190 mv DC CHECKING THERMOPILE FOR PROPER VOLTAGE Place the leads of the multimeter on the TP/TH and TP terminals on the valve as shown. With the switch in the “ON” position, the readings should be approximately 190mV DC (this an average reading) or greater for proper Thermopile operation. The main burners may not come ON if the readings are les[...]

2) PILOT WILL NOT STAY LIT Use a manometer on the inlet side of the valve to measure gas pressure. Adjust inlet pressure or contact your gas supplier. Make sure the gas pressure is correct for type of fuel you are using. SEE PAGE 5 FIGURE 7. Thermocouple should be the same height as the pilot hood. Make sure pilot flame is engulfing the top 3/8” [...]

MAIN BURNERS WILL NOT LIGHT CON’T. Bypass spill switch with a j umper wire as shown. If the unit starts, replace the spill switch. DO NOT LEAVE BY PASSED IN. Check spill switch operation on B-vented models only SEE PAGE 10 FIGURE 9. Check the “ON-OFF” switch and thermostat for proper operation. Use a jumper wire. If the unit starts, replace s[...]

Adjust pilot if necessary. Make sure pilot flame engulfs the thermopile and does “NOT” have a yellow luminous flame. SEE PAGE 4 FIGURE 4. 4) MAIN BURNERS WILL NOT STAY LIT Check outlet gas pressure. Check for clogged pilot injector or blocked air inlet. Using a multimeter check thermopile. If not constant replace thermopile. Make sure millivolt[...]

5) SOOTING Make sure log placement is in the correct location. Correct to manufactures specifications. Correct if necessary. Outside air supply may be required on B-vented models. Make sure there is sufficient air supply. Check air shutter on the venturi tube for proper primary air adjustment. SEE PAGE 16. Increase primary air. Open air shutter. Ma[...]

IF THE AIR SHUTTER IS OPENED WIDER, THE FLAME COULD APPEAR ALMOST ALL BLUE WITH FLAME LIFTING BEING THE END RESULT IF OPENED TOO MUCH WITH THE AIR SHUTTER SET PROPERLY, THE FLAME WILL SIT ON THE BURNER PORT AND THE FLAME PATTERN WILL START AT THE BOTTOM WITH A BLUE FLAME THEN TURNING TO A WHITE ALMOST Y ELLOW FLAME WITH A SLIGHT ORANGE EDGE AS THE [...]

6) FLAME LIFTING A) B-VENTED MODELS Adjust air shutter, by closing shutter. DO NOT GO TOO FAR OR THE UNIT WILL SOOT. Check air shutter on the burner tube (venturi). Make sure there are no leaks in the venting system. Seal venting if necessary. Improper venting configuration. Correct if necessary. Make sure that manifold (outlet). Pressure is correc[...]

B) DIRECT VENT MODELS Check air shutter on the burner tube (venturi). Adjust air shutter. Close until flame sits onto the burner ports. Seal exhaust tube with high temperature silicone. Also make sure that combustion air pipe is sealed. Make sure there are no leaks in the venting system. Make sure the unit is not recirculating flue products. Check [...]

Check to make sure that the fan is plugged in. 7) BLOWER DIAGNOSIS ALL MODELS Make sure the fan control knob is in the “ON” position. Make sure the two wires are connected to the fan temperature sensor. Make sure that the two wires are connected to the blower. Make sure there are no broken, damaged or frayed wires. Make sure that the fan sensor[...]
