Vermont Casting VL18LP, VL24LP, VL21 When Used as a Heating Appliance, Maintenance and Safeguards

When Used as a Heating Appliance

1.This appliance is equipped with a modulating valve which provides variable control of heat output, from approximately 15,000 or 18,000 BTU/hr at the full counterclockwise LOW position, to 24,000, 32,000 or 35,000 BTU/hr at the HIGH position, depending on your appliance. See page 3 for output of your appli- ance.

2.When used as an unvented heater, maximum benefit will result when the fireplace flue damper is fully closed.

3.NOTE: For your safety, the appliance is equipped with an oxygen depletion sensor. This device senses the level of oxygen in the atmosphere and switches off the gas supply in case the level of oxygen falls below a safe level.

4.The appliance may be used as a heating appliance only if unvented heating appliances are permitted by local, state and city codes. In locations that do not allow unvented heaters, the chimney must have a permanent chimney opening of not less than 29 square inches.

Maintenance and Safeguards

Keep the control compartment, logs and burner area around the logs clean by vacuuming or brushing at least twice a year.

THE LOGS CAN GET VERY HOT. HANDLE ONLY WHEN COOL.

Always turn off gas to the pilot before cleaning. For relighting, refer to the lighting instructions.

The appliance and venting system (if used) should be inspected before initial use and at least annually by a qualified field service person.

Always keep the appliance area clear and free from combustible materials, gasoline and other flammable vapors and liquids.

Never obstruct the flow of combustion and ventilation air. Keep the front of the appliance clear of all obstacles and materials.

Leave clearance of at least 36” from the front of the fireplace.

Although your gas logs are very realistic in appearance, the fireplace must not be used for burning any solid fuels.

To avoid irreparable damage to the appliance or per- sonal injury, matches, paper, garbage or any other material must not be placed or thrown on top of the logs or into the flames.

To avoid personal injury, do not touch hot surfaces when the appliance is operating. Touch only the valve control knob. Avoid contact with the grate feet or prongs, or any other part which may be very hot.

Always ensure that the fireplace screen is closed when the appliance is operating.

Any safety screen or guard removed for servicing the appliance must be replaced before operating the appli- ance.

Close supervision is necessary when the appliance is being operated near children.

The appliance is intended for use as a gas heater mounted in a vented or unvented fireplace as described in the installation sections of these instructions. It should not be used for any other purpose.

Inspecting the Venting System

A vented fireplace venting system is designed and con- structed to develop a positive flow adequate to remove flue gasses to the outside atmosphere. See vented fireplace installation instructions.

Any foreign objects in the venting system, except those designed specifically for the venting system, may cause spillage of the flue gasses into the room. In extreme situations, carbon monoxide poisoning or suffocation may occur.

Periodic examination and cleaning of the venting system of the solid-fuel burning fireplace must be done frequently by the home owner or a qualified agency.

VL System Maintenance

The VL burner/control systems consist of:

Chassis

Gas Orifice

Grate Assembly

VL18 - four (4) decorative gas logs VL21 - five (5) decorative gas logs VL24 - six (6) decorative gas logs

Gas Valve Assembly

Pressure Regulator

Most of these components require only occasional checkup and cleaning. Some may require adjustment. If repair is required, it should be performed by a qualified technician.

In order to properly clean the burner and pilot assembly, turn off the gas to the unit, remove the logs exposing the burner and pilot assembly. Clean all foreign materi- als from top of burner. Check to make sure that burner parts are clean. Visually inspect pilot. Brush or blow away any dust or lint accumulations.

To obtain proper operation, it is imperative that the pilot and main burner flame characteristics are steady, not lifting or floating. Refer to Figure 10 for proper main burner flame appearance and Figure 11 or 12 for proper pilot flame appearance.
