Metal roofs
To fit the solar water heater onto a metal roof, locate the nearest point of a purlin where the top
feet of the frame needs to be installed. Secure the top feet of the frame on the purlin. If no purlin is
available, support the inside of the metal roof sufficient to be able to carry the weight of the solar
water heater. Use the correct roof mounting screws and matching sealing washers to secure the
frame to the roof.

Installation
