CAUTION
This heater is designed to operate at 120 or 240 VAC. It is not recommended to be connected to OR operate on a 208 VAC.
NOTE
•The MiniMax NT heater is prewired for 240 volt AC connection using the “RED/BROWN” female connector and the “WHITE” common male connector; see below, Figure 16. If you require the heater to be connected to 120 volts AC, remove the “RED/BROWN” female connector from the “WHITE” common connector; now locate the “BLUE” female connector and plug it into the “WHITE” common connector.
•When connecting the home wiring to the “Line Terminal Block” inside the junction box, follow the polarity as shown below. Connecting to 120 VAC, make sure that you connect the positive wire to the positive terminal (L), the neutral wire is connected to the neutral terminal (N) and the ground is connected to the ground terminal (GND); see below, Figure 17.
•If any of the original wiring supplied with this heater must be replaced, installer must supply (No. 18 AWG, 600V, 105° C. U.L. approved AWM low energy stranded) copper wire or it’s equivalent. Thermal fuse wiring must be replaced with 18 AWG, 600V, 150° C. temp. rating.
CAUTION
The installation must conform with local codes or, in the absence of local codes, with the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or CSA B149.1, Natural Gas and Propane Installation Codes. If an external electrical source is utilized, the heater, when installed, must be electrically grounded and bonded in accordance with local codes or, in the absence of local codes, in the USA, with the National Electrical Code, ANSI/NFPA 7; in Canada, with Canadian Electric Code, CSA C22.1.
Always use crimp type connectors when connecting two wires.
