Rinnai Convector 404
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.
