Hurricane Heater COXL-45

Yahoo Message Number: 93004
Recently I posted success in "repairing"? my recalcitrant Hurricane heater (2002 model fitted in our 2003 Allure). The main actions were replacing the fuel filter, blowing our the fuel lines and cleaning the injector nozzle.

After running just fine for 10 days or so, today it has shown a renewed bout of fits. The result is Code 7 = Flame out.

I have:

- checked fuel supply from the tank - fuel filter

- dismantled and cleaned: injector nozzle, flame sensor, ignitor, burner chamber (this was clean, only some very light grey dust indicating lack of fuel I think) - checked solenoid: it's clicking when applying 12v directly - checked fuel pump: it wasn't running. Disconnected the FP ground connection at the "aquastat"? at the end of the water tank. Then reconnected: the fuel pump works & pumps fuel back via the return line.
So I thought I'd found the problem.

Not so.

The Hurricane will fire for about 1 second then quit. No smoke at all. Will repeat this sequence 2 x more and then go back to "Code 7"?.

Tomorrow I'll try cleaning the fuel regulator.

As I'm fast approaching the limits of my abilities, any ideas from this group will be most appreciated.

Merry Christmas to all,
Dick

Dick, I have an 03 Allure w/ XL 45 Hurricane, you didn't mention Air Compressor. Back in the mid 2000's ITR recommended going to a improved model of Air Compressor which I did. At that time it corrected my Flame Out problems.

Also have you tried to adjust the Tee Valve from fully closed to 1/4 turn - full turn open?

Thanks, Mike 03 Allure 1st Ave. #30898

Two things come to mind, the ignitor or lack of fuel. When mine flamed out on start-up, it turned to be the ignitor. But, I was getting white smoke (unburned fuel). The question is, is the fuel pump PSI up to spec? Or, is there air in the fuel lines caused by cracked lines? You can confirm a fuel line issue by using a separate gas can to feed your Hurricane. As a precaution, we changed our fuel lines and noted much deterioration where the lines were exposed to the elements at the coach gas tank. We have the same Hurricane unit. Good luck.

Yes, I forgot the air compressor too. As Mike points out, that is a likely culprit, and would explain the lack of white smoke.

Mike, Larry,

Thanks for your replies.

No I have not looked at the compressor for 2 reasons:
1. it was replaced by a used one 2/2011. At the time it meant an increase in air pressure from 5 psi to 8 psi.
2. I don't have a means of testing it's output other than using my finger and guessing.
You are right, it may be faulty.

The T-valve is always cracked open about ½ turn. I tested fuel flow with the T-Valve fully open: fills a 500cc / 17oz plastic bottle pretty quickly.

Fuel feed and return lines from the tank to the Hurrican and back were replaced in 2011. Fuel flows spontaneously via the feed line (and through the separate fuel filter) when disconnecting at the Hurricane and holding the open end lower than the fuel level in the tank. So no apparent restrictions here.

I'll have another go at the section from the fuel pump down to the regulator and the body that holds the nozzle and the photodiode.
And see if the compressor blows any air.

Thanks,
Dick

Dick, you can just disconnect the outlet hose to the compressor and apply 12 volts the the motor and feel for compressed air coming from the outlet. I did this and didn't detect compressed air, the disassembled it by removing the 4 screws on top and found a broken flapper valve.

Larry,

Tested the compressor as you indicate: it runs and puts out compressed air.
Tested fuel pump once more: disconnected hose at regulator and fuel flows freely

The search continues.

Up-date:

Removed and cleaned:
-fuel regulator,

-flexible hoses inside the Hurricane - nozzle (again)

- nozzle holder as best I could
- checked ignitor - works
- cleaned photodiode (again)

Now a little black smoke and then a lot of white smoke on startup. Runs for 5 seconds, then Flame Out.

Short of checking the photodiode, which is new since 2/2011, I'm looking for ideas.
Finding a technician versed in Hurricane problems within a reasonable distance of Anza Borrego CA seems a challenge.

Dick,

Mine was doing a similar thing and I couldn't put my finger on the problem until it quit working completely. Replaced the photodiode, fuel pump, ect....but continued to act up. It finally blew a fuse on my circuit board. ITR told me it was probably a bad circuit board. I disconnected all of the wires to it and put a new fuse in it and reconnected the wires one at a time until it blew again. It was in the igniter circuit but the igniter would start glowing then it would blow. I pulled out the cotter pin that holds the igniter in place and examined the igniter. The retaining pin caused a short in the wire that wasn't apparent to the naked eye due to the insulation on the wire.
If you haven't tried a new igniter you might want to get a new one and try it because even if it not bad it's not a bad idea to have a spare on hand as when mine failed the temperature was in the single digits.

Dick, if you're confident that the ignitor is good, then maybe look at the photo diode. Not sure how to check that. As suggested, It might be a good idea to call ITR. I carry a spare ignitor and thinking I should get a spare photo diode.

Up-date 2 : Hopefully the last for a while

Talked with ITR tech support (Jess) frequently for 2 days and did the checks they suggested.
We were not much wiser after that, other than: - at first no/not enough fuel was delivered to the nozzle. Symptom: no smoke or white smoke.
- then, after taking many things apart for the umpteenth time, too much fuel was delivered resulting in black smoke and a flame down to the ground when taking the exhaust off.
Very impressive when dark outside. Not the type of thing a fancy campground (or my insurance) will put up with for long.

At Jess's suggestion the decision was made to purchase a 5-year service kit (nozzle, nozzle filter, nozzle o-ring, flame detector, igniter). I also decided to buy a new regulator. Because of the fuel delivery changes I did not trust it.

UPS over-night + Christmas meant arrival today.
Put in the 5-year kit: still a lot of black smoke but no flame-out.
Replaced the regulator with a new one: runs perfectly.
The coming days will tell if all is well.

Many thanks to all who responded to our plight. It sure helped in getting the problem solved.

Best wishes for a great 2014.
Dick

Dick, just to give you hope, my CO45 now has well over 2,000 hours. It malfunctioned, smoked, etc. when I first got it 7 years ago. Replaced the fuel pump with the updated one then. Since then, flawless. I clean it once a year. The ignitor crumbled and was replaced. That is it. Rich 2002 Magna

Dick,

Which regulator are you refering to? Is it the fuel solenoid? Sounds like something I might want in my spares kit. TIA LARRY 03 ALLURE 30856

Larry,

As far as I know there is only one fuel regulator. It sits in the lower RH corner of the unit when you take the large side cover off. The fuel line from the fuel pump runs directly to it.
Looks like a square block of aluminium with a large hole in the middle.

The part # is 18001 and the cost was $100

The fuel solenoid is situated after the regulator and is located on the burner block. I took mine apart - you can unscrew the round electrical part from the base after disconnecting the 2 wires - , picked out some dirt, put it back together.

I just went through this with black smoke and flame out. Replaced The air compressor fan and all works fine. Jess with Itr suggested replacing the both the high limit and the burner after 13 yrs so ordered and will replace when I get south to warm. Leaving Oregon tomorrow. Yea. Hope you have smooth travels.
