IMPORTANT
Before installing and using your Clayton Furnace, please read
the following pages thoroughly and carefully. If you follow the
instructions, your Clayton furnace will give you safe and more
dependable service in the years to come.
First step; check your local codes. This installation must
comply with their rulings.
Do not install this furnace in a mobile home or trailer.
Always have a 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 some time with your furnace to become well
acquainted with 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 pro-
vided as a guide only and in no way guarantee the output or
capacity of the units. 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 the 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, and the location of the
unit, and more importantly, your duct work and return air facility.
WARNING:
Do not alter this appliance in any way. Doing so may void
your warranty.
LOCATING YOUR FURNACE
The furnace is to be installed maintaining clearances as shown
in illustration.
Do not place the furnace directly on a combustible floor. If you're
placing it on a combustible floor, an approved fire retardant
material equivalent to 3/8" UL Listed millboard should be placed
under the furnace. The material must extend at least 16" in front
of and 8" on either side of the fuel-loading and ash-removal doors,
and underneath the chimney connector and extending at least 2"
on either side of the chimney connector.

CLEARANCES
REDUCED CLEARANCES
NFPA guidelines and most codes permit reduced clearances to
combustible walls and ceilings if adequate protection is added.
A common mistake is to assume that sheet metal, masonry, or
millboard placed directly against a wall protects it. Materials
installed in this manner give very little protection. These materials
are good heat conductors, so they will be almost as hot on their
back side as they are on the exposed side. Therefore, the
combustible wall behind is still a fire hazard.
A wall can be kept cool using these items but only if they're
mounted and spaced out from the wall by an inch or two to allow
free circulation of room air behind the protective panel. The
protective panel should start within a few inches of floor level.
The three rules to follow when constructing wall protectors:
1. Non-combustibility of all materials including mounting
or supporting.
2. A well ventilated air space between protector or wall.
3. Sufficient strength and rigidity so that the protector and
air space will be durable.
CHIMNEY REQUIREMENTS
A fireclay lined masonry or Class A 103HT All-Fuel Metal Insu-
lated Chimney must be used in all airtight wood furnace instal-
lations. The minimum recommended flue size for the U.S. Stove
Clayton Furnace is 6" (inside diameter) for round flues, and 7" x
7" for square flues. When making new chimney installations,
always follow the chimney manufacturers instructions.
