when making external circuit connections to the 

orange and white line voltage burner and ignition 

leadwires of the R8182H,J.

WARNING

Electrical Shock Hazard.

Can cause severe injury, death or property 

damage.

Disconnect power supply before wiring to prevent 

electrical shock or equipment damage.

All wiring must comply with local codes, regulations, and 

ordinances.

IMPORTANT

Terminals on the R8182 are approved for copper 

wire only.

Follow the wiring instructions furnished by the appliance 

manufacturer, if available, or refer to Fig. 11 through 17. For 

wiring multiple zoning systems, refer to Fig. 16 and 17.

The R8182 is equipped with special wiring terminals. Wires 

can be wrapped around the terminal screw or inserted from 

the side.

Method 1

1.

Strip 7/16 in. of insulation from the wire end.

2.

Wrap the wire 3/4 of the distance around the screw as 

shown in method 1.

3.

Using a standard, flat-headed screwdriver, tighten the 

screw until the wipe is snugly in contact with the screw 

and contact plate.

4.

Tighten the screw pin an additional one-half turn.

Method 2

1.

Strip 5/16 in. of insulation from the wire end.

2.

Insert wire beneath the screw as shown in method 2.

3.

Using a standard, flat-heat screwdriver, tighten the 

screw until the wire is snugly in contact with the screw 

and contact plate.

4.

Tighten the screw an additional one-half turn.

NOTE: Do not use a push-type ratchet screwdriver.

The TRADELINE® R8182D,H can be converted to replace an 

R8182B,C,E,F or a White Rodgers 6C92-2 or 6C92-3. When 

replacing a White Rodgers model, the immersion well must 

also be replaced. Refer to Fig. 10 for Aquastat® limit 

connections necessary for each R8182D conversion. 

To release the wires from the R8182, insert a screwdriver into 

the rectangular hole adjacent to the wire, push inward to 

release the locking-grip on the wire, and pull the wire out of 

the terminal hole. 

To reinsert the wire into a new terminal hole, simply push the 

wire into the new slot.
