ply line and gas pressure at installation.
NOTE: Improper gas pressure can affect heater
performance, flame color, or cause pilot outage.

Connecting the Cord Set
The Clarity Fireplace Insert, when installed, must
be electrically grounded in accordance with local
codes or, in the absence of local codes, with the
the current edition of the National Electrical Code,
ANSI/NFPA 70 in the United States or the current
Canadian Electrical Code CSA .1 in Canada.
This appliance is equipped with a three-prong
(grounding) plug for protection against shock haz-
ard and should be plugged directly into a properly
grounded three-prong receptacle. Do not cut or
remove the grounding prong from the plug.
NOTE: The convection fan requires a 120 VAC
supply for operation, but the heater can be op-
erated without the fan as in the case of a power
outage.
Plug the 3-prong grounded electrical cord plug into
the wall outlet.
Connecting the Optional Thermostat
If the optional thermostat is used, it must be
plugged into the terminal strip located behind the
right side of the air inlet grill. It can be accessed by
sliding open the control access drawer.
When installing a millivolt control system, use
only a special low resistance thermostat. Do not use
a regular heating thermostat.
Be sure that all electrical connections are clean,
free from corrosion, and tight. Inspect connections
periodically to confirm that no corrosion has oc-
curred over time.
When properly installed and maintained, a mil-
livolt control system should give many years of
trouble-free service.
It is important to use wire of a gauge proper for the
length of the wire:
