Install this furnace
only in a location
and position
as specified
in
LOCATION
and INSTALLATION
sections
of these instructions.
Combustion
products
must be discharged
outdoors.
Connect
this
furnace
to an approved
vent
system
only,
as specified
in the
Combustion
Air and Vent piping
sections
of these instructions.
Never test for gas leaks with an open
flame. Use a commercially
available
soap solution
made specifically
for detection
of leaks to
check all connections
as specified
in the GAS PIPING
section of
these instructions.
Always
install
the
furnace
to
operate
within
the
furnace's
intended
rise range
with
a duct system
which
has an external
static pressure
within
the allowable
range
as specified
in the SET
TEMPERATURE
RISE section of these instructions.
When
a furnace
is installed
so that
supply
ducts
carry
air
circulated
by the furnace
to areas outside
the space containing
the
furnace,
the return air shall also be handled
by ducts sealed
to the
furnace
casing
and terminating
outside
the space
containing
the
furnace.
A gas-fired
furnace
for installation
in a residential
garage must be
installed
as specified
in the Hazardous
Locations
section
of these
instructions
and Fig. 5.
The furnace
may be used for construction
heat provided
that the
furnace
installation
and
operation
complies
with
the
first
CAUTION
in the LOCATION
section
of these instructions.
This gas furnace
may be used for construction
heat provided
that:
•
The furnace is permanently
installed with all electrical
wiring,
piping,
air filters, venting
and ducting
installed
according
to these installation
instructions.
A return air
duct is provided,
sealed to the furnace
casing,
and ter-
minated
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
products
into the structure.
•
The furnace is controlled
by a thermostat.
It may not be
"hot wired" to provide
heat continuously
to the struc-
ture 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 en-
trainment 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 instruc-
tions.
•
The air temperature
rise is within
the rated rise range on
the furnace
rating plate, and the firing rate has been set
to the nameplate
value.
•
The filters used to clean the circulating
air during
the
construction
process must be either changed
or thor-
oughly
cleaned
prior to occupancy.
•
The furnace, ductwork
and filters are cleaned
as neces-
sary to remove
drywall
dust and construction
debris
from all HVAC system
components
after construction
is completed.
•
After construction
is complete,
verify furnace
operating
conditions
including
ignition,
input rate, temperature
rise and venting,
according
to the manufacturer's
in-
structions.
If this furnace
is installed
with a direct-vent
(combustion
air and
flue) system,
a factory
accessory
termination
kit must be installed.
In a direct-vent
system,
all air for combustion
is taken
directly
from the outside
atmosphere
and all flue products
are discharged
to the
outside
atmosphere.
See furnace
and factory
accessory
termination
kit instructions
for proper
installation.
These furnaces
are shipped
with the following
materials
to assist
in proper
furnace
installation.
These materials
are shipped
in the
main blower
compartment.
