Pressure-Temperature Relief Valve (Tankless Water Heater); Furnace - Propane Gas - Winnebago 2015 Viva! Owner's Manual

Note: Use caution not to increase the Dial too
much which could cause the Hot Water
Temperature to rise to the point the
Water Heater "limits" and turns OFF
the flame. Flame shut off is
approximately 131 degrees F.
Further Information
See the Water Heater manufacturer's
operation manual provided in your InfoCase for

and maintenance information.
PRESSURE-TEMPERATURE
RELIEF VALVE (TANKLESS
WATER HEATER)
On occasion, water may be seen seeping from
the water heater pressure temperature relief
valve. This is no cause for repair or replacement
of the valve.
Water Heater Exterior Service Access
-Typical View
Normally there is an air gap at the top of the
heat exchanger, which acts as a pressure buffer.
In time, however, heated water may expand and
fill this air gap, causing a slight increase in water
pressure. This may cause the P-T valve to "weep"
until the air gap is manually replaced.
APPLIANCES AND SYSTEMS
C AUT I ON
Hot water can escape from tank causing
injury. Operate this valve only when the
tank water is cold.
To Replace the Air Gap:
1. Turn off the Water Heater switch and
incoming water supply (city water and/or
demand pump).
2. Open a faucet in the motorhome to relieve
water pressure.
3. Pull the handle of the P-T valve straight out
and allow water to flow until it stops.
• Lift handle straight out to open P-T valve
when water heater is cold.

4. Let the handle of the P-T valve snap shut.
