Frozen Water Pipe Hazard
.your
furnace
remains
off for an extended
time, the pipes in your
home
could freeze
and burst, resulting
in serious
water
damage.
WATER DAMAGE TO PROPERTY HAZARD
Failure to protect against the risk of freezing could
result in property damage.
Do not
leave
your
home
unattended
for
long
periods during freezing weather without
turning off
water supply and draining water pipes or otherwise
protecting
against
the risk of frozen
pipes
and
resultant
damage.
Your furnace
is designed
solely to provide
a safe and comfortable
living environment.
The furnace
is NOT designed
to ensure
that
water
pipes will not freeze.
It is equipped
with several
safety
de-
vices that are designed
to turn the furnace
off and prevent
it from
restarting
in the event of various
potentially
unsafe
conditions.
If the structure
will be unattended
during
cold weather
you should
take these
precautions.
Turn off the water supply to the structure
and drain the water
lines if possible
and add an antifreeze
for potable
water to
drain
traps
and toilet tanks.
Open
faucets
in appropriate
areas.
-or-
Have
someone
check
the structure
frequently
during
cold
weather
to make
sure
it is warm
enough
to prevent
pipes
from freezing.
Instruct
them
on a service
agency
to call to
provide
service,
if required.

Install a reliable
remote sensing
device that will notify some-
body of freezing
conditions
within
the home.

CARBON MONOXIDE POISONING HAZARD.
Failure
to
properly
vent
this
furnace
or
other
appliances
could result in death or personal
injury.
If this furnace
is replacing
a previously
common-
vented furnace,
it may be necessary
to resize the
existing
vent system
to prevent
oversizing
prob-
lems for the other
remaining
appliances(s).
See
Venting and Combustion
Air Check in the 4. Gas
Vent Installation
section
of this instruction.
Location and Clearances
If furnace
is a replacement,
it is usually
best to install the furnace
where the old one was. Choose
the location
or evaluate
the exist-
ing location
based
upon the minimum
clearance
and furnace
di-
mensions
(Figure
1).
CARBON MONOXIDE POISONING HAZARD.
Failure
to follow
safety
warnings
exactly
could
result in death or personal
injury.
Do
NOT
operate
furnace
in
a
corrosive
atmosphere
containing
chlorine,
fluorine
or any
other
damaging
chemicals,
which
could
shorten
furnace
life.
Refer
to 3. Combustion
& Ventilation

Installation Requirements
Install
furnace
level.
This furnace is NOT to be used for temporary heat of buildings
or structures under construction.
Install furnace
as centralized
as practical
with respect
to the
heat distribution
system.
Install the vent pipes as short as practical.
(See 4. Gas Vent
Installation
section).
Do NOT install furnace directly on carpeting, tile or other com-
bustible material. See 9, Ductwork and Filter Sub-base
for
Combustible
Floors.
6.
Maintain
clearance
for fire safety and servicing.
A front clear-
ance of 24" is minimum
for access
to the burner,
controls
and
filter. See clearance
requirements
in Figure
1.
7.
Use a raised
base
if the floor is damp
or wet at times.
8.
Residential
garage
installations
require:
•
Burners
and ignition
sources
installed
at least 18" (457
mm) above
the floor.
•
Furnace
must be located
or physically
protected
from
possible
damage
by a vehicle.
9.
If the furnace
is to be suspended
from the floorjoists
in a base-
ment or a crawl space or the rafters in an attic, it is necessary
to
use steel pipe straps
or an angle
iron frame
to attach
the fur-
nace. These
straps
should
be attached
to the furnace
bottom
side with sheet
metal screws
and to the rafters
or joists
with
bolts.
The
preferred
method
is to use an angle
iron frame
bolted
to the rafters or joists.
10. This furnace
may be used for construction
heat provided
that:
•
The furnace
is permanently
installed
with all electrical
wir-
ing,
piping,
venting
and
ducting
installed
according
to
these installation
instructions.
A return air duct is provided,
sealed
to the furnace
casing,
and terminated
outside
the
space
containing
the furnace.
This
prevents
a negative
pressure
condition
as created
by the circulating
air blower,
causing
a flame
rollout
and/or
drawing
combustion
prod-
ucts into the structure.
The furnace
is controlled
by a thermostat.
It may not be
"hot wired"
to provide
heat
continuously
to the structure
without
thermostatic
control.
•
Clean
outside
air is provided
for combustion.
This is to
minimize
the corrosive
effects
of adhesives,
sealers
and
other construction
materials.
It also prevents
the entrain-
ment of drywall
dust into combustion
air, which can cause
fouling
and plugging
of furnace
components.
•
The temperature
of the return
air to the furnace
is main-
tained
between
55 ° F (13 ° C) and 80 ° F (27 ° C), with no
evening
setback
or shutdown.
The
use of the furnace
while the structure
is under construction
is deemed
to be
intermittent
operation
per our installation
instructions.
•
The air temperature
rise is within the rated rise range on
the furnace
rating
plate, and the firing rate has been set to
the rating
plate value.
