Installation Compliance - Drolet ECO-55 Installation Manual

Here is an example to help you calculate Equivalent
Vent Length. On the following figure the EVL can be
calculated like this:
2 feet of horizontal run (2 X 1' EVL) = 2' of EVL
90° elbow or "Tee" (1 X 5' EVL)
12 feet of vertical run
(12' X 0.5' EVL)
Termination cap
Total EVL
Since the total EVL is less than 15 feet, the re-
commended exhaust venting diameter is 3".

4.3.2 INSTALLATION COMPLIANCE

To determine if your installation is compliant, the
exhaust venting system must end within the grid on
the venting system chart. The previous installation
has 2 feet of horizontal run and 12 feet of vertical
run. It is thus standard since the venting system ends
in the gridded area.
CAUTION
•
Horizontal runs shall not exceed 9 feet.
•
Never exceed 30 feet of evl.
