Electric ceiling heater wiring question

[jvitez]

I'm going to install this 5000 W ceiling heater in the garage:

Ceiling with be drywall, wire is 10 gauge NMD. I'm in Canada so under the CEC not NEC.

My question is how to terminate the wire at the ceiling. Do I need to install a device box to clamp the sheath, or can I simply poke the NMD through the drywall itself? I know the latter is allowed for light fixtures, but how about a large load like this heater? The installation instructions only say "Run the electrical supply cable up to the wiring compartment of the unit." Connections are done inside the unit, so no external AC wire needed like a wall hung unit heater.

Experience and advice is much appreciated!

Not a CEC expert but it would seem to be OK to connect it as planned as long as the temperature rating of the cable complies with listing requirements.

Poke the cable through the drywall. just like a regular baseboard.
I'm in quebec and that's how i did and the electricien had nothing wrong to say.
(I went through a steel door cutout( piece of door cut to install the windows) and put a grommet in itbecause it's steel but other then that it was all fine to just go through the drywall.)

use a plastic or screwed connector to bring the wire inside the heater.

Sounds good. Thanks gents.

The heater has 2 knock-outs in the top of the wiring compartment, so I'll be able to clamp the cable there.

A wall mounted unit heater might have been a bit easier to wire but I wanted to maximize usable wall space. This heater is more expensive than a unit heater, but it's made in Canada not China, and I got a small discount at Rona as their shelf price was mis-labeled. I even bought a Stelpro thermostat to keep it all in the family.

Thanks again gents.

As long as the unit is rated to be directly mounted to the ceiling, I can't see a problem with just poking the NMD through the drywall and using a suitable connector in one of the knockouts.You may have got a sweet deal at the store,sadly your power bill will eat up your savings in a few hours!

Yeah, I know it won't be cheap to run but it's only for intermittent use. Electricity was cheap until we spent billions on a dam and power lines we don't need......

Thanks for the confirmation tfi. I appreciate hearing from a Canuck pro.

The unit is made to be directly mounted to the ceiling or suspended.

Stelpro are overprice for what they are really .

Whish are made in china too.

I have a older Uberhaus (rona home brand made in china) and it's in everyway identical.
Same goes for the homewell(you read right..not honeywell) and the EnerG at costco for the only difference been the shape of the vent fins.
All of those are selling for less then 150$ (compare to the Stelpro at more then 400$)

I checked the Stelpro carton and it says Made in Canada. I agree it does look like a pretty basic unit, but really all electric heaters are pretty basic.

I try and support Canadian and US manufacturing as much as possible. I'm forced to buy made in China on far too many things already, so I "put my money where my mouth is." I don't mind paying extra to support our two countries. I feel better knowing the heater is made by fellow Canucks (well, Quebecer's in any case ) than by 2 dollar an hour sweat shop Chinese labour.

Rona's website has the Homewell ceiling heater at $149, and a Dimplex unit on clearance for $299. The Dimplex is also made in China, so if the choice was between these two the Homewell would be a no-brainer.
