Harman Magnum Stoker Restoration...

A Coal stoker furnace or stove controls most operations including automatically feeding the coal. They are quite similar to any conventional oil and gas units and easily operated for extended periods of time. They commonly use rice coal but may use larger sizes like buckwheat. They can be used as primary heat, supplementary heat or have a dual set up with your existing oil/gas furnace.

I've completed the restoration and am now moving onto the installation phase of this project. It's cheaper for me to run the heat pump until the temps are consistently below mid 40s so I don't turn on the boiler or stove until late October. I've got a quite a bit to do still (fire up the stove to burn the paint off, move/set the stove in place, install the stove pipe + ductwork) and am hoping to finish up in the next 3 weeks.

All hardware have been replaced with grade 8 and there's permatex anti-seize/rust preventive on all the threads.

Pretty!

New glass...

Old grates... ground them down on the sides to fit better (have a new set as well but these looked good enough to use for another season).

First firing will be tonight outside to burn off the paint with a make-shift flue/chimney. My coal mice ingredients. Wood pellets, rice coal, paper from a shredder, lump charcoal. Mix up in a paper lunch bag.

Job well done! :clap: :up:
Tip: for starting the stove, all you need are the wood pellets and a little jelled alcohol, in the middle of a pile of rice on the grates. Rice starts easy. :idea:

The homemade coal rice worked great... lit the first time.

I did stuff the lunch bag full and some of the contents fell into the ash pan once the bag burned but there was definitely enough "stuff" to light the stoker with ease. I don't think I even need a bag for next time. just pile the contents on the grates... light and let her rip. Chris (DVC500 at last) is spot on... with a handful of wood pellets lighting a stoker is E-A-S-Y!

Here are a couple of videos of the first burn...
