INTRODUCTION

Thank You for your purchase of a U.S. Stove Coal Burning External Furnace. Your decision to buy our Clayton 

Furnace was undoubtedly reached after much careful 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 furnace not only with the purchase, but for recommendations 

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. 

IMPORTANT

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 dependable 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 suitable 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 anyone who is unfamiliar with the furnace to operate it.

•  Spend adequate time with your furnace to become 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.

DISCLAIMER NOTICE

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

GENERAL INFORMATION

Your 1600EF furnace comes ready for installation. No assembly required. Unpack your furnace and insure that 

there is no shipping damage. If damage exist, please contact your dealer immediately. Review the items included 

with your furnace located inside the firebox.

This furnace may be installed as a Stand-Alone Central Furnace or as a Supplementary Furnace in the US only. 

For Canadian installations, it may be installed as a Stand-Alone Central Furnace Only.

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 existing 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 noncombustible base, preferably a 4’ x 8’ concrete pad, as 

close to the home as clearances to combustibles will allow. 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 recommended 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 temperatures 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 

combustibles is 20”.
