Because the burner is not adjusted correctly, you are waisting fuel.

That unit has two flow sensors. It needs to register flow through both sensors in order for it to fire. If one of the flow sensors is stuck or if there is scale blocking flow through the heat exchanger, it will not fire. I'd recommend contacting a servicer to clean the unit.

Like a buzzing noise? Check valve where water lines connect at back will make a buzzing noise, if you only hear it when running hot water and not when running cold. Remove and replace it after shutting water off, and draining tank down. Be sure to shut off any hydro to electric element prior to draining.You can buy a replacement check valve, or just put a short 1/2" pipe nipple in there instead and reconnect your line, and refill it. noise should be gone .

Thank you for providing clear description of product:
Your water heater has intellivent gas control thermostat.
There are always problems with water heaters. It is a huge field.

1) Open following link for AO Smith service manuals.
I do not see service manual specifically for the GP series.

2) Open following link to identify gas valve and download typical service manual:
Some AO smith power vent models have intellivent gas valve, and some have smart valve gas vent. Older models might have knob-type gas valve.

How to change a envirotemp gas water heater into a.electric water heater


Dear Buffie,
You cannot change a gas water heater into an electric water heater, nor can you change them the other way around.
They are manufactured differently.
If, however, you are getting rid of the gas one and want to know how to hook up a electric water heater in it's place, please ask the question that way.
God bless your efforts.

Why does my pilot light keep going out when heating is on ?


Water heater and house heater are sharing the same vent?
Then vent is bad, and heater is pushing combustion by-product down into the water heater and blowing out pilot.
Call technician immediately to avoid CO poisoning.
Look for black soot on top of water heater... test the vent:

Is a 80 gallon hot water heater legal for a 7 apt. building?


You probably need commercial 150gallon gas water heater.
Or three 80 gallon tanks, depending on number of people.

80 gallon residential gas heater is rated for low-demand 6-8 person household.
80 gallon residential electric is rated for low-demand 5 person household

80 gallon is not correct for 14-28 people in 7 apartments

Call local plumber, or local code department.

Is the lower element suppose to have two legs of 120 to it? Or do i need to move a wire up top to make it 240? as it is on top element.


You have water heater with two elements.
Two-element water heaters are 240Volts.

1) Lets talk about what makes a 240Volt circuit
See basic water heater circuit:
http://waterheatertimer.org/B220C.html

Open link, and illustration at top of page is your water heater circuit

Notice that two insulated wires come from the circuit breaker and go to the water heater.
These two wires are 120volt each. When these two 120Volt wires combine, they create 240Volts
These are called hot wires because they come from the hot busbars.
There is also a bare copper wire that comes from neutral busbar.
The bare copper wire is a safeguard, and is not necessary for the 240V circuit to work.

Inside each circuit breaker box is 1 neutral busbar, and 2 hot busbars.
Open image below, and it shows typical residential breaker box
http://waterheatertimer.org/images/Inside-Main-Breaker-Box-420.jpg

In a residential home, each circuit takes two wires to complete the circuit.
For 120Volt circuit, you need 1 neutral wire and 1 hot wire to complete the circuit. These are usually a black and white wire. The bare copper wire is a safeguard.
For 240Volt circuit, you need 2 hot wires to complete the circuit, and each hot wire comes off a different busbar. These can be a black and white wire, and sometimes a black and red wire. The bare copper wire is a safeguard.

With a 240Volt water heater the two hot wires connect to the black and red wires located on top of water heater.

2) Let's talk about wiring inside a water heater.
http://waterheatertimer.org/images/WH-w-combined-530.jpg

Open image on link above, and it shows your 240volt water heater wiring.
The 2 hot wires from breaker box connect to the red and black wires on top of heater.
Inside each water heater, the wires are color-coded and will appear the same, or nearly the same, as shown on link above.
As long as your wiring appears like the image, and the hot wires from breaker box connect correctly, and the circuit breaker is working fine, then your water heater will work.

Add a comment any time.

Low pressure at hot water tap


Most tankless heaters will normally restrict the hot water output in order to maintain a stable outlet temperature; however, this should only be noticed if you have several hot water fixtures open. If you are only seeing the problem when running a single fixture, then the problem is probably one of these items:

1) clogged aerator on your fixture - easily fixed by removing and cleaning the aerator with a pair of vice grips

2) clogged inlet filter for your tankless - the inlet filter is located on the incoming cold water connection. It has a black cylindrical cap. To remove it, make sure to first turn off your water to the heater and then unscrew the cap to remove the filter. Instructions can also be found in your owner's guide.

Error code 14 shows on the remote for a noritz tankless lpg water heater. what does it mean?


This means the thermal fuse has broken and needs replacement. The thermal fuse is a white cord which wraps around the heat exchanger. It typically breaks if the unit is excessively dirty and sooted. Before the fuse is replaced you should make sure the unit is cleaned with compressed air and descaled.
