Anode Rod Protection (if so equipped)
The tank of the Suburban water heater is protected by a mag-
nesium or aluminum Anode Rod . The rod absorbs the corrosive
action of hot water to prolong the life of the tank. Through normal
use, the anode rod will deteriorate. If water contains high levels
of iron and/or sulfate, an anode rod will deteriorate faster; requiring
more frequent replacement. The water heater manufacturer
recommends that the anode rod be replaced annually or when
consumption / weight loss is greater than 75 %. See the photo
at the bottom of the page .
Operating the water heater without the proper anode rod
protection will decrease tank life and will void the manufacturer’s
warranty. To extend the anode life, drain the water from the
water heater tank whenever the RV is not being used. Avoid any
extended time of non-use with water in the tank.
When replacing the anode rod, use a pipe thread sealant that is
approved for potable water (such as Teflon Tape) on the threads
of the anode rod to prevent a water leak. Proper application of a
thread sealant will not interfere with the anode’s tank protection.
Pressure & Temperature Relief Valve
The Pressure and Temperature Relief Valve (P & T Valve) is a
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.
(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.
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.
