I just bought a Rinnai 1004 propane heater for my basement. I also bought the 80" extension kit. The exhaust hooks up fine with the extension. My problem is with the fresh air intake. Do they make an elbow for the top of the extension hose for the fresh air intake? Thank you David Sterling

Steve, there are a several of basic things that can cause this problem.
1. Air filter is clogged. Turn electrical part of unit OFF, Remove and Clean Filter, if necessary.
2. Air intake obstruction. Look for air intake obstruction around the front of the heater.
3. If your unit is a flue-less heater, Oxygen Depletion Sensor (ODS) may be partially clogged with dust, link or pet air. Clean Pilot Assembly using canned compressed air with a straw nozzle (like you clean your computer with).
4. Gas pressure fluctuation to the heater. This will require a service call from an authorized Rinnai Service Technician,
Hope this helped you to troubleshoot and solve the problem.
rinnai has a technical bulletin out on this condition #28. It instructs the technician to adjust the gas pressure. You can get a copy of this bulletin by contacting rinnai at 800-621-9419 (US). or at rinnai.us
is this a vented or non vented unit? have you checked the rinnai distributorship? call Adirondack Hardware in Keeseville NY. They have parts for Toyostove, Monitors and Rinnai heaters. Their staff are very well versed in all kero and propane heaters.
The fitting on the back of the unit is 1/2" MPT. Wouldn't suggest messing with it if you are not familiar with propane or natural gas. Make sure the unit is set up for LP if you are going to use a portable supply tank. These units are very reliable. Check all fittings with a diluted soap and water solution before turning on the unit. If it is not connected to it's venting system, you would have a forced induction source of ignition if you had a leak in your piping. These units should only be installed by a licensed plumber or gas fitter, one simple error could allow carbon monoxide (CO) into your house
Do you have the Economy button on? If so, and you have a large space to heat or the outside temp is very cold the unit may not be able to keep up. If this is the case the stove runs forever, trying to reduce the temp by 2 degrees every 30 minutes. This may not work for your space and outside temp.
Your ideas about the intake and exhaust are not quit right. There is a fan that pulls air from outside over the outside of the exhaust pipe (to preheat it). This fan actually pushed the combustion gasses all the way out the exhaust. The exhaust exiting should be a little hot. In very cold temps, frost can build up around the air intake, which is right around the exhaust pipe. If you see this you will need to keep it clean. It is a good idea to look at the exhaust everyday when it really cold.
I had the identical trouble with my Rinnai 431F just now & read the unanswered posts.
I checked my intake & exhaust & found them connected & intact then went out to check the exterior vent assembly. The "bell" or dome was almost entirely clogged with ice.
I suspect the 60 - 76 lights flashing means insufficient combustion air.
Anyway, I took a hair dryer to it & in 10 minutes it was working as well as ever.
This won't help you October posters but if anyone else has this problem in the future I would start with the outside vent assembly. Get a good look right up inside because I would have missed this ice if I didn't get up close with a flashlight.
