@ March 9, 2014 4:56 PM in residential split system shuts down due to overheatingCould be a dirty condenser coil. It may also be low on refrigerant. Most newer outdoor unit 10 years or so have single row condenser coil and all you need is hose pressure and no chems are needed. Some older units have a split cond. coil and you need to remove the top of the unit and clean between the coils.
@ March 9, 2014 4:50 PM in converting from oil furnace air heat to heat pump with furnace as my back-upMaking your life way to difficult. Since you already have a lennox furnace stick with a lennox heat pump. If you do not currently have a variable speed blower stick with a single speed HP.You will most likly need to run a new low voltage wire to both the outdoor unit and the indoor tstat. Carrier makes a two wire indoor stat that will work with your old and new Lennox equipment.

@ March 5, 2014 11:21 PM in Burnham recall?Three recent boiler recalls all for pressure switch fails to shut down boiler. Burnham was not one of them. US Boiler, New York, and Crown boiler.
@ March 5, 2014 10:51 PM in Help needed on flame rollout switch keeping trippingThe pressure switch is sticking and not opening when the blower shuts off, hence the roll out.
@ March 5, 2014 10:39 PM in Hydronic off new DHW for BasementMakes a water heater with a space heating loop through a internal heat exchanger. Model # c-dw2-504t10fbn. I'm sure others make them as well.
@ February 25, 2014 10:50 PM in Coil Material Opinions:The fan moved the air not the duct.
@ February 25, 2014 10:38 PM in Janitrol Automatic pilotHave a thermocouple attached to it? If it does you can still get a BASO control.
@ February 25, 2014 10:36 PM in multiple furnaces going off on flu limetOr a business? Sounds like you have a sever negative pressure in the space.
@ February 23, 2014 12:59 PM in Tim; New IFGC QuestionI got from Lennox.
Dear Lennox Partners,
Please review the attached article from the WSSC Regulatory Services Group about Chimney Vent Restrictions taking affect December 1st in Maryland. This will restrict the use if not totally eliminate the use of Chimney Adaptor Kits for 80% Furnace installations and require a Chimney Liner instead which will likely add $1,200 to $2,500 to the cost of the job.
Please contact the WSSC Regulatory Services Group for clarification.
Attached was a PDF file That I can't copy and paste here because I don't know how. But it listed section 504.2.9 and table 504.3 and the 7 times area rule. My gut feeling is they are trying to get rid of 80% furnaces all together
@ February 22, 2014 5:05 PM in Tim; New IFGC QuestionSource was my Lennox distributor. They have basically stopped stocking the kits. I'm in the Washington DC area and I contacted my local code enforcement [WSSC] and was told they kits are only allowed on interior chimneys. I have used them on all chimneys in the past. I have a customer who refuses to believe me when I tell her she has to line her chimney. She says she hasn't heard of that. I ask her what codes she has heard of and she didn't have a answer for that, but still doesn't believe me.My local enforcers say it is new and went into effect on Nov. !st last year.

@ February 22, 2014 9:13 AM in Tim; New IFGC QuestionIFGC on chimney friendly kits. Anybody have a copy of those sections. I'm told they are no longer acceptable on exterior chimneys

@ February 21, 2014 5:05 PM in Soundproofing a boiler roomOf noise? What kind of boiler. I installed a Buderus atmospheric last week and found it to be nice and quite.
@ February 19, 2014 9:38 PM in Hydronic Air Handler in A Condo IssuesFan speed should lower the discharge temp which should make for a longer run cycle. I guess I would start by lowering the fan speed and that should quite the unit down
@ February 19, 2014 9:23 PM in Alpine Gas Boiler Venting ProblemBlue flame? Never seen a blue flame on a oil burner.
@ February 16, 2014 5:32 PM in Automatic vent dampenerWith tinman. Most of those dampers have 5 wires. Ground, 24v open and 24v close. The other two are the wires you need to jumper. Look at the motor and eliminate the ones going to the motor and the other two are what you want. But as you know be sure it all goes off when you shut it down at the stat.
@ February 11, 2014 8:09 PM in Condenser changeWas probably stuck some where. Why was the unit changed out? Was it a leaker was the system full of moisture? Maybe some crud in the piston and it shot into the coil. If it ain't broke now forget about it.
