United States Stove 1600EF installation instructions Operating Notes

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.

There are ONLY two types of coal allowed for use in this furnace: Bituminous Coal (soft coal) and Anthracite Coal (hard coal). NEVER USE Cannel (or Channel) coal or Brown (Lignite) Coal.

See our Bulletin RC454 at the rear of this manual for the best information available on burning coal.

OPERATING NOTES

DANGER: Risk of Fire or Explosion - Do not burn garbage, plastics, gasoline, drain oil or other flammable liquids. Plastics, when burned, form hydrofluoric and hydrochloric acids which will damage and destroy your furnace pipe and chimney. The burning of trash or oil can result in an extremely hot fire and is sometimes a cause of chimney fires. NEVER BURN GREEN WOOD OR TIRES.

WARNING: Risk of Fire - Do not operate with flue draft exceeding .06 inches of water column and must be set with a draft gauge to maintain a steady draft. (Barometric Damper recommended.)

Do not operate with the fuel loading or ash removal doors open.

Do not store fuel or other combustible material within marked installation clearances.

Inspect and clean your flues and chimney regularly.

CAUTION: Hot Surfaces - Keep children away. Do not touch during operation. Maximum draft marked on nameplate.

Equip your home with fire extinguishers and smoke de- tectors appropriately located.

Wood should be placed directly onto the cast iron shaker grate of the Clayton furnace. Do not use additional grates and/or irons.

Do not allow ashes to build up higher than 2” above grates.

Never allow the ashes in the ash pan to touch the grate section. REMOVE ASHES FREQUENTLY!

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 build a small fire in the furnace to “burn off” this dirt and oil before installing the duct work.

The furnace is designed to burn air dried wood and coal at a predetermined firing rate. Over firing could result in damage to the heat exchanger and cause danger- ous operation. Over firing occurs when the ash door is left open during operation or a highly volatile fuel, i.e. large amounts of small kindling, is used. If any portion of the connector pipe glows orange or red, you are in an over-firing situation. Close all dampers.

When tending the firebox always pull the baffle slide rod out prior to opening load door. Open load door slowly to avoid a “flash back”. After closing load door, push the baffle slide rod to the rear.

In event of chimney fire, shut all draft controls and call your fire department immediately. Alert everyone in the house. If the fire is still burning vigorously, throw baking soda into firebox or discharge a fire extinguisher into the firebox. After chimney fire is over, completely inspect system for damage before further use.

NEVER throw water on the fire or at the furnace, as rapidly expanding steam could result in a severe scalding.

Slow fires: It is not recommended burning the Clayton furnace any more than necessary early in the fall and late spring, as you cannot keep the firebox hot enough (without overheating your home) to burn gases. Slow fires can cause excessive creosote build-up in smoke pipe, chimney and firebox.

Inspect air filters regularly. The air filter should be changed at least every 30 days.

Oil motors every 90 days with a few drops of 30 wt. oil.

Check the fit on the load door. It must fit tightly. If it does not, check for deterioration or wear of the ceramic rope seal. Replace defective seals.

In the event of a power failure, the furnace will not dis- tribute heat to the home. We recommend the use of a back-up generator, 2,000 watts minimum, for continued use until regular power is restored

THIS IS A WOOD AND COAL BURN- ING FURNACE AND SHOULD NOT BE ALTERED IN ANY WAY! DOING SO WILL VOID YOUR WARRANTY!

CREOSOTE - FORMATION AND NEED

FOR REMOVAL

When wood is burned slowly, it produces tar and other organic vapors, which combine with expelled moisture to form creosote. The creosote vapors condense in the rela- tively cool chimney flue of a slow-burning fire. As a result, creosote residue accumulates on the flue lining. When ignited, this creosote makes an extremely hot fire.

The chimney should be inspected at least twice monthly during the heating season to determine if a creosote build- up has occurred. If creosote has accumulated, it should be removed to reduce the risk of a chimney fire.
