AWARNING
E
Improper
installation
may
damage
equipment,
can
create
a
shock
hazard,
and
will
void
the
warranty.
The
furnace
shall
be
installed
so
the
electrical
components
are
pro-
tected
from
water.
The
furnace
is
not
to
be
used
for
temporary
heating
of
buildings
or
structures
under
construction.
Do
not
test
the
fuel
system
at
more
than
14
inches
water
column
after
furnace
has
been
connected
to
the
fuel
line.
Such
testing
may
void
the
warranty.
Any
test
run
above
14
inches
water
column
may
damage
the
furnace
control
valve
which
could
cause
an
explosion,
fire,
or
asphyxiation.
The
following
requirements
to
be
met:
a.
Clean, outside
combustion
air
is
provided
to
the
furnace
to
minimize
the
impact
of
corrosive
adhesives,
sealants,
and
other
construction
materials.
Drywail
dust
is
a
major
concern
during
construction,
which
can
be
pulled
into
the
combustion
air
path,
leading
to
plugged
heat
exchangers,
burners, and
inducer
assemblies.
b.
Filter
must
be
installed
in
the
furnace
as
specified
in
the
installation
instructions,
and
musi
be
replaced
or
thoroughly
cleaned
prior
to
occupancy
of
the
home.
Again,
drywall
dust
is
the
key
issue,
as
that
dust
can
be
pulled
into
the
circulating
blower
motor,
plugging
the
motor
vents,
coating
the
rotors
and
stators,
etc.
which
can
lead
to
a
potential
fire
hazard.
c.
The
temperature
of
the
return
air
to
the
furnace
must
not be
less
than
55°
F
(13°
C),
with
no
evening setback
or
furnace
shutdown,
to
prevent
condensation
in
the
primary
heat
exchangers.
d.
The
air
temperature
rise
must
be
within
the
stated
rise
range
as
indicated
on the
furnace
rating
plate,
and
the
firing
input
rate
must
be
set
to
the
unit

value.
