1.3 Flue Sytem 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 6).
Approved flue system components are labeled for identifi-
cation. This pipe is tested and listed as an approved com-
ponent of the heater. The pipe is tested to be run inside an
enclosed wall. There is no requirement for inspection open-
ings 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.

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.
