Amazon Heater Pipes Layout

[red122]

There are two pipe fittings on the heater and two on the heater control that goes through the bulkhead plus one on the end of the pipe from the water pipe and one on the union into the back of the head.
Can anyone confirm please which way to link these up ? In other words which end goes to which other one ?

Thanks in advance

TOP outlet on heater valve goes to TOP inlet on heater box.

BOTTOM inlet on heater valves connects up to the outlet on back of engine nearest the manifold.

BOTTOM outlet on heater box connects up to inlet on back of engine on battery side of engine.

Thanks very much for your help ,just to be clear the bottom inlet on the heater valve connects to the L shaped union in the back of the head ?

Difficult to explain!!!

The one off the bottom of the heater control valve connects to the metal pipe that runs under the manifold and connects up to the water pump

The one at the bottom of the heater box connects to the stub at the back of the engine.
