Inspecting the Furnace Installation
Following completion of all installation activities described in this chapter, the furnace should be
inspected by qualified personnel before firing. This ensures that your installation meets all applicable national and
local codes and allows for any deficiencies to be corrected before furnace startup.
Improper installation may void
your warranty.
Installing the Wall Thermostat
1.
Select a location for the thermostat on an interior wall away from any hot or cold drafts.
2.
Remove the top cover from the thermostat by pushing gently on the latch at the top center of the
body. (
Hold the thermostat base in one hand, and grasp the body with the other hand; push in on the
latch with your thumb, and pull the cover away from the base
.)
ATTENTION:
DO NOT use a screwdriver to pry the cover off the base, or damage may occur.
3.
Remove the green paper insert and the black plastic battery isolator from the battery section of the
thermostat.
4.
Refer to the
Burner Wiring Diagram
in
Appendix B
at the back of this manual. Run two wire,
18-gauge (minimum) thermostat cable from the terminals on the back of the thermostat base to the T/T
terminals of the primary control on the burner.
ATTENTION:
NEVER jump between T/T terminals on the primary control without removing
one of the wires. Failure to remove one of the wires will burn out the heat anticipator on the
thermostat and will cause the thermostat to fail.
5.
Mount the thermostat base 60" to 66" from the floor using the hardware provided.
6.
Reassemble the thermostat body onto the base. (
Align the hinges at the bottom of the cover with the slots
at the bottom of the base, and swing the cover up into place
.)
Replacing the Wall Thermostat Batteries
1.
Proper battery level is indicated by the room temperature being displayed on the LCD screen.
2.
When the battery level becomes low, a battery icon along with the word "REPLACE" will be displayed in
the lower left corner of the LCD screen. Replace the batteries to ensure proper operation, following the
previous instructions on the thermostat disassembly procedure.
3.
If the batteries are not replaced, the display will slowly become dim and not display any information.
The thermostat will eventually not function. If this happens, replace the batteries immediately.
1.
Refer to Figure 4Q. Follow the instructions included with the draft inducer to mount the draft
inducer on the section of single-wall vertical stack.
2.
Position the draft plate all the way out so that it does not reduce the draft produced by the draft
inducer. Follow instructions in
Section 8 (Adjusting the Draft Overfire)
to set the proper draft.
Wiring the Draft Inducer for Normal Operation*
*(No exhaust fans in the building. Read pages 8-3 to 8-6 if exhaust fans are present.)
1.
Wire the draft inducer according to the Furnace Wiring Diagram provided in
Appendix B
at the
back of this manual.
