Mark, have you turned the Control Knob from the Pilot position to the ON position?
If you have and it didn't light the burner, how tight did you install the Thermocouple connection to the Gas Control Valve? If you tightened fully with a wrench, you over tightened it. Loosen the nut and take the fitting out, wait 2 minutes. Then, reinsert it, tighten it only finger tight and with the appropriately sized open end wrench tighten it ONLY 1/4 turn more. No more and no less.
You didn't mention is you have a Millivolt Burner (Remote Ready) or a Thermostat Controlled Burner.
If it's a Millivolt Burner make sure that the leads from the Thermopile are attached to the TH & TP connectors of the Gas Control Valve. If you have a Remote Control, the leads should be on the TH & TPH terminals.
If it's a built-in hydraulic thermostat burner, the leads go on the TP & TH terminals
