INSTALLATION FOR WW COMPUTERIZED PROGRAMMERS
WTNFII-10 & WTNFII-19
1) Be sure that your programmer is the same voltage as your burnout furnace:
WTNFII-10 - 240V
WTNFII-19 - 120V
Note - Do not plug in furnace or programmer at this time.
2) Mount programmer next to furnace. Holes are provided in the rear of the cabinet for hanging
your programmer on the wall with screws. A wall outlet of the proper voltage and amperage with a
dedicated line should be within 5 ft. (Do not use an extension cord). NOTE: THE WTNFII-19
COMPUTERIZED PROGRAMMER COMES WITH A NEMA 5-20R PLUG ON THE POWER CORD. IF
YOUR FURNACE IS RATED AT MORE THAN 20 AMPS, YOU CANNOT USE THIS PROGRAMMER. IF
YOUR FURNACE DRAWS LESS THAN 20 AMPS, YOU MAY INSTALL A STANDARD PLUG AT THE
AMPERAGE OF YOUR FURNACE. A LICENSED ELECTRICIAN SHOULD BE USED FOR ALL
ELECTRICAL WORK.
3) Insert the thermocouple into the hole at the back of the furnace. If no hole has been provided,
one must be drilled. CAUTION: DO NOT DRILL INTO HEATING ELEMENT. BE SURE THAT NO
METAL IS IN CONTACT WITH THERMOCOUPLE METAL PARTS.
4) Insert furnace line cord into socket on side of programmer. (NOTE: 120V and 240V PLUGS
COME IN MANY STYLES - IF YOUR PLUG DOES NOT MATCH THE SOCKET, IT MUST BE
REPLACED WITH ONE THAT DOES FIT) Your Computerized Programmer is rated for a maximum
of 20 Amps.
5) Insert programmer line cord into wall outlet. Again, if plug does not match outlet, outlet must be
replaced or unit can be wired direct. If wired direct, it must be done by a licensed and qualified
electrician. NOTE: WHEN POWER IS FIRST APPLIED, THE PROGRAMMER ALARM WILL GO OFF
FOR APPROXIMATELY TWO SECONDS..
6) The display will alternately read [ ldLE ] and the current temperature in the furnace.
7) If the display does not read [ ldLE ], press “STOP” then press “ENTER”.
8) Turn the furnace control to HIGH and your installation is complete. Now you can start using the
programmer.
9) To activate a program, refer to the operating instructions of our burnout furnaces.
NOTE: EVEN THOUGH THE PROGRAMMER IS OFF AT THIS TIME, THE UNIT WILL DISPLAY
THE AMBIENT TEMPERATURE INSIDE THE FURNACE.
