A. Vent Collar Preparation
Top Vent
Note
: Actual fireplace may look different than the fireplace
shown in this section.
If a straight section of pipe is attached directly to the appli-
ance starting collar, the elbow heat shield is not required.
When installing a 90 degree elbow (SLP90) directly to the
top of the appliance starting collar, the following additional
provisions MUST be followed:
1. The elbow heat shield is not required if combustible
materials, or combustible chases, are installed a mini-
mum of 15 inches above the top of the appliance.
2. If the combustible materials are to be installed be
-
tween 12 to 15 inches above the top of the appliance,
the elbow heat shield is required
. See Figure 6.2.
Top Vent - SLP-FLEX7 Series:
SLP-FLEX7 Series venting requires a minimum initial
vertical requirement (V
1
). Refer to the SLP-FLEX7 Se
-
ries installation instructions for the minimum initial vertical
requirements. The following provisions must be followed:
1. The elbow heat shield is not required if combustible
materials, or combustible chases, are installed a mini-
mum of 6 inches above the top of the elbow. See Fig
-
ure 6.2.
2. If the combustible materials are to be installed between
3 inches and 6 inches above the top of the elbow, the
elbow heat shield is required. See Figure 6.2.
For approved vent configurations, refer to the installation
instructions included with the SLP-FLEX7 collar adapter
(SLP-FLEX7-A).
Refer to Section 10.B for additional clearance to combus
-
tibles requirements.

ELBOW HEAT SHIELD
To Install Elbow Heat Shield:
1. Remove the elbow heat shield from the shipping posi
-
tion, shown in Figure 1, by removing screws.
2. Fasten the shield in place using the four pilot holes.
The shield should be oriented such that the 13 1/8 inch
dimension (longest dimension) is running in the same
direction the elbow is pointing. The shield should be
centered directly above the elbow, and positioned so
that it creates a 1/2 inch airspace between the shield
and the combustible surface. See Figure 6.2
