INTRODUCTION

Thank You for your purchase of a U.S. Stove Wood/Coal 

Burning External Furnace. Your decision to buy our Clay-

ton Furnace was undoubtedly reached after much care-

ful  thought  and  consideration.  We  are  very  proud  you 

chose this furnace and trust you will receive the comfort 

and economy that others realize when heating with a U.S. 

Stove product.
Your dealer is important in your experience with the fur-

nace  not  only  with  the  purchase,  but  for  recommen-

dations  for  professional  installation  for  your  home.  The 

qualified  professional  installer  has  been  expertly  trained 

in  solid-fuel  furnace  installation  to  assure  the  safety  and 

comfort for your family while saving you money. Trust your 

experienced installer. They are specialist in this field. 

Before installing and using your furnace, please read the 

following pages thoroughly and carefully. If you follow the 

instructions, your furnace will give you safe and more de-

pendable service for years to come.

• Check  your  local  codes.  This  installation  must 

comply with their rulings.

• This is an outdoor hot air furnace and must NOT 

be installed inside the home or a building.

• This  furnace  must  be  connected  to  a  110  volt 

Ground Fault Circuit Interrupter (GFCI) outlet suit-

able for outdoor use.

• A  back-up  generator,  2,000  watts  minimum,  is 

recommended in case of a power failure.

• Always  have  a  properly  functioning  smoke  or 

ionization detector and a CO detector installed 

in your home.

• To prevent injury or damage, do not allow any-

one who is unfamiliar with the furnace to operate 

it.

• Spend adequate time with your furnace to be-

come well acquainted with the different settings 

and how each will affect its burning patterns. It 

is  impossible  to  state  just  how  each  setting  will 

affect your furnace because of the variations in 

each installation.

The BTU ranges and heating capacity specifications are 

provided as a guide and in no way guarantee the output 

or  capacity  of  this  unit.  The  actual  BTU  output  depends 

on the type of fuel being burned and its conditions, the 

thermostat setting, the draft adjustment and the chimney 

to  which  the  unit  is  attached.  The  actual  area  that  this 

unit will heat depends on factors such as the conditions 

of the building, heat loss, type of construction, amount of 

insulation, type of air movement, the location of the unit 

and more importantly the duct work and return air facility.

Warning:

Do not alter this appliance in any way other than speci-

fied in these instructions. Doing so may void your warranty.

Your 1600EF furnace comes ready for installation. No as-

sembly  required.  Unpack  your  furnace  and  insure  that 

there  is  no  shipping  damage.  If  damage  exist,  please 

contact  your  dealer  immediately.  Review  the  items  in-

cluded with your furnace located inside the firebox.

This  furnace  may  be  installed  as  a  Stand-Alone  Central 

Furnace or as a Supplementary Furnace. If installed as a 

Central Furnace, this unit will have it’s own central ducting 

system  and  will  essentially  be  your  primary  heat  source. 

If  installed  as  a  Supplementary  Furnace,  the  1600EF  will 

assist an Electric, Gas or Oil Fired Furnace in heating your 

home by utilizing the existing furnace’s duct work system. 

The 1600EF 

must not be

 wired in conjunction with the exist-

ing furnace. The outdoor furnace may be operated with 

the supplied wall thermostat or a 24 volt thermostat that 

you supply yourself.
The furnace should be placed outdoors on a level non-

combustible base, preferably a 4’ x 8’ concrete pad, as 

close to the home as clearances to combustibles will al-

low. If locating the furnace more than 10 feet away from 

the home, a minimum of 6 feet of Class “A” HT 2100 All 

Fuel  6  inch  chimney  pipe  is  required  - 

Do not place the 

furnace more than 40 feet away from the home. 

Maintain 

all clearances stated in this manual.
Class “A” HT 2100 All Fuel 6” Chimney Pipe is recommend-

ed  for  optimum  performance  and  can  be  purchased 

from  your  local  dealer.  A  Chimney  Base  Plate  should 

be  installed  over  the  flue  outlet  and  sealed  to  maintain 

weather resistance. A 2” clearance to combustibles must 

be  maintained  from  the  pipe.  We  suggest  using  either 

Simpson  Dura-Vent  or  Metal  Fab  chimney  products  for 

your installation.
If you choose to use single wall stainless, the flue temper-

atures will be reduced which promotes the formation of 

creosote, possibly creating a fire hazard. If you use single 

wall  stainless  pipe,  the  minimum  clearance  to  combus-

tibles is 20”.
Attach the appropriate chimney pipe lengths to the cho-

sen chimney base plate and finish with a rain cap. Secure 

the chimney with guy wires to each of the four anchors 

point on the furnace. Your furnace requires it’s own chim-

ney system and can not share a flue with another appli-

ance.
Once you have selected a location for the furnace and 

connected your furnace to a chimney and a 110 volt GFCI 

outlet, you will need to commence an initial firing. 

DO NOT 

connect the furnace to your duct work at this time.

 Your 

new furnace has a protective coating of oil and paint on 

the surface which could produce smoke or odors during 

the initial firing and will burn off. 

Build a small fire - DO NOT 

fill the firebox to it’s full capacity for the initial burn.

  This 

initial firing allows the metals and castings to cure.
After completing the firing and allowing it to cool, you are 

ready to finish the installation. Refer to the remainder of 

this manual for detailed instructions.
