@ December 13, 2013 7:07 PM in What is the definition ofthink about it this way, Make up air is the air required to replace air removed by mechanical exhausting. This is not necessarily combustion air as more air in addition to make up air may be needed to sustain combustion on oil and gas fired appliances. This is where we get into the two opening rules etc as air for combustion.
The make up air may be replaced mechanically or it may be an opening sized a certain size based on appliance BTU and CFM. A gas dryer is an example that may need makeup air.
@ December 13, 2013 7:01 PM in What doesMr. Harper, you are correct. The standard method still remains in effect which is the 50 cubic feet of volume per 1,000 BTU's. The importance of KAIR is that it recognizes the difference in combustion air volume requirements between the two appliance types, fan-assisted appliances and other than fan-assisted appliances which is "all other appliances". The amount of required indoor air for each type of equipment is different due to the different amounts of dilution air each requires. Typical gas-fired natural draft (draft hood) appliances require 21 cubic feet of air for every cubic foot (1,000 BTU's) of gas burned. Modern fan assisted combustion systems do not need dilution air (no draft hood), they still require approximately 15 cubic feet of air for each cubic foot of gas burned. The final proof of adequate air is the combustion test.

What does it mean to heating systems?
Does it really matter?

Does adjusting primary air change the analyzer readings?

@ December 11, 2013 7:47 PM in New install: choose propane or oil?Part-Cargo of Propane Sells for $2.35/gal at Providence
A robust export market, declining U.S. inventories, logistical supply constraints and colder temperatures have converged to heighten domestic propane demand and boost propane prices at the onset of winter. And that has resulted in suppliers reaching outside North America to bring in additional supplies.
DCP Midstream Partners last week procured a part-cargo of propane slated for first-half January delivery into the Providence, R.I., NGL terminal. It plans to sell that cargo at $2.35/gal -- more than $1.00/gal over today's Mt. Belvieu anys price for December spot propane, sources tell OPIS.
It's thought that a multi-state marketer has agreed to purchase from DCP the bulk of the barrels -- up to six million gallons -- the minimum volume needed to base load a ship. DCP will make the remaining supply available to other buyers, according to reports.
The Providence terminal is owned by Enterprise Products but DCP holds a contract to market propane out of the 17-million gallon facility. DCP last sold a cargo of propane out of the terminal in April 2013 at $1.55/gal. It had gauged interest in a second ship since then, offering propane in October at $1.85/gal, then $1.95/gal, and then at $2.19/gal with no initial takers, sources said.
But now that more frigid weather is in play, there's no question that buyers will pay up for propane, rather than run out.
Spot prices continued to escalate at Mt. Belvieu this week, striking 22-month highs on Tuesday morning, with TET/non-TET deals worked from $1.3075- $1.3175/gal. In the Conway market, spot propane prices soared to $1.3475- $1.37125/gal.
U.S. inventories bear close watching this winter. Propane (and propylene) supplies are 18 million bbl below last year's levels, as of the last weekly inventory report from the Department of Energy. The year-on-year decline is attributed to increased propane exports out of the U.S. Gulf Coast, and a robust fall crop-drying season in the Midwest.
In addition, there are lingering logistical concerns that could potentially see some regions shortchanged of needed propane supply this winter. Shippers on Enterprise's TE Products pipeline system expect that allocations on the line could persist off and on through the winter now that the firm is reversing one of the two lines on its TE system for ethane service. That means that long haul shippers seeking to move propane from the Gulf Coast to the Northeast will have just one line to use on the TE system, forcing them to seek alternative means of moving propane to customers.
Meanwhile, railcar supply is tight in both U.S. markets and in Canada, and that is limiting deliveries of propane to retailers.
"This is going to be a tough winter," predicted one source as back-to-back winter snowstorms hit the Northeast. "There are going to be some dealers that run out of product."

@ December 11, 2013 7:35 PM in Gas Conversion Help.right back at you. Why won't you identify yourself, it is the practice on this forum to make ourselves known.
As to your point about manufacturers I have communicated with one on several occasions, that being Burnham. They do not authorize any Burnham oil system being converted to gas using a power burner. That we all accept and also the voiding of warranty is also accepted. That does not however mean that the boiler can not be converted, it is a matter of choice on the part of the homeowner and the contractor. Here locally we do not have any trouble with inspectors approving conversions as long as Z21.8 (are you familiar with that publication) is followed and the burner manufacturers instructions are carried out.
I have found in sitting down with inspectors and taking the time to explain the conversion process they are not opposed to allowing it.
I realize there is a lot of genuine concern in the oil industry about the recent loss of customers to natural gas, perhaps you may be associated with that industry. The latest Indoor Comfort Magazine version discusses some of the great things that are happening with oil equipment. It is my hope that oil will make a comeback. That is why on all my conversions I leave the old oil burner there. The price of natural gas is expected to go up 13% this winter with oil holding steady. Propane is in trouble with the inability to have product available especially here in the north east.
Why not identify yourself and give us your personal opinion about the fact that as we speak there are perhaps some new power gas conversion burners coming out.
Look at the Carlin Applications Guide for all the boilers they have tested and recommend their burners for use with those boilers.
@ December 11, 2013 1:56 PM in Electronic low water cut offLow Water Cutoff and I assume it is on a boiler not a furnace. Does the "new" LWCO have an outdoor reset function in addition to low water function?
@ December 10, 2013 7:53 PM in Weil-McLain CGa series 2 LWCO Electrical connectionfor an older version of the CGA and it requires LWCO to be wired in series with the Water Temperature Limit Switch, look for yellow wire going from limit to the roll-out switch and wire it in between those two controls.
@ December 10, 2013 7:49 PM in Weil-McLain CGa series 2 LWCO Electrical connectionon the board is it 1107-2?
@ December 10, 2013 7:45 PM in Weil McLain Model 1107-2 Control, Power and flame light flashingIntegrated Boiler Control I would have someone pull the pilot and clean the pilot orifice and also the flame rod. You may not be generating sufficient microamps when the pilot is on.
If the pilot is not getting any spark at all or will not light at all then it may be the board.
The part number for the board is Weil-McLain #511-330-079 if you check the yellow pages or google in your area for local Weil-McLain dealers. F.W. Webb handles Weil-McLain in a lot of areas.
@ December 10, 2013 7:28 PM in Burnham Revolution RV4NSL-L2 no ignitionterminal B2 on the L8148 Relay. Place the other lead on B2, when there is a call for heat do you have 24 volts? Is the combustion air blower running?
When the CAB comes on it should cause the SPDT pressure switch to make N.O. and send 24 volts to the SmartValve. Is this happening when it will not run?
If it is not coming on every time you will need to check with a digital manometer across the pressure switch hoses. If you have the manual for the boiler the procedure for that is found on page 76 in the manual.
@ December 9, 2013 2:08 PM in Old raypackit could be plugged up internally which means it needs serviced and perhaps cleaned.
@ December 9, 2013 2:00 PM in considering replacement for old millivolt thermostatmatched up to the self generating "Powerpile" gas valve you have.
Anyone selling you a TS86 with an adjustable anticipator is ripping you off.
The Robertshaw and White Rodgers thermostats you listed are compatible with powerpile systems.
Any thermostat you install must be set up for use with millivolts if not you will have more problems not the least of which would be a high millivolt drop across the thermostat giving you no heat.
@ December 9, 2013 1:45 PM in Need Help Troubleshooting High Limit Switch on Gas Boilerhigh limit aquastat from the boiler insert the capillary bulb under the cold water faucet and connect a ohm meter to the wire contacts on the aquastat with the switch set at 180 it should show continuity. Now put a kettle on the stove stick the capillary bulb in the water and turn on the burner, if you have a cooking thermometer stick in the kettle next to the capillary, at around 180 you should loose continuity on the meter if you do the limit is okay and I would then suspect the well.
@ December 9, 2013 1:35 PM in Weil McLain vent pipe freezing side wallis required to use AL-294C stainless steel for venting and it does require a condensate tubing of the bottom of the boiler to a drain.
This is a Category III boiler which means it is not designed to be a condensing boiler but may have condensate in the vent and that requires being addressed.
Now here is the real issue a lot of those Series 2 units used a plastic vent either Plexco Plexvent or Hart & Cooley Ultravent one is a gray plastic pipe the other a black plastic pipe with see through (translucent) fitting. Both of those plastic vents are now a code violation and had a recall back about 15 years ago or so and they need to be removed and replaced with stainless steel AL-294C venting.
@ December 9, 2013 1:20 PM in Removing furnace from gas ventand look for any condensation at the draft hood if there is no condensing and the water heater is drafting (homeowner test with some smoke at the draft hood skirt and see if it is sucking the smoke in or blowing it out, sucking in is good) If you are a pro do you have a draft gauge or combustion analyzer?
How long is the vent connector?
@ December 9, 2013 1:13 PM in Burnham Revolution RV4NSL-L2 no ignitionHoneywell Smart Valve for an ignition system. Does the boiler have an L8148E relay? If so when the thermostat calls do you have 24 volts at B! and B2 on the relay?
Do you have circulators or do you have two zone valves and an single circulator? If zone valves what make and number are they?
@ December 9, 2013 12:53 PM in See-through or dual room natural gas fireplaceGeneral Controls Pilot you are describing. It is available from White Rodgers as a replacement General Control adaptation. I wish you well with what ever you decide to replace your existing wall furnace with.
@ December 7, 2013 8:00 PM in in need of 6 short inshot burners.that were not designed for the equipment. Burner design is a very critical part of proper operation of gas and oil systems. In some cases you could be developing a dangerous situation.
