JAYCO TOWABLE SECTION 8 - PLUMBING SYSTEMS
Consult with the local propane company, your dealer or the water heater
manufacturer for proper derating of the water heater. Change out of the orifice
(derating) should be done by the dealer or a qualified service agency.
NOTE: It is important that once the RV has returned to lower elevation (below
4500 feet) any high altitude deration or other adjustments be reversed for proper
operation of the water heater.
Pressure & temperature relief valve
When cold water is heated in the water heater tank, the water pressure will rise.
For this reason, a pressure and temperature (P&T) relief valve is required for
safety in all water heaters. It is normal for the P&T relief valve to release a small
quantity of water during the heating cycle and does not indicate a defective P&T
relief valve. One way to reduce the frequency of the water weeping or dripping
from the P&T relief valve is to maintain an air pocket at the top of the water heater.
This air pocket will form in the tank by design; however, it will be reduced over
time by the everyday use of your water heater (refer to the manufacturer's
manual); If the weeping persists, consult your dealer or a service agency
authorized by the water heater manufacturer.
