B. Periodically inspect unit for soot. If soot is present anywhere on water heater,
immediately shut unit down and contact your dealer or a qualified service person.
Soot is a sign of incomplete combustion and must be corrected before operating
water heater. Areas to check would include:
1. Check for an obstruction in burner or the flue box.
2. Check the screen in the door to see that no foreign material has accumulated
to prevent flow of combustion and ventilating air.
3. Check to be sure there is no flame present at burner orifice or burner whenever
main gas valve is closed. This can be checked by turning the OFF\ON switch to
the “OFF” position.
C. Frequent checks should be made of the grommet on the gas inlet to assure
tight seal. (See “Making Gas Connections”).
D. Periodically check wiring and wire connection to be sure wiring is not
dam aged/frayed and that all terminals and connections are tight and in
compliance with codes (See “Making W ire Connections”).
SAFETY WARNINGS
WARNING! It is imperative that the water heater tank be filled with water
before operating the water heater. Operation of the water heater without
water in the tank may result in dam age to the tank and/or controls. This
type of dam age is not covered by the limited warranty.
WARNING! Hydrogen gas may result if you have not used this heater for
two weeks or more. HYDROGEN GAS IS EXTREMELY FLAMMABLE. To
reduce the risk of injury under these conditions, open the hot water faucet
for several minutes at the kitchen sink before you use any electrical
appliance connected to the hot water system. If hydrogen is present, you
probably will hear an unusual sound such as air escaping through the
pipe as the water begins to flow.
Hydrogen gas may be present even after water has been drained from the
tank. Open faucet at sink and allow system to vent for several minutes (5-
10 minutes).
Do not smoke or have any open flame near the open faucet. Do not
attempt to light pilot or main burner. On DSI models, be sure the switch
is “OFF”.
Should overheating occur, or the gas supply fail to shut off, shut off the
manual gas valve to the appliance before shutting off the electrical supply.
Do not use this appliance if any part has been submerged under water.
Immediately call a qualified service technician to inspect the appliance
and to replace any part of the control system and any gas control that has
been submerged under water.
Do not alter the operation of your water heater nor change the
design/construction of your water heater. Accessories are being marketed
for RV products which we do not recom mend. For your safety,
only factory authorized parts are to be used on your water heater.
Periodically inspect the vent for obstructions or presence of soot. Soot is
formed whenever combustion is incomplete. This is your visual warning
that the water heater is operating in an unsafe manner. If soot is present,
immediately shut the water heater down and contact your dealer or a
qualified service person.
When considering add-on rooms, porch or patio, attention must be given
to the venting of your water heater. For your safety, do not terminate the
vent on your water heater inside add-on rooms, screen porch or onto
patios. Doing so will result in products of com bustion being vented into
the rooms or occupied areas.
Never operate the heater if you smell gas. Do not assume that the sm ell
of gas in your RV is normal. Any tim e you detect the odor of gas, it is to
be considered life threatening and corrected immediately. Extinguish any
open flames including cigarettes and evacuate all persons from the
vehicle. Shut off gas supply at LP gas bottle. (See Safety notice on front
cover of this manual.)
NOTE: Always open both the cold and hot water faucets when filling
vehicle water tank to allow air pockets to be forced out of the water heater.
When water flows from the heater faucets, close both faucets.
WARNING! Do not store or use combustible materials or liquids near or
adjacent to this heater. The appliance shall not be installed in any location
where flamm able liquids or vapors are likely to be present.
Be sure the power is "OFF" to the water heater ignition system during any
type of refueling and while vehicle is in motion or being towed.
The thermostat on your water heater is not adjustable. It is a temperature
sensing limit designed to maintain a water tem perature of 130°F (54°C).
Water temperatures over 125°F (49°C) can cause severe burns instantly
or death from scalds; therefore, be careful when using hot water.
Children, disabled and elderly are at highest risk of being scalded. Always
feel water before bathing or showering.
HIGH ALTITUDE DERATION
Suburban’s water heaters are certified by nationally recognized testing
laboratories for operation without modifications at altitudes up to 4,500 feet.
Operation above this elevation may require derating by 4 percent for every 1,000
feet above sea level. As an example, at 8,000 feet, the water heater should be
derated approximately 32 percent.
If the unit is not properly derated, lack of sufficient oxygen for combustion may
produce improper burner operation. Pilot outage caused by burner lift-off or
sooting from a yellow burner may occur indicating the possibility of carbon
monoxide. You may also notice a lack of efficiency in heating the water because
of incomplete combustion of the burner at these higher altitudes.
Consult with the local gas company, your dealer, an RV service agency or
Suburban Manufacturing Company for proper derating of the unit. Change-out of
the orifice (derating) should be done by the dealer or a qualified service agency.
NOTE: It is important that once the unit has returned to lower elevation (below
4,500 feet) this high altitude deration and pilot adjustments (if equipped) be
reversed for proper operation of the unit.
ANODE PROTECTION
The tank in this water heater is protected by a magnesium or aluminum anode to
prolong the life of the tank by absorbing the corrosive action of hot water. Under
norm al use, the anode rod will deteriorate and because of this, we recommend it
be replaced yearly. NOTE: W ater with high levels of iron and/or sulfate will
increase the rate of deterioration; therefore, more frequent replacement may be
required. If anode rod is mostly eaten away, replace it with a new one. (See
Figure 11)
To prevent a water leak when replacing the anode rod, a pipe thread sealant
approved for potable water (such as Teflon Tape) must be applied to the threads
of the anode rod. Proper application of a thread sealant will not interfere with the
anode’s tank protection.
Operating the water heater without proper anode protection will decrease tank life
and will void your warranty on the tank. NOTE: Tank is drained by removing anode
rod (See “Drain and Storage” instructions).
To extend anode life, drain water from tank whenever RV is not being used. Avoid
any extended time of non use with water in tank.
Also, refer to section on winterizing.
WARNING! Do not replace the anode rod with any non-Suburban
accessory part, such as an “add-on” electric heating element. Items such
as these are not approved to be installed in Suburban products. They
could create an unsafe condition and will also void all warranties.
