TOOLS REQUIRED

PARTS OF YOUR HEATER

TIPS BEFORE YOU BEGIN

• Verify power has been turned off before starting any work!
• Model CS can be mounted with the element up, or with the element on the left. For ceiling installation, see page 5. For multiple heater wiring, see page 6. All the fan-forced heaters have a minimum clearance of 10″ (25.4 cm) from the ceiling and 4′ (1.2 m) from sprinkler heads.
• Model CST can only be mounted with the elements up. It cannot be mounted in the ceiling.
• For cleaner performance and longer heater life, install your heater 12 inches (30.5 cm) from the floor.
• All models can be installed to be Americans with Disabilities Act (ADA) compliant. Check your state and local requirements.
• A thermostat is required for models that do not come with a built-in thermostat. An electronic wall thermostat is recommended for ultimate comfort and energy savings.
• The wall can label arrows show the correct mounting orientation (arrows must point up).

STEP 1: CUT A HOLE IN THE WALL NEXT TO A WALL STUD

If you haven’t installed drywall yet, skip this step.

STEP 2: LOCATE OR ROUTE ELECTRICAL SUPPLY WIRES

If you’re wiring a wall thermostat, route the electrical supply wire from the circuit breaker to the wall thermostat, and then to the heater location. If your heater has a built-in thermostat, route the electrical supply wire from the circuit breaker directly to the heater location.

Remove a knockout from the wall can and attach the supply wire with a cable clamp connector (not included) leaving a minimum of 6 inches wire lead (See Figure 3).

STEP 3: MOUNT THE WALL CAN

If you haven’t installed drywall yet, make sure the front of the wall can extends beyond the front edge of the wall stud to match the drywall depth (Figure 3).

If you already have drywall installed, place the can into the cutout so the front is flush with the drywall.

Fasten the wall can to the stud with 2 screws (Model CS) or 4 screws (Model CST) (not included), through holes provided in the wall can (Figure 3). As an option on model CS, the foam pad provided may be attached to the side of the wall can to square the wall can to the stud (See Figure 3).

ATTACH FOAM PAD HERE (MODEL CS ONLY)

INSERT THE HEATER ASSEMBLY IN THE WALL CAN

STEP 4: WIRE CONNECTIONS

1. Your heater has two connection wires on the back. Your supply wire has two connection wires and a supply ground wire.
   • Connect supply ground wire to grounding screw in wall can (See Figure 4 or 5).
   • Connect one supply wire to one heater wire with a wire connector (not included):
   • For 240 or 208 volts, it doesn’t matter which heater wire. Both supply wires (black and white) are hot. Wrap supply (white) wire with black tape to identify it as hot (Figure 4).
   • For 120 volts, connect the neutral (white) supply wire to the white heater wire (Figure 5).
   • Connect the remaining supply wire to the remaining heater wire with a wire connector (not included) (See Figure 4 or 5).
2. Turn the heater back around and insert the bottom edge of the heater assembly into the D-shaped tabs at the bottom of the wall can.
3. Push all wires back into the bottom of the wall can. Make sure connections are tight and that none of the wires are caught between the motor and the wall can.
4. Attach the heater assembly at top of the wall can with screw provided.

STEP 5: INSTALL GRILL

Attach grill with screws provided. If you have a built-in thermostat, slide thermostat knob onto shaft. If you have a model without a thermostat, snap in the grill plug provided. Turn power on at the main disconnect panel.

Proceed to OPERATING INSTRUCTIONS.

CEILING MOUNT (MODEL CS ONLY)

STEP 1: MOUNT THE WALL CAN

IMPORTANT:

1. Only for Model CS up to 1,500 Watts – MAXIMUM
2. Do not mount the heater in low density fiberboard or false ceilings.
3. Models with a built-in thermostat are not recommended.

Fasten the wall can to ceiling rafters on any two sides (See Figure 6) with a minimum of 4 screws (not included). You may need to install an additional rafter perpendicular to your ceiling rafters. The front edge of the wall can must extend beyond the front edge of the ceiling rafter(s) to match the drywall depth.

STEP 2: ROUTE SUPPLY WIRES

IMPORTANT: Supply connections must use wires suitable for at least 167˚F (75˚C) in the ceiling.

Route the electrical supply wire from the circuit breaker to the wall thermostat, and then to the wall can. Remove a knockout from the wall can and attach the supply wire with a cable clamp connector (not included) leaving a minimum of 6 inches wire lead (See Figure 3).

Continue to STEPS 4 and 5 above.

MULTIPLE HEATERS WITH ONE THERMOSTAT (MODEL CS ONLY)

More than one heater can be wired in parallel on the same circuit breaker (be sure to check national and local codes for safety requirements). Additional electrical supply wire and cable clamp connectors are required, and you’ll need to use a wall thermostat. When wiring multiple heaters to one thermostat, the heaters must be in the same room and be spaced a minimum of three feet apart.

The maximum amperage load you can put on one circuit breaker is limited to either 80% of the circuit breaker capacity, or the maximum amperage rating of the thermostat, whichever is lower.

1. Route the electrical supply wire from the circuit breaker to the wall thermostat. At the wall can of heater #1, attach two sets of electrical supply wires with two cable clamp connectors (not included), leaving a minimum of 6 inches wire lead. One set of electrical supply wire goes to the wall thermostat and the other set goes to heater #2 (See Figure 7).
2. There are two supply ground wires in the wall can of heater #1. You’ll need to add a small piece of copper wire (not included) to make the 3-wire connection with the ground screw (See Figure 7).
3. For heater #1, connect each heater wire to one of the supply wires going to the thermostat, and to one of the supply wires going to the heater #2. Both wires from heater #1 must have a 3-wire connection.
4. For heater #2, make the connections in the wall can as shown in Figure 7 above. Proceed with STEP 4 Wire connections, number 2 on page 5.
5. Turn power back on at the main disconnect panel.
6. Proceed to OPERATING INSTRUCTIONS.

OPERATING INSTRUCTIONS

1. Make sure all wires are properly connected and installation is complete before you turn on the heater
2. Do not operate without grill.
3. Do not tamper with the high temperature safety shutoff.

COMPLETE INSTALLATION

After installation, turn your heater to the highest setting and let it run for 30 minutes. Some smoking may occur as the element initially burns off residue from manufacturing.

If your heater shows signs of overheating, such as glowing red or repeatedly getting unusually hot and shutting off, immediately turn off the circuit breaker and review the “KNOW YOUR VOLTAGE” section or call us.

If the high-temperature safety shutoff trips more than once a day, replace the heater.

HOW TO OPERATE YOUR HEATER

The room temperature is controlled by a thermostat located either on the wall, or on the heater. Once installation is complete and power is on, follow the steps below for your thermostat.

If you have a wall or built-in thermostat with a knob:

1. Turn the thermostat knob all the way to the right.
2. When the room reaches your comfort level, turn the knob to the left, just until it clicks and the heater turns off. The heater will automatically keep the room temperature around this setting.
3. To reduce the room temperature, turn the knob to the left. To increase the room temperature, turn the knob to the right.

If you have an electronic wall thermostat, follow the instructions in the programming and operating guide included with your thermostat.

FAQs

How loud is this heater?****

I have used these Cadet heaters in several houses and like them a lot. They are relatively quiet. You can hear the fan and the air flow, but I have never thought they were too loud or annoying.

does it come with a filter?****

No. This does not use a filter.

Can this heater be mounted sideways, or does it need to be mounted up and down?****

It needs to be mounted vertically only.

It shows pics of wall can coming with it but then for an extra 3 dollars it says I order it with a wall can and is not prime. So which is it****

Box I ordered came with can but no containment box to fit between studs.

In a very small bathroom, can this be mounted 5′ from floor? Any issues with going higher, like system turning off as heat rises or not heating floor?****

this item is not intended to be used in the bathroom at all. We do have a comparable model specifically for the bathroom. The CBC103TW is a 1000 W 120V bath heater. This item is made specifically to heat your bathroom and keep you comfortable.

Will this heat an 8×27′ RV in a new York winter where it can get to -30F?****

This is really meant for small spaces (bathrooms, small house additions, etc.). I doubt it will heat a whole 27′ RV efficiently at -30F. I bought this to replace our previous heater that went bad in an addition to our garage.

Can I use this to replace my old baseboard heaters with the same wall thermostat?****

For safety reasons- I would definitely call customer service at Cadet!!

can this unit be use in a bathroom were moisture and steam is present?****

Absolutely! I bought it for a tiny bathroom that my wife likes to steam the heck out of. This little heater helps burn all of that off.

Can this be hooked to a thermostat on a wall****

No, it can’t be hooked to a thermostat but it has its own setting. I would recommend it because it is a very reliable heater. I have installed it in all of my apartments and I seldom have problems with it.

Can the face plate be painted?****

No, we do not recommend that you paint the grilles on our heaters. They are finished with a baked on powder coat, painting over this will void any warranty on the heater.

This unit will not turn off. I turned it all the way ccw and no click and still runs. I hope this reaches the manufacturer, not sure if bad thermostat****

I was able to turn mine on for about 10 seconds, then done ,toast….paid a licensed electrician to install and it blew.

Can you get a surface mount kit for this heater?****

Yes, there is a surface mount wall can available for the Com-Pak series. In white it is model #CCSMW.

Is there a good cover that will allow full use of the unit but will also be safe to the touch for children?****

Unit has the grill pictured which is metal and will get hot. Not sure how to protect child’s hands. Also simply rotating the control will activate heater.

Can this be mounted in the bathroom ceiling using the recessed lighting wire connection?****

They are for wall mount only.

Where I would like to install it my 4″ abs plumbing stack would be directly behind it. would the heater effect the abs. plastic?****

I can’t imagine it causing a problem.
