    condensate heating for a one pipe steam boiler

    Hello, I'm am an industrial plumber, working for a big company in the Northeast, however this question is for my own personal system. Could you please tell me how to wire in the aquastat (L4006A) model with the gas valve (Robertshaw-Grayson) coming from a relay (RA832A). I have power to the relay with the thermostat doing the controlling of my Taco circulator. I would like to be able to fire the boiler for the condesate loop, with out making steam, but I'm not sure of the wiring, trying not to burn out the gas valve and or relay. Please help. Sincere thanks.
