INSTALLING HEATER BASE ASSEMBLY
IMPORTANT: Make sure the heater burner is level. If heater is not level, heater
will not work properly.
Installation Items Needed
• hardware package (provided with heater)
• approved flexible gas hose (not provided) (if allowed by local codes)
• sealant resistant to propane (LP) gas, not provided
• electric drill with 3/16" drill bit
1. Apply pipe joint sealant lightly to male threads of the fitting to be threaded into
gas regulator. Connect approved flexible gas hose to gas regulator of heater
(see Figure 11, page 15).
IMPORTANT: Hold gas regulator with wrench when connecting flexible gas hose.
2. Locate masonary screws in hardware package.
3. Position heater base assembly in fireplace.
4. Mark screw locations through holes in mounting brackets (see Figure 12, page
15). If installing in a brick-bottom fireplace, mark screw locations in mortar
joint of bricks.
5. Remove heater base from fireplace.
6. Drill holes at marked locations using 3/16" drill bit.
7. Attach base assembly to fireplace floor using two masonry screws (in hardware
package) (see Figure 12, page 15).

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 soot-
ing. Raise fireplace floor with non-combustible material. Make
sure material is secure.
CAUTION
Do not pick up heater base assembly by the burner. This could
damage heater. Only handle base assembly by grates.
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.
