@ March 6, 2014 4:29 PM in Carlin Gas Conversion or new oil tank?candidate for the new Carlin EZ Pro conversion burner, have it converted just make sure whoever does it has experience with gas conversion burners.
@ March 6, 2014 4:24 PM in Help needed on flame rollout switch keeping trippingthere is a flap between the transition (RED Hose) and the flue collector (WHITE Hose). If that flap is not working the pressure switch will not work properly and you will get poor combustion due to restriction caused by the flap. It needs the top removed from the flue collector and a cleaning and a check of the flap to see if it needs replaced. This is a very typical problem with the HE and VHE boilers with this flap. This by the way was the beginning of a design system to reclaim some of the heat lost up the flue in the flue collector. There is a copper coil in the collector which is part of the boiler system water tubing.

@ March 4, 2014 9:38 PM in Ultra 155I and O manual is usually the best to follow. Why are you asking is there a problem?
@ March 4, 2014 9:36 PM in WM GV90+ Backfiringcleaned and serviced since it was installed? Has a combustion analysis been done?
Are there any lights flashing on the United Technology 1013-200 control?
@ March 3, 2014 10:10 PM in Honeywell Zone Valve V8043 wiringWire the hot lead (R) from the transformer to one yellow lead, wire the other yellow lead to one thermostat lead, A series circuit and it does not matter which motor lead goes to which connection. The two red leads (end switch) go to "T T" on the relay. It does not matter which red goes to which "T".
Thanks Pughie just one too many sentences.

@ March 2, 2014 8:02 PM in Cgm-4 boilerWe look forward to helping you here.
@ March 2, 2014 8:00 PM in Cgm-4 boileron the boiler? Did you take millivolt readings on the powerpile system? If so what were your readings? What was the number of the valve you removed and what are the numbers of the one you installed?
@ February 28, 2014 9:29 PM in Gas firegas valves used on either vented or unvented heaters, unvented have to have an oxygen depletion safety device, that can be set for hi-fire or low fire. Get in touch with your local fireplace store they can set you up with just about anything in the way of vented or unvented.
@ February 28, 2014 9:18 PM in Reducing mod/com output with multiple stage gas valvegas valves that are what I would call multi stage in the real sense as the turn down ratios are defined by how low the firing rate can go based on burner design and port loading with the varying speed of the inducer. This falls under a standard which has not been changed here in the US, at least not to my knowledge. It has to do with the minimum firing rate for safe ignition based on using flame rectification as a flame proving system.
@ February 28, 2014 12:03 PM in KANE 455 flue gas analyser...the 455 and 457 can be seen at www.jmwlimited.co.uk/kane_455_combustion_analyser.html
@ February 28, 2014 11:53 AM in KANE 455 flue gas analyser...have an oxygen sensor and a Carbon Monoxide sensor, some can be changed in the field. UEI offers one with a CO2 sensor but none of the others have a CO2 sensor. That is unless Icesailor has info on some new ones I do not know about. Most of the detectors sold today can be sensor changed and calibrated in the field without sending back to the factory.
I believe the Kane is a commercial industrial level tester but I will look it up to make sure.
@ February 26, 2014 8:45 PM in Janitrol Automatic pilotno longer available. You would have to d a complete changeover which is not cheap and requires someone with experience at doing such things. Sound like it is time to replace the old boiler.
@ February 26, 2014 5:01 PM in How many of you carrywall receptacle are probably more for convenience and will still work it just may take a little longer to alarm. Most of the over the counter detectors alarm at 70 PPM after 240 minutes which satisfies UL-2034. My detector I use alarms at 9 PPM immediately, much safer.
@ February 26, 2014 12:00 PM in How many of you carry60 degrees is .97 specific gravity as compared to air which is 1.0 SG. As the temperature goes down however CO may actually become slightly heavier than air. It brings me to something I teach my classes, CO will accumulate at typically mid point in a room. So the detectors should be at that point (sorry Massachusetts), I call it "head to bed" head standing up to bed lying down. I prefer for use in my home portable detectors like CO Experts 2014 or 2015. I can move them from room to room depending on what rooms are occupied especially at night on the night stand in the bedroom. I heat with a pellet stove so definitely one in the room about 25 feet from the stove.
The fact that CO and air are so close in SG makes CO even more dangerous. Your body will actually absorb CO faster and hold it longer than it will oxygen.
Education is the big thing get to Jim Davis classes or Bacharach and my 3 day combustion testing design equipment classes.

@ February 24, 2014 7:05 PM in How many of you carrya Personal Protective Equipment Carbon Monoxide detector?
What level of PPM does it go off at?
Should fire department first responders and police have detectors?
All this is really not necessary as you would quickly be able to tell if CO is present the minute you enter a dwelling as it would cause a headache, sore throat and you would know it was CO. What do you think about that statement.
Recent CO incidents have brought to question proper training, personal CO detection carried on your person, and police and fire personnel entering buildings and being over come.
Should public buildings be required to have CO detectors?
A wet kit Combustion Analyzer set up will pick up CO immediately and a zero smoke reading on a gas boiler would tell you if you had high levels of CO. What do you think about that statement?
On an oil boiler or furnace it is not necessary to have a wet kit (blue chemical) Fyrite for measuring oxygen? It is not necessary because we take an over-fire draft reading.
@ February 24, 2014 6:53 PM in Oil to GasA question has come up concerning licenses and also directly related required training.
Should someone who has an oil license for installation and service be required to get a gas license? What do you think about this?
If the oil license is okay for both oil and gas do you think the oil technician requires any training on installing, servicing and codes on gas?
A recent carbon monoxide incident has brought this to the surface and created somewhat of a stir.
@ February 23, 2014 3:30 PM in Tim; New IFGC Questionhas been in NFPA 54 National Fuel Gas Code and IFGC for several years now. It restricts the use of exposed or actually called Exterior Masonry Chimneys in certain climate zones. These are defined by Figure B-19 in the code book. The Maryland area is in zone as defined by table 504.3 (6b) as the 5 degree to 16 degree zone which will not allow the chimney to be used unless as a minimum it is 10 feet high with an internal area of 113 square inches and input to the chimney is 430,000 BTU's. THIS IS NOTHING NEW AND IT IS NOT A CHANGE TO THE CODE IT HAS BEEN AROUND FOR QUITE A WHILE. ALL WSSC IS DOING IS LETTING IT BE KNOWN THAT IT IS GOING TO BE ENFORCED.
HERE IS THE ARTICLE FROM WSSC:
Strict Enforcement of Outside Chimney Venting Restrictions
In most applications where space heating appliance(s) [furnaces and boilers] are served by an "outside" masonry chimney, the chimney will require the installation of a listed liner when any of the existing appliances served by the chimney are replaced. According to the sizing charts contained in the 2012 International Fuel Gas Code (IFGC), outside chimneys cannot be utilized "as is" unless a minimum of 300 - 400 Thousand Btu's are connected.
A water heater(s) may be connected to an outside chimney providing two conditions are met:
1.) There is not a space heating appliance connected;
2.) The internal cross sectional area of the chimney does not exceed seven (7) times the area of the smallest connected draft hood.
Refer to 2012 IFGC code section 504.2.9 and Tables 504.2(3) & 504.2(6) for single appliance venting; refer to code section504.3.20 and Tables 504.3(6a), 504.3(7a) & 504.3(6b), 504,3(7b) for multi appliance venting.
These IFGC code sections and tables have priority over less restrictive manufacturers installation instructions including those touted as having "chimney friendly”alternatives.
Important Safety Message- Be sure to remove all accumulations, each and every time, from the base of chimneys and vents (dirt pockets), prior to placing any equipment into service. This applies to all inside and outside chimneys, which qualify for continued use, as well as metal vent systems. Always check the integrity of the whole venting system!
This is a good thing as there are really too many problems now with appliances which can not generate enough Delta T temperature difference and lack of height along with exposure on three sides to the chimney. They will just not have adequate draft to be safe.
I do not think anyone is trying to get rid of equipment, they are coming to the realization that chimneys which once experienced 30 to 40% of the heat generated as flue loss when now reduced to 15 % or less will not operate.
