Pressure-Temperature Relief Valve - Winnebago INTENT Manual

SECTION 4 -
APPLIANCES AND SYSTEMS
• The "DSI FLT" light will glow for about 10-
15 seconds, then it will go out. The "Heater
On" indicator will remain lit.
• If the "DSI FLT" light comes on during
operation, it means that the burner has gone
into "lockout" mode and must be restarted. If
this happens, turn the Water Heater switch
OFF for approximately 5 minutes, then turn
back on.
Further Information
See the Water Heater manufacturer's
operation manual provided in your InfoCase for
complete operating instructions, safety warnings,
and maintenance information.
PRESSURE-TEMPERATURE
RELIEF VALVE
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
Normally there is an air gap at the top of the
water heater tank, 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.
CAUTION
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.
