Hi I just inhereted a Renni 516TR LPG space heater. Would you send me the handbook before I get to use it, so I start it correctly and use it to its best operation. Regards Andrew

Hello Robert,

I do not think you need a handbook for that.
Most cooker tops have nozzles that you can replace. They look like the ones in the link.
there are numbers printed on these nozzles.
LPG nozzles have smaller holes in it.
Just find out what size you need, they mostly are wrench 7 mm
Kind regards, Dik

the pull on the bottle makes it freeze the lpg has to bubble to make gas if the line off the bottel is too small and the heater draw is large the the bottle will freeze, so bigger tank and bigger draw off line .

There is a makes plate on it which say NG for nat gas or lp for lpg

Try national energy they sell convestion kits It would need a gas fitter to do the work , you may need to a quote on this , they would be able to tell you if it is worth it ,its hard to tell with out looking at the heater .

I am assuming this is a tankless heater. Are you turning the water on full throttle and is there full flow. First thing to check is the small filter screen on the inlet of the water heater. If the flow is reduced the water heat will not fire.

hi change the burner injector and the pilot and the reg or the spring inside , you should be able to buy a kit for this.

i have the same heater that had the same problem - today i found out you can't just pull the plug and stick a new one in, the gap has tp be 1/8" - I did just that and it worked and then shut itself down - finally found the book and saw the correct gap = it fired right up

I have had this problem due to the heater 's combustion sensor concluding that all was not well. In my case, the heater had burned up too much of the available oxygen. I didn't notice the lack myself, so it must be very sensitive. I had shut the place up to keep the heat in and eventually it dawned on me to open a door for a minute or so every half hour or so to replenish the oxygen supply.

The situation is worst when the place is very cold as the heater will roar away trying to heat it up as quickly as possible. After I came back for a holiday in winter, I had to set the temperature down to "L" and "Economy" on plus run an electric fan heater for a day to warm the structure to the point where the gas heater could relax and not burn oxygen faster than it could heat the space.

Check convection fan motor.
Get a gasfitter to do it.

Hi This is happening to us and I called Rinnai... they suggested that if anyone either in our apartment or an ajoining one has painted walls or varnished a floor that the convection heater picks up the smell and the only way to get rid of it is to burn it off by running the heater for several hours in a well ventalated room...

I am going to try it tomorrow.

will let you know
