1. Open equipment shutoff valve (see Figure 18).
2. Open main gas valve located on or near gas meter for natural
gas or open propane/LP supply tank valve.
3. Make sure control knob of heater is in the OFF position.
4. Check all joints from equipment shutoff valve to thermostat
gas valve (Thermostat-Controlled Models), to control valve
(Manually-Controlled Models), or to gas control (Remote-
Ready Models)(see Figures 19 and 20). Apply noncorrosive
leak detection fluid to all joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light heater (see Operating Heater, pages 16 through 21).
Check all other internal joints for leaks.
7. Turn off heater (see To Turn Off Gas to Appliance, page 17 for

INSTALLING LOGS
WARNING: Failure to position the parts in accor-
dance with these diagrams or failure to use only parts
specifically approved with this heater may result in
property damage or personal injury.
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. Place front log (#1 for 18", #1a and #1b for 24" and 30") on
top of the grate. Make sure the notches in the bottom of the log
fits over the grate prongs (see Figure 21, page 15). Push back
of logs flush with metal grate bar. Logs for 24" and 30" should
fit with ends touching and a small realistic crack in the center.
2. Rest middle log (#2) behind metal posts on front burner. Make
sure the grooves in the bottom of the log fit over the grate.
Bring the log forward next to the metal posts. The cutout in the
middle log must be on top (see Figure 22, page 15).
3. Slide the grooves in the back of the rear log (#3) against the
rear grate prongs. Make sure the peg on the log is on top (see
Figure 23, page 15).
4. Place the crossover log (#4) on the back log and the middle
log. Make sure the peg on the rear log is in the hole in the
bottom of the crossover log. The crossover log should fit in the
cutout of the middle log (see Figure 24, page 15).
