Marley Hydronic baseboard heater not turning on

can't find a contrl knob for my marley wall heater model # fzl3004b

I need a control knob for my Marley electric wall heater model#fzl3004b

the thermostat could be bad or the wires are not wired right to the thermostat or at the heater.

c...

you have to be sure supply wire is able to handle total amp draw.it should be 10 gage.if it is,without getting too technical youre fine.

Two wires to the T-stat should go to W and C which is W for heat call and C represents common!
When the T-stat is set to heat it will connect the 24v red wire to the W terminal therfore sending 24v to the heater and the common wire completes that circuit. Make sure to use an inline fused wire to test so you do not blow your transformer. Easier to replace a fuse then a T-form

My PLF504 detonated this morning (11-25-2010). It worked fine for two years then BANG. Room was lit by flame coming from center (left to right) of unit. I wrote Marley asking them to honor the 10 year heater element warranty. Also, no burnt wires at thermostat connection, no dust bunnies on the fins. Source of fire was the fluid filled encapsulated heater core. Thank God, circuit breaker tripped and wall was tiled.

that is up to u only problem is after they go out of business u wont be able to get parts so dont be surprised if u have to replace it after a while good point is most parts are universal and u can get some parts for it so i think u will be fine

These are only 1500 watt heaters.

They 'could' heat a 20 x 20 foot room (with good, tight construction), with a slow temperture rise.

Hello,
I believe you interpretation of the code is a bit skewed in that the fundamental concern is to not route power cords over a heat source which might cause the insulation on that wire to exceed its rated operating temp and fail. The heaters themselves have shrowds over them so there are no exposed surfaces hot enough to melt wire insulation and when you think about it ..2000 watts disipated over a long baseboard section is not that hot. If I were you, I would go ahead and install them and not worry about the warning.. The warning also removes any liability from the heater manufacturer in the event something happens.. Common sense would dictate that you wouldn't intentionally drape power cords all over the heaters... Just use common sense and not worry about it..
Regards,
Rick

The Black Wires from the md26 are your load(the heater) and the red lines are your line(power). The lines are also paired up on the thermostat with a red and black on the left and are red and black on the right. In the actual heater connect the black to the black wire and the white to the white and connect the grounds. In the thermostat connect the black from the heater to left side black( remember there are pairs left(black, red) right (black, red) and the white to the right side black connect the black from your power to the left side red and the white from your power to the right side red. Should be ready to go.
