BURNER INSTALLATION (Cont.)
The burner system and its 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
psig (3.5 kPa). The burner system must be
isolated from the gas-supply piping system by closing its equipment shutoff valve during any pressure testing
of the gas-supply piping system at test pressures equal to or less than
1
/
2
psig (3.5 kPa). This is accomplished
by closing the gas-supply line valve.
IMPORTANT
For all valves, the air MUST be purged from the gas line before the pilot will light and burn properly. The
time needed to purge will depend on the length of the gas line to the unit and the amount of time since
the unit or gas line was last used. It may take several minutes before all the air is purged and the pilot
will light and burn properly. Reference the LIGHTING INSTRUCTIONS section in this manual.
IMPORTANT
Check the gas pressure with the system burning and the control fully ON.
REMOTE SYSTEM (if equipped)
If the unit is equipped with a remote; read and follow the
separate instructions (packed with the remote) for complete
remote installation.
CONTROL SETTINGS
We recommend that before you install the decorative media,
you familiarize yourself with the control valve layout. This will
help you to be confi dent operating the burner system when
fully installed. See Fig. 18-1 for typical control positions.
