Supply Connections Improperly Wired
Insufficient Service Loop on
Supply Connections
Electrical Short-to Ground

(Fan Operates at Reduced Speed Due to Current Loss)
Consult a licensed electrician. Ensure sufficient service loop in supply wires to maintain
secure electrical connections to rotate heater on bracket (particularly when using rigid or
semi-rigid conduit).
Consult a licensed electrician. Ensure Supply Connections L1, L2, L3 & Ground are secure.
(L3 only provided in certain models).
Consult a licensed electrician.
Ensure Adequate Wire Guage for Supply Connections.

per National & Local Electrical Codes.
Do not power off heater using circuit breaker. Fan motor is designed to operate for a
short period of time after heating element shuts off to prevent an overheat condition.
Disconnect power! Inspect Fan Blade (Rear of Heater) for foreign or dislodged object(s)
preventing rotation. Remove Rear Grille and clear interference, re-attach Rear Grille.
Remove any objects on heater or adjacent to heater vents. Do not block intake or exhaust by
columns, machinery, etc. Ensure 24 inches minimum distance from heater exhaust (front) to
any object.
Ensure heater is installed with sufficient clearance all-around
*8 feet minimun from floor
*8 inches minimum from rear of heater
*13 inches minimum from side of heater
Disconnect power!
Open Hinged Bottom Cover by removing retaining screw. Inspect Circuit Card Assembly
(adjacent to Supply Connection Terminal Block) for loose or detached "plug-in" electrical
