Fill the boiler and plumbing system with water prior to lighting!

Starting a fire

Fill the hopper with rice coal. With the aquastat calling for heat, the coal will begin to feed onto the grate inside the stove. This process can be accelerated by adjusting the feed rate to the maximum position. When the coal starts to come up out of the grate and is almost up to the area where the holes start, turn the feed adjuster back about 2 turns and turn off the feed motor with the switch on the side of the control box. Whether using wood pellets, charcoal, or kindling and paper, mix your starter material with the coal on the grates, for best results. Use a match to light the fire or starting material.

After the coal is burning, the feed motor can be turned on and the coal fire will continue to get larger. Fresh coal will continue to be pushed onto the grate and ashes will be pushed off the grate. The feed rate must be adjusted so the coal is burned up and turned to ashes before the coal gets to within one inch of the end of the grate. Too high of a feed rate will push unburned coal off the coal grate, therefore wasting fuel.

Feed Adjustment

The feed indicator on the side of the feeder shows how far the pusher moves each stroke. There are dots above the indicator spaced 1/8” apart. A movement of one dot would give a low burn, two dots medium and three dots high. Lock the adjuster with the wing nut after adjusting feed rate.

After the fire is burning and the feed rate is adjusted, you can now set the aquastat to the desired water tem- perature.
