CHECK GAS TYPE

Use the correct gas type (natural or propane/LP) for your unit. If your gas supply is not correct, do not instal in fireplace. Call dealer where you bought the appliance for proper type of appliance.

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 newspaper on one end and place it at the inside front edge of the fireplace. Ob- serve 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 damper must be fixed open to provide a minimum of 43 sq. in. of free air opening during operation of this log set. A mul- tipurpose damper clamp is provided to fix the damper in position.

The minimum flue sizes shown in Figure 5 are based on a 6' chimney height using round pipe. Your minimum flue size will vary based on input rate and chimney height. Refer to the National Fuel Gas Code ANSI Z223.1/NFPA 54, Section 6.6, for details.

FLUE OPENING SPECIFICATIONS

Note: This vented appliance must be installed only in a solid-fuel burning fireplace with a working flue and constructed of noncom- bustible material.

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

The fireplace must include a working flue and venting system with the minimum openings shown in the Figure 5.
