By the way, I am a she not a he, lol, and with all the help that everyone is giving me I think I can get this done.


hopefully the box has the 3 JC relay/control boxes, aquastat well, aquastat bulb, mount rails for JC parts,draft control servo motor and mount bracket for it. you will need a 120V powe line to power up the controller setup. i have my power line with a switch in it, so it can be turned off during non heating season.
to be a bit more help full will need to know what controls water flow to zone(s) in house. zone valves? circultor pumps with back flow valves? etc. pictures of plumbing where of controls would help.theres DEFINITELY one item thats need to be wired in, A DUMP ZONE in case boiler ever over fires, gets excessively to hot. theres 2 ways to do it, either a 24v circuit using exsisting zonevalve, circulator relay, or 120V to a circullator thats dedicated to a radiant heat output thats not normally used. 24v is easiest to wire and setup, plus costs less.

looks like your missing the A350 contoller box. It will have a little knob on top half of front face with temp range markings(90*>250*) around it. And i don't see aquastat bulb for the brass well that you have. Stainless steel Bulb will have a gray covering with 2 white wires within it, coming out of one end the bulb . Gray lead wire will be about 10" long.

Do you have or have you downloaded the intallation/owners manual from Harmans website yet? This will help you a whole lot to install these parts.

If you need to you can email me at wilder11354@hotmail.com, send phone# and i can call and explain some what you need to do and a few things that you need to note, before you start drilling holles in side cover to mount controller mount rail.

ok?

Strange, why would it be missing the temp control? They look like new.

Great advice from all on here. I really thank my lucky stars you can turn to guys to help figure the coal "learning curve" out.

Once you get the auto draft and baro damper in you should be good to go.

Keep us updated.
