Flue System Approvals and Installation
A. Flue System Approvals
These models are approved to use DVP series direct
flue pipe components and terminations (see Figures 5
and 8). Approved flue system components are labeled
for identification. This pipe is tested and listed as an
approved component of the heater. The pipe is tested
to be run inside an enclosed wall. There is no require-
ment for inspection openings at each joint within the
wall. There is no required pitch for horizontal flue runs.
NO OTHER FLUEING SYSTEMS OR COMPONENTS
MAY BE USED.
Detailed installation instructions are included with each
flue 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 flueing configuration used.

Identifying Flue Components
The flue systems installed on this gas heater may
include one, two, or three 90° elbow assemblies. The
relationships of vertical rise to horizontal run in flue
configurations using 90° elbows MUST BE strictly
adhered to. The rise to run relationships are shown in
the flueing drawings and tables. Refer to the diagrams
on the next several pages.
This model has a 45° elbow built into it. It may be posi-
tioned to flue either horizontal or vertical. Depending on
the installation, decide which direction the elbow should
be facing. Remove the 8 screws from the corner cover
plate. Position the 45º elbow as desired and replace
the corner cover plate with the 8 screws.
