Long Term Report
June 1, 2008
During the past two months the Brunton Vapor AF stove was used on
four camping/backpacking trips in the following locations:
Joshua Tree National Park, California: The low temperature was 51 F
(11 C) with highs around 72 F (22 C). The stove was used in the
National Park Campground during a group rock climbing trip. The
elevation was approximately 4,200 ft (1,280 m). This was a two day
San Jacinto State Park, California: Camp was set up at Lower
Chinquapin located at 9,000 ft (2,743 m). The low was 38 F (3 C) and
the high was 54 F (12 C). There were some wind gusts recorded at the
weather station of 25 mph (40 km/h). There was still an abundance of
snow in the area, trail finding was difficult.
San Jacinto State Park, California: This was a two day solo trip.
Camp was set up in at approximately 9,200 ft (2,804 m). The high
temperature for both days was around 58 F (14 C) and the low was
recorded at 39 F (4 C).
San Jacinto State Park, California: I visited this park on a two day
solo trip. Camp was set up in at approximately 9,200 ft (2,804 m) in
the same location as my prior visit. The high temperature was from
40 F (4 C) to 47 F (8 C) and the low was 24 F (-4 C).
Performance in the Field
Well I must say that over the course of the four-month testing
period of the stove I am very pleased with its performance.
During the past four-months of testing the stove I found that is is
pretty much idiot proof. I was unable to burn liquid gas on the "G"
control valve stem setting and I was also unable to burn canister
fuel on the "L" setting. I will admit there were a few occasions
that I forgot to check the setting of the stove before trying to
ignite it. If it is on the setting not for the fuel I was using it
just does not work. Which I believe is a good thing.
I am still finding that after the stove is in storage or after
transporting it while backpacking the flame spreader cup does not
stay in place. It becomes dislodged and I have to remember to clip
it back into place. While it is not dislodged every time I go to
ignite the stove, it is more often than I think is necessary.
I have used various types of cooksets with the Brunton Vapor AF
Stove during the testing period. On my solo trips I have used my
Snow Peak Cookset that has a base diameter of about 3.5 in (9 cm).
On trips with more than one person I used a Titanium Evernew Cookset
that has a base diameter of just over 6 in (15 cm). The base of the
larger pot is more sturdy on the pot supports. However, the pot
supports are so large and have the gripping teeth on them that the
smaller cookset was stable as well. I did not cook with the flame
turned on high with the small cookset because the flame was being
dispersed to the outside and up the sides of the cookset.
I have varied my fuel use with this stove between white gas and
butane/propane mixed fuel canisters. The fuel canisters used were
the 110 g (3.88 oz) and the 220 g (7.76 oz) size. There was no
difference noticed in the performance of the stove by using
different sized fuel canisters.
When using the stove with liquid fuels I found that priming the
stove can take longer in certain weather conditions and elevation.
It seemed that in colder weather the stove took longer to prime. I
also found that as there became less fuel in the bottle I had to
pump it more for priming.
This stove does not have a shaker jet so the stove needs to be
cleaned manually. After using the stove for four months I decided to
clean it. There were no performance issues and no trouble with gunk
in the fuel line that I could tell. I just cleaned the stove since I
was testing it and I wanted to report on cleaning the stove. In a
nutshell, it is very simple to clean it. The flame spreader needs to
be removed and then just stick the jet hole with the cleaning needle
in the maintenance kit. The needle housing is long and I found it
easy to poke into the jet hole. If the needle does not clean the jet
the manufacturer notes in the directions that the stove can be
cleaned by unscrewing the jet with the multipurpose wrench.
The foil windscreen provided with the stove is constructed of a
heavy aluminum. It is not flimsy at all. Some effort and work is
required to shape it into a circle to surround the stove. I found
that the windscreen is heavy enough that small wind gusts do not
blow the windscreen over.
Over time it seems that the pot support legs sometimes take a little
effort to collapse. I noticed this after my last trip with the
stove. This was the only time I noticed that the one pot support was
stuck a little bit and would not collapse easily.
All in all I found this to be a great stove for backpacking
especially for a group of people. It may be overkill on solo trips
just because of the weight of the stove. However, I think it is
ideal for me to take on winter solo trips when using a canister
stove is not feasible. I like the versatility of being able to burn
either liquid or gas fuels. The stove does an excellent job of
simmering foods without a spurting flame. I still wish there was
some kind of an igniter on the stove that a match did not need to be
used every time. I am pretty happy with this stove and I plan on
taking it on trips that I need liquid fuel or when I need to cook
for a group.
Things That Rock:
Versatility to use several types of fuel including canisters
Not very heavy for a beefy stove
Boils water quickly
Things That Are So So:
The flame spreader cup slides out of place when stored
There is no igniter
This concludes my long term report. Thank you Brunton and
backpackgeartest.org for providing me with the opportunity to test
the Vapor AF all-fuel stove.
