25/08/2016· The purpose of a heater control valve is to control the flow of engine coolant to the heater core, located within the passenger compartment. When the heater or defroster is turned on, warm engine coolant passes through the heater core. Here a fan forces air across the surface of the heater core and then into the passenger compartment where the warm air is felt.
recommends the installation of a check valve on the cold water inlet. Seal all pipe fittings with Teflon tape or Loctite thread sealant. Thermal Expansion: When a Water Heater is installed in a closed water supply system, such as one having a back flow preventer in the cold water supply, means shall be provided to control thermal expansion. 2.
No check valve may be installed in the supply line to the booster. All shut off valves must be gate or ball valves not globe valves. The brass pressure reducing valve with built in bypass is adjustable from 25 to 75 psi. To minimize heat loss and maximize efficiency, hot water piping should be insulated.

The heater control valve opens and closes to allow warm coolant to flow through the heater core. Air passing through the heater core creates hot air in your vents. It sits between the water pump heater hose and the heater core. The heater control valve is found in front of the firewall of the vehicle. It may be controlled either by vacuum ...

Water Heater Troubleshooting.pdf P a g e 7 Version: 1.3 June 13, 2015 110V Wiring Diagram This diagram shows the electric flow on the back of the water heater, through the secondary switch, to the Hi Limit/ECO, to the Thermostat, and then to the electric element. Note that the black wire is hot, and the white wire goes to neutral.
On other trailer configurations, the bypass valve will usually be inside, near water connections to the water heater, accessible by way of a drawer or panel. Second, open a faucet and check that water flows equally when the faucet is full to Cold and full to Hot settings. CAUTION
