If Presto longer manufacturers or stocks parts for your heater, there may be a good reason for it. Other than they now have a better heater. My best advice is to scarp the heater and purchase a new one, Your model may have had a safety issue.
the baseboard heaters out put goes down a lot more than you would think when used on 120 volts ... thats because not only is the voltage half of what it should be, the current is also half .. so the total power (the product of voltage and current) is one fourth of what it would be if operated on 240 volts .. you are operating at only 186 watts instead of the 750 watts you should have .. so you would have to have 4 times as many heaters for the same heat output .. you likely have the 240 volts available (most houses do) .. there are two phases .. each 120 volts .. when both phases are used together then you get the 240 volts total .. another option is you can use heaters designed for 120 volts .. the current would increase to a little more than 6 amps per heater .. some heaters have a jumper you can move for 120 volt service or 240 volt service... you can use those with either voltage ..
if the heater is 120 volt or 240 volt its really pretty easy. at either end is a cover. remove the cover and you'll see a wirenut or maybe just two wires. one side has an integral thermostat. connect your supply to the two wires on the thermostat. connect the other end in your breaker box with the appropriate sized circuit breaker. wire size feeding it will depend on its current draw. how many watts is the heater? 1500 watts will draw 6.25 amps at 240 volts so you can use 14 ga wire. 2000 watts will draw 8.3 at 240 volts - so 14 ga is still ok. 2500 watts at 240 draws 10.41 amps. 3000 watts draws 12.5 amps at this stage I'd use 12 gauge on a 20 amp breaker.
