INSTALLING HEATER BASE ASSEMBLY
IMPORTANT: Make sure the heater burners are 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" masonry 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 10, page 14).
2. Locate masonary screws in hardware package.
3. Position heater base assembly in fireplace.
4. Mark screw locations through holes in mounting flanges (see Figure 11, page

joint of bricks.
5. Remove heater base from fireplace.
6. Drill holes at marked locations using 3/16" masonry drill bit.
7. Attach base assembly to fireplace floor using two masonry screws (in hardware
package) (see Figure 11, page 14).

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.
