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 appli-
ances, 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 appli-
ance.
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.
(UVL-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
lightings, 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
install 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 appli-
ance will not function properly, and may result in
soot accumulation on the inside of the firebox and/or
on the gas logs. Make sure there is no yellow
flame impingement 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.
WARNING
Failure to position the parts in accordance
with these diagrams or failure to use only
parts specifically approved for use with this
appliance may result in property damage or
personal injury.
