Electrical Connections 

 
The T-K1S requires a 60 Hz 120 VAC electrical 
power supply, and it should be properly grounded 
in accordance with the most recent edition of the 
National Electrical Code, ANSI/NFPA 70 and any 
local codes. In Canada, all electrical wiring to the 
heater should be installed in accordance with the 
Canadian Electrical Code, CSA C22.1 Part 1, and 
any local codes. Do not rely on the gas or water 
piping to ground the metal parts of the heater. 
 

: Label all wires prior to disconnection 

when servicing controls. Wiring error can cause 
improper and dangerous operation.  Verify proper 
operation after servicing. 
•  A means for switching off the 120 VAC power 

supply must be provided. 

•  Wire the heater exactly as shown in the wiring 

diagram. 

•  A green screw is provided in the junction box 

for the grounding connection.
