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.

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.

CAUTION: Do not pick up heater base assembly by burners. This could damage heater. Only handle base assembly by grates.

IMPORTANT: Make sure the heater burn- ers are level. If heater is not level, heater will not work properly. For thermostat models, avoid damage to thermostat bulb. Avoid nicks or sharp bends in thermostat bulb wire. Keep thermostat bulb in mounting bracket.

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 12, page 11). Attach nuts finger tight.

3.Position heater base assembly in fire- place.

4.Mark screw locations through holes in mounting brackets. If installing in a brick-bottom fireplace, mark screw lo- cations in mortar joint of bricks.
