Canadian LP/Propane
Gas Sea Level and High
Altitude Conversion
Kit- P/N 904091A
This kit is for LP/propane conversions in Canada
at altitudes between zero and 4500 ft. above sea
level. Follow the installation instructions supplied
with the kit for proper installation.
CAUTION:
To avoid
electric
shock,
personal
injury, or death, turn off the power at
the disconnect
or the main service
panel
before
making
any
electrical
connections.
ELECTRICAL
WiRiNG
Electrical
connections
must be made in ac-
cordance
with all applicable
local codes and
ordinances,
and with the current revision of the
National Electric Code (ANSI/NFPA 70).
For Canadian installations electrical connections
and grounding
must be done in accordance
with the current Canadian Electrical Code (CSA
C22.1 Part 1) and/or local codes.
If any of the
original wire as supplied with the furnace must be
replaced, it must be replaced with wire having a
minimum
temperature
rating of 105°C. Refer to
the furnace nameplate and Table 12 for electrical
requirements.
Line Voltage Wiring
The line voltage (115 volt) to the furnace must
be supplied
from a dedicated
branch
circuit
containing the correct fuse or circuit breaker for
the furnace. See Table 12. An electrical switch
should be readily accessible
from and within
sight of the furnace.
(See the Wiring Diagram
label in the furnace and Figure 26.)
The furnace cabinet must have an uninterrupted,
unbroken ground to minimize
injury should an
electrical fault condition occur.The controls used
in this furnace require an earth ground to operate
properly. Acceptable
methods for grounding are
electrical wire or conduit approved for electrical
ground service. Do not use gas piping as an
electrical ground.
NOTE:
Proper line voltage
polarity must be
maintained
in order for the control system
to operate correctly. Verify that the incoming
neutral line is connected to the white wire and
the incoming "hot"
line is connected
to the
blackwire
in the junction box.These
furnaces
will not operate unless polarity and ground
are properly connected.
See Figure 23.
Label all wires prior to disconnection
when servicing
controls.Wiring
errors
can cause
improper
and dangerous
operation.
Verify
proper operation
after servicing.
Low Voltage Wiring
Install the thermostat
per the manufacturer's
instructions.The
low voltage (24 volt) connections
from the thermostat are made at the terminal strip
on the control board in the furnace. See Figure
24 for the proper connections
for heating only
(two-wire) and heating/cooling
(four-wire) appli-
cations.The recommended
minimum wire gauge
for thermostat
wiring is shown in Table 12.
The thermostat
must not be installed on an
outside wall or any other location where its opera-
tion may be adversely affected. Adverse affects
include radiant loading from fireplaces, sunlight,
or lighting fixtures, and convective loading from
warm air registers or electrical appliances.
