Re: Mod-con Boilers and Outdoor Reset
Less benefit on low temperature systems.
But we are in the comfort business, so the valve could be in consistent operation, constant circulation possibility.

Re: Type of fixture ?
I’d guess delta or moen but hard to tell. You’ll have to remove cartridge to see what you need.
Steps to remove:
- Shut off water
- Pop the plastic trim off the control handle
- Remove center screw and control knob
- From there you should be able to remove face plate to access valve body and cartridge.
This video walks through the process nicely.

Re: Type of fixture ?
That is a Moen shower valve. They make two replacement cartridges. Purchase both and return the one that doesn't fit.
If it is as old as you say, and It looks like it is, it would be the older version of the two types that they offer.

Re: Short cycling boiler. I'm stumped.
You need to have the black wire already disconnected. this way the burner will not run at all.
As soon as you get the SideShot to operate then connect the yellow so P1 and P2 are connected
Then the burner will run
You only have 5 seconds from the start of the SideShot until the P1 and P2 are jumped for this test to work.
Re: Short cycling boiler. I'm stumped.
Does the pressure switch have an adjustment on the side of it? That may need to be changed to get this to operate properly.
Looking at the instructions, that pressure switch is not adjustable
ALSO. Jumping P1 and P2 is only a temporary test. it is not a fix. This test will prove the pressure switch is the cause of the short cycling or it will eliminate the pressure switch as the source of the short cycling.

Re: Expected operation of Gorton #2 during off cycle
You can test igmf they are venting, use an IR thermometer and a can of aerosol smoke. The smoke will show if air is flowing out the vent, and the thermometer will tell you when it should close.

You're responding to a three year old post. Plenty unvented ones on ebay though.
Re: Short cycling boiler. I'm stumped.
The red jumper on the upper right of this diagram is the prover switch.
You can use the yellow wire that is connected to the prover pressure switch on the left of the photograph. leave it connected to P2 on the PCB and remove the black wire from the P1 on the PCB. after the fan starts connect the yellow wire to P1 and that will simulate the prover switch has closed contacts and the short cycling will stop.
After the burner cycle is completed, you must remove the wire from P1 or the burner will not restart on the next cycle. Then when the next cycle starts the Side Shot again, you can jump P1 to P2 again and that will allow the burner to operate.
So P1 and P2 must NOT be connected for the Side Shot to start. P1 and P2 must be connected for the burner to start.
Re: Did I screw this up?
If you have one zone of heat, I'd run the circulator continuously. I have my circulator set this way with an outside sensor to kill the pump above 65 degrees. I'm a fan of super simple where possible.
