ceiling joists. If there
is living space above the ceiling level, the firestop/spacer
must be installed on the bottom side of the ceiling.

be installed on the top side of the joist. Route the vent sec-
tions through the framed opening and secure the firestop/
spacer with 8d nails or other appropriate fasteners at each
corner. Maintain 1" (26 mm) clearance to combustibles,
framing members, and attic or ceiling insulation when run-
ning vertical chimney sections.

and secure to the framing members with nails or screws
(Figure 8).
tal/inclined run, install SV4.5E45 or SV4.5E90 elbows in
the same manner as the straight vent sections. The elbows
feature a twist section to allow them to be routed about
the center axis of their initial collar section to align with
the required direction of the next vent run element. Twist
elbow sections in a clockwise direction only so as to avoid
the possibility of unlocking any of the previously connected
vent sections (Figure 13, Page 17).
