BURNER FLAME CHECKS
Cast Iron Burner: At the time of installation and at periodic intervals (not more than 6
months), a visual check of the main burner and pilot flames should be made to determine if
they are burning properly. 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 11). To adjust for proper burning, loosen the air
shutter nut, rotate shutter to close the 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 off the burner ports and create noisy operation. Too little
air will result in soot formation. The main burner flame should light smoothly from the pilot.
Steel Burner: These models are equipped with self adjusting air mixture and do not have
an adjustable air shutter (See Figure 10). At periodic intervals, a visual check of the main
burner and pilot flames should be made to determine if they are burning properly. The main
burner flame should light smoothly from the pilot.
DANGER
Hotter water increases the risk of scald injury. Scalding may occur within five (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 leak. It will disappear when the tank becomes heated.
WARNING
Do not run out of propane gas. Damage to the water heater may occur.
