ELECTRIC FORCED-AIR HEATER
MODEL TSH20J

THIS HEATER IS DESIGNED FOR MOUNTING IN THE KICK SPACE OF KITCHEN AND BATHROOM CABINETS. IT MAY ALSO BE MOUNTED WITH THE GRILLE IN A VERTICAL POSITION INSTEAD OF THE HORIZONTAL POSITION AS SHOWN. THE HEATER MAY BE USED WITH A WALL LINE VOLTAGE THERMOSTAT OR WITH A BUILT-IN THERMOSTAT ACCESSORY KIT MODEL(S) TSH1TX (SINGLE POLE) OR TSH2TX (DOUBLE POLE).

OPERATING INSTRUCTIONS

THE THERMOSTAT CONTROL CAN BE EITHER THE WALL TYPE OR BUILT INTO THE UNIT ON THE LEFT SIDE OF THE GRILLE. IT SHOULD BE SET TO THE POSITION THAT GIVES THE DESIRED COMFORT LEVEL IN THE ROOM.
CAUTION: DO NOT OBSTRUCT THE FRONT GRILLE OF THE HEATER SINCE THE PROPER OPERATION OF THE HEATER REQUIRES A FREE FLOW OF INTAKE AND EXHAUST AIR.

THE HEATER HAS A BUILT-IN MANUAL RESET THERMAL PROTECTOR WHICH PREVENTS OVERHEATING IF THE GRILLE OF THE HEATER IS ACCIDENTALLY BLOCKED.
