@ March 8, 2014 1:05 PM in Adjusting a Gas Controlyou can do as you would need a Combustion Analyzer to a test and then of course you have to understand what the readings on the tester mean.
Are you having any problems with the installation that we might otherwise be able to help you with?
@ March 8, 2014 1:01 PM in Carlin Gas Conversion or new oil tank?procedure to do a heat loss, then measure square feet of radiation and then look at what the oil guy was firing the unit at as far as nozzle size and pump pressure. That will bring us to a starting point as to input, then an accurate combustion test will allow you to fire the boiler at its maximum designed firing rate. This can then be adjusted by using the pressure regulator on the gas valve.
As for the lining on the chimney ANSI Z21.8 Procedures for the Installation of Gas Conversion Burners requires a liner with all conversions since 2002.
I've also been told that if the new conversion burner is within 95% of the BTUs of current oil burner than I can safely avoid lining the chimney. Does this sound correct? THAT RULE IS OUTDATED AND ANSI Z21.8 APPLIES.
@ March 7, 2014 1:24 PM in Help needed on flame rollout switch keeping trippingaffects the flue gas travel which in turn affects the chamber pressure and the extinction of the gas flame in time. The pressure switch works on differential pressure red hose to white hose with the flapper in between, the gas valve is directly controlled by the SPDT pressure switch making and breaking at the correct time other wise you have residual gas in the chamber with no air entrainment hence flame roll-out. The flue collector needs to be opened up and a professional who is familiar with the Weil McLain HE series to take a look at the flap.
@ March 7, 2014 1:18 PM in Adjusting a Gas Controlconversion burners you got an excellent service call and a good combustion analysis.
@ March 7, 2014 1:17 PM in Carlin Gas Conversion or new oil tank?The Wayne burners are not a good burner for that application as the flame pattern is too long and impingement is probable. You need a burner like the Carlin EZ with the shorter flame pattern and still giving adequate BTU to satisfy maximum firing rate.
@ March 7, 2014 1:10 PM in Carlin Gas Conversion or new oil tank?the boiler will probably last another 10 years with a Carlin EZ Pro the new Carlin Burner. I wish that the near boiler piping could be changed as copper is not a good idea on steam. All of the conversions I ever did required some refurbishing of the existing boiler, including perhaps a new fire box or at least a target wall in the chamber, removing the outside jacket and checking the sections for proper sealing, and in the case of steam making sure all the controls etc. worked and did not need any maintenance.
Part of the issue with replacing oil steam boilers with gas atmospheric steam is the efficiency is much lower do to high excess air requirements.
This boiler looks like it has been maintained and with some gasket replacement etc. it will go 10 more years.
I looked back at my records and I have converted 27 of these over the years. I took a chance and called one of the customers that had the conversion done eight years ago (Carlin G3B) and it is still running with good efficiency. The customer is more than happy with the long term operation. The only service has been to replace a hot surface igniter three years ago. The boiler is given annual maintenance by one of my trusted service companies here in this area.
@ March 6, 2014 4:31 PM in Adjusting a Gas Controlalways good to get a second opinion especially on adjusting a gas control.
@ 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.
