Use the template to position the hole to be drilled.
The "red dot" indicates the exact center of the hole.
Using an electric drill and a long drill bit, make a
pilot hole through the wall (Figure 7). Be sure the hole
extends through the outside wall.
Step 4: Drill a Pilot Hole
NOTE: The following directions apply to "standard"
installation. For other methods, follow instructions
included with accessory kits.
For walls up to 8% inches thick, use a short
flue pipe; for walls up to 14% inches thick, use
a medium flue pipe; and for walls up to 20 inches
thick, use a long flue pipe.
Position of hole
Template
Fig. 7
CAUTION: The opening on the inside wall should be approximately % inch higher than on the outside wall so
the flue pipe will slope downward when installed. This will allow condensation to drain outdoors.
Step 5: Cut the Hole for the Flue Pipe
Using a hole saw attachment and an electric drill, cut
a 2]4 inch diameter hole through the inner and outer
walls (Figure 8).
NOTE .-After cutting the inside wall, remove the insulation.
Make sure there are no obstructions inside the
wall, such as electrical wiring, water pipes, hot
air ducts, etc.

Step 8: Replace the front panel and the louver.
Step 9: Connect the fuel line from External Tank as follows.
NOTE: External tank installations must comply with the
National Fire Protection Association code NFPA
31 or locally applicable codes, such as the 1979
Uniform Mechanical Code No.5-1. that are
consistent with NFPA 31. Check with your local
building official.
To install a large capacity, gravity fed external tank,
follow the instructions below, and refer to Figure 27
for one possible installation. Use of a qualified installer
is recommended.
• Installation height of the bottom of the fuel tank
should be 16 inches or more above the floor surface
on which the heater stands. This ensures that inlet
fuel pressure will be sufficient.
• The top of the fuel tank should be no higher than
Q1A feet above the floor under the heater. Heights
above Q1A feet will exceed the 2.5 psi inlet limit, and
a pressure reducer will need to be installed at or near
the unit.
• The horizontal length of piping should not exceed
100 feet and should be free of sharp bends or
obstructions.
• Piping should include no inverse U-type bends (to
avoid air locks, which could block the fuel supply).
• Only %inch OD copper tubing should be used.
The tubing should be bent carefully to avoid crimping.
• A fuel filter is recommended for use on the fuel line
near the tank, and a shut-off valve should be installed
at the tank.
• Flare connections should be used at the fusible link
valve connection on the heater and at the fuel filter
to be installed at the tank.
• The fuel tank should be located no closer than 3
feet to a source of heat.
• The fuel tank should have an opening for filling on
the top and a vent with a weather-proof cap on the
side. On some tanks the vent and fill spout use the
same opening.
When using a gravity fed tank to supply fuel, the inlet
pressure to the heater must not exceed 2.5 psi.

12 degrees instead of the normal 4 degrees.
The advantages of this feature are to increase the overall efficiency of the unit by:
1. Decreasing electrical consumption by decreasing the frequency of ignition cycles.
2. Reducing heat loss during the prepurge and postpurge cycles.
3. Reducing inefficient combustion associated with start up and shut down.
4. Prolonging component life by decreasing expansion and contraction of internal parts.
NOTE: This feature could be compared to driving an automobile in stop and go traffic (regular mode) versus
highway driving with cruise control engaged (Economy Plus mode).

more than 5 minutes.
SECTION K
PROTECTIVE FEATURES
OVERHEAT PREVENTION
LOSS OF POWER-AUTOMATIC RESET:
If your heater overheats, a thermostatic switch will
automatically stop the flow of kerosene and extinguish
the flame. The Burner status indicators are blinking.
Restore heater operation by following the steps
below.
NOTE: Other symptoms listed in the trouble shooting
chart may cause burner status indicators to
blink, besides an overheat situation.
NOTE:If power to the heater is interrupted, a thud-like
noise may be heard in the combustion chamber.
This is nomal, and should not cause alarm.
For power interruptions of up to 5 minutes, the
set memory is kept and will resume operation
automatically with the set memory.
For power interruptions beyond 5 minutes, your
heater will resume operation (after a 3 minutes
cool down period) in the MANUAL mode and
maintain room temperature according to the
setting temperature you've selected by using the
slide selector for the reset temperature at the
lower right hand side of the cabinet (Figure 31).
When the TIME Button is pressed or the TIMER
SELECTOR Button is pressed to illuminate the
CLOCK SET Light, The Display Window will
show 88:88 indicating the need to reset the
clock and re-program the heater for automatic
operation.
REMARK:In order to display reset temperature,
it should be set before the heater is plugged
in and energized.
New reset temperature selected after plugged
in will take effect only after a power loss, greater
than five minutes.
Step 1: Turn the Heater Off
Press the Operation Button to put it in the "Off" position.
Step 2: Allow the Heater to Cool
Wait approximately 30 to 45 minutes for the heater to
cool completely.

The overheated condition may be caused by obstructions
blocking the air flow to the heater. Check:
• The front of the heater
• The circulation fan (on the back of the heater).
• The flue pipe (outside)
Step 5: Remove the Louver
Remove the screws at the louver, and carefully remove
the louver (Figure 32).

SECTION L
CARE OF THE HEATER
Push operation switch to "OFF" remove the AC Plug from the wall outlet and wait approximately 30 minutes for
the heater to cool before performing any of the following steps.
Step 1: Retrieving Objects from Inside the Heater
Should an object fall inside the heater, through the
grill openings, it must be removed to avoid affecting
the operation of the heater.
After allowing the heater to cool, remove the front
cover panel. (See Step 5 of the previous section.)
After the object has been removed, replace the front
cover before attempting to re-start the heater.
Step 2: Cleaning the Cabinet
When the cabinet is soiled, wipe it with a damp cloth.
Restore the shine with a dry cloth.
The use of abrasive household cleaners may dull
the finish.
Step 3: Checking the Flue Pipe
At the beginning of each heating season, check the
inside of the flue pipe. Foreign matter, spider webs,
etc. must be removed.
Be sure all fittings and joints are tight.
Step 4: Cleaning the Interior
Remove the Front Cover Panel (as described in Step
5 of the previous section), and vacuum and wipe away
dust or other accumulation.
Look for signs of fuel leakage around the joint pipe
and the bottom of the cabinet. If fuel is detected, wipe
it away and if necessary, contact your MPI dealer for
any necessary repairs.
Step 5: Cleaning the Blower Guard
Heating efficiency will be reduced if the blower guard
at rear of the cabinet is blocked with dirt or dust.
Blockage also produces a rise in heat that could cause
the heater to shut off.
Wipe the guard clean at least once a week.
25
Step 6: Cleaning the Fuel Strainer
The strainer of the fuel constant level valve should be
cleaned once a year and before storing heater at the
end of each season.
Step 6-A: Valve Position-Open/Close
Turn knob of the shut -off valve installed at the fuel inlet
connection to close the fuel line. (See Figure 27).
NOTE: The valve 'is located at the back of the heater.
Turn counter clockwise to open, clockwise to
close. If threaded valve stem is sticking up
about yc, valve is open. If handle screws off
stem, valve is closed.
Step 6-B:
To catch the fuel which will drain out, set the drain
guide made by cardboard below the strainer cover,
with a small container under it. (See Figure 33)
Step 6-C:
Loosen the two screws from the strainer cover and
remove.
Step 6-D:
Remove the strainer and wash with pure kerosene.
If strainer is damaged, replace it.
Step 6-E:
Return the strainer to its original position.
strainer cover and screw to secure.
Replace
Step 6-F:
Wipe away any spilled kerosene.
Step 6-G:
Turn the knob of the shut-off valve to open. Check for
kerosene leakage.
NOTE: Your Monitor may sometimes require more
service than that shown above. Should this occur
please contact your Monitor Products, Inc., dealer
for service. A preseason maintenance check up
could be performed by your dealer to ensure
trouble free operation during the season. Ask
him for details of his routine maintenance
program.
