MAXI-HEAT®SETUP PROCEDURE
TheFrostFighterheaterunitsneedtobesetupforeachoperationandtunedtooperateefciently
depending on the altitude of intended use. As you go up in elevation, the air gets thinner. As the air
gets thinner the ability to burn or consume a certain amount of fuel is diminished. When you move the
machine to a different elevation you may need to change the nozzle size and air settings to get a clean
efcientburn.Thenozzlesizeisdeterminedbythenumberofgallonsperhournumber(GPH).Anumber
is stamped on the nozzle indicating the amount of fuel that the nozzle will deliver to the burning chamber.
For higher elevations, selecting a nozzle that delivers less fuel allows you to make the air mixture adjust-
mentsneededtoburnallofthefuelwithlessair(thinnerair).
Test Equipment:
Bacharach Oil Burner Smoke Tester – is used to determine the amount of soot in the exhaust gasses.
This can indicate the level of combustion being achieved. It is recommended that the Smoke Tester be
used for tuning the Maxi Heat Frost Fighters.
Instructions for setting up the Maxi Heat at elevations above sea level.
1. Installfuelpressuregages(ifnotequipped).
2. Set Fuel Pressure to 140 PSI
3. Head Setting at #6.
4. Shutter Setting – Full open. #5Setting.
· Fine adjustment – very little change in air mixture results when changing the settings from 1 to
10.
5. Band Setting - ½ open. — #5 Setting
· Starting at 50% open allows adjustment in both directions during tuning.
6. Installnozzlesizethatgivesamediumtogoodburn(2or3)onTrue-SpotSmokeTester
· While the fuel pressure is maintained at 140 PSI, Head Setting at #6, and Shutter and Band Set-
tings are at the #10 and #5 settings, test nozzles until you have a nozzle that gives satisfactory
initial smoke tester readings.
· Example:
1. Initialstartupwithsettingsasnotedabove(Fuel140PSI,Shutter#10,Band#5)givesa
smokereadingbetween6&9(heavysmokeonteststripwithvisiblesmokecomingfromthe
stack and possibly a rumbling sound coming from the burner.
2. Smokeindicatestoomuchfuelornotenoughair.(fuelnotbeingtotallyburned)
Action:
1. Turn off switch and let the Frost Fighter cool down.
2. Shut off the power to the Frost Fighter.
3. RemoveFuelRail,anddeterminethenozzleratinginGPH(gallonsperhour)e.g.3.
4. Selectanozzlethathasanoutputlowerthan3.(Readthefollowingsuggestionsforselectinga
nozzle size and depending on the initial startup and smoke test readings you can make an informed
decision on which nozzle to select.
· For heavy smoke and a rumbling sound you may select a 2.5 GPH nozzle for the next test.
· For heavy smoke and no rumbling, you may want to select a 2.75 GPH nozzle for the next test.
5. Install nozzle,

Fine Tuning the Frost Fighter Burners
1. Use the True-Spot Smoke Tester to determine where you are on the Smoke Scale.
2. To reduce the amount of smoke, open the band 1 or 2 numbers and recheck with the True-Spot
Smoke Tester.
3. Make further adjustments if necessary to achieve the lowest number you can on the Smoke Scale.
4. Tighten the air band and shutter-securing screws to prevent them from moving after you have made
the adjustments.

FUEL AND LUBRICATING OIL
The temperatures mentioned in the table are
the ambient temperatures at the time the engine is
started. However, if the running ambient tempera-
tures are much higher than the starting tempera-
tures, a compromise must be struck and a higher
viscosityoilused(providedstartingissatisfactory).
Multigrade oils overcome the problem provided
theyhaveasuitablespecication.
NOTE: In testing this engine at the factory, the
manufacturer uses on oil for moderate and low tem-
peratures. This oil is specially formulated to assist
in the break in period, and the manufacturer would
like this oil to be left in the engine for the rst 50
hours. Additional information on fuel and lubrication
specications can be found in the Engine Instruction
Manual.
