1. Close equipment shutoff valve (see Figure 17).
2. Pressurize supply piping system by either using compressed
air or opening propane/LP supply tank valve.
3. Check all joints from propane/LP supply tank to equipment
shutoff valve (see Figure 18). Apply a noncorrosive leak de-
tection fluid to all joints. Bubbles forming show a leak.
4. Correct all leaks at once.
Pressure Testing Heater Gas Connections
1. Open equipment shutoff valve (see Figure 17).
2. 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 control valve
(see Figure 18). Apply a 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 19 and 20 [manu-
ally-controlled models] or pages 20 and 21 [thermostatically-
controlled models]). Check all other internal joints for leaks.
7. Turn off heater (see To Turn Off Gas to Appliance, page 20
[manually-controlled models] or page 21 [thermostatically-con-
trolled models]).
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.
INSTALLING LOGS
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 pins on the bottom of back log (#1). Slide these pins into
the holes in the grate base behind the burner (see Figure 19).

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
according to the log installation instructions in this
manual. Flames contacting logs will create soot.
