Pressure Relief Valve; Thermostat And Manual Reset - Jayco COVE 2002 Owner's Manual

PRESSURE RELIEF VALVE

The temperature and pressure relief valve (Fig. 5-2) is designed to open if the temperature of the
water within the heater reaches 210°F, or if the water pressure in the heater reaches 150 pounds.
park trailer water systems are closed systems and during the water heating cycle the pressure
build-up in the water system will reach 150 pounds. When this pressure is reached, the pressure
relief valve will open and water will drip from the valve. This dripping will continue until the
pressure is reduced to below 150 pounds, and the valve closes. This condition is normal and does
not indicate a defective relief valve.
I
WARNING: Do not place a valve between the relief valve and the tank. Do not plug
the relief valve under any circumstances.
