there are no instractions on this heater at all so here what i see
MARLEY heater model# PLF1504D input voltage 220volt AC 6.3 Amps Honeywell thermostat 220 volts AC
what i need to know is do i need 12/2 or 12/3 or 10 gage wire to install the heater also no information if the double pole breaker sould be 20 or 30 Amps
the hot lines coming forn the electrical box will go to LINE 1 and LINE 2 to the thermostat and then T1 and T2 from thermostat to the heater
there is no ground on the thermostat so i assume that it will be connected directly the ground fron the box to the ground of the heater
can you give me any information to my questiosn about the breaker and the wire gage?

thank you
