threads of gas fitting (provided). Connect
approved flexible gas hose to gas regula
-
tor of heater (see Figure 11).
IMPORTANT:
Hold gas regulator with
wrench when connecting flexible gas hose.
2.
Position heater base assembly in fireplace.
3. Mark screw locations through holes in
front panel of base (see Figure 12). If
installing in a brick-bottom fireplace, mark
screw locations in mortar joint of bricks.
4. Remove heater base from fireplace.
5. Drill holes at marked locations using 3/16"
drill bit.
6. Attach base, through holes in front panel
of base, to fireplace floor using masonry
screws provided in hardware package
(see Figure 12).
7. Connect to gas supply. See

CONNECTING TO GAS SUPPLY
WARNING: This appliance
requires a 1/2" NPT (National
Pipe Thread) inlet connection to
the pressure regulator.
WARNING: A qualified service
person must connect heater to gas
supply. Follow all local codes.
CAUTION: Never connect
propane/LP fireplace directly
to the propane/LP supply. This
heater requires an external regu-
lator (not supplied). Install the
external regulator between the
heater and propane/LP supply.
WARNING: Never connect
natural gas fireplace to private
(non-utility) gas wells. This
gas is commonly known as
wellhead gas.
Installation Items Needed
Before installing heater, make sure you have
the items listed below.
• external regulator (supplied by installer)
• piping (check local codes)
• sealant (resistant to propane/LP gas)
• equipment shutoff valve *
• test gauge connection *
• sediment trap
• tee joint
• pipe wrench
• approved flexible gas line with gas con
-
nector (if allowed by local codes) (not
provided)
* A CSA design-certified equipment shutoff
valve with 1/8" NPT tap is an acceptable al-
ternative to test gauge connection. Purchase
the optional CSA design-certified equipment
shutoff valve from your dealer.
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" of water. If you do not re-
duce incoming gas pressure, heater regulator
damage could occur. Install external regulator
with the vent pointing down as shown in Figure
13, page 14. Pointing the vent down protects
it from freezing rain or sleet.
