When it’s colder
than a well-digger’s
nose, it’s
not
the
time to find out that
your H120 or H120-1
space heater is on
the fritz.
These space heaters,
have a reputation for
coming out of long-term
storage with problems.
Here are
10
things
you
need to be on
top of when
you bring a
heater out
of storage.
1.
Take a good look at all tubes and
fittings.
Look for stripped threads or
poor alignment. Make the fuel lines a
special priority. Fuel leaks are more
than just a maintenance problem!
2.
Put an eye on the fuel supply and
return lines. Sometimes the storage
goblins reverse them. Use your TM
to make sure the lines are right.
5.
If the heater “flames
out”—the burner stops
or the heater shuts off
during your initial
runup—check the spark
gap, clean the fuel filter,
and clean the fuel
nozzle. Something is
probably dirty.
6.
If the problem is no fuel
pressure, eye the fuel cou-
pling for installation of
pins. Make sure all is well
with the fuel pump, too.
Especially, look for loose
or stripped fittings on the
suction side of the pump
and make sure you don’t
have a broken fuel coupler.
3.
Put the fuel valve
setting in the right
place. Chances are,
you’ll be drawing
from the internal fuel
tank so a switch set in
the external mode
will have the heater
sucking only air.
4.
Look for broken CB2
circuit breakers. Those
storage goblins love to
break switches.
7.
If the LED indicator does not
come on or the heater does not
cycle right, could be you have a
bad remote thermostat.
8.
If the heater fan rattles or
doesn’t rotate, chances are good
you have a loose blower fan.
…make sure
the ignition
transformer does.
10.
Finally, if it is really cold,
watch out for fuel line freeze-up
and keep water out of the fuel
and the fuel filter.
9.
If the burner
doesn’t work,…
Your best
friend is not
your momma
when it’s 20
below
-it’s
your
heater!
Make sure your
best friend is
capable of
doing its job.
H120, H120-1 Space Heaters…
