device at top. Collectors mounted in “landscape” orientation are not covered by warranty as
stagnation-control device will not operate as designed.
For convective cooling to occur, a minimum collector-angle of 14° (3:12 pitch) is
necessary. Warranty is not valid for collectors installed flat or at an angle less than 14°(3:12
pitch).
Depending on number of collectors or on installation conditions, it may be necessary to change a left-
collector to a right-collector or vice-versa. This is accomplished by swapping stagnation control device
and intake grill. If this is not necessary, proceed to temperature sensor installation.
Swapping stagnation-control device and grill may be accomplished by laying collector, glass down,
on a soft and padded surface, such as a blanket or large piece of cardboard. Be extremely careful as
broken glass is not covered by warranty. Ensure surface is flat and s m o o t h . I t m a y a l s o b e
accomplished with collector standing on long side with connections up. It should not be attempted in
rain.
1. Remove and set aside five screws that hold grill in place at bottom of collector (Fig. 6.1.2). Center
screw is self-drilling and different from others (see insert in Fig. 6.1.2). Carefully remove grill by first
lifting perforated section and then by gently pulling grill away from aluminum-covered back
insulation.
2. Remove and set aside ten screws that hold stagnation-control device in place at top of collector. Six
long self-drilling screws hold the mechanism to aluminum backing. Four self-threading screws
hold white plastic hinge blocks (two screws per block) to frame at each end of it (Fig. 6.1.3).
Note function and orientation of plastic hinge blocks and remove them.
Warranty is only valid for collectors mounted in “portrait” orientation with stagnation-control
