Question about Hayward 2001 Series Millivolt Gas Pool Heater 200000 BTU ()

1 Answer

Can/ how to adjust millivolt seeting for a lower power pump?

My 2001 model heater is about 15 years old. It worked when first installed. A couple of years ago we bought a new pool pump which has only one speed. The pump does not generate enough pressure to cause the heater to light. Is there a way I can adust the millivolt setting so that the heater will light? If yes, please describe the adjustment that I need to make.
thanks,

Before you do anything, check with Hayward as to the minimum flow they require to maintain safe temperatures in the heater. You may have to throttle the heater back. They may have a lower value pressure switch you could use, too.

THE PILOT LITE IS LIT BUT HEATER WILL NOT FIRE. I JUMPED THE THEMOSTATE BUT STILL WONT FIRE. THE HEATER IS ONLY TWO YEARS OLD? IT IS A MILLIVOLT HEATER 206


You have a "Standing Pilot" system with a thermocouple which generates millivolts to energize the solenoid on the gas valve causing it to open. This allows the gas to enter for heating.
The majority of the time this thermocouple goes bad and needs changing.bobicehouse_4.gif

How do you convert a remote thermostat to a directly wired digital thermostat to a vulcan powerhouse 100 central heater unit


First, you need to know how many millivolts the Thermopile (aka Pilot Generator) on the the furnace's pilot assembly millvolt terminal. Then you find a wired digital thermostat, that meets the same millivoltage that the Thermopile Generates or has a lower requirement. You have to run millivolt wiring from the furnace's pilot assembly millivolt terminal block (the wiring should be connect to the TH & the TPH terminals, to where you want to place the digital wall thermostat. In most cases, it can not be more that 15' away from the furnace. In other words, no more than 15' of wiring can be involved.

Hope this helped you. Please let me know. Thanks.

Heater starts and runs for several minutes and then turns off


Since the unit runs for a couple minutes, I would first check for proper water flow. Find the pressure switch. It is usually round with two wire terminals and a copper/metal tube attached to it. With the wires attached, use a jumper wire to bypass the switch. If it runs longer check for flow problems.. (WARNING don't jump the switch for too long!!! Just enough time to see if the run cycle improves). Clean all the skimmers baskets, pump basket, backwash the filter (if a cartridge filter clean the filters). Try firing the heater again. If it still shuts down, replace the pressure switch. I never recommend adjusting it. Adjusting it too low can damage your heater and/or cause injury.

Timing chain is loose how do I replace or tighten


You need to pull out the timing cover. 4-6 hours of work. Here is the step to remove the Cover, then you need to remove the Sprockets.
moz-screenshot.pngmoz-screenshot-1.png
  1. Remove the oil pan.
  2. Remove the power steering belt if so equipped.
  3. Remove the air conditioning belt, compressor and bracket if so equipped.
  4. Remove the fan clutch (fluid coupling), with the fan and water pump pulley.
  5. Matchmark and remove the crankshaft pulley(s). This bolt will be very tight. Use the counter-holding bar, properly installed, to hold the crankshaft while loosening the bolt. Use the pulley extractor or gear puller to remove the pulley from the shaft.
  6. Remove the water bypass pipe.
  7. Remove the fan belt adjusting bar. If necessary, remove the lower power steering bracket for access.
  8. Disconnect the heater water outlet pipe.
  9. Unbolt the timing chain cover assembly. Be careful to loosen only the correct bolts.

To install:
  1. Install new gaskets over the dowels on the timing chain cover. Slide the cover assembly over the dowels and pump spline. Insert the retaining bolts and tighten them. Tighten the 8mm bolts to 9 ft. lbs. (13 Nm) and the 10mm bolts to 29 ft. lbs. (39 Nm).
  2. Temporarily install the adjusting bar to the alternator. Install the adjusting bar to the chain cover and tighten the bolts to 9 ft. lbs. (13 Nm).
  3. Install the heater water outlet pipe.
  4. Install the water bypass pipe.
  5. Install the crankshaft pulley and bolt. Use the counter-holding tool to hold the pulley and tighten the bolt to 116 ft. lbs. (157 Nm). If equipped with air conditioning, install the second crankshaft pulley.
  6. Install the water pump pulley and fluid coupling with the fan.
  7. Adjust the tension on the drive belts.
  8. Install the air conditioning compressor bracket, compressor and belt if they were removed.
  9. Install the power steering belt and adjust it.
  10. Attach the oil pan.
  11. Install the radiator.

Heater will not stay lit!!!


Lets start with safety. Check your vent pipe for obstructions, mainly outside at the vent cap. The safety of this unit will not allow it to operate if there is anything blocking the vent. If all is OK, then next we will light and observe the pilot with it on the pilot setting on gas valve. The pilot flame should consume the tip of the generator point by 1/2 to 5/8". If it does not, then screw off the pilot adjust screw cover on the gas valve. This is clearly marked on the top of the valve. Inside you will have a much smaller screw. Turn it counter clockwise to raise the pilot level, clockwise to decrease. Never consume more than 5/8" of the generator tip. Hopefully your problem will be resolved here at this step. If however it is OK, then take a millivolt meter and read the generator millivolts, at the gas valve with the thermostat contacts closed. It should read 140 millivolts. You need this much power to properly operate the heater. If it is lower than 140, then replace the pilot generator....Rob Just a note...Do not remove or take apart any part of the Gas valve, other than the pilot adjust screw cover...Good Luck.

Need flow rate and pressure adjustment proceedure for an old raypack 266 not electronic.thanks murray


The maximum flow rate for that heater to be installed in without a bypass is 125 GPM. The owner's manual can guide you thru gas pressure adjustments or adjusting the set point of the water pressure switch. Please note that unless you are installing the unit below or significantly above the water line you should not have to adjust the pressure switch. Whenever you do adjust it, be certain to turn the pump on and off several times to be certain the heater reacts to the pump condition...failure to shut down when the pump does can be a serious and dangerous condition.

Model-88h-300-top element works no power to lower


Check again. Is there power to it but it's not working? If so, the bottom element is the one that always fails first because the sacrificial anode gets used up and deposits collect on the bottom creating a blanket of "insulation", making it not heat water and causing it to overheat (elements MUST be submerged, or they will burn up.) Chances are your element is bad. Replace, or if the water heater is more than 15 years old, get a whole new water heater. Good luck.

Go to www.grainger.com and look for a "power pile generator" this is a millivolt thermocouple that may be just what you need to make your heater work again

I have a Raypac C155A LP spa heater. won't light


I would agree with you. The pilot generator has probably degraded over the years and is only proving enough millivolts to power the pilot but not enough to run the gas valve for your main burners.

Replacing the pilot generator, preferably the entire pilot assembly, will fix the problem.
