Burner Flame Checks
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.
WARNING
Do not run out of propane gas. Damage to the water heater may occur.
WARNING
Hotter water increases the risk of scald injury. Scalding may occur within 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 fail 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.
