SOURCE: Pentair Mininmax NT natural gas pool heater.

The Dianostic Lights when trying to start the heater is where to go next. When you tried to start the heater manually, did you have your automation system turned off so you can start it manually? If you did, when you tried to start the heater, wht happened? Did you receive any error codes? Were any of the System Indicator lights on? If you open the right hand side door, there will be a part with FENWAL on the sticker-near the top of the heater. Next to the word FENWAL, you should see a small arrow pointing up, there is a Red Diagnostic light above the arrow, is it flashing, and if so, how many times?


If you do not have an Owner's Manual for the heater, follow the link below and it will take you to one online. There are some trouble shooting ideas there also.

SOURCE: E04 comes on after fan purge cycle-Pentair minimax nt pool heater

This is a fan falure code. It can mean the fan has problems (not likley if the fan goes and isn't labored) You have a sensor in your exaust (probally not this if you don't get a good start) The culperet is probally in the negetive pressure sensor. This is a 2-3 inch disc with wires going to the controls and a rubber tube going to the fan. Pull the tube from the fan and make sure the fan fitting is clear (poke with a tooth pic) Be sure their are no kinks in the hose. If the heater is 4 years old the diaprahm could be bad in the pressure sensor. Check the other things first but this is probally your problem. Good luck, hope this helped.

SOURCE: pool heater is not working properly

So I assume you have pressed the button by pool to select the pool thermostat? If this doesn't work sounds like another mother board problem, or try powering down the unit a few minutes then restart. IF you haven't pressed the pool button, the read this: The heater comes factory set at 78° F. for the pool mode and 100° F. for the spa mode. If it's in spa mode it's trying to get to 100F. Using the up and down arrows,you can set the thermostats to a minimum temperature of 65° F., or a maximum of 104° F. If you desire to heat only one
body of water, the thermostat is capable of an off mode. As an example, if you only wish to heat the pool and not the spa simply depress and hold the spa down arrow, and the thermostat will lower its setting to 65° F. then go to an off mode. Here is a link to your manual :http://www.pentairpool.com/pdfs/MasterTempOM.pdf

SOURCE: I just purchased a Master Temp 400 for my pool.

Let me give you my opinion. If someone that has gas flow experience responds to your question, that would be better.
I would think that if you have a gas regulator serving your home that it would regulate all gas pressure for all devices regardless of the number of devices as long as the total gas consumption is less than what the regulator delivers.
I would have someone else quote on any additional work.

Hello I have a robertshaw 7100 see. Gas valve on me furnace and would like to know if it has both Nat. And propane orficess in it and how to change it from one to the other. Thanks brad


I'm not sure if the orifice can be changed on your valve, that is the only difference between natural gas and propane. I recommend calling your local plumbing supply store for exact specs but the gas valve shouldn't be much $$$

How change robertshaw 110-32f


Turn off gas to the heater close water supply drain the water out of heater.Remove pilot tube assembly remove thermocouple/or thermopile assembly disconnect gas at the union and remove from valve. Use wrench that fits the hex shaped nut that holds the aquastat and water heater in the tapping. Usually the wrench size is 3/4" or 7/8" depending on the unit.

Put pipe dope on the male thread of the valve and keep it off the aquastat bulb, and rethread into the tapping.

Replace the ilot assembly being sure it was not damaged when it was remover if it was damaged replace it. replace the thermocouple/powerpile assembly replace the gas piping from the valve being sure to use pipe dope on the fittings and tighten them enough so they do not leak. Do not use teflon tape because it could get into the gas valve and cause problems.Test the gas piping for leaking do a tight test on the meter if possible or test with testing fluid and look for bubbles or use a gas leak detector that sniffs for gas and beeps when it detects a leak

Fill the water heater up with cold water and check to be sure there are no leaks at the thread where the valve is threaded into the tapping. Open a hot water faucet and be sure the heater is full of water.

Light the pilot and turn the gas on set to the temp that is best suited to you..

Gas valve for hot water unit is faulty


To replace it, you'll need to know whether it's a Robertshaw or Maxitrol Valve. As well as the Model number of the valve and whether it's Natural Gas or Propane Gas. Unless, you're really experienced with working on gas appliances, I would not recommend this as a DIY project.

Hope this helps solve your problem.

I have a raypak heater with robertshaw 7000 gas


Remove the wires from the gas valve and call for it to light. While it is trying to light, take a voltage reading on the wires that go to the valve. If it is sending voltage to the valve and it won't energize the valve then the valve is defective. Just make sure that the valve is being told to come on. It could just be a limit switch. Double check the manual reset limits also before doing the vavle check. Hope this helps.
