Will either be the unitrol control box or the thermocouple, when you push down you are holding two magnets together and waiting for a small charge to be created from the probe in the flame , if this is not working you have no charge and the magnets won;t stick to allow the valve to open, change the thermo and see if that works first, its way cheaper than a new controler

Pilot lite will not stay on when I release the igniter pressure knob REH-18-N wall heater!


IS there gas? YES ok. So if you can get the pilot lit, but when you let up on the button it goes out. Few things to check. On some heaters the manf. install a safety switch to drop the pilot out if its not venting or if its over heating.

This is regarding my Rinnai gas heater Model 1260 S.When On button is pressed, it burns and glows the plate but when released , Gas stopped and it turns off.


problem is proberly the thermocouple burnt out .FSD
(fail safe device) normally you push the button in and the pilot light or flame is ignited,this flame heats the thermocouple that generates a small voltage that holds the gas valve open.
if the thermocouple is burnt out or not set correctly in the flame or the pilot flame is to small , as you say when you release the button it goes out, looks like you need a new thermocouple.

I have a dyna glo 30,000btu lp ventless wall heater. I know it needs the ingniter replaced. I have tried to light it by hand and can not. It seams like their is know gas getting thru,is this possible


yes you have to get the thermo couple hot in order to get the gas valve to open to ignite the main flame
You are probably trying to light the main flame and not the pilot
light
Hold the pilot light button down and put flame to the pilot light opening
You need to be very careful depending on the type of flame you are using to light with the thermocouple could get hot enough to open the main burner flame and it will ignite

I suggest replacing the igniter rather than doing the above step

Need pilot light assembly for Rinnai gas heater model #REH-25-P


Unfortunately, Rinnai only sells repair parts through their authorized dealers. Contact the dealer you purchased it from. If you are not the original owner of the home/heater, you can go to Rinnai's website and search for a dealer near you. http://www.rinnai.us/direct-vent-wall-furnaces/

Have a vent free lp wall mounted heater.40 lp tank with regulater. pilot light will light but only the tip of pilot light is flame.there is a space between pilot light and tube where lp comes out. does not...


Too much gas pressure. Are you sure that this is a LP heater and not a Natural gas heater? Is the regulator you have rated under 1/2 pound pressure? Try to throttle down the shutoff on the tank to see if pilot gets better. If so, you have a pressure issue. Gas you adjust the pilot gas valve?

Pilot light won't ignite on a Rinnai 2000 1


The trick is that it may take a long time for the flammable portion of the gas to reach the pilot light orifice where the flame lives. This happens a lot when the pilot flame has been out for some time. There won't be a clicking sound as YOU are supposed to provide the flame - it's not like a cooking stove with such conveniences, because the pilot light is only an occasional thing to light it's rare to find an ignition source built in. I'd hate to see you spend good money when all you need to apply here is time and a flame.

Check regulator on the unit.
Check pilot unit on the heater
use soapy water to check for leaks if see bubbles turn off main gas supply valve.
always turn off gas supply before any checks or repairs are made
when all else failes call your local gas provider to check heater and gas supply

Heater goes off


Possibly A bad thermocoupler. It is the part that looks like a stiff solid copper wire with on end sticking in the flame of the pilot light and is a safety feature if the pilot goes out it starts to cool and the resistance changes back you the module and the module shuts the gas off. I have seen these go intermediately faulty in waterheaters and do just what you described.
