Jon,

your '93 should have one set of valves (the lowest two valves on the side of the engine) are for the front heater. There is an inline booster pump for this circuit which is activated when the temperature control lever for the dash heat is turned about 1/2" off of cold. The valve that is the outgoing line is on the bottom. The other two valves are higher up with the top most valve actually on the front on the engine. Those lines circulate water to the rear bedroom heater and the water heater.

Also does your coach have the primus system?

Just sharing some info,

Sean
