The 86 was superseded by the 88 in 85. The CP# is a Weil glue on. They may be able to help.

L4079, & L408J Vaporstats are micro switched w/ stainless steel innards. With the death of mercury switches, there is no need to level the control case. Every steam pressure gage we use has brass or stainless wetted parts. The same pressure gage is used for steam, water, & other media.

shipped, or shown pigtails, on their 80,88,94,& LGB Boilers for years. Since none of the controls listed has a mercury switch: Why would you need a pigtail? The 63 is for steam or water. Both the 63 & 67 are low water cutoffs. The condensate pump could be controlled thru the #3 & #4 contacts on the 67's #11 switch. I wouldn't. A 150 is the way to go. That pre-supposes you are making up boiler water thru a boiler feed tank. If not. The 67 was probably connected to a 101 Feeder & the tank float switch operated the pump. Read all bold print on P. 23 of the I & O Manual before piping LWCOs. It matters.

@ December 31, 2008 4:15 PM in Should oil flame touch refractory?

draft commercial firebox boilers, it is not unusual to adjust hi fire so the flame tip just kisses the brick target wall & wisps upwards. If it hits it hard & the flame mushrooms in a circle; it's not adjusted properly.

@ December 31, 2008 2:29 PM in Man I am sick of some co. just trying to sell equipment

old lady whose heat died on a cold, icy, nite. The Plumber arrived, w/ his young daughter who sat w/ the lady drinking hot chocolate & eating cookies, while her father diagnosed the problem. Conclusion. Gas valve is dead. No replacements. Need new boiler. Big $$. Can rip old one out Saturday. Install new Monday. Sign here. She did. But. She had friends. They leaned on me. Slip/slid over. 160* on boiler. Replaced B&G Series 100 Coupler. Voila. Heat. Called Head Marketing Guy @ the gas utility. Told him what one of his preferred contractors had tried. His reply. "What am I supposed to do about it?" Click.

to the hurling water tank; the vacuum pump uses water in the tank for lubrication & vents the air, pulled from the system, out the vent on the hurling water tank. Most systems, we work with, operate in the 3 to 8" vacuum range. Sounds like a big pump on a system w/ many leaks.

@ September 26, 2008 10:33 AM in Oil burner too small?

You can make new gaskets from Kaowool Blanket. Near boiler piping is problematic. Like the men's room. No excuse for missing the target.

The 673

@ September 25, 2008 1:06 PM in Oil burner too small?

has a net rating of 325,600 btus per hour (1,355 sq ')steam. Your numbers indicate the boiler is undersized for the connected load. Properly insulated mains, & run outs, can mitigate the problem. Normally, the bare piping in the shower would not be a factor. However, it appears your situation is not normal. The SF, w/ proper mixing components, should do the job. Be sure to check those vertical flue passes.

In addition to

@ September 24, 2008 11:26 AM in Oil burner too small?

measuring the EDR, & firing as close as possible to that number, make sure the boiler is cleaned properly. The 73 Weil has top clean outs, for the vertical flue passes, that can only be accessed by removing the top boiler jacket panels. If the vertical portion of the sections is clogged, some techs will down-fire to compensate for high stack temps & over fire pressure, vs. negative over fire draft.

@ August 25, 2008 1:31 PM in Proper flue pipe size 3.5gph oil?

19-6 (not 19A) should have come w/ an 8" diameter flue collar. The 3, 4, & 5 were 7". The 19-7 was 9".

@ July 29, 2008 4:45 PM in power gas burners

How about boiler gross output, oil vs. natural gas? Ex: Weil 380 Oil Input 2.4 gph X 139,400 btus(NORA's #)= 335 mbh. Gross output 278 mbh. Eff'cy 83%. Gas Input 346 mbh. Gross output 278 mbh. Eff'cy 80.4%. Those numbers seem more definitive. Agree about residential & single stage power burners. Do the basics. Use a combustion analyzer (CO a must). Not a problem. Skip a step. Don't use an analyzer. Problems.

NOT ugly. It's a 1/3rd size version of the Chevy Panel Truck I wrestled around town in the late 1950's & early 60's. Up-sized a little would make it practical. Until then, I'll wait for the Transit Connect, or for Benz to bring back the short Sprinter.

@ May 13, 2008 11:20 AM in Where do we go from here?

is our collective effort." Not hardly. Government looks out to perpetuate and grow Government. You and I are only the cash cows/steers (bulls not allowed) that enable them. Do we really want Government (which is directly responsible for stopping known energy development) taking more of our $$, imposing more regulations, choosing which energy alternatives to pursue, & which political contributors will receive those development $$? Why not let what's left of market forces guide us in deciding our own energy future? Most of us will evolve and prosper. Those who chose not to should not be subsidized by the rest. Or, is that too Darwinian?

Here you go.

@ May 2, 2008 10:00 AM in Bio diesel gone bad

1. UL has NOT yet approved the use of the current ASTM Standard bio blends in oil burners. 2. Those burner manufacturers who have jumped the shark only approve B5 in their pieces. Most of the equipment has been tested for B5. 3. The fed'l gummint uses B20. Problems w/ above ground tanks & fuel lines. Turns to jello around 40*. Can't imagine using a B50 blend w/ outside tank. 4. High viscosity fuel should be compensated for w/ a smaller nozzle @ higher pump pressure to decrease droplet size. Bigger droplets, from high viscosity fuel, increase input above nozzle rating. 5. Wonder what the insurance folks would do if there was an incident concerning an oil fired appliance burning non-UL Approved fuel?
