i
installation or after gas line work
has been done, air in the gas line

the hot water running and wait 3-5
seconds, then press reset button

ignition again, if the (EA or EC)
reappears then repeat this same
process until all air has been bled

When the heater is in operation you will hear its power
vent fan and burner operating. Upon turning off the hot
water flow the power vent fan will continue to operate
