Chromalox PF421-6 Installation, Operation And Renewal Parts Identification

RENEWAL PARTS IDENTIFICATION
Type EH and HVT Electric Utility Heater
NOTICE: Carefully remove heater from carton and check for
shipping damage. Any damage claims should be entered
immediately with the carrier.
FIRE HAZARD. Since heaters are capable of devel-
oping high temperatures, extreme care should be
taken to:
A. Locate on vertical wall with length of heater positioned horizon-
tally. HVT models must be installed with thermostat at right end;
B. Avoid mounting into a wall recess since such mounting interferes
with free air circulation, increases heater temperatures, and pre-
vents proper thermostat operation on HVT models;
C. Mount heaters with a minimum clearance of 24" above floor level
or from adjacent wall;

screws (HVT models-5/16" diameter holes on 5" x 25-7/8") (EH
