Question about Noritz 7-9.4 Adjustable Tankless Wtr Heater Vent Pipe

1 Answer

We have a timer on our tankless hot water heater-how do I set it to reflect the current time? It is a large dial with tiny pins to pull/push backward. I understand the on off function of the pins but need to know how the dial corresponds to the actual time.

Very simple you push the middle and turn to set it to the timing you want current timing. the best times to set a recirculating pump in a water heater is 20 to 30 min before you take a shower in the mornings 15 min is adeal and dont leave the timer on for more than 15 min which represents each pin. Remember you are trying to recirculate the cold water out off the lines and replace it with new water so next time you open your faucet you get instant hot water. ones hot water is in the line you do not need the pump. i also recomend to set the pump 15 min before you get home or before you take a shower int he afternoons there is really no pint to leave the pump all day or for longer than that because the objective is to replace cold with hot water you can even set it to turn on and off every hour for 15 min at a time if someone is home all day but remember usually the recirculating pump is there for the faucets that are far away from the water heater so if you do not used them all day and only in the morning and at night before going to bed then there is really no point to leave the pump on and waste more electricity.

Sometimes there is a raised mark you can feel with finger.
Another way is to look down into the groove where the timer dial rotates.... and locate the tiny switch that is pushed when dial rotates... this will be the current time location... this will generally be 1-2 hours before or 1-2 hours after top center

I want to reset the timer for hours of on-off for out water heater but can't figure out how to push the little white teeth in or out. Model is 265-1.


1) Open following link to read about re-circulation systems:
http://waterheatertimer.org/Water-heater-recirculation-system.html

2) Image below show typical FM1 analog timer dial with pins:
Move pins with fingernail or small tool.
To test if pins need to be moved in or out, set pins each direction and manually rotate dial clockwise and listen when pump turns on-off.
How timer operates: clock motor rotates dial continually, pins on dial move lever that turns circuit on-off.
To set current time, manually rotate dial clockwise until current time lines up with arrowhead located on inner dial.
Some timers have a selector switch: move switch to Auto, or Timer, or Timer ON. Again you can manually rotate dial and check which setting is correct.

How do I set a plug in timer GE 24 hour Model 15075? There are tiny switches for every hour and can be pushed towards the inner circle or pushed outward. And there is a turning arow near the center and a...


Following link has a close-up photo of on-off pins on GE 15075 timer
http://waterheatertimer.org/GE-timers-and-manuals.html#15075

Pins are located around timer dial
The pins divide 24-hour day into 1/2 hour segments
Pins are out for ON
Pins are inward for OFF
Notice that numbered dial is divided into dark and light areas ... the dark areas are PM, light areas AM.

For example you are connecting chicken coop lamp to this timer.
Turn lamp on and make sure bulb is working.
Plug lamp into timer.
Set pins in and out as follows: all pins outward between 4:30 pm on light part of dial to 8:00 pm on dark part of dial. And then set all pins outward between 5:00am on dark part of dial to 7:00 am on light part of dial.
Plug timer into outlet
Move switch located on top to TIMER ON
Manually rotate timer dial clockwise to see lamp turn on and off.
Lastly, set current time: Manually rotate timer dial clockwise until current time lines up with arrowhead located on inner dial. So if current time is high noon, then rotate dial until 'sun' symbol located on light part of dial lines up with arrowhead.
As time passes, the timer dial rotates, and the pins click circuit on-off.
To override timer, move switch to outlet-on.

I think you have a grundfos recirculation pump.
This is not a water heater timer.
For illustration of grundfos system, open link below.
http://waterheatertimer.org/Water-heater-recirculation-system.html
Recirculation system is electric, but it also causes gas water heater to run more.
Unplug grundfos for a couple months to see if gas bill goes down. Your system will revert to regular water heater.

Many things can cause high gas bill. Make inventory of gas-consuming appliances: dryer, oven, stove, heater, water heater. Then inventory how often these appliances are used. Each appliance has a label with BTU listed. Add up BTUs of all appliances and compare with BTUs shown on gas bill. Call gas company about how to cut back.
Gas water heaters can become inefficient. So can any gas appliance. Look at flame inside water heater when it turns on. If flame is yellow instead of clear blue, that indicates the water heater is inefficient, and burner needs to be cleaned, or heater needs replacement or maintenance.
Call plumber for assessment and then post a question on the Tank to double check anything plumber says:
http://www.thetankatwaterheaterrescue.com/forums/forum3/

More information about circulation system:
Notice that illustrations show a pump located under the sink.
It sounds like you have same pump located at water heater.
Both types are same thing.
The purpose is to circulate hot water to your faucet so you don't have to wait for hot water when turning faucet ON. Instead, you have to wait for cold water.

The timer located on grundfos dial determines when pump turns ON.
Link above has illustration showing how to set timer pins using your thumb or ink pin or nail file (women know nail files, so I'm relating here).
To set timer, rotate dial until current time lines up with mark. The dial rotates as time passes and has to be reset after power outage.
If dial does not rotate, then timer is broken, but it sounds like pump is still working, and running full time which is wasteful.
Next, move the pins to set on-off times. Move pins inward, the pump is ON. Pins outward, pump is off.

The hot water recirc pump in my new house was equippped w/ this timer. There was no user manual, but it was set by the installer to run the pump during awake hours and shut it off during sleep hours. ...


1) Open link below so we are talking about same type of household system
http://waterheatertimer.org/Water-heater-recirculation-system.html

2) 15 minute interval is misleading.
Pins located on timer dial divide 24-hour day into 15 minute intervals.
You set timer pins and decide which 15 minute intervals you want ON-or-OFF. Do this by moving pins inward or outward with your thumb or ink pen. To check settings, manually rotate timer dial clockwise and listen for pump turning on-off..
Set timer pins for 4 consecutive 15 minute intervals, then timer runs for 1 hour.
After pins are set, then manually rotate dial to set current time.
Dial rotates as time passes, and pins click a lever that turns pump on-off.

3) 5-year Life span. Like all things plumbing, if you have hard water or sand-n-dirt in water lines, then pipes clog. And pumps clog.
Once motor begins to slow down, it overheats and burns out.
Water softener can keep sediment out of lines, but shortens life of water heater.
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html

4) Real question: do you need a circulation pump? Do you need hot water at your faucet? Can you schedule hot water use, or does recirculation pump have to run several hours per day?
Recirculation pumps causes water heater to run more, the pump consumes 25+ watts depending on pump, and water savings claims of 15,000 gallons per year are fabrication.
Realistic water savings is 700-2000 gallons per year, assuming several folks in the home use water sporadically across a full day, and each time water is used people are waiting for hot water. It also assumes that you never want cold water at the tap and that refrigeration ice maker line prefers hot water to cold.

5) Add a comment for more free help.
Also take advantage of fixya phone service.
For a price, fixya expert speaks with you over phone while you work on pump/timer or any do-it-yourself project.

Timer will not turn water heater ON at set time, has to be done manually. However, it will turn water heater OFF at set time.


If this is new installation, check wiring. Hot and Load wires might be reversed.
Check that ON OFF trippers are both attached to yellow dial.
http://waterheatertimer.org/How-to-wire-WH40.html

If timer worked fine before, and started missing recently, then tripper pins probably worn out.
Trippers contact mechanical lever, and push lever on-and-off.
Trippers are softer metal and designed to wear out before lever.
If lever is worn out, timer needs to be replaced, but try new trippers first.
Buy trippers at Grainger
http://www.grainger.com/Grainger/INTERMATIC-Timer-Tripper-2E054?Pid=search
http://www.grainger.com/Grainger/timer-accessories/timers/electrical/ecatalog/N-8hi

How WH40 timer works:
Clock motor rotates dial.
ON-OFF trippers on dial contact lever.
ON tripper pushes lever one direction.
OFF tripper pushes lever other direction.
Lever moves electrical contacts together, or pulls contacts apart.
When lever moves on-and-off, manual override lever also snaps back and forth with audible clicking sound.

Using q-tip, add touch of white grease to lever where trippers contact.

The timer is used on an Electric Point of Use 2.5 water heater. Currently I get hot water only about two hours in the evening. Before it was --on demand. I opened the timer box and one of the timer box"...


No overcharges here Ms bernarda

If I understand correctly you have Intermatic timer with a yellow dial
You have the Intermatic timer hooked to a small 2-1/2 gallon point-of-use water heater
Your point-of-use water heater is working fine
The timer turns on the water heater once a day instead of twice a day

And it seems like one of the tripper pins has fallen off the yellow dial
The tripper pin is missing and you can't find it or put it back.
You can turn off the electricity and poke around the bottom of the timer box and see if tripper pin can be pulled out using tweezers
Do you know Grainger sells Intermatic tripper pins for $1.67 plus shipping?

The instructions indicate to push the outer segments down with pen, etc to set timer. I can't get the segment to go down.


Generally the segments are already pushed down when you buy timer.

Instruction usually say, pull up all the segments, and after pulling up all the segments, then push down the segments for the hours you want the timer turned OFF or ON depending on timer

1) The silver pin goes at 12 midnight on large yellow dial. This pin advances the skipper wheel each day.
2) Turn yellow dial clockwise until current time lines up with silver pointer.
3) Rotate skipper wheel counter-clockwise until today's day (Monday) is in front of 14 arrow.
4) To skip a day of watering, the skipper pin is pushed down for that day. So you want to push down Monday and Tuesday.
For watering, the skipper pins is up for that day. So you want The skipper pin up for Tuesday.
5) The brass trippers are inserted on yellow wheel. Each brass tripper represents 12 minutes of watering for example. So if you want to water for 1/2 hour, then put two consecutive pins on the yellow timer wheel. For 1 hour, put 4 consecutive pins.
