GAS PRESSURE CHECK
Check the inlet pressure to the burner to ensure that it is as
shown in the table below.
NOTE: The pressure check point is located on the right side of the valve facing burner, for SIT
Millivolt, and the left side for SIT Modulating.
The appliance and its appliance main gas valve must be disconnected from the gas supply
piping system during any pressure testing of that system at test pressures in excess of 1/2 psi
(3.5kPa).
The appliance must be isolated from the gas supply piping system by closing its equipment shut
-off valve during any pressure testing of the gas supply piping system at test pressures equal to
or less than 1/2 psi (3.5 kPa).

NOTE: On initial installation it may be necessary to bleed out air in the gas lines. Do this by
holding the control knob and turning the knob to the “PILOT” position for about 30 seconds.
To check the regulator pressure, remove the pressure tag plug at the left side of the regulator
facing the heater. The pressure should be checked with the heater burning and the control set
on high. After measuring the pressure, replace the pressure tap plug, ensuring that there are no
leaks.

WAR N I N G
This appliance is equipped for (natural or propane) gas.
Field conversion is not permitted.
Solid fuels shall not be burned in the same fireplace where an unvented room heater has
been installed.

then attached to the floor of the fireplace or firebox area beneath the appliance.
The label is a peel and stick label. Make sure the area is cleaned before attaching
the label to it.
“WARNING: This solid-fuel burning fireplace or listed ventless enclosure has been
converted for use with an unvented fireplace insert only. A solid-fuel burning
fireplace cannot be used for burning wood or solid fuels unless all original parts
have been replaced, and the fireplace re-approved by the authority having
jurisdiction. A ventless firebox enclosure cannot be used with an unvented gas log
unless all original parts have been replaced, and the ventless firebox enclosure re-
approved by the authority having jurisdiction.”
