          I have a 25 year old boiler and after troubleshooting, found the Aquastat relay and gas valve were shot. I searched locally and found supply houses were not helpful as the model was old and had been replaced and I could not get a straight answer. I contacted Pex Supply after doing an online search and they cheerfully gave me the correct model replacement and the best price I could find online!! The only complaint was that the online chat to get the info on a replacement took nearly 3 days to hear back from. In the meantime I was without heat, so on day 2 with no response, I chose to call their toll free # and got an immediate answer. Thanks Pex!!!!

                            Original item received and installed, worked for two days and failed. Called Pexsupply, they sent me out a replacement same day, no questions, and sent me a UPS pickup slip for the return. Credit received immediately. Great Service. Will absolutely buy from again.

                                        Perfect fit. Went in smoothly and without difficulty. The key is to mark all connections on the old unit so they can be duplicated on the new. Turned a $800to $1,000 professional job into a DYI job for less than $200 including a motor-to-pump coupling replacement.

                                                          This is a standard boiler relay, but the first one I got was defective. pexsupply was outstanding to deal with for replacing it. There was a live customer service person who spoke English (sorry to the call centers overseas) and I had a replacement in 2 days as will as all return documents the day I called. OUTSTANDING service pexsupply I have already recommended you to others.

Crank that room thermostat as far as it will go and using a reliable temperature analyzer, measure the temperature of the line leaving the boiler. Set the control to shut off between 180 and 200*. If you get water seeping from your relief valve, you've set it too high.

Apparently this is the direct replacement since the L8148E is discontinued (according to the Honeywell web site). The boiler comes with the automatic vent damper. My HVAC guy replaced the Aquastat and connected the wires just like the old one. However the boiler did not work properly. Even when the thermostat did not call for heat the boiler would still turn on. After some trouble shooting, my HVAC guy told me that it appears that the new Relay L8148J must have some internal ground, and the ground (green wire) that goes from the burner (screwed on the burner) to the GDN (Burner) on the Module (black box on the boiler) was causing this problem. When he disconnected the green wire (GDN burner) everything seems to work just fine. Is this true? Do the L8148J have some internal grounding that would cause this problem.

                                                                        The person in Colorado (see above) appears to have the same problem.

It sounds like some temperature setting may need to be changed.
