PLEASANT HEARTH VFF-PH20NG (01) PDF Document

The specifications for the PLEASANT HEARTH VFF-PH20NG Series (Natural Gas) are as follows:

If the gas pressure is too low, you may experience the following symptoms:

• The pilot will not stay lit.

• The burners will have delayed ignition.

• The fireplace will not produce the specified heat.

• For propane/LP units, the propane/LP gas supply may be low.

If you feel your gas pressure is too low, contact your local natural or propane/LP gas supplier.

Follow these steps to assemble the hood if required:

1. If equipped, lift the fireplace screen up and pull out to remove. Set the screen aside until installation has been completed.

2. Cut two plastic straps to remove the log from the firebox cavity. Set the log aside.

3. If installing an optional blower, do so now following the instructions provided with the blower.

4. Locate four black Phillips sheet metal screws in the hardware packet.

5. Slide the hood between the louver and firebox top and align the screw holes.

6. Insert the screws and tighten them firmly.

Note: Always have the screen in place before operating the fireplace to prevent excessive temperatures on fireplace surfaces.

You must determine if you have a confined or unconfined space to ensure adequate ventilation. Use the following method:

1. Determine the volume of the space: Length × Width × Height = cu. ft. (volume of space).

2. Divide the space volume by 50 cu. ft. to determine the maximum BTU/hr the space can support.

3. Add the BTU/hr of all fuel-burning appliances in the space (Vent-free heater, Gas water heater, Gas furnace, Vented gas heater, Gas heater logs, Other gas appliances).

4. Compare the maximum BTU/hr the space can support with the actual amount of BTU/hr used.

If the actual BTU/hr used is less than the maximum BTU/hr the space can support, the space is an unconfined space and needs no additional fresh air ventilation. If the actual BTU/hr used is more, the space is confined, and you must provide additional fresh air via adjoining rooms or venting directly to the outdoors.

Clearances to combustibles must be maintained as follows:

• Side Wall: 6 inches from the side of the fireplace cabinet.

• Ceiling: 36 inches minimum from the top of the fireplace opening to the ceiling.

• Furniture/Draperies: Keep curtains, furniture, clothing, or other flammable objects at least 42 inches from the front, top, or sides of the heater.

• Note: This heater is designed to sit directly on the mantel base provided.

If you have purchased the optional blower kit, follow these installation steps:

1. Remove the Blower Access Panel.

2. Mount the Blower onto the bottom of the Fireplace Top using 4 screws.

3. Attach the Power Cord to the Blower Access Panel.

4. Attach the Temperature Sensor to the Combustion Top using 2 sheet metal screws.

5. Insert the wires marked with AUTO, OFF, and MAN into the line slot on the right corner. Keep wires close to the bottom.

6. Insert two wires’ female plugs marked with T1 and T2 (black and yellow) into the two male ports on the Temperature Sensor.

7. Insert the female plug on the white power supply wire (marked with P1) into the corresponding male port (marked with P1).

8. Insert the female plug (marked with P2) into the corresponding male port on the black power supply wire (marked with P2).

9. Insert the blower link (male plug) into the power link (female port).

10. Bind wires with cable ties and attach cable ties in holes on the back of the Outer Casing.

11. Insert AUTO, OFF, MAN wires through the Rocker Switch opening.

12. Connect AUTO, OFF, MAN wires to the three corresponding male ports on the Rocker Switch. Match the “Auto” wire to the symbol “-” and the “Man” wire to the symbol “=”.

13. Push the Rocker Switch into the Control Panel and secure.

14. Check that all wires are secure and reattach the Blower Access Panel to the Outer Casing. Capture the Green Ground wire between the Access Plate and Outer Casing with the upper right screw.

A qualified service technician must connect the heater to the gas supply. Follow these guidelines:

1. Use only new black iron or steel pipe. Internally tinned copper tubing may be used in certain areas based on local codes.

2. Use pipe of 1/2 inch diameter or greater.

3. Install an equipment shutoff valve, union, and plugged 1/8-inch NPT tap upstream from the heater.

4. Apply pipe joint sealant lightly to male threads to prevent excess sealant from clogging heater valves. Use sealant resistant to the type of gas used.

5. Install a sediment trap in the supply line within reach for cleaning and where it is not likely to freeze.

6. Connect the gas piping to the external regulator (which must be installed). Ensure the regulator vent points down.

7. Tighten connections using an 8″ Adjustable Wrench and 8″ Pipe Wrench. Hold the gas regulator with a wrench when connecting to avoid damage.

Use only the logs provided with the heater. Each log is marked with a number.

1. Insert log #1 onto the rear row of pins on the base pan.

2. Insert log #2 onto the front left pin on the base pan.

3. Insert log #3 onto the front right pin on the base pan.

4. Insert log #4 onto the left pin of log #1 and the pin of log #2.

5. Insert log #5 onto the right pin of log #1 and the pin of log #3.

Test all gas piping and connections for leaks after installing or servicing. Never use an open flame.

1. Open the equipment shutoff valve and the gas supply tank valve.

2. Make sure the control knob of the heater is in the OFF position.

3. Apply a mixture of liquid soap and water to all joints from the equipment shutoff valve to the control valve.

4. If bubbles form, there may be a leak. Correct all leaks immediately.

5. Light the heater and check all other internal joints for leaks.

6. Turn off the heater after testing.

Follow these steps to light the appliance:

1. STOP! Read the safety information regarding gas smells.

2. Open the lower access panel located below the fireplace screen.

3. Turn the control knob clockwise to the “OFF” position.

4. Wait five (5) minutes to clear out any gas. Smell for gas, including near the floor. If you smell gas, STOP and follow safety instructions. If not, proceed.

5. Turn the control knob counterclockwise to the “PILOT” position. Depress the control knob.

6. With the control knob depressed, push down on the ignitor button until the pilot lights. The pilot is located behind the fireplace screen, centered near the rear of the burner.

7. Keep the control knob depressed for (30) seconds after the pilot lights. Release the control knob.

8. Turn the control knob counterclockwise to the desired setting.

9. Close the lower access panel.

If the pilot goes out, repeat steps 3 through 7. Wait (1) minute before attempting to light the pilot again.

1. Open the lower access panel located under the fireplace screen.

2. Turn the control knob clockwise to the “OFF” position.

3. Close the lower access panel.

Maintenance should be performed by a qualified service person. Turn off the heater and let it cool before servicing.

Burner and Pilot:

• Clean the unit every three months during operation.

• Keep the primary air inlet holes, burner tube, and pilot assembly clean and free of dust, dirt, lint, and pet hair.

• Use compressed air (no greater than 30 PSI) to clean these parts. Blow air through ports/slots and holes in the burner.

• Do not use a wire or needle to clean the ODS/pilot.

Cabinet:

• Use a vacuum cleaner or pressurized air to clean air passageways.

• Use a soft cloth dampened with a mild soap and water mixture to wipe the exterior cabinet.
