1. Open equipment shutoff valve (see Figure 15).
2. Open main gas valve located on or near gas meter for natural
gas or open propane/LP supply tank valve.

Each log is marked with a number. These numbers will help you
identify the log when installing. It is very important to install these
logs exactly as instructed. Do not modify logs. Only use logs
supplied with heater.
1. Locate pegs on the bottom of back log (#1). Slide these pegs into
the holes in the grate base behind the burner (see Figure 18).
INSTALLING LOGS, MODELS CGS2718P,
CGS2718N, CGS3124P AND CGS3124N
CAUTION: After installation and periodically there-
after, check to ensure that no flame comes in contact
with any log. With the heater set to High, check to see
if flames contact any log. If so, reposition logs ac-
cording to the log installation instructions in this
manual. Flames contacting logs will create soot.
