DANGER
ELECTRIC SHOCK OR FIRE HAZARD
READ CAREFULLY - These instructions were written to help prevent diffi culties that might arise during installation of this
heater. Studying the instructions fi rst may save you considerable time and money later. Observing the following procedures
will cut the installation time to a minimum. King encourages you to save these instructions for future reference.
Thank you for buying this King H series heater. It should provide years of trouble-free service and comfort to your home.
Please inspect the package to ensure the heater coil and fan, with cover and screws to attach it to the wallbox, are included.
Here are a few tips in getting the heater installed correctly!
1. LOCATION: If possible fi nd a location that is not on an outside wall - this will maintain the insulation value of your home and reduce cold air
leaks that come from gaps in the outside wall. Mount the heater in a location that will not have furniture blocking the front of the unit within
2 feet - a corner wall is ideal. Blowing heat towards the coldest part of the room (like a window) is best. To heat the room evenly warm air needs
to circulate freely without obstructions.
2. BEDROOMS: A good location for a heater in a bedroom is just to the inside of the door of that room, blowing heat towards a cold glass window.
The thermostat should be located just above the light switch, with the heater in a stud bay over from the thermostat. Many times this one
stud bay over is not possible due to very small bedrooms, where the thermostat will be in the same stud bay as the heater. Temperature control
and accuracy will suffer in this instance due to the coils giving off convected heated air, the heated air moving up the wall where it will then effect
the thermostat’s sensors.
3. LIVING
ROOMS: Mount the heater in a location that will not have furniture blocking the front of the unit within 2 feet. Often, a corner wall is ideal
because it is a traffi c area with less chance of furniture placement. Blowing heat towards the coldest part of the room (like a large window area)
is best. Mount thermostat near a light switch for that room if it is in an open area.
4. MOUNTING: The heater should be located a minimum of 4 inches off a fi nished fl oor, although, to dramatically reduce the lint and dust intake,
up to 10 inches off the fl oor. However, too high placement on a wall may change the visual appearance of the product. King further recom
mends placement 4 inches from any side wall longer than 18 inches, and 8 inches below a ceiling or shelf that protrudes more than 6 inches.
5. THERMOSTATS: Only King model HB / HBP or HW / HWP / HWPT-120 thermostats are designed to control this heater. Any other line voltage
electric heat thermostats will not control the pump and fan in a sequential preheat start up, nor have a defi nate off for both fan and pump.
Standard bi-metal electric heat thermostats are not designed for, and should never be used for, control of hydronic fan heating. A King
H series thermostat should not, when possible, be mounted above the fan coil heater, instead off to the side, where the convective heat from the
coils will not effect the temperature sensing when the fan heater is off. For best performance, pipes running to the heater (if they enter in to the
thermostat’s stud bay) should not have a total combined length (inlet / outlet) of over 10 feet, and, should not be closer than 16 inches in
any direction the the thermostat’s junction box in that stud bay. If the thermostat must be in the stud bay with the heater the thermostat should
be mounted on the left side of the stud bay as that side has no heat fi ns thereby having the least impact on thermostat accuracy.
