@ December 19, 2013 9:46 AM in Combustion TestingTim, It seems that most manufacturers tell you to take combustion readings at full fire. Is there a reason for this? Lets say that you have a over sized mod con boiler and at max water temperature it is only firing at 50%. Wouldn't this be an appropriate level to take combustion readings? Thanks for any incite you can give me. Tom
@ November 15, 2013 1:30 PM in Dunkirk Quantum 90 Boiler EXCESS PRESSUREIt sounds like to me like that the pressure relief valve is doing its job by relieving excess pressure. These things normally don't start leaking by themselves if left alone. Generally just the opposite is true where they seize up. Yes, the expansion tank is likely a suspect but so are many other things that could cause excess pressure. Running a boiler with a known defect and letting a safety device save the day for you is not a good idea. You need to find a pro fast.

@ October 20, 2013 10:54 AM in Dangerous Condition??Is the horizontal section of flue pipe OK - or should there be a upward pitch to it?
@ January 12, 2013 12:57 PM in Lochinvar Knight Boiler "Lockout Fan Speed"Just curious - what was the solution to this problem?
@ April 10, 2012 9:02 AM in Patching hole in chimneyAfter removing a 4 or 6 inch galv flue pipe from a chimney what is the best method to patch up the hole if another appliance is not going to be connected at that point. Assume that the furnace and hot water heater will remain connected at a point lower than the removed flu pipe.
@ November 17, 2011 9:37 PM in knightly cleaningIronman thanks for the reply. If I understand correctly the rain cap would not be used anymore because it would not fit over the coupling. Also, has rodent entry been a common problem with using concentric vents ? I kind of suspect it is since you had a answer for the problem.
@ November 16, 2011 6:54 PM in knightly cleaningThis past summer I also cleaned my Knight and it was very similar to your pictures. This fall when I first turned on the boiler I got a surprise as it shut down on low fan speed and the fan made an abnormal noise. What I found was a mouse stuck in the fan impeller. I am using a concentric vent and would like to prevent this from happening again. Anybody have any ideas on how to screen off the intake on a concentric vent?

Release # 98-072 CPSC, Manufacturers Announce Recall Program to Replace Vent Pipes on Home Heating Systems
WASHINGTON, D.C. - In a landmark action, virtually the entire furnace and boiler industry together with the manufacturers of high-temperature plastic vent (HTPV) pipes have joined with the U.S. Consumer Product Safety Commission (CPSC) to announce a recall program. This program will replace, free of charge, an estimated 250,000 HTPV pipe systems attached to gas or propane furnaces or boilers in consumers' homes. The HTPV pipes could crack or separate at the joints and leak carbon monoxide (CO), presenting a deadly threat to consumers.
CO is a colorless, odorless gas produced by incomplete burning of carbon-based fuel, including natural gas and propane. The initial symptoms of CO poisoning are similar to the flu, and may include dizziness, fatigue, headache, nausea and irregular breathing. High-level exposure to CO can cause death.
To determine whether they have HTPV pipe systems that are subject to this program, consumers should first check the vent pipes attached to their natural gas or propane furnaces or boilers. Vent pipes subject to this recall program can be identified as follows: the vent pipes are plastic; the vent pipes are colored gray or black; and the vent pipes have the names "Plexvent ," "Plexvent II" or "Ultravent " stamped on the vent pipe or printed on stickers placed on pieces used to connect the vent pipes together. Consumers should now check the location of these vent pipes. For furnaces, only HTPV systems that have vent pipes that go through the sidewalls of structures (horizontal systems) are subject to this program. For boilers, all HTPV systems are subject to this program. Other plastic vent pipes, such as white PVC or CPVC, are not involved in this program.
After checking the vent pipes, consumers should call the special toll-free number (800) 758-3688, available between 7 a.m. and 11 p.m. EST seven days a week, to verify that their HTPV pipe systems are subject to this recall program. Consumers with eligible systems will receive new, professionally installed venting systems free of charge. Additionally, consumers who already have replaced their HTPV pipe systems may be eligible for reimbursement for some or all of the replacement costs.
The program came about as a result of mediation among 27 participants manufacturers of HTPV pipes and manufacturers of natural gas or propane-fired boilers and mid-efficiency furnaces. This is the first time that CPSC has used a mediator to bring together all segments of an industry to implement a program for the benefit of consumers.
All consumers should have their fuel-burning appliances inspected each year to check for cracks or separations in the vents that could allow CO to leak into the home. In addition, CPSC recommends that every home should have at least one CO detector that meets the requirements of the most recent Underwriters Laboratories 2034 standard or International Approval Services 6-96 standard.
The following lists the manufacturers participating in this program.
Armstrong Air Conditioning Inc.
Bard Manufacturing Co.
Crown Boiler Co.
The Ducane Co. Inc.
Dunkirk Radiator Corp.
Evcon Industries Inc.
Hart & Cooley Inc.
Heat Controller Inc.
International Comfort Prod. Corp.(USA)

@ January 19, 2011 9:39 PM in Condensation in Ignition IntakeIf you are getting that much water in the intake air piping I would suspect that you may have a leak in the concentric vent where some of the exhaust is being sucked into the intake. To prove this test some of the water you are collecting in the trap and see if it is acidic with some litmus paper. In any event an exhaust leak is not good and who knows where else the exhaust is leaking to. Make sure you have some CO detectors in your home and if it is in fact leak get it repaired ASAP.
@ January 8, 2011 11:01 AM in An Article On CO AlarmsI just looked at the instructions for my First Alert CO monitor and it tells you to mount it on a wall EXCEPT within 4 inches where the ceiling meets the wall. I could find no lower limit for mounting it on a wall in the instructions. This infers to me that I could mount it on the wall near the floor but not near the ceiling. I wonder what instructions another CO manufacturer has.
@ November 25, 2010 10:07 PM in reflector in atticInsulation will generally have a vapor barrier made of foil and this should be facing down to the heated area. If you were to add additional insulation it should be pure insulation with no foil. I am afraid by you adding foil on top of the insulation it will actually be worse insulation wise because you will trap moisture. I have seen many instances where the installer incorrectly placed the foil side up thus allowing trapped moisture from the heated area to collect in the insulation and thus decreasing its R value.
@ July 23, 2010 8:18 AM in Referral FeesWhen you advertise you could easily spend 500 dollars to get customers. Also, on the retail side there is all kind of "refer a friend" promotions where a customer can get cash back for referrals. I have seen these for car dealers, Internet providers, home builders, and a host of others. So far the posts on this topic seems to imply that referral fees are not ethical - but I wonder.
@ March 28, 2010 9:33 AM in Modulating is it efficient?I wonder how much of this data has been done by the boiler manufacturers. In a early version of the Knight Mod-Con brochure they included a graph which showed the efficiency of their KBN boiler as a function of both the return water temperature from 50F to 160F, and also the boiler firing rate ranging from 20% to 100%. For some reason this graph is not in their latest publications.
@ February 24, 2010 9:01 AM in Ameri-therm Vent DamperDoes anyone remember the Ameri-therm vent damper? These were a mechanical device that consisted of a stainless steel housing and four quadrants of a bi-metal inside. When the hot flu gases from the furnace or hot water heater reached the bi-metal the flu opened and allowed the gases up the chimney. Since there was no permissive between the appliance and the vent damper this always seemed questionable to me.
1. Are these dampers still made?
2. Are they still legal or restricted by code?
3. Does anyone know of a problem with one where a fatality occured?
4. If you seen one on a furnace you serviced what would you do?
5. How about on a hot water heater that you did not service?
@ February 5, 2010 7:25 PM in 2 hours?Dont forget that there also had to be time spent in troubleshooting and diagnosing the problem. I think that you are only looking at the replacement and installation time.
@ January 3, 2010 8:44 AM in condensation on windowsThe first thing to check is if the excess moisture is coming from a cracked heat exchanger or venting problem of your furnace.
@ December 28, 2009 10:14 AM in corrosion from condensateI have also seen the condensate make pit like tracks in a concrete floor. The condensate seems to disolve the cement and what you see is a stone surface in a track below the level of the good cement. Very unsightly. I am sure that this disolved cement must be beginning to plug something up.
@ December 22, 2009 7:43 PM in PVC Concentric Vent TerminationMark, I hear you, but this is directly from the instructions of the Concentric vent:
"Follow the furnace installation instructions for locating the furnace, clearances, operation and safety procedures. Use these instructions for installation of the concentric vent termination kit"
@ December 22, 2009 10:21 AM in PVC Concentric Vent TerminationGood point. Then too it does not have to be either up or down - the vent can be rotated at any angle between up or down. I think that the orientation of the vent may make more sense to position it to reduce the fittings necessary for installation. The main problem of course is that two complete opposite instructions are given. So much for following directions!
@ December 21, 2009 11:10 AM in PVC Concentric Vent TerminationThanks for the replies. Thats great that you showed a picture of the concentric vent. This is the same picture that comes with the instructions for the concentric vent. My concern is with the left side of the concentric vent where it shows the leg for the intake air facing downward. In the instructions for the Knight they show the leg for the intake air facing upwards. There is also a note that says: "IMPORTANT: Intake leg must be facing up" This is shown on page 23 of the Knight installation and operation manual. My question is why does it make a difference, and why are there two different instructions given for the same thing.
