7.3 Leaf-Guard Installation
Leaf-guard is included with three- and four-collector Appliances to protect and shade insulated line-set.
Leaf-guard for one- and two-collector Appliances is optional and is of benefit to prevent leaves and
debris from gathering around and beneath collectors. Leaf-guard includes thin lengths of perforated,
painted, galvanized steel and triangular end-caps. Perforations ensure proper functioning of patented
stagnation control device. Each section of leaf-guard is slightly longer than collector is wide.
1. Insert lower edge of leaf-guard section into side-wall groove at top of collector. Align side edge of
leaf-guard section with outer side of collector or with side-flashing. Leaf-guard sections are
overlapped to ensure edges are flush with outer collector side-walls.
2. Secure leaf-guard to roof with included roofing screws.
3. Insert triangular caps into left and right leaf-guard ends. Secure end caps to roof with included
roofing screws (Fig. 7.3.1).
4. Secure end-caps to leaf-guard sections and secure sections to each other at overlaps with self-
drilling screws.
5. Bend center-flashing down to leaf-guard and secure with self-drilling screws if applicable
(Fig. 7.3.1).
