Having trouble removing the coupler from my EFM worm....I do know that the threads are left handed.....Does the coupler thread from both ends or is it permanently fastened on one end....Would heat help? looking for any ideas
Thanks in advanced,
Stoker Coal Boilers automatically feed the coal and have controls and pumps just like any conventions boiler. They are intended to be used as a primary heat and often have domestic hot water coils as an added bonus. They can be set up independently or in dual sytem with your existing oil/gas boiler. They can accommodate both hot water base board or steam plumbing.

The coupler is threaded on both ends. Spray it with some penetrating fluid, and carefully give it a try with a pipe wrench.
