Need manual for Hi Seas Heater too!
Anyone have luck finding a manual for Hi Seas Diesel Heater? I have an old one on my boat that worked fine but now it just burns on high. Seems to be something in the control valve shot. I know it was built by the Marine Heat Corp in Seattle but they are gone now. Any ideas? I wondered if any other brand control valve could be fitted??
Too bad..the thing was awesome when it functioned right!
