INSTALLATION
Installing Heater Base Assembly (Cont.)
Connecting To Gas Supply
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
Note:
Install optional remote receiver and hand-held remote kit (see
Accessories, page 28) before installing gas log heater. See installa-
tion instructions included with the kit.
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).
2. Locate masonry screws in hardware package.
3. Position heater base assembly in fireplace.
4. Place logs in their proper positions on heater base.
5. Center heater base and logs front-to-back and side-to-side in
fireplace.
6. Carefully remove logs without moving heater base.
7. Mark screw locations through holes in mounting flanges (see
Figure 12). If installing in a brick-bottom fireplace, mark screw
locations in mortar joint of bricks.
8. Remove heater base from fireplace.
9. Drill holes at marked locations using 3/16" masonry drill bit.
10. Attach base assembly to fireplace floor using two masonry
screws (in hardware package) (see Figure 12).
11. Connect to gas supply. See Connecting To Gas Supply.

Installation Items Needed
Before installing heater, make sure you have the items listed below.
• 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 28.
For propane/LP units, 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 13, page 12. Pointing the vent down protects it from
freezing rain or sleet.
CONNECTING TO GAS SUPPLY
WARNING: A qualified service person must con-
nect heater to gas supply. Follow all local codes.
CAUTION: Never connect propane/LP heater di-
rectly to the propane/LP supply. This heater requires an
external regulator (not supplied). Install the external
regulator between the heater and propane/LP supply.
WARNING: This appliance requires a 1/2" NPT
(National Pipe Thread) inlet connection to the pres-
sure regulator.
WARNING: Never connect natural gas heater to
private (non-utility) gas wells. This gas is commonly
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" diam-
eter or greater to allow proper gas volume to heater. If
pipe is too small, undue loss of volume will occur.
