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

 

NOTE: For further information on using your furnace safely, 

obtain a copy of the National Fire Protection Association 

publication “Using Coal and Wood Stoves Safely.” NFPA 

NO.  NW-8-1974.  The  address  of  the  NFPA  is  470  Atlantic 

Ave., Boston, Massachusetts 02210.

 

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

THIS IS A WOOD AND COAL BURN-

ING FURNACE AND SHOULD NOT BE 

ALTERED  IN  ANY  WAY!    DOING  SO 

WILL VOID YOUR WARRANTY!

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.
