Burner Flame Checks - Bradford White RG275H6X-506 Manual

General Operation continued-
Hotter water increases the risk of scald injury. Scalding may occur within five (5)
seconds at a temperature setting of 140°F (60
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.

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 10). 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 11). 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
