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 con-
tacting logs will create soot.
It is very important to install the logs exactly
as instructed. Do not modify logs. Only use
logs supplied with heater. Before installing
logs, make sure log alignment screws are in
place and straight.
