Log Placement

WARNING

Logs get very hot and will remain hot up to one hour after gas supply is turned off. Handle only when logs are cool. Turn off all electricity to the appliance before you install grate and logs.

WARNING

This appliance is not meant to burn wood. Any attempt to do so could cause irreparable damage to your appliance and prove hazardous to your safety.

WARNING

The size and position on the log set IS Critical to give your appliance a safe, reliable and attractive ﬂ ame pattern. Any attempt to use a different log set in the ﬁ replace will void the Warranty and will result in incomplete combustion, sooting, and poor ﬂ ame quality.

Figure 10

Burner Flame Appearance - Model MPB-3328

Initial Installation Considerations

The packaged logs are located within the ﬁ rebox. The decorative volcanic stone and glowing embers are packaged separately in plastic bags located in the control area of the ﬁ replace.

If the logs are being installed for the ﬁ rst time, the following paragraphs apply:

DO NOT attempt to install the logs until the appliance installation has been completed, the gas line connected and tested for leaks and the initial burner operation has been checked out.

Proper twig placement is critical to prevent sooting. Twigs should be placed in the gaps between the ﬂ ame peaks and should be positioned so that at no time they impinge the ﬂ ames.

Step 1. Remove the appliance front door. Step 2. Remove the log set from the interior

of the ﬁ replace.

Step 3. Remove the logs from their packaging. Handle logs carefully to prevent breakage. Step 4. MPB-4035 & MPB-4540 Models

- Remove the restraining strap from the grate

tines. Ensure the grate is fully inserted into the holes on the ﬁ rebox rear panel and over the indents on the ﬁ rebox ﬂ oor.

Glowing Embers, Vermiculite, Decorative Volcanic Stone And Log Placement Instructions:

Step 1. Separate the Glowing Embers (Rockwool) into pieces about

the size of a quarter (see Figure 13). Keep the pieces ﬂ uffed up, not matted.

MPB-3328 & MPB-3530 Models -

Distribute these pieces over the burner as shown in Figure 14. Do not use more than is shown. The glowing embers should not be placed directly over the large burner slots as shown in Figure 14.

MPB-4035 & MPB-4540 Models -

Place the center log (Log No. 1) on the burner as shown on Page 14. Distribute the glowing ember pieces at the front of the burner as shown in Figure 15. Do not use more than is shown. The glowing embers should not be placed directly over the large burner slots as shown in

Figure 15.

Note: This appliance is provided with enough Glowing Embers for several applications; do not feel compelled to use all that is in a new bag. For best glowing effect, replace the ember material annually. Replacement Glowing Embers are available (Catalogue Number 88L53).

Step 2. Mound up a portion of the vermiculite (light colored material) in front of the burner and grate. Sprinkle the dark colored decorative volcanic stone on top of the vermiculite in a pleasing pattern. For best results, spread in a non-uniform manner while ensuring complete coverage of the black sheet metal surface.

See Figure 14 - MPB-3328 or MPB-3530, or Figure 15 - MPB-4035 or MPB-4540 models.

Note: Do Not place vermiculite or decorative volcanic stone on top of the gas burner where it will block the burner ports.

TROUBLESHOOTING

Note: Before troubleshooting the gas control system, Ensure external gas shut off valve, located at gas supply inlet, (and wall switch, iff applicable), is in the “ON” position. Important: Valve system troubleshooting should only be accomplished by a qualiﬁ ed service technician.

TROUBLESHOOTING GUIDE - MILLIVOLT GAS CONTROL SYSTEM

SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION

1. Spark Igniter will not light pilot after

repeated triggering of Igniter button.

2. Pilot will not stay lit after

carefully following the lighting instructions.

3. Pilot burning, no gas to burner, Valve

knob “ON,” Wall Switch “ON.”

4. Frequent pilot/burner outage prob-

lem.

A. Defective igniter (no spark at electrode).

B. Defective or misaligned electrode at pilot

(spark at electrode).

C. Gas supply pressure errant.

D. Pilot oriﬁ ce plugged. A. Defective pilot generator

(thermocouple).

A. Limit Switch defective.

B. Wall switch or wires defective.

C. Thermopile may not be generating suf-

ﬁ cient millivoltage.

D. Plugged burner oriﬁ ce. A. Pilot ﬂ ame may be too low or blowing (high)

causing the pilot/valve safety to drop out.

Check for spark at electrode and pilot; if no spark and electrode wire is properly connected, replace Igniter.

Using a match, light pilot. If pilot lights, turn off pilot and trigger the igniter button again. If pilot lights, an improper gas mixture caused the bad lighting and a longer purge period is recommended. If pilot will not light – check gap at electrode and pilot – should be 1/8" to have a strong spark. If gap measures 1/8", replace pilot (see Figure 8 on Page 9).

Check inlet gas pressure. It should be within the limits as marked on the rating plate.

Clean or replace pilot oriﬁ ce. Check pilot ﬂ ame, it must impinge on thermocouple

(see Figure 8 on Page 9). Clean and/or adjust pilot for maximum ﬂ ame impingement on thermocouple. Ensure that the connection between the valve and thermocouple are tight and secure.

Isolate the “limit” switch. Disconnect the wires from the “ON/OFF” switch and the valve (label wires for reattachment). Test for continuity with a multimeter. If continuity is not indicated, switch is defective and must be replaced.

Check wall switch and wires for proper connections. Jumper wire across terminals at wall switch, if burner comes on, replace defective wall switch. If okay, jumper wires across wall switch wires at valve, if burner comes on, wires are faulty or connections are bad.

Check thermopile with millivolt meter. Take reading at thermopile terminals of gas valve. Should read 325 millivolts minimum with optional wall switch “OFF.” Replace faulty thermopile if reading is below speciﬁ ed minimum.

Check burner oriﬁ ce for stoppage and remove. Clean and/or adjust pilot ﬂ ame for maximum ﬂ ame

impingement on thermocouple (see Figures 8 on

Page 9).

TROUBLESHOOTING GUIDE - ELECTRONIC IGNITION SYSTEM

SYMPTOM POSSIBLE CAUSES CORRECTIVE ACTION

1. Burner will not light. A. Faulty Valve System.

B. “OFF/ON” or wall switch defective.

2. Burners come “ON,” then turns “OFF.” A. Burner oriﬁ ce plugged.

B. Obstructed vent system.

NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

See Below.

Disconnect the two black wires from the wire nuts. Test switch(s) for continuity with a multimeter. If continuity is not indicated, switch(s) is defective and must be replaced.

Note: Before replacing “OFF/ON” switch, Ensure to check wiring for loose connections or broken wires and repair as needed.

Check main burner oriﬁ ce(s) for blockage. Clean or replace.

Check vent system for obstructions.
