BURNER FLAME INSPECTION
Check main burner every three months for proper flame
characteristics. You can see the burner flame through the sight
glass on top of the burner plate. To access the sight glass, you must
remove the plastic cover.

The main burner should display the following characteristics:
•
Provide complete combustion of gas.
•
Cause rapid ignition and carry over of flame across entire
burner.
•
Give reasonably quiet operation during initial ignition,
operation and extinction.
•
Cause no excessive lifting of flame from burner ports. See
Figure 50
.
Figure 50. Normal and Abnormal Burner Flames
If the preceding burner characteristics are not evident, check for
accumulation of lint or other foreign material that restricts or blocks
the air intake fitting or air intake terminal.
To ensure continued good performance, keep the area around the
water heater clean and free from lint and debris. Sweep the floor
around the water heater regularly. This will reduce the dust and dirt
which can enter the burner and heat exchanger, causing improper
combustion and sooting.
If the air intake fitting and air intake terminal are clear and the burner
continues to exhibit abnormal flames, contact a qualified service
agency or have a qualified service professional inspect and clean
the burner.
SERVICE
If a condition persists or you are uncertain about the operation of
the water heater contact a qualified service technician.
Use this guide to check a leaking water heater. Many suspected
leakers are not leaking tanks. Often the source of the water can be
found and corrected.
If you are not thoroughly familiar with gas codes, your water heater,
and safety practices, contact your gas supplier or qualified installer
to check the water heater.
Read this manual first. Then before checking the water heater make
sure the gas supply has been turned “OFF”, and never turn the gas
“ON” before the tank is completely full of water.
