TIP: Custom flare fitting union is of custom length to allow flashing to slide between
collectors. No custom-length fitting is present at lower connections. To ensure collectors are square and not
“toed in or out” at bottom, temporarily slide center-flashing between collectors before securing second
collector. This will allow for easy installation of center-flashing when appliance commissioning is complete.
6. Secure second collector with supplied bolts, washers and twirl nuts.
Maximum torque of 9
ft·lb or 12.2 N·m.
7. Follow similar procedure for installing third and fourth collectors if applicable. Three
collector appliances do not have custom flare fitting union between all collectors. Use center-
flashing to ensure appropriate spacing if custom flare fitting unions are not present.
EnerWorks Solar Water Heating Appliances are sized with one, two, three or four solar collectors. See
EnerWorks Site Evaluation, Appliance Selection and Sizing manual to determine correct size.
Connection procedure:
1. Install collector immediately next to roof-
penetration such that line-set can be covered
by side-flashing (Fig. 6.4.1).
2. C a r e f u l l y b e n d l i n e - s e t t o c o l l e c t o r
connections (if necessary, use a proper tube-
bender for tight bends).
3. Cut off excess tube with a proper tube-cutter.
Use a light feed to minimize burr, work-
h a r d e n i n g a n d c o m p r e s s i o n o f t u b e .
Remove burr with de-burr or ream tool.
