Pressure - Temperature Relief Valve
The water heater is equipped with a Pressure-Temperature Relief Valve that may
discharge during the heating cycle due to thermal expansion of water. The Pressure-
Temperature Relief Valve is designed to open when the water temperature within
the heater reaches 210° F (98.8° C), or when pressure reaches 150 psi. Because the
unit utilizes a closed system, discharge is a normal occurrence and is not necessarily
a faulty valve. The water heater has an internal air pocket to reduce the possibility
of dripping or weeping. Eventually, the expansion of the water will absorb the air
pocket. When this occurs, utilize the following procedure to replace the air.
CAUTION:
Ensure the water heater tank is cool prior to checking the valve.
Re-establishing the Air Pocket:
1. Turn
Off
the water heater.
2. Shut
Off
the incoming water supply.
3.
Open
the hot water faucet closest to the water heater.
4.
Pull
the handle of the relief valve until the flow of water stops.
5.
Close
relief valve allowing it to snap shut.
Close
hot water faucet. Turn water supply
On
.
6. Turn
On
the water heater.
The air pocket is re-established; the process need not be repeated until the next discharge of water. If the
discharge does not stop, contact a qualified service center to evaluate the valve and make any required repairs.
Operation
The Water Heater Operates Under these Conditions:
120 Volt AC is supplied from shore power (preferred) or optional generator.
The manual valve on the propane tank is open.
The house battery is fully charged and on.
Both propane and electric functions can be on simultaneously for large volume
use.
Propane Operations:
The direct spark ignition water heater must have correct gas pressure and a DC voltage
range between 10.5 Volts DC and 13.5 DC Volts. This voltage is supplied directly from the battery or from the
filtered circuit of a converter.
Heating Water with Propane:
Make sure the propane is turned on.
Turn
on
the propane water heater switch.
CAUTION:
It is recommended not to operate the water heater on propane while the
motorhome is in transit. Be sure the water heater is off before refueling.
WARNING:
If a propane smell exists, extinguish all open flames and turn off the main propane supply. Propane
is highly volatile, highly explosive and extremely dangerous. Explosion, fire, property damage, injury
or death can result. Propane is a “heavy” gas and will lay on the floor and “hide” in corners. Open all
windows and doors. DO NOT touch any electrical switches. They may cause a spark that can ignite.
Evacuate the recreational vehicle and shut off the propane valve. Contact a qualified service center to
have the problem correctly diagnosed and repaired before resuming operation.
