7. Check to make sure that the power cord is com-
pletely clear of the blower wheel and that there
are no other foreign objects in blower wheel. Also
double check all wire leads and make sure wire
routing is not pinched or in a precarious position.
Correct accordingly.
8. Turn on power to duplex outlet if previously
turned off per the warning in column 1,
page 19.
9. Plug in blower power cord to duplex outlet.
10. The blower will only run when the speed control
knob is in the ON position and the thermal switch
senses temperature after the fireplace begins to
heat up. The blower speed can be adjusted by
rotating the control knob. To turn off, turn knob
fully counterclockwise until it clicks off. If the
blower is ON and has been running with the
fireplace operating, the blower will continue to
run for a short time after the fireplace has been
turned off. As the thermal switch cools down, the
blower shuts down automatically.
11. Peel off the backing paper and stick the sup-
plied wiring diagram decal on the firebox bot-
tom approximately 12" in front of the blower
(see Figure 28, page 20).

INSTALLING GAS pIpING TO
FIREpLACE LOCATION
WARNING: A qualified
service person must connect
fireplace to gas supply. Follow
all local codes.
CAUTION: For propane/LP
units, never connect fireplace di
-
rectly to the propane/LP supply.
This heater requires an external
regulator (not supplied). Install
the external regulator between
the fireplace and propane/LP
supply.
WARNING: For natural gas,
never connect heater to private
(non-utility) gas wells. This gas
is commonly known as well-
head gas.
Installation Items Needed
Before installing fireplace, 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 connector
(if allowed by local codes)
* A CSA design-certified equipment shutoff
valve with 1/8" NPT tap is an acceptable alterna-
tive to test gauge connection. Purchase the CSA
design-certified equipment shutoff valve from
your retailer.
For propane/LP connection only, 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, fireplace regulator dam-
age could occur. Install external regulator with
the vent pointing down as shown in Figure 31,
page 22. Pointing the vent down protects it from
freezing rain or sleet.
