4.Check all joints from equipment shutoff valve to control valve (see Figure 17). Apply a noncorrosive leak detection fluid to gas joints. Bubbles forming show a leak.

5.Correct all leaks at once.

6.Light heater (see Operating Heater, pages 17 and 18 [manu- ally-controlled models] or pages 18 through 20 [thermostati- cally-controlled models]). Check all other internal joints for leaks.

Make sure the front of the middle log is resting on the tabs of

 

the grate base and the cutout area is centered over the burner

 

“U” bend.

INSTALLING LOGS

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.
