Keep Air Flowing
To prevent overfiring,
you also need to make sure
the heater has enough air.
The best way to do that is
to use
all
the pipe sections
when you put together the
heater’s exhaust stack.
You see, overfiring isn’t
just a problem of the
heater getting too much
fuel. It’s also a matter of
getting too little air. Fuel
can’t burn completely
without adequate air. By
using all the pipe sections,
you create more suction in
the stack, which draws
surrounding air into the
heater’s burner shell.
Unlike the arctic heater or the H-45
heater, the small heater doesn’t have a
fuel selector control or a fuel flow
adjustment knob. But it does have a sin-
gle burner rate control that regulates the
amount of fuel flowing to the burner. If
your heater overfires, turn the burner
rate control counterclockwise. That will
lower the height of the float bowl and
reduce the fuel flow until the flame is
light yellow or white and the heater
stops smoking and pulsing.
Like the arctic or H-45 heater, the small heater also needs plenty of air to keep
from overfiring. So use
all
the pipe sections when you put together the heater’s stack.
Use all
the pipe
sections…
…to draw more air
into burner shell
Use all pipe sections so
that heater gets more air
Carabiner NSNs
If your unit does rock climbing or rappelling, you use carabiners.
You’ll find a variety of them listed in the FED LOG—that is, if you
know where to look. Three separate searches will net all the
carabiner NSNs you’ll need. Search by item name using the fol-
lowing terms:
• carabiner
• snap link, mountain piton
• snap link, rappeller
Remember to read the characteristics data before you order.
That way you’ll make sure the item meets your requirements.
you’re not
out of the
woods if you
use the small
space heater!

BRIEF
LY NOTED…
Flashlight Focus
If your two-cell, fixed-focus flashlight is too puny for mainte-
nance in the dark corners, order a foot-long, water-resistant,
adjustable-beam, three-cell, krypton-bulb flashlight with NSN
6230-01-247-7549. Use NSN 6240-01-441-8368 to get a replace-
ment bulb.
Threaded Ends
for Water Hoses
The Army doesn’t stock replacement threaded ends for water
hoses. But you can order them at the GSA Advantage website at
Just do a search on “garden hose parts” for a run-down of
what’s available. The threaded ends are described as brass hose
repair couplers and mender. You’ll find male and female couplers
in 1/2-in, 5/8-in and 3/4-in sizes.
