in these instructions may be used in accordance with the manufacturer’s instructions and all codes and requirements of the authority having jurisdiction. Any modifications to this kit, or use of unauthorized components or ac- cessory items will void the manufacturer’s warranty, and may result in a hazardous condition.

FLUE OPENING

SPECIFICATIONS

Note: This vented appliance must be in- stalled only in a solid-fuel burning fireplace with a working flue and constructed of non- combustible material.

The charts in Figure 4 indicate technical information regarding the installation of your gas log set. Please make sure that all of the specifications shown are applicable be- fore installation is attempted.

The fireplace must include a working flue and venting system with the minimum open- ings shown in the Figure 4.

CHECK GAS TYPE

Use only natural gas. If your gas supply is not natural gas, you must install ON/OFF Safety Valve/Pilot Kit (see Accessories, page 19). Call dealer where you bought log set.

If the fireplace does not have a gas supply shut-off valve, one must be installed.

VENTING SPECIFICATIONS FOR INSTALLATION

The fireplace chimney flue and vent must be drafting properly. To check the vent for proper drafting: Light a tightly rolled news- paper on one end and place it at the inside front edge of the fireplace. Observe the smoke and be sure the vent is properly drawing it up the chimney. If the smoke spills out into the room, extinguish the flame and remove any obstruction until proper venting is achieved.

The chimney flue must remain open a mini- mum of 3" at all times during the operation of this log set.
