Section 3: Recommended Power Supply Wire
Specifications
For 36EB110-GRT & 36EB111-GRC installations use three non-metallic
sheathed cables with ground wire for the power supply. Use the appropriate wires to
meet local and national electrical codes for rated power consumption.
For 36EB220-GRT & 36EB221-GRC installations use four non-metallic
sheathed cables with ground wire for the incoming power supply. Use the appropriate
wires to meet local and national electrical codes for rated power consumption.
Recommended Wire and Fusing Requirements
Use appropriate wire to meet local and national electrical codes for rated power
consumption. All wire gauges should be 12 gauge solid wires with a dedicated 15 amp
breaker for 120 volts. For 208/240 volts Builders Box models use two dedicated
15 amp breakers.
Allow at least 8 in of service cable for connecting power supply wire to junction box on
fireplace insert when installing before finishing wall. Allow up to 4 feet of service cable
for connecting power supply wire to junction box on fireplace insert after finishing wall.
