The spark plugs are always on when the heater is on. On the back of the heater, you should see a bolt with a hole drilled in it. This bolt has a spring with a ball under it that acts as a "main jet" in that the more in you screw it, the less the amount of fuel that is fed in. (All the screw does is adjusts the amount of air going to the atomizer nozzle-more air=more fuel/Less air = less fuel.) On my old heater I kept a 7/16" wrench to "fine tune" it because as it and the air in the shop warmed, it would run too rich (no more than 1/2 turn)

How to ajust dayton 155000 btu torpedo heater when running smell like kerosen

You say: When running it smells like Kerosene--
That is what you are burning in it, right?

Is it smoking--- like there is a poor combustion mixture?
-- like maybe not enough air pressure?

There is a pressure adjustment for both-- Please check the manual for adjusting the pressures for your particular model.

Is the front of the fuel powered heater supposed to glow red?

Hi, and the answer is yes. All fuel powered type heaters will glow red, or bright orange. Example, a space heater that runs on #2 fuel oil, natural gas, gas, kerosene, ect. will glow this way, so do not be alarmed. This is normal.

Have older 3e198 kerosene portable heater,will not run but a feww minutes. if i take the top shieldoff it runs great

Set the pump pressure to specs. If unsure hoe to do this instructions are at 's website.

If the heater still has the same symptoms- then change the nozzle. Desa (the mfgr of your Dayton heater) recommends ANNUAL replacement of the nozzle. The nozzle should create a fuel FOG but it becomes a fuel SPRAY after a period of running, due to wear.

Kerosene Portable Forced Air heater comes on, runs awhile

Here is a link to your owner's manual... Look on page 8 and 10. It could be several things. It could only be a dirty fuel filter or the pump pressure may just need adjustment. If you need a part you can contact Master Parts at 800-466-1446 or you can find them on-line at I hope this helps!
