Fireplaces - Vented

Question 1: If you would like to add a blower to your unit

Answer: Blowers are optional accessories on most FMI Products gas appliances. Adding a blower is easily accomplished if 110 volt AC was provided to the electrical junction box of the fireplace, or a 110 volt AC outlet is installed near the fireplace or wall mount system at the time of initial installation.

Question 2: If your question concerns electricity supply

Answer: If your gas appliance model has a standing pilot it will operate during a power outage. If you have the optional blower installed in your gas appliance or the fireplace in which the log set is installed, the blower will not operate without electricity.

Question 3: If you have questions about how direct vent fireplaces vents

Answer: The direct vent systems have a fixed glass front, which seals the gas burner and combustion firebox off from your home. Air for combustion used by the fireplace comes from outside the home through a vent pipe. A smaller pipe inside the fresh air pipe carries all combustion products to the outside. The vent can be run horizontally through an outside wall or vertically through the roof.

Question 4: If your question concerns cleaning your gas appliance

Answer: The frequency of your gas appliance servicing and maintenance will depend on use and type of installation. Check the owner's manual for cleaning and maintenance information, or visit our tech tips page from the red link bar near the top of the webpage. FMI Products recommend you should have a qualified service technician perform an appliance check-up at the beginning of each heat season.

Question 5: If you wish to install a direct vent appliance in a bedroom or any other room

Answer: The installation of a direct vent appliance is allowable in a bedroom or any other room in by the National Fuel Gas Standards. Check your local codes to ensure there are no local restrictions.

Question 6: If your call concerns gas type conversion for Vented Gas Appliances

Answer: Most FMI Products vented models can be ordered in either natural or propane gasoperation (with the exception of vented logs). If you have purchased an appliance with the incorrect gas type or if you have received different type of fuel to your home, a conversion kit may be available. Contact your nearest dealer to determine if your model can be converted. Use only FMI Products approved conversion kits. All conversion kits must be installed by a qualified installer for certification of the fireplace to remain valid.

Question 7: If your question concerns operating a direct vent fireplace with the door assembly open

Answer: A direct vent fireplace is a sealed combustion fireplace. Doors must be shut and sealed for proper ventilation during the operation. If the glass door assembly and venting pipe are not properly seated, connected, and sealed, combustion by-products may leak into the home.

Question 8: If your question concerns the difference between an electronic ignition and a standing pilot

Answer: The standing pilot system is a self-contained millivolt system. You do not need a 110 power source to operate the fireplace or stove. The millivolt model will operate during a power outage. The electronic model will not operate when there is a power outage.

Question 9: If there is no spark at the pilot with a piezo ignitor

Answer: No spark at the pilot is an indication of a loose connection, a bad ground, or cracked ceramic around the electrode. (1) Check to ensure electrode wire is connected at the push button ignitor (where applicable) and at the electrode. Loose connections can be tightened by gently squeezing the loose connection with small pliers. (2) If the piezo is held in place by a nut, ensure the nut is tightened properly. (3) If the ceramic ignitor is cracked, it must be replaced.

Question 10: If you are experiencing pilot or burner outage

Answer: If you are experiencing pilot or burner outage, the gas appliance may need to be cleaned. Please refer to your owner’s manual for specific cleaning instructions for your model.

Question 11: If your pilot does not stay lit when releasing the control valve

Answer: The pilot flame heats a thermocouple that produces DC millivolts to energize the control valve. This allows the pilot to remain lit after releasing the control knob.

(1) A dirty pilot may not produce enough voltage to operate the control valve. Cleaning may be necessary. (2) Check pilot flame to ensure it is burning a solid blue flame. (3) A loose thermocouple connection may be at fault. To check connection, loosen thermocouple and tighten finger tight, then turn 1/4 turn with small wrench. If problem continues contact your nearest service center or qualified gas technician to have the unit serviced.

Question 12: To determine tank size for your LP/Propane appliance

Answer: LP/Propane wall mount space heaters, gas logs, and fireplace systems require a minimum 100 lb propane cylinder for proper operation. The vaporization rate of the fuel in smaller sized tanks can not keep up with the fuel requirements for the appliance. This will cause the liquid propane in the tank to freeze the regulator and this causes the appliance to shut down.

Question 13: If your question concerns venting configurations for vented fireplaces

Answer: Direct vent and B-vent (natural vent) appliances use a specific direct vent or b-vent pipe to vent combustion gases to the outdoors. Configurations for specific pipes vary depending on the individual installation. Consult the installation instructions for the specific model to ensure the proper pipe size and configuarion is used for your application.

Question 14: Where can I locate the model and serial number on the unit, and clearances?

Answer: The model and serial number can be found on the fireplace. The model and serial number is located on the right hand side in the screen pocket behind the screen. Model number, serial number and clearances to combustible information can be found on the rating plate.

Question 15: What is the inner and outer dimension of the wood burning pipe?

Answer: There are three sizes of wood burning pipe. We offer the 8DM, 10DM, and the 12DM. The 8DM pipe consists of an 8” inner pipe, and a 12-3/8” outer pipe. The 10DM pipe consists of a 10” inner pipe, and a 15” outer pipe. The 12DM pipe consists of a 12” inner pipe, and a 15” outer pipe.

A FMI Products hood must be installed when using a vent-free gas log heater and any glass doors must be removed.

Question 17: What is the ICC number for FMI Products wood burning fireplaces?

Answer: ESR-2542.

Question 18: What is the main purpose of an Outside Air Kit and is it required?

Answer: Outside air kits are available as an option and should be installed during the rough framing of the fireplace due to its location; Local code requirements may supersede this compliance.

Question 23: If you need help lighting your pilot

Answer: Check your gas supply shut off valve to make sure the valve is turned on. Most gas appliances have lighting instructions attached.
Wall mount heaters will have hang tags or a data sticker affixed to the cabinet. Gas logs and fireplace systems will have a sticker affixed or metal/vinyl cards with lighting instructions attached in the bottom compartment. If the instructions can not be located, please refer to the owner’s manual for your model appliance.

Press in and hold control knob. Press the ignitor button several times until pilot flame lights. Air may need to be purged from the line if the appliance has not been operated in a long time. If no fuel is detected at the pilot there is a blockage. Clean pilot with compressed air.
