Installation Items Needed WARNING: You must secure this heater to fireplace floor. If not, heater will move when you adjust controls. Moving heater may cause a gas leak.

Manual background WARNING: If installing in a sunken fireplace, special care is needed. You must raise the fireplace floor to allow access to heater control panel. This will insure adequate air flow and guard against sooting. Raise fireplace floor with noncombus- tible material. Make sure mate- rial is secure.

IMPORTANT: Hold gas regulator with wrench when connecting flexible gas hose.

2.Locate mounting brackets, bolts, and nuts in hardware package. Attach mounting brackets to heater base (see Figure 13). Attach nuts finger tight.

3.Position heater base assembly in fire- place.
