Technical information
INSTRUCTIONS:
*1. Drain and flush radiator and block.
*2. Remove correct frost plug or core plug - depending on type of
engine.
*3. Clean frost plug hole with a cleaning agent to remove any dirt,
grease or paint. (Lubricate “O” ring with a light weight grease only,
oil is not as satisfactory) before installing heater in frost plug
opening.
*4. Place engine heater in frost plug opening. Position of element is
dependent on specific engine. The shoulder on the steel section of the
heater must be against the face of the engine block wall. This allows
the “O” ring to seal the unit for a leak proof installation.
*5. Models with a toggle or flat cross bar on the back side of steel
adapter must be installed with bar behind block wall. Tighten the Hex
head or nut to 15 to 18 inch pounds torque until the cross bar is tight
against inside block wall. Only use these models where
recommended. (see example B above.)
*6. Models with a curved cross bar need to be torqued to 80 to 90
inch pounds to expand the cross bar on the back side of the heater in
the frost plug opening. Only use these models where recommended.
(See example A above.)
*7. Models with a butterfly cross bar need to be tightened to 14 to 19
inch pounds. Only use these models where recommended. (See exam-
ple C above.)
*8. Place the electric cord from the heater through radiator grille or
other convenient opening and tape or fasten in position, making sure
it is clear of all moving parts (fan blades) and heater parts (manifold).
*9. Refill radiator, run engine long enough to build up a maximum
pressure and check for leaks to complete installation.
10. Connect the Katʼs Engine Heater to any 120 volt AC or DC elec-
tric outlet. Use your heater for 60 minutes or longer before vehicle is
to be operated. Heater can be left on all night without overheating.

certain that the wire size of the extension cord is of adequate size for
the wattage of the heater and distance from the receptacle to the
heater Consult a licensed electrician if further information is required.
