The main burner must be on
for this test. With a newly
installed water heater full of
cold water, turning the temperature
control knob to HOT should cause the
main burner to come on. You can view
the burner through the sight glass at
the base of the water heater.

Close all windows and doors
and turn on all gas appliances
and air-moving devices (range
hoods, bathroom exhaust fans, ceiling
fans, etc.) in your home. Also, close any
