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.

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.

PLACEMENT OF LOOSE EMBERS
CAUTION: Do not place any loose embers around pilot assembly.
Figure 8 - Equipment Shutoff Valve | Two bags of loose embers are provided with this | |||
|
| |||
Propane/LP |
| unit. For this installation use the embers that are | ||
Equipment | approximately 1" square in size. If needed, larger | |||
Supply Tank | ||||
Shutoff Valve | 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 | |
| Control Valve |
| ember pod. | |
| 2. | Place individual embers on their edge (not flat) | ||
| Location | |||
|
| along the top of the burner pan. This aids in | ||
