United States Stove 1800GC manual Testing and Operating Procedures, Operating Notes

TESTING AND OPERATING PROCEDURES

TESTING:

1.If using an optional power draft, check the draft blower by turning the room thermostat up high enough so that the draft blower turns on. Then lower the thermostat setting until you hear it shut off.

2.Use a sheet of newspaper to test your draft by placing it inside the furnace and lighting it.

With completion of the tests above, you are ready to light the furnace. Follow the operating steps.

STARTING A WOOD FIRE

UsingMotorizedNaturalDraft

CAUTION: Never use gasoline, gasoline-type lantern fuel, kero- sene, charcoal lighter fluid, or similar liquids to start or "freshen up" a fire in the furnace. Keep all such liquids well away from the furnace while it is in use.

1.Turn up thermostat to open motorized damper.

2.Open spin draft cap on ash door.

3.Pull the slide baffle rod to the front position.

4.Open the fuel load door and light fire using kindling and several sheets of newspaper, then close the furnace door. The furnace door should remain closed for 5 to 10 minutes in order to establish the fire. If the fire has established, you are ready to load the furnace.

CAUTION: To prevent flame and smoke spillage, the slide baffle must be pulled out and the fuel door must be cracked for ten seconds before being fully opened.

Do not over fire your furnace! After you have become familiar with its operation, you should know how much wood to use.

5.Load the furnace, close the load door and push the slide baffle rod to rear.

6.Close the spin draft cap on ash door.

7.The motorized natural draft cycles on demand from the U.S. Stove wall thermostat. Setting the thermostat four degrees higher that your existing thermostat is recommended.

During operation, the motorized natural draft remains open until the thermostat temperature setting is reached.

CAUTION: To avoid excessive temperatures, do not operate with fuel door or ash pan open.

CAUTION: To avoid excessive temperatures, do not operate with fuel door or ash pan open.

STARTING A COAL FIRE

If you burn coal a Forced Air Draft is required.

!Open smoke pipe damper all the way. Open all draft controls on your 1600/1800. Pull the slide baffle forward.

!Place about 10-15 lbs. of coal in on the shaker grates. It should come up to about half of the first firebrick level.

!Place crumpled paper over the coal and criss-cross a couple handfuls of dry kindling wood 3/4" in thickness on top of paper.

!Ignite the paper and close loading door. Wait about 30

minutes until coal fire is established before adding more coal. NOTE: NEVER load coal over the level of firebrick.

!Close by-pass damper and set all draft controls to your own needs. It may take 3 to 4 coal fires to determine how your local coal and the Hotblast Furance reacts together — adjusts drafts accordingly.

!Loading with a good bed of coals in the morning — open by-pass damper.

•In normal shaking, only rock the grates a small amount to sift ash through.

•Remove all ashes every day from ash pit.

CAUTION: Ashes should be placed in a metal container with a tight fitting lid. The closed container of ashes should be placed on a non-combustible floor or on the ground well away from all combustible materials pending final disposal. If the ashes are disposed of by burial in soil or otherwise locally dispersed, they should be retained in the closed container until all coals have thoroughly cooled.

•With your poker, push hot burning embers to the rear of the unit and add green coal in front. NEVER load over height of firebrick. This can result in damage to your furnace and home.

•Close by-pass damper.

!Too much draft air will cause clinkering of coal and will waste heat up the chimney. Shut draft down to as low a point as you can and still heat your home.

1.NOTE: Never stand in front of loading door when opening it. Stand to the side.

2.NEVER completely cover the live fire with fresh coal. Always leave a generous area of burning coal at the top of the fire and at the rear.

3.Always keep the ash pit clean.

!￿If the fire goes out or does not hold overnight, look for:

1.Poor draft.

2.Incorrect damper settings.

3.Improper firing methods for coal being used.

4.More combustion air needed.

5.Coal not sized to the furnace. We recommend 1" to 3" diameter pieces of coal.

6.Ashes, if allowed to accumulate in the ash pit, will not allow the passage of required air for combustion. Keep ash pit clean.

7.This furnace is not to be used with an automatic stoker unless so certified.

OPERATING NOTES

!Do not over draft the furnace! It is designed to operate at .06 inches of water column and must be set with a draft gauge to maintain a steady draft. (Barometric Damper recommended.)

!Do not allow ashes to build up higher than 2" above grates.

!Be extremely careful when removing furnace ash pan; it can get very hot.

!With new steel, there is a small amount of oil or dirt on the metal. You may smell an odor. This is normal during the first operation. You may want to assemble the furnace out of doors and build a small fire in it to "burn off" this dirt and oil before installing the unit.
