Re: Lochinvar WBN080 lockout

Pin fitment or the the pressure the female part of the connector exerts on the male pin needs to be adequate. Also poor crimps or crimps that the wire has oxidized or corroded inside of the crimp are also suspects. A vendor like Digikey.com or Mouser.com may have the connectors and pins, matching it up correctly may prove time consuming, there are many connectors and often subtle differences.

Do any of the connectors show signs of discoloration due to heating (loose connection) ? In the event of a poor connection the boiler may shut down quickly so connector body heating may not be evident.

Re: Lochinvar WBN080 lockout

With the WBN080 wiring documents I did not see a pressure sensor.

Re: Lochinvar WBN080 lockout

I would call Lochinvar tech support tomorrow morning and ask them what the E01 code is for sure as It is not in manual. Odd.

Re: Possible to wire furnace fan to thermostat controlling a boiler?

Ed, had a few minutes and re wired everything.
r from furnace to rc tstat

G from furnace to g tstat

C from furnace to c tstat

R from boiler to rh tstat

W from boiler to w tstat

I can now turn on the fan and control boiler separately through my ecobee.

Thanks again for your help!!

Re: EK System 2000 hot water suddenly too hot?

I think all of the bases have been covered here. Based on the quick transition to hotter water, I would suspect that either a) something partially blocked the plate heat exchanger (maybe a piece of the degraded anode rod), or b) the check valve is not working and the circulator failed (gravity flow on the domestic side will heat the tank if the check valve is not working). For reference, we've found that IR guns are notoriously inaccurate for these types of diagnostics.

I know that @Robertw previously gave contact information for Brian Kiernan and our office for further support as well. Interested in your findings.

Thank you,

Re: Venting into a chimney

In MA if I go out the side of the house I will need to include a sign on the side of the house, and hardwired C0-2 detectors on each floor of the house (costly add on)…. maybe its cheaper to drop the pipe down the chimney then.

Re: Venting into a chimney

"chimney" being rather vague… I'd get a reliable chimney sweep in to clean and evaluate the flue or flues and the structural condition of the chimney. It might need work. Might not. Might need a liner. Might not. Might be big enough. Might not…

Also you need to know exactly what the venting requirements for that boiler are.

Re: Venting into a chimney

Consensus doesn’t matter. The fact is that you cannot vent a condensing boiler into a masonry or metal chimney.

The manufacturer’s installation instructions give detailed info on how the appliance must be vented and it’s mandatory that they be followed.

Re: Venting into a chimney

but you could use the unused chimney as a chase to run the correct flue.

Re: Venting into a chimney

I couldn't find that model number so I could reference the listed instructions. However, if this is a condensing boiler, which I believe it is, then the venting must be listed to UL 1738 for positive vent pressure. That would probably mean a polypropylene plastic liner. Masonry chimneys are not approved for positive vent pressure. Most stainless liners are Not listed to 1738 for positive pressure or condensing.
