Re: Gas wall heater

The R70ET is not a wall heater but a bullet style torpedo heater. it runs for a while then shuts down. first check that the photocell is clean. you'll need to unbolt the top cover. when pointing it make sure it "sees" the flame in its holder. if it still shuts down replace the photocell. the site www [dot] desatech [dot] com is the same place I get parts from for heaters.

It could be either the thermostat or thermocouple is not getting correct voltage so will intermittent turn on and off.

SOURCE: heater keeps shutting off !!

I have model 5532, but I think they all have the same problem. There seems to be a safety device in the ceramic heater that turns off if it gets too hot. It "remembers" when this happens as well and will shut off until it is unplugged for 10-15 minutes.

This happens on even lightly used heaters if used in dusty conditions. Dust builds up behind the ceramic heater and the lack of flow causes it to overheat. The unit must be dismantled and the dust brushed/vacuumed out. The good news is that not only will the heater work again, but it will have better airflow too!

To do this, tech support and other people say to "clean the rear grill", but my rear was not dirty. The front grill had some dust that I vacuumed clean, but did not help. In my unit there are no filters before the air goes through the heater element. The problem is in the center of the heater. Taking out the internal fan (four screws on the sides of the squirrel fan box), I could see that the radiator was over half covered in dust. I cleaned that dust out using a shop vac and the problem went away.

Opening the heater was a little tricky, two of the screws were triangle head screws. Once inside, however, it is a simple proceedure to remove the fan. Of course, you should unplug the heater and wait a while before opening it up to make sure there are no electrical charges stored in the unit.

It sounds like the thermocoupler is either not adjusted into the flame properly, or you may have gotten a bad one. The thermocouple is the main thing that makes the pilot work.

You say it shuts down-
Does it have to be reset to get it going again?

Does this heater have a pilot?
if so, when was the Thermo Couple last changed?

Tell us more clues, so we can help you get to the next step.

I have a glow warm 20000 btu natural gas unvented heater. The unit is wall mounted. It won't stay on for more than 15 minutes, then shuts itself off. Its in a corner if that makes a difference... but has...

well, these heaters are typically thermostat-bound, and I have found that they simply will not burn continuously, like a blue-flame heater. Try turning up the setting--this will make it come on/off more often, effectively heating at least one med-lg room, and partially for adjoining areas. Keep in mind that these only rated for 700-1500 SF--that is NOT the floor measurements, but square feet of airspace; eg., a 10' x 15' room has 10' x 15' x 8' (8 foot ceiling) =1200 sf. That said, My 15k btu wall unit had been the sole heating source for my entire home for 5 years, until last year, when I acquired another smaller unit. However, I typically only use a few rooms, and shut off unused areas (ya, was 'cool' in unused back room areas).

If the unit has a wall thermostat, remove one of the wires from the thermostat. If the unit stops it indicates a bad thermostat. If it continues to heat, remove one of the wires coming from the thermostat going to the gas valve inside the heater. If it continues to heat you have a bad gas valve. If the heater shuts off, you have a bad thermostat wire (short).
