REDDY HEATER PRO 70
I have a Reddy Heater R100 that ran just fine until one day it
wouldn't ignite. I took the cover off to see if it was sparking and it
ran just fine with the cover off. I got on the Internet to see if there
was a definitive answer as to why it would only run with the cover off;
there wasn't. So I decided to troubleshoot it step by step instead of
replacing everything at once. You can thank me later.
Step 1: Dumped out old fuel, made sure the tank was completely dry and
clean. Put in fresh kerosene. This is an absolutely hideous job.
Result: Still would only burn with the cover off. Said bad words.
Step 2: Replaced all three filters. Result: Still would only burn with
the cover off. Didn't say bad words, just thought them.
Step 3: Removed the end filter cover and pushed on the pressure relief
ball. It seemed to be stuck.
so I marked the relief screw, counted the exact number of turns to take
it out, and washed the end filter cover and small parts with Dawn
dishwashing detergent. Harsh solvents can melt the plastic on the end
filter cover. Blew everthing dry. Put a little oil on the spring and
ball so they wouldn't rust. Put the relief screw, spring and ball
together, making sure I turned the screw back in the same number of
turns that I took it out with, within a tolerance of about 1/8 turn.
Result: Still would only burn with the cover off.
Step 3: Downloaded a manual from:
find out the spark plug gap. They didn't have one for an R100 so I used
the one for a R100EDI. I cleaned and set the spark plug gap to .055".
I think later heaters use .075" or .085". Check your manual. Result:
Still would only burn with the cover off.
Step 4: Removed the nozzle. Put a clean paper towel under the input and
sprayed carburetor cleaner into the output end of the nozzle,
backflushing it. Four or five pieces of crud came out, onto the paper
towel. Really cleaned the nozzle good. Blew it off with compressed air
to make sure all of the carburetor cleaner was evaporated. Replaced the
nozzle. Result: O frabjous day! It worked just fine for about a half
hour, then it started coughing and smoking.
Step 5: Removed the nozzle again. Put a clean paper towel under the
input and sprayed carburetor cleaner into the output end of the nozzle,
backflushing it again. Four or five pieces of crud came out, onto the
paper towel, again. Really cleaned the nozzle good, again. Cleaned the
fuel filter and the upper fuel line. Made sure everything evaporated
before I put it back together. Result: works great with the cover on.
Ran the tank of fresh fuel empty. Put the original fuel back in, it
So, if in the future, I have the problem where it doesn't burn with the
cover on, I'm going to start with the nozzle, upper fuel line and fuel
