MANIFOLD
With the bypass hose re11]?ved, there remain two connecting
points A and B for hoses to run to and from the water heater.
These connections assure '" fiowofhot water through the
heater at all times but do not restrict the engine's cooling
water.
, Connection point A on the Flow Control housing should
connect to the lower of the two connections on the water
heater
while the upper connection on the heater returns to
connection B, nearest the heat exchanger_
Hoses should rise continuously from their low point at the
heater to the engine so that trapped air will rise naturally
from the heater to the engine. If trapped air is able to rise to
the heater, then an air bleed petcock must be installed at the
higher fitring on the heater for bleeding air while filling llie
system. Avoid loops in the hose runs which will trap air.
