Superior DT-400CMN, DR-400CMP, DR-400CEN Field Wiring, A. SIT and Honeywell Millivolt Wiring

Step 4. FIELD WIRING

The gas valve is set in place and pre-wired at the factory on both models.

A. SIT and Honeywell Millivolt Wiring

(See Figure 44 ) –

1. Select any of the following optional con- trols: appliance-mounted (rocker switch) or wall-mounted switch, thermostat, or one of the optional remote control kits. If appliance- mounted ON/OFF control is selected mount it in the gas valve mounting bracket.

2. If wall-mounted ON/OFF control or thermo- stat is selected mount it in a convenient location on a wall near the fireplace.

3. Wire the control switch within the millivolt control circuit using the 15 feet of 2 conductor wire supplied with the unit. Caution: do not connect the optional wall switch to a 120V power supply.

4.Alternatively, the appliance may be operated without the use of the controls indicated in step 1, solely by manipulating the gas valve control knob. In order to use this method, twist the free ends of the two conductor wire (located inside the bottom compartment of the unit) together as shown in Figure 44.

Note: The supplied 15 feet of 2 conductor wire has one end of each conductor connected to the gas valve circuit and the other end of each conductor placed loose inside the bottom com- partment of the unit.

If any of the original wire as supplied must be replaced, it must be replaced with Type AWM105° C – 18 GA. wire.

Note: The supplied 15 feet of 2 conductor wire has one end of each conductor connected to the gas valve circuit and the other end of each conductor placed loose inside the bottom compartment.

B. Electronic Wiring (See Figure 45 ) –

Note: The electronic appliance must be con- nected to the main power supply.

1. Route a 3-wire 120Vac 60Hz 1ph power supply to the appliance junction box.

2. Remove the outlet box from the junction box by removing two screws .

3. Connect the black power supply wire to the lower outlet's red pigtail lead and the white power supply wire to the common terminal of the outlet as shown in Figure 46.

4. Connect the ground supply wire to the outlet's green ground screw.

5. Locate and install a low voltage (24V) wall switch or thermostat (not supplied) in the desired location.

6. Connect the low voltage wire to this switch or thermostat.

7.Insert the control circuit plug into the lower outlet box.

8. After wiring is complete, replace the outlet box.

Note: The gas valve-mounted ON/OFF switch is shown in Figure 45. It is integral with the gas valve.

Step 5. WIRING - OPTIONAL FORCED AIR BLOWER KIT (See Figure 45 )

4. Connect the ground supply wire to the outlet's green ground screw.

5.Reinstall the outlet box.

6. Insert the blower plug into the top outlet.

(The bottom outlet is unused on millivolt units, while the burner control circuit plugs into the bottom outlet on electronic units.)

IMPORTANT: Ground lead must be con- nected to the green screw located on the outlet box. See Figure 45. Failure to do so will result in a potential safety hazard. The appliance must be electrically grounded in accordance with local codes or, in the absence of local codes, the National Electrical Code, ANSI/NFPA 70- (latest edition). (In Canada, the current CSA C22-1 Canadian Electrical Code.)

An electrical outlet box is provided for the instal- lation of the FBK-100, FBK-200 forced air blower kits (optional). Electrical power must be pro- vided to this box to operate these blowers.

1. Route a 3-wire, 120Vac 60Hz 1ph power line with control switch to the lower right rear corner of the appliance.

2. Remove the outlet box by removing two screws.

3. Connect the supply wires to the blower
