Monessen Hearth B-Vent Specialty Gas Fireplace System DESIGNER SERIES - Manual (Page 15)

Maintenance of the Appliance
Air flowing through the appliance will cause dust and lint to collect on the grate, burner and logs. Exessive
buildup of dust and lint can cause the pilot and burner to operate improperly and produce hazardous
levels of carbon monoxide, a poisonous gas. The appliance may produce carbon (soot) during operation.
This carbon (soot) may collect on some logs, some areas of the grate and on the fireplace and vent.
Slight carbon buildup is acceptable.
The following is a recommended monthly maintenance program:
1. Turn the gas OFF at the line cut-off valve and allow the appliance to cool.
2. Blow or vacuum all dust and lint out of the appliance, paying particular attention to the pilot, air shutter
end of the burner, air passage into and through the appliance and control.
3. Vacuum or brush away all dust, carbon or lint on the logs and grate.
4. Turn the gas ON at the line cut-off valve and light the appliance according to the isntructions on the
chain.
5. Check all piping, pilot tubing, and manifold connections for leaks with a soap and water or liquid leak
detecting solution. If any leaks are observed, turn the gas OFF immediately and make the necessary
repairs.
6. Light the pilot and visually inspect the flame appearance. Note: Any maintenance of the appliance
that requires disconnection of the appliance from the gas line or removal of the control, burner or pilot
should only be performed by a qualified person.
