WARNING
Do not run out of propane gas. Damage to the water heater may occur.
(5) seconds at a temperature setting of 140°F (60°C). To protect against hot
water injury, install an ASSE approved mixing valve in the water system. This
valve will reduce point of discharge temperature by mixing cold and hot water in
branch water lines. A licensed plumbing professional or local plumbing
authority should be consulted. Note: This water heater is equipped with an
energy cut out device to prevent overheating. Should overheating occur or the
gas supply fails to shut off, turn off the manual gas control valve to the
appliance and call a qualified service technician. Note: Whenever the water
heater is filled with cold water, condensate will form on the cool tank surface
and drops of water will fall on the hot burner and combustion chamber surfaces
producing a “sizzling” noise. Condensation is normal and does not indicate a
BURNER FLAME CHECKS
Cast Iron Burner: At t he time of installation and at periodic intervals (not m ore than 6
months), a vis ual check of the main burner and pilot flames should be made to determ ine if
they are burning properl y. For ideal operation, the gas and air must be properly
proportioned. The proper air-gas mixture is obtained by adjusting the air shutter on the
mixer face of the main burner (See Figure 6). To adjust for proper burning, loosen the air
shutter nut, r otate shutter to close t he opening in the burner then slowly rotate the shutter
until the yellow tips disappear and the flame becomes blue. Tighten the air shutter nut. Too
much air will cause the flame to lift of f the burner ports and create noisy operation. Too little
air will result in soot formation. The m ain burner flame should light s m oothly from the pilot.
Steel Burner: These models ar e equipped with self adjusting air m ixture and do not have
an adjustable air shut ter (See Figure 5). At periodi c intervals, a visual c heck of the main
burner and pilot flam es should be made to determine if they are burning properly. The main
burner flame should light smoothly from the pilot.

GASOLINE OR PAINT THINNER TO BE USED OR STORED IN THE
VICINITY OF THIS WATER HEATER, VENT-AIR INTAKE SYSTEM OR IN
ANY LOCATION FROM WHICH FUMES COULD REACH THE WATER
MAINTENANCE
The following maintenance should be performed by a qualified service technician at
the minimum periodic intervals suggested below. In some installations, the
maintenance interval may be more frequent depending on the amount of use and the
operating conditions of the water heater. Regular inspection and maintenance of the
water heater and vent-air intake system will help to insure safe and reliable operation.
1. Annually check the operation of the thermostat.
2. The flow of combustion and ventilation air MUST NOT be restricted. Clear the
combustion air openings of any dirt, dust, or other restrictions. WARNING! The
ventilation air system may be HOT.
IMPORTANT
The water heater should be inspected at a minimum annually by a qualified
service technician for damaged components and/or joints not sealed. DO
NOT operate this water heater if any part is found damaged or if any joint is
found not sealed.
3. At all times keep the water heater area clear and free from combustible materials,
gasoline and other flammable vapors and liquids.
4. Bi-annually conduct a visual check of the main and pilot burner flames to
determine that they are burning properly. See Burner Flame Check section.
5. Annually remove the inner door and main burner assembly to clean orifices and
related parts of any dirt or other foreign material. Inspect the burner ports for
obstructions or debris and clean with a wire brush as needed. Wire brush and/or
vacuum clean the combustion chamber as needed to remove scale deposits and
debris. NOTE: It is imperative for proper operation of the water heater that the
inner door be replaced in the original location.

relief valve, hot water will be released under pressure. Be careful
that any released water does not result in bodily injury or property
6. At least once a year, check the combination temperature and pressure
relief valve to insure that the valve has not become encrusted with lime.
Lift the lever at the lever at the top of the valve several times until the valve
seats properly without leaking and operates freely.
7. Monthly drain off a gallon of water to remove silt and sediment.
8. If the combination temperature and pressure relief valve on the appliance
discharges periodically, this may be due to thermal expansion in a closed
water supply system. Contact the water supplier or local plumbing
inspector on how to correct this situation. Do not plug the combination
temperature and pressure relief valve outlet.
9. A combination sacrificial anode rod/hot water outlet nipple has been
installed to extend tank life. The anode rod should be inspected
periodically (every 2 years) and replaced when necessary to prolong tank
life. Water conditions in your area will influence the time interval for
inspection and replacement of the anode rod. Contact the plumbing
professional who installed the water heater or the manufacturer listed on
the rating plate for anode replacement information. The use of a water
softener may increase the speed of anode consumption. More frequent
inspection of the anode is needed when using softened (or phosphate
treated) water.
