2. Pressurize supply piping system by either using compressed
air or opening main gas valve located on or near gas meter.
3. Check all joints from gas meter to equipment shutoff valve (see
Figure 8). Apply a noncorrosive leak detection fluid to gas joints.
Bubbles forming show a leak.
4. Correct all leaks at once.

dance with these diagrams or failure to use only parts
specifically approved with this heater may result in
property damage or personal injury.
INSTALLING LOGS
It is very important to install the logs exactly as instructed. Do not
modify logs. Only use logs supplied with heater.
Place one-piece log set on grate to fit as illustrated in Figure 10.
Make sure log sits flat on firebox floor (see Figure 9).
IMPORTANT: Make sure log does not cover any burner ports (see
Figure 10).
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.
