If the water heater is not properly derated, poor efficiency in heat-
ing the water may occur due to incomplete combustion. You may
also notice pilot outage caused by burner lift-off or sooting from
a yellow burner, indicating the possibility of carbon monoxide.
For proper change out of the orifice
(
derating
)
consult with a local
propane company, your dealer, or the water heater manufacturer
.
IMPORTANT NOTE:
Once the RV is returned to lower elevation
(below 4500 feet) any high altitude deration or other the water
heater adjustments
must be reversed
for proper operation.
Pressure and temperature relief valve
The Pressure and Temperature Relief Valve (P & T Valve) is a
mandatory safety requirement for all water heaters. As cold
water is heated, pressure in the water heater tank increases.
The P & T Valve will release any unsafe pressure from the water
heater tank.
It is normal for a small quantity of water to also be released from
the P & T valve during the heating cycle. To reduce water dripping
from the P & T relief valve:
•
Maintain an air pocket at the top of the water heater.
(Please refer to the manufacturer’s manual).
◦
This air pocket forms in the tank by design.
◦
Everyday use of your water heater will reduce
this air pocket over time.
If the weeping persists, consult your dealer or a service agency
authorized by the water heater manufacturer.
Inside the Exterior Water Heater Door - as equipped
DO NOT replace any
component part
with
an
accessory part
that
is not
authorized by the
water heater manufacturer,
such as an
add-on
electric
heating element.
Such items are not approved
to be installed and could
create an unsafe condition
and will void all warranties.
WARNING
Water temperatures over
125°F (49°C) can cause
severe burns instantly or
even death from scalds.
BE CAREFUL WHEN
USING HOT WATER.
ALWAYS test the water
temperature BEFORE
showering or washing.
