INSTALLATION
Continued
3. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas or opening main gas valve
located on or near gas meter for natural gas
or using compressed air.
4. Check all joints of gas supply piping system.
Apply noncorrosive leak detection fluid to all
joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Reconnect heater and equipment shutoff
valve to gas supply. Check reconnected fit-
tings for leaks.
Test Pressures Equal To or Less Than
1/2 PSIG (3.5 kPa)
1. Close equipment shutoff valve (see Figure 8).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas or opening main gas valve
located on or near gas meter for natural gas
or using compressed air.
3. Check all joints from gas meter to equipment
shutoff valve for natural gas or propane/LP
supply to equipment shutoff valve for propane/
LP (see Figure 9 or 10). Apply noncorrosive
leak detection fluid to all joints. Bubbles form-
ing show a leak.
4. Correct all leaks at once.

Connections
1. Open equipment shutoff valve (see Figure 8.)
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 appliance is in the
OFF position.
4. Check all joints from equipment shutoff valve
to gas control (see Figure 9 or 10). Apply
noncorrosive leak detection fluid to all joints.
Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light appliance (see
Operating Appliance
,
page 10) Check all other internal joints for
leaks.
7. Turn off appliance.
PLACEMENT OF LOOSE EMBERS
CAUTION: Do not place
any loose embers around pilot
assembly.
Two bags of loose embers are provided with this
unit. For this installation use the embers that are
approximately 1" square in size. If needed, larger
embers can be broken to size. These embers aid
in concealing the burner pan, directing flames
through the ember bed, quiet operation of the
unit and gives a natural random flame pattern (see
Figure 11, page 10).
Place embers as follows:
1. Place embers around the center ember bed or
ember pod.
2. Place individual embers on their edge (not flat)
along the top of the burner pan. This aids in
directing flames from the burner through the
ember bed.
Note:
Too many embers or embers placed flat
along burner pan can suppress the flames.
