INSTALLATION & OPERATION
1). THERMOSTAT LOCATION
For accurate temperature control and comfort, correct location is very important.
On new installations, the guidelines listed below should be followed as closely
as possible. When replacing an old thermostat, install the new one in the same
location unless these conditions suggest otherwise.
1. Locate the thermostat on an inside wall about five feet above the floor,
where it is easy to install and adjust. It should be in a room that is used
often, such as a family room.
2. Do not install it where there are unusual heating conditions, such as direct
sunlight, close to a lamp, radio, television, radiator, register, near a
fireplace, or other heat producing appliance. Also, check for hot water
pipes within the wall, or a stove on the other side of the wall.
3. Do not k:x:ate in unusual cooling conditions, such as on an outside wall, or one
separating an unheated room, or in drafts from stairwells, doors, or windows.
4. Do not locate in a damp or humid area. This can shorten thermostat life
due to corrosion.
5. Do not locate where air circulation is poor, such as in a corner, alcove, or
behind an open door.
6. Do not install until all construction work and painting have been completed.

2) TOOLS REQUIRED
Wirestripper or knife, drill with 3 /1s" bit, screwdriver, level and a pencil.
3) REMOVING OLD THERMOSTAT
Please read all instructions carefully. As you complete each step, check the
adjoining square G;i'.
D Disconnect electricity and turn off gas to the heater.
D Remove cover from old thermostat.
D Loosen all screws.
D Disconnect wires from thermostat, making sure they
the wall.
D Strip insulation%" from wire ends and clean off any corrosion.
D Fill wall opening with non-combustible insulation to prevent drafts from
affecting them10stat.
4) INSTALLING NEW THERMOSTAT
D Place new decorative wall plate (if supplied), Figure 3, over wall opening.
Decorative wall plate can optionally be left off.
0 Remove Front Cover of new thermostat by inserting a finger in the side of
the thermostat and gently prying away each corner. Place Base, Figure 2,
on wall plate over wall opening. Mark wall with pencil at mounting holes as
shown in Figure 2. Now lay wall plate and base to the side.
Drill two holes with 3 /15' bit, 1" deep.
D
D Insert plastic screw anchors into drilled holes, flush with wall surface.
D Bring wires through large hole in decorative wall plate and through Hole
For Wires in Base.
D Fasten Base loosely to wall using two mounting screws. Place a level
against the bottom of the Base, adjust until it is level and then tighten
mounting screws to secure the Base.
O Attach wires to terminal screws shown in Figure 2. (Either wire to either
terminal) Push excess wire back into wall opening.
O Find anticipator setting on old thermostat. Setting on new t � ermostat
should be the same. Do this by carefully sliding the long pointer on the
anticipator over the desired number. If old anticipator setting cannot be
determined, look on gas control on furnace, or set it at .6. Dur � ng heating
season, furnace should operate about five times an hour. If ad1ustments
are necessary, move heat anticipator pointer slightly and recheck. NOTE:
