Zep System II is in compliance with the structural requirements of the 2006 International Building
Code and ASCE 7-05 based on the configurations and criteria provided in the Certification Letter and ac-
companying tables (go to: www.zepsolar.com/resources.html). These tables define the maximum lev-
eling foot spacing requirements for a range of site-specific variables including Roof Pitch (Figure 4.1A),
Wind Exposure Category (Figure 4.1B), Basic Wind Speed (www.windspeedbyzip.com or refer to your
local jurisdiction), Roof Zone (Figure 4.1C), and Ground Snow Load (www.groundsnowloadbyzip.com
or refer to your local jurisdiction). The tables assume that the Average Building Height is less than
30 feet (Figure 4.1D), Importance Factor is 1.0 (building is not a special occupancy structure such
as a public school or public safety building), and the Topographic Factor is 1.0 (building is not on a
bluff or near the top of a hill). Once you collect the site conditions for your project location, refer to
the tables in the certification letter to determine the maximum allowable spacing between Leveling
Feet. If your site conditions are outside the assumptions above, refer to ASCE 7-05 or contact a
structural engineer for assistance.
An entire Zep array can be interconnected with the use of a single tool. Both the Zep Tool and the Flat
Tool provide means for installing the Interlock, the Leveling Foot, and the Ground Zep. The Flat Tool
provides a low-cost alternative to the Zep Tool and also functions to enable inter-Module removal.
The Zep Tool can receive a T30 Torx bit for adjusting the height of the Leveling Feet.
