Step 3 Installing The Vent System; Vent System Approvals - Heat-N-Glo Grand-50-D Manual

Step 3. Installing the Vent System
A. Vent System Approvals
This model is approved to use D-series direct vent compo-
nents and terminations (Figures 4 and 5). Approved vent
system components are labeled for identification. This pipe
is tested and listed as an approved component of the fire-
place. The pipe is tested to be run inside an enclosed wall.
There is no requirement for inspection openings at each
joint within the wall. There is no required pitch for horizontal
vent runs. NO OTHER VENTING SYSTEMS OR COMPO-
NENTS MAY BE USED.
Detailed installation instructions are included with each vent
termination kit and should be used in conjunction with this
Installers Guide.
The flame and ember appearance may vary based on the type
of fuel burned and the venting configuration used.

Identifying Vent Components
The vent systems installed on this gas fireplace may in-
clude one, two or three 90° elbow assemblies. The relation-
ships of vertical rise to horizontal run in vent configurations
using 90° elbows MUST BE strictly adhered to. The rise to
run relationships are shown in the venting drawings and
tables. Refer to the diagrams on the next several pages.
NOTE: Two 45° elbows may be used in place of one
90° elbow. Rise to run ratios in the vent system must
be followed if 45° elbows are used.
