Install Wall Heater With a Built-in Thermostat
Whether you have a few questions during an installation or are doing pre-purchase research, this video will show you the basics of how to install a wall heater with a built-in thermostat.
This video features our Com-Pak heater, but the process will be almost identical for any wall heater with a built-in thermostat.
Step 1
Be sure to check your Owner's Guide for your specific heater's cutout size and clearance requirements.
Step 2
Cut a hole in the wall, next to a stud.
Note: The Com-Pak heater needs to be installed a minimum of 4.5 inches from the floor, and it needs to have 3/4 inch clearance on either side of the grill.
Step 3
Find a stud and mark it with a pencil.
Tip: Cut a small hole to make sure your line is right against the stud.
Step 4
Trace an outline for the heater that’s 10 and 1/8 inch tall by 8 inches wide and cut along the outline with a drywall saw.
Step 5
Once your cutout is made, the next step is to get ready to run the circuit.
Step 6
Set up a new line inner panel and make sure your heater matches the voltage of your circuit.
Step 7
From the breaker panel, route the wire to your wall can and don't forget to turn off your breaker before you do anything else.
Note: If you feel uncomfortable doing this work, or doing the installation of the wiring, have an electrician help you.
Step 8
Next, install the wall canister:
-
Attach the foam pad to the side of the wall canister that will rest against the stud
-
Remove a knockout from the wall canister
-
Install a cable clamp on supply wires
Tip: leave at least 6 inches of wire to make heater connections
4. Attach the cable clamp connector to the wall canister
5. Attach the wall canister to the stud
Step 9
Next, wire the connections, make sure your cable clamp is in and tight.
Tip: Leave about a half inch of insulation.
Step 10
Cut this back to get the wires ready and indicate which wire is hot.
Note: 240 Volt instals only - cover white wire with black electrical tape. If you're doing a 120 volt heater, you would leave that alone indicating it is a neutral wire.
Step 11
Attach the ground wire to the grounding screw.
Step 12
Connect the supply wires to the heater with wire connectors.
Note: 120 volt only - connect the white heater wire to the neutral supply wire.
Step 13
The last step is to install the grill:
-
Attach the grill
-
Attach thermostat knob
-
Turn the breaker back on

0:02 We're here to show you how to install a wall heater with a built-in thermostat.
0:06 Today, we're going to install a Com-Pak heater.
0:10 The process is pretty much the same as our other wall heaters.
0:13 Be sure to look at your specific owners guide for the model you're installing to find out
0:18 The cutout size and the clearance requirements.
0:21 To install a wall heater you're going to need to: Cut a hole in the wall, next to a stud.
0:25 Locate or route electrical supply wires.
0:28 Install the wall can.
0:30 Wire connections.
0:31 And install the grill.
0:32 The Com-Pak heater needs to be installed a minimum of 4.5 inches from the floor, and
0:37 It needs to have 3/4 inch clearance on either side of the grill.
0:41 However, for ease of use, we're going to go ahead and install the heater about here.
0:45 Ok, we're finding a stud here now.
0:47 We're going to go ahead and mark that with our pencil here.
0:52 We're able to cut our hole so that our can is next to the stud on either the left or
0:56 The right.
Tip: cut a small hole to make sure your line is right against the stud
Trace an outline for the heater that’s 10 and 1/8 inch tall by 8 inches wide
Cut along the outline with a drywall saw
1:09 Ok, so we got our cutout made, now we're ready to run the circuit.
1:25 We're going to have to set up a new line inner panel.
Make sure your heater matches the voltage of your circuit
1:29 From the breaker panel route the wire to your wall can.
1:32 If you feel uncomfortable doing this work, or doing the installation of the wiring, have
1:37 An electrician help you.
1:39 Don't forget to turn off your breaker before you do anything else.
1:42 Ok, now we're going to install the wall can.
Attach the foam pad to the side of the wall can that will rest against the stud
Remove a knockout from the wall can
Install a cable clamp on supply wires
Tip: leave at least 6 inches of wire to make heater connections
Attach the cable clamp connector to the wall can
Attach the wall can to the stud
2:30 Next, we're going to wire the connections.
2:32 Ok, we got our cable clamp in and tight.
2:35 What we want to do is leave about a half inch of insulation still there, so I'm going
2:38 To go ahead and cut this back so we can get back to our wires.
2:45 Ok, we got our wires here all ready.
2:47 We're actually going to be doing a 240 volt heater today, so we have a white wire here
2:52 We want to indicate as hot, so we're going to wrap that with black tape.
240 Volt installs only: cover white wire with black electrical tape
2:56 If you're doing a 120 volt heater of course you would leave that alone indicating it is
3:23 A neutral wire.
