I have installed honeywell aquastat relay per instruction manual on my dunkirk xeb-4 lp boiler furance with honeywwell ignition unit s8610u but it wont ever start the exhaust fan checked everything several...


If aquastat wirings are ok, and control module had been set up properly, the the furnace should start.
Check if bypassing the control the furnace starts, if it starts then check aquastat wirings.
If it depends on the furnace, check the valve, the safety sensor and the ignitor.
Here is the guide to set up the Aquastat control:

Disregard wire colors. Instead wire by terminal designation. In other words :
Wire on "R" Terminal on old thermostat to "R" Terminal on new thermostat no matter the color.

I had a Honeywell F4- 0019 motorised two port valve on my central heating that has failed. I have replaced it with a Honeywell valve from Thompsons Plumbase, but on fitting noticed the new valve has six...


I'm doing a lot of guessing here for lack of information. You have a residential boiler and hydronic heating system that is zoned around your home and each zone has an independent thermostat?
Again, I need to guess. The old valve was spring return with yellow, blue and red wires? If all is true so far, then I think you had a single end switch with one COMMON - one NORMALLY OPEN and one NORMALLY CLOSED contact. 6 wires would make up 2 end switches. Brown is a normal color for one lead of an end switch. If this is all true, your new switches are probably NORMALLY OPEN and you only need 1. If this did not help you, give me a better description of old and new and I will get this correctly answered for you.

Baxi solo WM 50/4 RS pilot light is lit, Boiler will heat water but not rads have you any ideas thanks sam


Double check that the programmer is calling for the boiler to fire, and also that the thermostat is turned up enough.... you will hear it click as you turn it up... if the radiators still dont get warm...
then In the airing cupboard there should be a pump on a three port valve that says A,B, and AB on the different pipe outlets... It seems that this is possibly stuck in one position.... Sometimes the servo motor on top of the three port valve (square metal box with wires going into it) goes weak and requires replacement, these are not expensive from a decent plumbing spares shop I.e Pts (plumbing trade supplies) and are a doddle to install, just isolate power to it, take square the top cover off the valve to reveal the innards and you will see it straight away... Like a round brass cylinder with a flat top... It should have two screws holding it in...

Hope this helps
Thanks

Hi; I first want to know if You can use a millivolt generator operated pilot valve sized to fit Your gas supply line. Secondly does Your existing main gas valve supply the pilot gas. This is very important and I need to know before I can give You options...Lastly I have to tell You never tell a public help engine that You have removed any safety feature from a gas appliance.

Domestic oil fired central heating. Keeps tripping out with no oil feed(has tiger loop and this is empty) If oil is drawn through filling tiger loop again boiler will fire up and run for betweeen 2 days...


many times the feeder tube from the bottom of the tank becomes perforated. the return tube is ok most of the time . try switching the 3 8 tubes from inlet to outlet and see if problem resolved. if so the the tube down into the tank is flawed.
