Rheem Power Vent Water Heater Service Manual

Refer to this manual. Installation and service must be performed by a qualified installer, service agency or the gas supplier. Failure to properly vent the water heater to the outdoors. Tion air for a power vent unit will be obtained from the surrounding area. Failure to install the blower assembly and properly vent the water heater to the outdoors as outlined in the Venting Section of the Installation Instructions in this manual can result in unsafe operation of the water heater.

Help.My water heater is intermittently failing - and I can't diagnose the problem When I realize the thing isn't working, the power vent fan is running without the burner on. I cycle the power off and then back on to initiate the 3 tries to ignite the burner here are the things I have witnessed when I turn the power off and back on: 1. Rambo 3 full movie free download mp4 download. A few clicking noises. My guess is that one is coming from the controller (not as loud), calling for the gas valve to open. Then, multiple louder clicks, and no ignition. Only the softer click (again, I'm guessing coming from the controller), followed by nothing form the gas valve, and no ignition 3. The softer click, followed by a louder click, the burner ignitess for a small period of time, and then goes out (between 2 and 40 sec), to the sound of another click 4.

Successful ignition that stays lit until the water is hot. The odd thing that I notice is that when I disconnect the leads to the pressure switch, scrape them a bit with a screwdriver, and reconnect them, I have a higher rate of successfully getting the heater to light. I replaced the pressure switch (~$25 - it was worth a shot), that may have improved things a bit for a while, but now it's going downhill again. The new switch came with 2 new leads - I replaced the one between the controller and the switch, but the other one that runs into a box with a cover is hard wired to a little plastic enclosure, so it doesn't seem replaceable. The heater is about 13yrs old, so I don't want to put much into it before considering replacement (I assume the expected life is less than 20 yrs), but if there is an easy, cheap fix, I'd love to try it. Thanks in advance. [align=center] STANDING PILOT IGNITION[/align] The thermocouple is the pilot's, well, co-pilot!

It is the electronic device that senses if the pilot flame is hot enough to sustain burning the gas fuel from the burner. If the thermocouple thinks it's safe, then it keeps open the main gas valve located in the pilot assembly. If the thermocouple does not sense enough heat from the pilot flame (such as when the pilot is out), then the thermocouple shuts off the gas valve to the burners.

How the Thermocouple Works So what is this thing and how does it work? Well the thermocouple (technically called a thermocouple junction) is a device that contains two metal wires welded at the ends and placed inside a protective metal case. The thermocouple sensor is found at the business end of the pilot flame and is designed to be placed in the hottest part of the flame. The other end is connected to the pilot valve body. As the thermocouple heats up, it produces a small amount of electricity and when it gets hot enough from the pilot, send a signal to open the gas valve by using a solenoid operated by a 24 volt transformer. The thermocouple calls the shots, and by converting heat to an electrical signal, it allows the gas valve to open or close. Once the gas valve is open, gas is then constantly supplied to the pilot and as required for the gas burners (as called for by the thermostat).
