WATER CONNECTION INSTALLATION
Gather the loose items that were shipped with the
heater. They will be as shown below:
The components should be assembled onto the
inlet/outlet header of the unit as shown below.
Once all components are in place and installed prop-
erly, the water connections will appear as shown
below:
UNITHERM GOVERNOR OPERATION
CAUTION:
The patented Unitherm Governor is a thermostatic
mixing valve specifically designed to maintain con-
stant heater internal temperature between 105° and
115°F despite continually changing flow rates from
the filter and changing pool temperatures. This nar-
row range is needed to prevent damaging condensa-
tion on the burners which will occur if the heater runs
for any length of time below 100°F. It is also needed
to inhibit scale formation in the tubes by maintaining
temperatures well below accelerated scaling temper-
atures.

The heater must be located so that any water leaks will
not damage the structure of adjacent area. High tem-
perature 2" plastic pipe (CPVC) may be threaded
directly into the header flanges. This is not the same
as the Schedule 80 PVC pipe which is also gray. PVC
may be used immediately after the supplied CPVC
adapters.
DO NOT
use petroleum-based assembly fluids (such
as petroleum jelly or lubricating oil). If assembly lube is
required, use a silicon base such as AquaLube etc.
