Gas Line Connection
Check the gas type. Use only the gas type indicated on
the appliance rating plate. If the gas listed on the plate
is not the type of gas supplied, DO NOT INSTALL the
logset. Contact your dealer for the proper model.
Always use an external regulator for all LP appliances,
to reduce the supply tank pressure to a maximum of
14” w.c. This is in addition to the regulator fitted to the
heater.
The normal gas connection is made at the right side
(facing the unit). If a left-side connection is desired, the
connecting pipe may be directed under or behind the
rear of the appliance, to terminate at the right-hand side
for connection to the inlet of the appliance.
Connect the appliance to the gas line using fittings and
aluminum tubing provided.
Close the valve knob on the appliance, turn the main
gas supply valve ‘ON’, and carefully check all gas
connections for leaks, with a soapy water solution or a
sniffer. DO NOT TEST FOR LEAKS WITH AN OPEN
FLAME.
Upon completing your gas line connection, a small
amount of air will be in the gas lines. When first lighting
the pilot, it will take a few minutes for the lines to purge
themselves of air. Once the purging is complete, the
pilot and burner will light and operate as indicated in
this manual. Subsequent lightings of the appliance will
not require purging.
Check the inlet pressure to the appliance, to ensure
that it is as shown in the table on page 3. The minimum
is for the purpose of input adjustment.
The pressure is controlled by the regulator and should
be checked at the pressure test point located in the
control valve body. Access to the pressure test point is
obtained by removing all logs. (UVLX-M series only)
The pressure should be checked with the appliance
burning and the control set on ‘HIGH’.
The pressure regulator is preset and locked to avoid
tampering. If the pressure is not as specified, replace
the regulator. Refer to Replacement Parts.
After measuring the pressure, replace the test point
plug. Ensure there are no leaks, then place the logs in
their specified positions.
WARNING
Connection directly to an unregulated LP tank
can cause an explosion.
During the initial purging and subsequent light-
ings, never allow the gas valve control knob to
remain depressed in the ‘Pilot’ position without
lighting the pilot with a match or piezo ignitor.
There is a possibility of odor fade in LP. Never in-
stall an LP appliance or service line below grade
without a gas detector.
Positioning the Logs
The logs must be positioned on the grate and locating
pins, as shown in Figure 8. Make sure each bottom log
engages the locator pins on the grate, and top logs are
properly positioned in notches on tops of bottom logs.
Gas logs must be properly positioned or the appliance
will not function properly, and may result in soot accu-
mulation on the inside of the firebox and/or on the gas
logs. Make sure there is no yellow flame impinge-
ment on the logs which could result in excessive
carbon monoxide emissions and carboning.
The optional volcanic rock may be applied to the
hearth around the burner assembly.
Never place any other material on the burner.
WARNING
Failure to position the parts in accordance with
these diagrams or failure to use only parts spe-
cifically approved for use with this appliance may
result in property damage or personal injury.
