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. Wall Fig. 8 After the hole is cut, use a straight edge and a level to be sure the inside opening is approximately % inch higher than the outside opening. 11 with the 3 #8x%tapping screws(Figure 9).

Fasten the flue pipe NOTE: Top center port is an extra exhaust port. tapping screw Fig. 9 Step 7: Install the Outer Flange Apply caulking material to the inside ridge of the rubber packing (Figure 10). Holding the "Up" mark to the top, slide the rubber packing onto the sleeve (caulk side to the wall). NOTE: If it is difficult to slide the packing onto the sleeve, apply soapy water to the inside of the packing. Once the rubber packing is in place, slide the outer flange onto the sleeve with the conical side pointing outward (Figure 11). Screw the flue pipe nut onto the flue pipe grooves, and tighten it firmly (Figure 11). Rubber Packing Fig. 10 Flue Pipe Nut. Outer Flange Fig. 11 12 Step 8: Install the Spill Tray Place the spill tray on the floor where you plan to locate your heater. Remove the 2 sets of screws from the cabinet (Figure 12). Position the heater on the spill tray so the legs of the cabinet fit into the circular indentations in the spil! tray (Figure 12). Step 11: Connect the Heater to the Flue Pipe Move the heater toward the wall, guiding the joint pipe into the center port of the flue pipe (Figure 14). Be sure the joint pipe is completely inserted into the flue pipe. Screws Retainers Legs Spill Tray Fig. 12 Step 9: Level the cabinet In order for heater to operate properly. It must be positioned on a level surface. Ensure proper leveling by adjusting each leg and by using a carpenters level to check both side to side, and front to back level condition. Attach and tighten both sets of retainers and screws. Step 10: Install the Joint Pipe At the rear of the heater, slide the large end opening of the joint pipe into the exhaust port outlet of the heater. Be sure the joint pipe is fully seated. Slide the fabric cover over the joint pipe (Figure 13). The o-rings that seal the joint pipe may be dry and tight. A little soapy water will ease installation. Step 12: Install the Air Damper If installation is standard (that is no extension kits are required), place the air damper marked with a "STANDARD" over the air intake flange on the flue pipe (Figure 15). Place the hose band around the end of the air supply hose. Push the air supply hose onto the air intake flange and secure the hose with the hose band. Fabric Cover Air Supply Hose Fig. 15 Joint Pipe Fig. 13 13 /VOTE'Do not place intake hose onto metal capped exhaust port. NOTE: The "STANDARD" damper is to be used with extension kits up to a total overall length of 20 inches and a maximum of 3 bends (90° elbow). Air damper is not used when extension kit or kits exceed 20 inches. Step 15: Recheck the Heater Before proceeding, check again to be sure there are no flammable materials close to the heater. Check to be sure the heater is level. Examine the flue pipe to be sure connections are tight. Step 13: Install the Flue Pipe Holder Place the ring of the flue pipe holder around the flue pipe. The other side of the holder hooks in a slot directly above the joint pipe at the rear of the heater (See Figure 16). Flue Pipe Holder Fig. 16 Step 14: Secure the Heater Insert the narrow ends of the 2 wall clamps into sockets on the rear of the heater. Loosen the adjustment screws and extend the clamps until they touch the wall. Fasten the clamps to the wall with 2 #8x/i tapping screws. NOTE: If use of wall clamps is not feasible or practical, the heater should be secured by screws to floor through punched holes in spill tray. 14 SECTION E FUELING A WARNING: USE ONLY CRYSTAL CLEAR KEROSENE. NEVER USE GASOLINE, WHITE GAS, CAMP FUEL OR OTHER FLAMMABLE LIQUIDS. USE OF SUCH FUELS CAN RESULT IN AN EXPLOSIVE FIRE AND CAUSE SEVERE INJURY. Step 1: Lift Out the Capsule Fuel Tank To fill with fuel, open the tank cover and lift out the capsule fuel tank (see Figure 17). Turn the tank upside down, and remove the fuel cap. If the fuel cap is difficult to unscrew, press the valve in the center, and remove. "FULL" Fuel Level Fig. 18 Step 3: Reinstall the Capsule Fuel Tank Replace and tighten the fuel cap. To insure proper fuel flow, be sure the cap is secured correctly. Install the tank with the arrow pointing forward, and close the tank cover (see Figure 19). Fig. 17 Step 2: Using a Siphon A siphon is not included with your Monitor 422. You may obtain one from your Monitor dealer. To operate a siphon, insert the straight tube into the kerosene container. Insert the siphon's flexible hose into the capsule fuel tank (see Figure 18). Watch the fuel gauge on the capsule tank closely. As the fuel begins to near the full level (see Figure 18), stop the flow by turning the vent knob on top of the siphon counter-clockwise. Remove the siphon slowly to allow excess kerosene to drain back into the container. Fig. 19 NOTICE:Capsule tank use is NOT permitted Massachusetts and Connecticut. 15 in REFUELING EXTERNAL TANK INSTALLATION-Gravity Fed NOTE: When the red light marked "Empty" illuminates and flashes, a buzzer will sound for twenty seconds. The burner mode is changed to "Low" automatically, and then, the heater will shut off after 30 minutes. The remaining burning time is indicated at the display window. When using external tank, changes in heater installation and pipe connections are required. PREPARATION AT HEATER Stepl: Remove the capsule fuel tank, and the fuel filter from the fuel sump tank (see Figure 20). 30 min 20 sec •Burner shuts off.

Step 2: If kerosene has accumulated in the spill tray or in the chamber which holds the capsule fuel tank, clean with a towel or rag. Remove any flammable items situated near the heater or flue pipe. Step 3: Follow directions under "Fueling". FUELING OPTIONS AVAILABLE Fig. 20 In addition to the standard capsule tank, the following fueling options are available for use with your Monitor 422. 1. Gravity Fed Large Capacity External Tank: Practical for large heating needs where bulk delivery of kerosene is available. This system should be installed by a qualified plumber or fuel supply technician. 2. Large Capacity External Tank with Pump: For large heating needs where a gravity fed system is not practical. An electric suction pump, especially designed for use with your Monitor 422 heating system, is available from your dealer. When using a gravity fed tank or pumping system to supply fuel, the inlet pressure to the heater must not exceed 2.5 psi. NOTE: When using a separate fuel tank with your Monitor 422, the "Empty" light will NOT signal an empty tank. Watch the gauge on the tank to avoid running out of fuel. 16 Step 2: Remove fuel with the siphon, remaining fuel must be sucked up with the plastic syringe (see Figure 21). Fuel Sump Tank Plastic Syringe Fig. 21 Step 3: Wipe off the fuel sump tank with a towel or rag (see Figure 22). Step 4: Remove the nut at the rear lower side of the heater. Collect fuel draining from the heater into a container. Hold the nipple with a wrench and loosen the nut with the other wrench (see Figure 23).

Printed Wiring Board Lead Wires Color: Red/Brown Marking : "U" NOTE:Plug in male, female connectors to bypass circuit. Plug For Short Circuit Fig. 26 18 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.

Once desired temperature is displayed, press set button to lock into memory. The lights on the control panel will indicate the level of heater operation — low, medium or high. The heater will automatically change its heat output until the desired room temperature is reached. While it cycles, you may hear the circulation fan change speed. Depending on the output required to maintain the desired room temperature, the indicator lights will illuminate in the following pattern: BURNER MODE High H. Medium L. Medium Low Off LIGHT PATTERN 8 indicators — On 6 indicators — On 4 indicators — On 2 indicators — On *No lights on The heater will shut itself off temporarily when the desired room temperature has been reached and restart automatically when necessary to maintain room temperature. NOTE: The heater may display room temperature 4 degrees above set temperature, depending on heater load conditions, before shutting itself off. INSTRUCTIONS FOR ECONOMY PLUS MODE To engage the economy plus mode, simply press down the button labeled "Economy Plus", to disengage press again. NOTE:Operation switch must be "ON" and in manual mode. This feature minimizes the "ON" and "OFF" cycling of the unit by allowing it to overshoot the set temperature by 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). SECTION H SECTION I TURNING OFF THE HEATER RELIGHTING THE HEATER To turn off the heater, press the Operation Button to put it in the "Off" position (Figure 29).The operation light will go out, and the fuel flow will stop.

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. Strainer Cover Drain Guide Container Fig. 33 Step 7: Storing the Heater During summer months or long periods when your heater will not be in operation, take the following steps: • Clean off the exterior cabinet with a damp cloth, and brush or vacuum dust from the grills. • Cover the heater to protect it from dust. • DO NOT DISASSEMBLE the heater or extension kits. Replacement of lost parts is an unnecessary expense. • Shut off fuel supply to unit. • Disconnect or shut off power supply to unit to prevent possible damage from lighting or power surges. 26 SECTION M TROUBLESHOOTING GUIDE Should symptoms appear during the operation of your heater, refer to the chart below, If you are unable to restore normal operation, contact your MPI dealer for service.
