Lydia Hulette-- Sturgeon Lake, MN I read with fasination your posts. If your Munchkin isn't working properly, you have a right to be angry. However, that doesn't solve your problems. 1) "My old boiler used 90/gal of propane a month, now I use 200/gal/mo." Was the gas valve checked with a manometer for proper pressure? Was you Contender set up with a combustion analyzer? Did Troy spend a $1000 for one, and was it calibrated within the last 2 years? Is your Contender set up for propane and not nat gas. Propane has twice the BTUs (heating capacity) than nat gas. Running a nat gas boiler on propane will over heat the boiler and cause a ton of problems. (YOU MUST USE A COMBUSTION ANALYZER THAT IS RECENTLY CALIBRATED) 2) "the relief valve blew off and flooded under the foundation" The pressure relief valve is set to discharge boiler water at 30psi. Your boiler pressure should be 12-15 psi with cold water and goes up in temperature as the water heat up. It should be well under 30 psi. There are 4 things that can cause the pressure relief valve to discharge water. 1) a faulty pressure relief valve, 2) an increase in pressure due to over heating in the boiler, 3) street pressure 50 psi getting into the boiler(30 psi) (a faulty pressure regulating valve which is an ad-on). 4) a water logged expansion tank. Just look at the pressure gauge. It tells a story. Also, piping is a complicated issue as any Plumbing Engineer (a college degree) can tell you. Improper piping can cause issues that aren't easily discernible without training in plumbing engineering. I hope this helps. We got to fix those rolling eyes. Let us know what the solutions for your problems are.

Lydia ---- the relief valve blowing and dumping water all over the place is probably NOT caused by the boiler and probably by a bad expansion tank or pressure reducing valve. .... If you drove down a bad raod and got a flat tire would you blame the car manufacturer. Good luck with your lawsuit.

Ummmmmm *rolls eyes* I called Heat transfer inc. and was referred to an "authorized repairman" He came to my home along with the original installer from Ace. He has no idea either what the exact problem is. According to his "computer" the unit is working properly. But since the relief valve blew off and flooded under the foundation of my garage causing extensive damage and now my house floor is cracked also.... Yeah you bet your azzzz There will be a law suit. Imagine how much its going to cost to replace my concrete in my garage and my home <~~ if thats even possible. So if this is normal for a munchkin contender, I stand by my original statement. DON'T BY A MUNCHKIN CONTENDER. You might loose you home because of it.

I installed my own Munchkin Boiler 140, I am not a professional installer, read the installation manual from cover to cover. I would never exhaust a unit from the side of the building. Exhaust and intake are straight to the roof with a 32" separation. This Munchkin runs like a Swiss watch. Very fuel efficient. I build computers for a hobby, very impressed with the electronics of this unit. I truly believe the problem people are having, is with the installers.

What is the proper install to stop reversion and how to test?

CLEANING THE ELECTRODES--I use a Rotary Dremel like tool with a stainless steel wire wheel to clean the spark and rectifying electrode when I do servicing. This should be done on a yearly basis. These tools come from Harbor Freight and they are on the internet. Use only stainless steel wire brushes to clean them for best results. The stainless steel brushes are Item # 66129. DO NOT USE plumbers emery cloth or tape to clean them as they leave a deposit on the electrodes. I have used silicon carbide wet and dry sandpaper, tho. Only use stainless steel brushes with RydLyme or Simple Green lime remover to clean the heat exchanger. These are good tips. Get rid of those pesky F09s. (check the wiring harness, too.)

"T-90 works flawlessly"
I installed our Munchkin three years ago (following the instructions very carefully) and found it to be a flawless performer. I have done the annual maintenance on it myself (cleaning the coil of lime deposits - Rydlyme works best, but CLR also works). I could not be happier with its performance. Originally, I had one of our local HVAC companies come out and adjust the gas valve since we converted it from natural gas to L.P., and it has been saving us money on our heating bills since. We are using this to run our Hydronic Radiant in-floor heating system and our heating bills are 50% lower than our neighbors.

Dean of Saratoga Springs, NY--A very astute observation which should be helpful to others. Munchkin says that the gap should be 1/4", about 2 quarter placed together. My first experience with this was with a Heat-n-Glo fireplace. the electrode gap was about 1/8" and the spark would not ignite the gas. I expanded the electrode to about 1/4" and it worked like a charm. Why is this you ask? One would think that 1/8" gap would be easier for a spark to jump across than a wider gap and that's true. What happens is this. Electrical energy is built up in the ignition coil until it reaches a level where it can jump the gap. If the gap is at 1/8" the spark can jump the distance at a much lower voltage, let's say 8,000 volts. When the gap is increased to 1/4" the voltage will build up in the coil to 16,000 volts before it jumps the gap. A much hotter spark. If the gap is too wide, the energy developed in the coil cannot reach the voltage necessary to jump the gap and the field in the coil collapses which can destroy the insulation in the coil. Good Post, Dean.

"90 % of the errors are due to installation"
I wrote a review a while back on Munchkin. The biggest problem for the boilers are as follows. 1.) Vent too long,vent termination too close,or in a corner. 2.)Condensate drain not properly sloped or sized(1/2 inch ID will not work and plug up quickly due to debris from heat exchanger.I use 3/4 ID and a neutralizer(remember the condensate is acidic and will eat copper, cast drain pipe.) I recommend these boilers should be installed about 4 inches off the ground for better drainage. 3.)Gas piping and gas pressure.Ensure you design the gas pipe to no more than 1/2" pressure drop on natural gas and you will be safe. 4.) Hydronic piping must be done properly. Reverse return dose not work properly and over heats the boiler. Remember to pump(pump sizing is important) into the highest head(the boiler or/and heat exchangers). A Combustion analyzer must be used to ensure proper set up. NO!! the boiler display will not show you the CO AND CO2 READINGS . If you do not own an analyzer , please call a qualified technician that does. If you are willing to pay for my plane ticket and hotel room , food etc . I will be more than happy to help, but keep in mind it is a busy season . Good Luck !!

No I don't make a ton fixing Munchkin's ..... I make good honest money fixing other unqualified installers screw up's. ...................... Yes I install Munchkin's and don't have any problems with the ones I have installed and also don't have any problems with the ones others have installed that I have reinstalled. Again LYDIA ---- YOU had a guy from a HARDWARE STORE INSTALL YOUR BOILER.
