7. Check to make sure that the power cord is
completely 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 previ-
ously 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
directly 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 wellhead 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.
