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 for 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.
• This furnace must be installed ONLY in the prescribed
manner shown in illustrations 1, 2, or 3 under the In-
stallation Examples in this manual. It is NEVER to be
installed as a counter-
fl
ow or down-draft furnace, or
in any manner wherein the heated air is directed in a
downward
fl
ow into the home or toward to an existing
central furnace.
• NEVER INSTALL outside the home.
• 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 speci
fi
cations 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 insu-
lation, 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
fi
ed
in these instructions. Doing so may void your warranty.
LOCATING YOUR FURNACE
The furnace is to be installed maintaining the clearances
speci
fi
ed in the following illustrations.
Do not place the furnace directly on a combustible
fl
oor.
If you are placing it on a combustible
fl
oor, an approved
fi
re retardant material, equivalent to 3/8” UL Listed mill-
board, should be placed under the unit. The material must
extend at least 16 inches beyond the front of the unit and
8 inches on either side of the fuel loading door opening. It
must also extend underneath the chimney connector and
to each side of the connector by at least 2 inches.
CLEARANCES
REDUCED CLEARANCES
NFPA guidelines and most codes permit reduced clear-
ances to combustible walls and ceilings if adequate pro-
tection 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 actually
provides 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
fi
re hazard.
A wall can be kept cool using these items but only if they
are mounted and spaced out from the wall by an inch or
two to allow free air circulation behind the protective panel.
The protective panel should also have a gap between the
fl
oor and ceiling.
Three rules to follow when constructing wall protectors:
1. Non-combustibility of all materials including mount-
ing and supporting.
2. A well ventilated air space between protector and wall.
3. Suf
fi
cient strength and rigidity so that the protector
and air space will be durable.
