Re: Gas supply keeps cutting out

Flame detector's given up, mercury pressure developed from flame heating a small bulb and capillary pipe keeps gas flowing, they seem to fail over time. Not developing enough pressure and thus giving regulator a false flame out reading. dilonghi call them analysers. No fix - fir replacement prt

Re: Gas supply keeps cutting out

I'd be checking what the operating gas pressure is correct - when it's operating, not when it's stopped or off. My suspicion is that the gas pressure is incorrect & the regulator needs adjusting, or that the gas bottle is simply too small for the heater & can't evaporate enough gas to keep it going. You really need a gas expert to advise on site. Regards, Greg (Aussie gasfitter - too far to do house calls)

How to clean gas heaters

Agas heater is a device that uses liquefied gas for heating. Since it isconnected to a gas source, cleaning it is quite easy. Keeping the gasheater in good condition by cleaning it from time to time is importantto prolong its durability. Cleaning the gas heater regularly is alsoimportant from a safety perspective, because deposits in the flue, oranywhere else in the device, can sometimes lead to problems.

  1. If the gas furnace is not running, the power could be disconnected, the motor overloaded, or the gas supply insufficient. Check each of these components individually, ensuring the gas heater has sufficient power and that the motor is running (you will be able to hear if it is running when it kicks on). Check the gas reserves tank to ensure there is gas in it. If these systems function properly and you are still having difficulty, your heater may need to be cleaned or repaired.
  2. Cleaning
  3. If your heater is not heating properly, dirt in the gas lines--and especially the burner ports--could be the cause of the problem. First,disconnect the lever that connects the gas supply to the appliance. The burner ports are the parts that distribute the gas supply into the heater. They have to be cleaned with the help of a toothbrush or flask cleaner. The part called the burner access panel, which is located at the tank's lower part, may also have to be replaced if there is a dirt build up. This piece can be purchased at your local home improvement store and replaced according to the directions on the package.Generally, this should be replaced every two years.
  4. Filter
  5. If your heater is turning on and off repeatedly this could be caused by dirt in the filter or lack of lubrication in the motor or blower. Check your users manual to locate the filter (it is usually a large piece that slides in and out of your gas heater from the side), remove it after the gas has been turned off, and wipe off any excess dirt.Alternatively, you can replace the filter entirely rather inexpensively. Simply remove the filter, write down the model number and get a replacement from your local home improvement store.

Have a Rinnai XR26 . For a 2 person house and gas for water heating and cooking hob only, we use x1 45kg bottle of LPG every 3-4 weeks. 4 days of the week we are both away at work all day so it us just...

I'd really like to help you. But, you can not measure propane gas in kilograms. That's measure of weight, not liquid. The weight of the bottle, doesn't determine the liquid amount that the bottle or tank holds when it's 85% full.. Since Propane Gas is a liquid, I would need to know how many liters the bottle/ tank holds, to determine what your consumption is.

Please advise. Cheers...

My heater keeps blinking and a code on the top says 11...also ..if i unplug the unit while i wait for it to get fixed does the pilot light go out?

There is no pilot light on this model. An 11 error code tells us that there is no gas supply to the heater. Could be a bad gas valve, dirty igniter, gas got shut off somehow, dirty burner, etc... All you can do is make sure the filter is clean, a technician will need to open it up. Sorry.

My rinnai comes up with a code 11 when i try to start it. if i try it about ten times the main valve opens and runs fine. but untill that point it doesnt start. any ideas?

Mysolution relates only if you are on LPG/bottleg gas. I have had many problems with the gas regultor actually on the initial supply line near the bottles sticking. Error code 11 is usually simply a gas supply issue and not a fault with the heater itself. Just rule out that before you start messing with the heater itself. Causes inside the heater would be either gas valve (unlikely) or PCB. Both are not normally intermittent. Try running something else on gas if you have anything and then turn on the heater.

My gas heater regulator and some of the pipe frosts up and the gas seems to get blocked. The pilot light just flickers.It sometimes works for a couple of minutes. I took it back to the supplier who told me...

okay you carda was 4.5 kg bottle cannnot find what you have put on , at there site , so take it is the same bottle ? gas bottles will only fill so far ,you weigh the bottle say 10kg when empity you set the scales to 20 kg them fill the bottle when scale tips itis full , if you overfill a pressure relief kicks in letting out the over pressure so you can not over fill.. now freezing you could well have aleak on the lines or the reg is not working sticking open too much gas passing causing it to freeze up, this the best if can think of .

I have the Mr. Heater Big Buddy and it has been giving me trouble lately. After two years of flawless operation, the unit constantly shuts down, after only a few minutes of operation. I use a 20lb cylinder...

tough one doug, easy way is buy a new gas valve under red knob.
harder to try to fix old one.
the stopage of your mister heater is caused by the pilot lite going out
so what is causing the pilot lite to go out? that is the problem.

inspect the pilot lite and its gas supply tube all the way up to the main gas valve under the red knob control valve. unscrew the pilot lite gas supply line from the main gas control valve and clean out interior of gas supply line all the way through the pilot lite orfice to the open air. It must be totally clean, .like new, including the pilot
orface, in order to work properly.the least obstruction might deflect
or restrict the gas flow & cause poor or no opperation
when you unscrew the pilot lite gas supply line from the main gas valve,with a flashlight, look inside the hole, that the gas supply line was removed from.
It may be full of gunk that has to be removed for gas to flow properly. try blowing out with compressed air with a straw tipped blow gun. you may need carburator cleaner to loosen the gunk ,if gunk is present.
If you use carb. cleaner, it burns like gasoline, so make sure any carb cleaner is blowed of with compressed air or blotted up with facial tissue & totally dried up & removed before firing up mr heater, in order not to catch mr. heater on fire.

If a lot of gunk is in the outlet of the main gas supply valve,you will
need a pocket screwdriver,a paper clip and maybe a sewing needle in order to pick out the crud.
It must be totally clean inside, like new, in order to have a chance at working.
It may still not work if more crud is inside the main gas control valve where you can not get to clean it out.

if you reach the point where you decide to buy a new main gas control valve, first try disassembling your old main gas control valve and cleaning it out,like rebuilding a carb, and reassembling it.
If this works,you dont need to buy a new main gas control valve
and have saved 30.00 plus 12.95 shipping
if it dont work,all it cost you was time & angervation.and you still need to buy a new main gas control valve.
