manifold by twisting and pushing in to the manifold as straight as possible. Use controlled, firm pressure. The tubes
will suddenly slide easily once fully pushed though the manifold gasket. Use extreme caution not to insert too far so
as to bump into the opposite side of the manifold or a glass tube on the other side causing glass to shatter. Put a
small piece of pex or other soft material from above or below another hole through the manifold as you install to
keep the tubes from hitting each other is a good idea.
•
Slip the plastic end protector over the bottom of the tube and while twisting, pull to seat in place on the metal side
frame tube holder.
•
NOTE! When installing fittings on the manifold you must hold on to the manifold ports with a wrench or the welds
will break.
•
All water lines for the solar system are required to be a minimum 1” for proper flow and the best thermo-siphoning
performance and must be super insulated. Heat tape will be necessary to install BEFORE you super insulate. Use a
heat tape that has a thermostat so it will only turn on if it gets cold to save energy.
This is required to protect your
system!
If a line freezes, thermo-siphoning cannot take place and boiling can occur, possibly pushing out and
breaking a glass tube or a line can break, draining the system which can also result in damage to your SM-H60 or
your boiler.
•
Install a 1” water feed line from the bottom of the water jacket drain outlet at a downward angle from the boiler to
the bottom of the solar manifold so the cooler water can fall. Use a T so you can still drain the water jacket if
needed. Install a 1” line from the top of the manifold on a straight upward angle to an extra port on the boiler so the
heated water will rise (thermo-siphoning) and so air cannot get trapped.
Installing on boilers with no upper solar return port
**You may only do this if the boiler return line from the house is higher than the top of the solar manifold otherwise
a solar return port must be installed by cutting and welding one in to the water jacket.**
•
Put a 1” T coming off the return port with the boiler return line landed on the ‘T’ pointing down. Install a 1” line
from the solar heater into the end of the tee with the following setup: For the solar line in the end of the T use a 1”
male thread to 1” pex fitting. Solder into the inside of the male thread a copper ¾” x ½” coupling and then solder in
that a ½” copper pipe that will extend to a ½” short of coming out of the nipple that is welded to the boiler. With
this system the water flowing past the ½” copper tube from the boiler return line will move the water in the solar
system by siphon. This setup will not affect summer use when not firing your boiler and the boiler circulation pump
only runs intermittently.
For attaching to boilers where the boiler return port is 1-1/4”, use a 1-1/4” T with bushings to reduce to 1”. Solder
into the 1” pex adapter a ¾” copper coupling with a ¾” copper pipe that will extend to exactly ½” short of coming
out of the nipple that is welded to the boiler.
