Rinnai Convector 404

Hey peoples,
Not sure how serious this problem is but from other responses posted here it looks like I've come to the right place.
As the subject would suggest I have a Rinnai Convector 404(gas heater), which I purchased last year from a garage sale. Unfortunately, it didn't come with a manual, and I'm finding it rather difficult to track the right manual done.
Essentially, when I try turning the heater on, the ignition light comes on and it sounds like the gas is kicking in...however, it seems like it can't maintain it.
It shortly shuts off, the fan sounds like it cuts off and there is a high pitched ringing sound. There are no lights etc that come on at this stage..(ie/ the filter light doesn't flash on).
I have checked the filters at the back of the heater and brushed them off. (Although there was very little dust there in the first place?)
I can manage to turn the heater on after about 5 or 6 attempts...but not knowing what's actually going on with it seems rather dangerous to my way of thinking...
Any suggestions would be greatly appreciated 8)

Hi pinkinfinite,

The 404 is a great heater. I am assuming it is a Natural Gas Heater. All it needs is a good blow out with compressed air. They tend to carbon up in the pilot light area. You will probably also find it is very dusty inside. Easiest way to clean the carbon out is to remove the hose at the heater and with compressed air blow through the fitting where you have removed the hose. Make sure you hold down the start button so the air can get through to the pilot light and jets. Don't connect the electricity for the fan when you do this.
To clean it out internally you only need to remove the front panelling. There are two screws holding the top panel (not to be confused with the side and top). The screws are located inside the bottom grill at the front. There are also screws for the bottom grill there which you will also need to remove and probably best to remove the bottom panel that house the front feet. It should expose all the inside workings of the heater except for the pilot light and jets etc. You should be able to see the fan - it is round and looks like a filter and sits behind the vent section. Make sure you give it a good blow out - it gets all dirt and dust around it. When you do it remove both the rear filters/covers. They are mesh. Blow the top one which is the larger metal one and make sure you blow inside where it fits over to remove the dust and dirt. Same with the other one which should be plastic with mesh. Once you do this put it all back together. Make sure all wires are connected and be wary with the compressed air as it may blow the connectors off from loose fitting parts. Once you get it all back together Test it and hopefully it should work. Hope this helps. I did one the same today that was having trouble starting and it now works like a new one.

    No worries - glad to be able to help. Most heaters work the same way and nine times out of ten it relates to the pilot light or jets that carbon up or are dirty. During winter often heaters get a bit of moisture in them from non use and being stored. A blow out before you use them often helps. When you finish doing the 404 you may find it will take a couple of goes to get it going again - it's just till the gas gets through the piping and then it should be ok.

    Good luck with it.

Is it cheaper to leave my heaters on?

It works both ways if you are home it will give a constant heat , but is it safe in your place to leave it on while you are out .
Once they are hot they should cut out on the thermostat thus costing less to run .

I have installed a Dimplex 1500watt heater. I used a double 15amp breaker and 14/2 wire (I know should've used 12 guage but changed plans post construction and was told 14 would be fine). There is...

A number 12 copper supply cable at the voltage is overkill for this load.

Ohm's Law states: Watts = Volts x Amps. To find Amps: Amps = Watts / Volts. This is 1500W / 240V = 6.25 Amps. Since the max continuous load for a 14 copper is 12 Amps, this size wire is the correct size.

Check to make sure the heater is in fact a 240 volt type, as if it is a 120 volt type, you are likely instantly burning out the heating element. If it is indeed a 120 volt heater, you will need to connect to a single pole 15 amp breaker and place the other wire that was on the breaker to neutral to provide the correct voltage. The load will still be 1500W, but at half the voltage, the current will double to 12.5 amps, and may cause the circuit breaker to trip after a while.

I hope this helps & good luck.

I'm looking to buy a clairion convector 1500 used if possible don't have much money i live near Mont-tremblant quebec

Apparently, the model you're looking for has been discontinued by the manufacturer. Not sure of the reason why, but we've had a lot of problems posted here on FixYa regarding them. However, there are other models available, by a different manufacturer, that are very similar to the Clairion HC-1500. And they are not expensive. Good deals abound on Ebay. Search for one there under Convection Heaters (All Ebay Categories)

Hope this helps you find what you need.

Hi, I don't know what the reset switch on my dimplex ofc2000ti looks like, anyone any ideas? Power to unit but not heating up, all connections inside fine. Hopefully it overloaded and tripped.

Turn the Master On/Off Switch to OFF and unplug the unit from the wall receptacle. Leave it unplugged for 12 - 15 minutes. That should give it enough time to reset itself. Then plug it back in and give it a try. Also, make sure that the wall receptacle is working properly and hasn't tripped the circuit breaker in your home's circuit breaker panel. If it did, something is seriously wrong electrically, with the heater.

Hope this helps you solve the problem. Please don't forget to rate my response to your question.

I have a goodman furnace inducer blower motor and blower fan turn on at same time led is blinking 4 flash.

Hi, this is not right for sure. On the panel of the furnace, glued to it or some other area inside, you will have a list of codes and the amount of flashes the led is flashing that will tell you what is taking place. They are all different, so 4 flashes will say something about the inducer motor I am sure.Find the code for 4 flashes and it will tell you what is going on. It may be a fan relay sticking, or a flame roll out switch has tripped causing the fan to come on and run, this happens for safety. Please keep me posted on what you find in the comment box to me, and we can go from there if you haven't already fixed the problem. Make sure you stat is set for the fan to be in the auto setting, I am sure you know this. Please keep me posted on this.Please rate me on my help to you on this, thank you.

My husband and i were just recently given the queen size, dual remote heating blanket from you guys. When we try to turn on either of our remotes, it flashes F2 consistently unless unplugged. Is there...

The first link has some info about the F2 code.Apparently it used to be seen as FF but was changed.It is a power problem.It is still the same problem,which is REALLY not good.The next couple of links are forums which people also have the same problem as you.I would seriously get rid of that blanket.I saw someone mention EMF.I know exactly what EMF is and it is not an issue with this blanket at all,and is present in many things.A microwave probably has more,and still is not an issue.Anything that plugs into a wall has some form of EMF present,so do not even worry about it.

Dyna glo heater

The first thing you need to do is put some kerosene in it, it's a simple step that a lot of people tend to forget. After that make sure it's plugged in and turned on and it should fire right up. Hope this was helpfull poolmistress. You could also have your husband look at it, i hear he is pretty good with stuff like that.
