4. Repeat steps 1 to 3 for other lag-bolts mounting points. Use a level to ensure C-channel is
horizontal.
5. With C-channel lag-bolts in place and tightened completely, check that roof-sealant has made a
good seal. Apply additional sealant if necessary.
6. Measure down 48” (1220 mm), center to center, to fix lower C-channel position. Follow same
procedure to secure and seal lower C-channel.
Process for installation on a standing seam metal roof is very similar. EnerWorks Metal Roof Add-on Kit
contains additional nylon spacers to raise C-channel farther from roof surface, allowing clearance of
raised seams. Longer (6”) lag-bolts are also included to ensure a solid anchor.
Metal roofs can be extremely slippery, especially if wet. Do not get on metal roofs if they are covered in
dew or if it is raining. Use extra caution when working on metal roofs.
Before solar collectors can be installed, line-set (with control wire) must be pushed/pulled through roof-
penetration. Flashing boot must be installed to seal penetration. Note in Fig. 5.4.1, insulated lines and
control wire are wrapped with tape to protect insulation from ripping as it is pulled through rough-
edged penetration.
