New to the NE and new to paying the absurd price of heating oil and I'm ready to join the anthracite club!
I am in the process of installing a df520 circa 1981. The return ports both have bushings in the original welded bungs. The port on the right (when facing the boiler) is 1 1/4 the one on the left is 1". I plan on using both as is recommended. The pump will be on the return placed on the right side and my plan is to use all 1 1/4 black pipe.
I tried to remove the 1" reducing bushing with a pipe wrench, PB Blaster, and heat to no avail. It was sealed with something pipe dope?
Question: How big of deal is it if I simply plumb it using a 1 1/4 "T" on the right hand return, use a reducing bushing to 1", nipple, union and a 1" T on the left hand return?
Question: Assuming the first answer is No big deal...What are the chances that I didn't screw up the deal when heating the bung and busing while trying to remove it? What should I pressure test it with?
Question: It the question to number 1 is they need to be the same any suggestions on how to remove the bushing that has been in there for 20+ years.
I look forward to hearing your expert answers as the sooner I get this up the sooner I can start saving money and making my wife happy for not complaining when she goes over to the thermostat.
