Question about Dayton (3E379) Heater

Dayton Fuel Trimmer is lame heater, need to adjust setting

I moved into a 1200 sq ft. work/live loft with the only source of heat being an old Dayton Fuel Trimmer natural gas heater hanging from the ceiling in one corner. This thing barely cuts the cold air. If I want warmth I have to stand in front of the blower vents. Is there any way of adjusting the gas output on this heater. I can see inside through the back where the gas flames are supposed to be heating the metal elements inside. It doesn't look like they get very high or hot. And it seems the auto fan kicks on way before it has time to heat up any elements inside, thus barely warm air. Is this normal?
I think it was install in the late 70's. What can I do to get this thing to run hotter? I'm tired of wearing hat, scarf and sweaters inside my apartment. ~ Bundled up in Oakland

Where is the summer/winter switch located on Dayton Fuel Trimmer furnace model 3E438A.?

The typical 'summer/winter' switch is an added switch associated with OLD heating systems back in the 50's and 60's before central air conditioning became common in homes. I doubt that your new furnace had one installed because you can accomplish the same thing by switching the fan on at the thermostat sub-base. That is, of course, providing you have a subbase with 'fan-on-auto' on it.

My landlord installed this brand new out of the box. Our apt is 900 sq ft tops. This unit can't even cool down our living room and kitchen. If the whole 2 bedroom apt is 900 sq ft, you can imagine how...

The AC your landlord installed is rated at 8000 btu which is way too small for 900 sq ft. You need at least a 15000 Btu Air conditioner and a 'well insulated' house to be cool.
A good rule of thumb in the AC business says you need 1 ton (12000 btu) of Air conditioning for every 600 sq feet (if the house is well insulated) - if not - then you will need 1 ton (12000 btu) for every 400 sq feet.
So, if you have 900 sq feet and the house is well insulated you should have at least a 15000 btu unit.
If it's not well insulated you will need 24,000 btu.

Do you think this unit would work for a large greenhouse on a 250 gal propane [email protected] Thanks

Depends on how large, "large" is? That particular heater has a BTU output of 80,000 to 200,000 BTU's.
That's a lot of heat. I suspect if you have a way to move the heat around some (like ceiling fans on slow speed), it would do an adequate job of keeping plants warm. But, keep in mind, this is not a Vented Heater. So, with that high a BTU output, you would need some makeup air. That way any residual fumes won't damage or kill your plants or you.

This type of heat is a moist heat. That's felt very quickly. So as far as "large" is concerned ... at 80,000 BTU's, "large" needs to be at least 1200 sq ft, with some minimal fresh air input & air movement. Of course, during the day light hours, you could turn the heat down considerably and let the sun heat the green house. That would save on gas consumption too.

Furnace will kick on, begin heat up, go to the point where the fan should start and the whole thing shut down. If I move the thermostat down below the temp it show, it will start again and do the same...


Sounds like the blower motor is bad and then the unit is kicking off on high limit....

Probably nothing you can do with out getting a new motor to replace the bad one...
