CONNECTIONS (ASME MODELS)
Heater must be located so that any water leaks will not damage the structure of adjacent area. High temperature 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 colored gray. PVC may be used immediately after the CPVC adapters.

CAUTION: NEVER install PVC directly into header flanges. Use the 2" CPVC adapter supplied loose with the heater.
DO NOT use petroleum base assembly fluids (such as Petroleum Jelly or lubricating oil). If assembly lube is required, use a silicon base such as Amoral etc.
There are two sets of flange gaskets supplied with your heater. Use the appropriate gaskets for all your heater connections. Discard unused set.
GASKET DESIGN #1: Accepts
GASKET DESIGN #2: Accepts 2" copper tube as a slip connection. The flange is threaded for 2" screw in pipe connections. Also used with the 2" CPVC adapters.

UNITHERM GOVERNOR OPERATION
CAUTION:
The patented Unitherm Governor is a thermostatic mixing valve specifically designed to maintain constant heater internal temperature between 105° to 115°F despite continually changing flow rates from the filter and changing pool temperatures. This narrow range is needed to prevent damaging condensation 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 temperatures.
