Miller Trailer Furnaces
servi...@my-deja.com
How do trailer furnaces work?
This one has a blower motor
attached to the burner. It is older (Approx 1974)It is Natural gas.
How does this work with a pilot? How is it that the pilot does not get
blown out? Wher does it get the air from and how does it blow into the
exchanger in such a way that it does not blow the piolt out?
What is the proper way to service this burner/pilot?
I have searched the internet and have not found any imformation on
trailer furnaces-especially older ones.
"Thank you very much" in advance to all the techs who respond:)

Just like the others , but it heats a trailor.

Pretty good when serviced properly.

The furnace is divided in to burner air and room air that passes
throught it. Air is taked from the floor of the furnace area and passed
into the burner box. The pilot lite is in this side of the two
sections. Most of the 74 models didn't have forced air and air was
drawn in by flame heat leaving the fire chamber. When the gas valve
calls for heat it will open and let gas to the burner jets and the
pilot lite will lite the flame. The flame vent gas will go up and out
upper vent pipe on top of furnace. This completes the burner area and
how the flames are keep seperate.
Now the blower fan that sets on top is activated by thermostat that
will turn on blower when the fire chamber get to about 130 degrees and
then cut off when it gets back down to 110 degrees. The Blower air is
totally seperate from the burner fire chamber air. The blower turns on
and pull air from the sides of the blower assembley in to the outer
edge of fire chamber and passes alone the wall of the fire chamber. The
heat is picked up and then on out into duct system under the trailor
and on to each room to warm the trailor. The blower air never inters
the pilot lite area at all. It just passes around it and picks up the
heat.
> What is the proper way to service this burner/pilot?
The best Is to have it serviced by a furnace tech one time to check for
any known problems that maybe wrong with it.
Now with the above in mine. Open the metal door upward and lite the
pilot lite by the litting instruction wrote on furnace wall , but have
thermostat in off possion when doing so. If there is any odd things
that happen in this process . Stop and have the tech to go through the
litting proceedure with you. Do close and lock door before tring to
run.

Now after all this said i would get a Tech out to Service the furnace
and check for problem . Then Pick his brain on litting proceedure and
inspecting the furnace. If this furnace is new to you , you need to
have it checked out properly one time in it's life to see if there is
any dangerious problem that maybe wrong with it. Then in the future you
service and lite and run it.

That is a nasty furnace to work on... Highly suggest you either hire a
Good service company or the brother-in-law that cheats at cards.
The Pilot has a draft hood on it.... The vent is a concentric....Flue
gases
go out the center pipe and combustion air comes in the outer pipe.
Whole burner assy comes out... sometimes.... sometimes not....
Kinda like a rubics cube... You have to rotate, twist, etc until the
right combination is hit.. Again I stress... Hire a pro for that unit.
Trailers burn fast and dead is for a really long time.
Most trailer furnaces are either Coleman or Intertherm.

Same with the oil furnaces, but Millers are more prominant around these parts
(and the most reliable).
Don Ocean
I can't keep up with all the buy-outs, but Nordyne is/was the maker/owner of
Miller and Intertherm. I haven't seen a recent Miller... But Miller and
Intertherm
for trailers were the same... Are they now different?
HVACMAN

A Classic!!!
Definitely should be in the FAQ or Newtie's book!

Miller is now Frigidaire which is owned by Nordyne which has sister
companys Intertherm and Delta therm. Then Colman/Evcon is sister to
Intertherm Which is owned by YORK . So everything is a York now.
A lot of changes but what you said before is true , everybody is the
same company and everything is a York now.

I had never heard of them before. Checked out the plate, and sure 'nuff...made
by Nordyne.
And Don: I haven't seen a Miller come through the door in a while. Almost all
the "trailer" furnaces we get are Intertherm or Coleman. Turtle has been
keepin' up with the go-ins ons with these peoples!!!!

Your answer below is very obvious statment but not the answer to the
question.
Again- This unit has a COMBUSTION blower. We are not talking about the
fan blower. Is the pilot enclosed by a shield to protect it fom being
blown out by the combustion blower?

No these units have a manual sparker to like it and you cannot access
the pilot from a little metal door.

Hey HardCrab the Frigidaire condenser is warrentied for 8 years all
parts and if compressor burns up in less that 5 years you get a new
condenser unit to install on the job. [ Frigidaire / Miller ]
MechAcc
and Miller brands under the manufactured home furnaces.

Sounds like it may be a Miller MGC-80 or MGC-100 Power Gas
Burner. They used the same heat exchanger and cabinent as the MOC model
oil furnace. If I recall correctly, you could swap burner assemblies to
change from gas to oil. Some even referred to these gas furnaces as "gas
guns." The air was drawn from beneath the floor through an air
chute. The exhaust flue was a single pipe, unlike the concentric design
of mobile home furnaces now. I suppose the design of the draft tube kept
the pilot from blowing out while the burner motor was running; I never had
that happen before. Just service it like any other pilot burner. The
main problem I find is that on old mobile home gas furnaces, rusted
retainers, screws and brackets make replacing orifices, t-couples and the
like somewhat challenging.
Miller at that time was manufactured by Lear Siegler
of Holland, MI. The Miller AC and heating division was sold to Intertherm
which was bought out by Nordyne. Replacement parts may be a problem.
On a furnace that old, be sure to thoroughly inspect the roof jack,
flue and heat exchanger. Mobile Home furnaces are notoriously bad about
rusting out if the cap on the roof jack is rusted out or missing (very
common). Rain water pours inside the furnace and it's not long before
it's a duster. I would look at it as an opportunity to sell your customer
a new furnace if major work is required.

ps If you start to become involved with trailer houses, you must update
your vacabulary.
trailer house = manufactured home

You sound like you have a lot of trailer..oops..Manufacture home
furnace experience ha ha :)
Best answer to my origional post.
Since I first sent the post I was able to find more imfo on this unit
and your answers sounds pretty good.
Thanks again
