need help wiring a boiler and indirect water tank.

I have posted on here once before and I am very grateful for all the helpful responses. I decided to purchase a Biasi B10-4 boiler with a Heat-Flo 40 gallon indirect water heater. My plumber is set to install everything in a couple of weeks, the problem I have is the cost of my plumber and equipment has left me with not enough money to have an electrician wire everything for me. I am somewhat familiar with electrical and have installed switches, fans, lights, etc... With no problems. I am hoping that with your help I can wire the unit myself because I cannot afford an electrician at this time. The entire job is still being inspected by the City but because I have a single family home the inspectors are allowing me to do the electrical work. They would allow me to do the plumbing too but I make a lousy plumber!

My components are as follows.

Biasi B10-4 Boiler with Riello Burner
Aquastat Type L4006A
Taco SR501 Switching relay
Heat-Flo indirect fired water heater (40 Gal)
Two existing Taco Circulators 007-F5 (used for two heat zones)
One new Taco Circulator 007-F5 for Heat-Flo water heater
Intellicon HW+ fuel economizer

I know it is a lot to ask but I would greatly appreciate it if someone could type or draw up some type of schematic for me to follow. I have the schematics to all the individual components but I am confused as to how to wire everything properly for hot water priority and how to integrate the Intellicon HW+.

Rhode, You say that you have an SR501? You really need an SR504 ...

here's a rough cut of how the 504 might be wired in your system.

I'm not going to advise on the Intellicon...
