2.Locate two masonry screws in hardware package.

3.Attach extension plates (left and right on 30" models only) to base by placing tabs into base slots. Use supplied screws (2) to secure extension plates to base (see Figure 12).

4.Place heater base in fireplace.

5.Place logs in their proper position on heater base (see Installing Logs, pages 15 and 16).

6.Center heater base and logs front-to-back and side-to-side in fireplace.

7.Carefully remove logs without moving heater base.

8.Mark screw locations through one hole on each side of the mounting bracket (see Figure 13). If installing in a brick-bot- tom fireplace, mark screw locations in mortar joint of bricks.

9.Remove heater base from fireplace. If installing optional con- trol accessories, do so at this time. Follow all directions pro- vided with accessory.

10.Drill holes at marked locations using 3/16" drill bit.

11.Attach base assembly to fireplace floor using two masonry screws (in hardware package).

WARNING: This appliance requires a 1/2" NPT (National Pipe Thread) inlet connection to the pres- sure regulator.

WARNING: A qualified service person must con- nect heater to gas supply. Follow all local codes.

CAUTION: For propane/LP gas, never connect heater directly to the propane/LP supply. This heater requires an external regulator (not supplied). Install the external regulator between the heater and pro- pane/LP supply.

Installation Items Needed

Before installing heater, make sure you have the items listed below.

•external regulator for propane/LP only (supplied by installer)

•piping (check local codes)

•sealant (resistant to propane/LP gas)

•equipment shutoff valve *

•test gauge connection *

•sediment trap

•tee joint

•pipe wrench

*A CSA design-certified equipment shutoff valve with 1/8" NPT tap is an acceptable alternative to test gauge connection. Purchase the optional CSA design-certified equipment shutoff valve from your dealer. See Accessories, page 34.

For propane/LP only, the installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11 and 14 inches of water. If you do not reduce incoming gas pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 14, page 13. Pointing the vent down protects it from freezing rain or sleet.

WARNING: For natural gas, never connect heater to private (non-utility) gas wells. This gas is com- monly known as wellhead gas.

CAUTION: Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2" inside diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of volume will occur.
