IMPORTANT INFORMATION FOR THE INSTALLATION OF THIS GAS LOG SET
Thefollowingareguidelinesforplacingagaslogsetinareplacethathasarestrictivebarrieralongthebottomfrontopen-
ingofthereplace.Someexamplesofbarriersareglass/screendoorframesandsunken/recessedreplaces.
Glass door frames
with adjustable
louvers should have
the lovers fully open
while the unit is in
operation.
Height of restrictive barrier
caused by glass door frames,
recessed fireplaces, etc. from
the base or bottom surface of the
unit. (See Table).
The log set should be
placed against or as near
as possible to the rear wall
of the fireplace/firebox.
Depth of fireplace/firebox.
(See Table).
Figure 3 - Reference Drawing of a Log Set in an Enclosure
NOTE: Non combustible material such as refractory brick may be used to line the floor of the fireplace
in order to raise the height of the gas log set in relation to a restrictive barrier. If the unit is raised, THE
MINIMUM HEIGHT DIMENSION LISTED IN THE HOMEOWNER’S MANUAL MUST NOT BE EXCEEDED.
NOTE: If the log set is equipped with a remote receiver, a restrictive barrier may reduce the battery life
by increasing the ambient temperature inside the fireplace. Placement of the receiver outside of the
fireplace will extend the battery life.

IMPORTANT: Holdapplianceregulatorrmlywithawrenchtopreventmovementwhenconnectingtoinletpiping.
Check gas type: The gas supply must be the same as stated on the gas logs rating plate. If the gas supply is different, DO
NOT INSTALL THE GAS LOGS. Contact your dealer for the correct model.
Always use an external regulator for all propane/LPG gas logs only, to reduce the supply tank pressure to a maximum of
13"W.C.Thisisinadditiontotheregulatorttedtothegaslogset.Highpressurenaturalgassystemsrequirearegulator
to reduce supply pressure to 10" W.C.
Locations that the Pressure Tapping
Point May be Installed
NOTICE
A qualified gas appliance installer
must connect the appliance to the
gas supply. Consult all local codes
before installation.
CAUTION
Use new black iron pipe, steel pipe, copper tubing, or internally tinned copper tubing.
Copper or internally tinned copper tubing can only be used according to the National
Fuel Gas Code, section 2.6.3, providing gas meets sulfide limits, and where permitted by
local codes. Gas piping system must be sized to provide minimum inlet pressure (listed
on Data Plate) at the maximum flow rate (BTU/Hr). Undue pressure loss will occur if the
pipe is too small.
A manual shutoff valve must be installed upstream of the appliance. Union tee and
plugged 1/8" NPT pressure tapping point should be installed upstream of the appliance.
See Figure 5.
WARNING
Connecting directly to an
unregulated propane/LPG tank
can cause an explosion

CONNECTING THE GAS
The heater gas inlet connection is 3/8" NPT at the regulator, inlet on the right side facing the gas log. If a left side connection
is required, the connecting pipe may be led under the rear of the gas logs or behind the grate for connection to the inlet.
NOTE: The millivolt valve has an internal regulator, thus the incoming gas line connects directly to
the valve.
Test all gas joints from the gas meter to the appliance regulator for leaks using a gas analyzer or soap and water solution after
completing connection. DO NOT USE AN OPEN FLAME.
Check the gas pressure with the appliance burning.
