2. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas or opening main gas valve
located on or near gas meter for natural gas
or using compressed air.
3. Check all joints from gas meter for natural or
propane/LP supply to equipment shutoff valve

INSTALLING LOGS
WARNING: Failure to posi-
tion the parts in accordance with
these diagrams or failure to use
only parts specifically approved
with this heater may result in
property damage or personal
injury.
CAUTION: After installation
and periodically thereafter, check
to ensure that no yellow flame
comes in contact with any log.
With the heater set to HI, check to
see if flames contact any log. If so,
reposition logs according to the
log installation instructions in this
manual. Yellow flames contacting
logs will create soot.
It is very important to install the logs exactly as
instructed. Do not modify logs. Only use logs sup-
plied with heater. Before installing logs, make sure
log alignment screws are in place and straight.
6. Light heater (see Operating Heater, page 16).
Check all other internal joints for leaks.
7. Turn off heater (see To Turn Off Gas to Appli-
ance, page 17).
