AC Power Requirements
WARNING: Label all wires prior to disconnection when servicing controls. Wiring errors can cause improper and dangerous
operation. Verify proper operation after servicing.
For blower operation, 120 VAC, a 2 Amp power source is required . The AC power supply to this Fireplace
insert must be hot at all times and shall not have a switch installed in it.
This appliance is equipped with an electrical junction box on the left side.
1.
Place connected wire ends within junction box then close and secure the junction box cover plate.
AC Power Connection Option
Two options exist for supplying 120 VAC power to this appliance:
1.
Run the 8-foot extension cord connected to the blower circuit out of
the fireplace insert cavity to a wall electrical outlet in the room.
2.
Install an electrical outlet (inside a metal junction box with metal
faceplate) inside the wood burning fireplace insert cavity.
Always use metal flex conduit encapsulated 14 -2 cable
(MC Cable) to run power from the source to the outlet
junction box. Installation of the electrical outlet and its
electrical supply cable must conform to all local electrical
code requirements.
3.
For this application, roll the 8' extension cord in a tight loop and
place the loop inside the lower convection chamber of this
appliance. Plug the extension cord's 3-prong plug into the newly
installed junction box.
Notice: Mendota wants to make you aware of current NEC
Codes that may be enforced by local authorities. Mend ota
cannot over-ride local building officials' enforcement of
National Electrical Codes. Be aware of these potential
requirements.
Notice: Electricity circuits cannot be shared between different
floors within a home. This means that you can run a power
cable from a basement to the main floor fireplace insert through an ash cleanout opening or by drilling a
hole through. However, you cannot tap the power directly from a power circuit in the basement that
supplies power to basement lights or outlets. You must run a dedicated power circuit from the main fuse
panel to the upper level fireplace insert
Notice: An MC Cable which enters an electrical junction box must employ a strain relief clamp at the entry
point permanently to prevent movement, vibration and disc onnection or loosening of electrical connections
inside the Junction Box. Not using a strain relief clamp can lead to arcing between loose connections and
pose a fire hazard. If an outlet is installed inside a wood burning fireplace insert always use a metal junction
box, MC Cable and strain relief clamps.
