Hello and thank you for contacting us. The power cord is on the right side of the unit, facing.
The power source length would vary depending on the Btu's of the unit and the power source. For further information, you may contact our Customer Service at 800-243-0000. Also, some other information to keep in mind:
Preparation for Operation:
1. Plug in the power plug properly.
2. Use a dedicated circuit. Overloading the line could create a fire hazard.
3. Do not use an extension cord [see page 10 of Owner's Manual for more details]
4. If the power cord is damaged and requires replacement, have an Authorized Servicer install an
exact replacement part.
