CONNECTIONS
WARNING: Test all gas pip- ing and connections for leaks after installing or servicing. Cor- rect all leaks at once.
WARNING: Never use an open flame to check for a leak. Apply a mixture of liquid soap and water to all joints. Bubbles forming show a leak. Correct all leaks at once.
CAUTION: Make sure exter- nal regulator has been installed between propane/LP supply and
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Fig- ure 8).
2.Pressurize supply piping system by either using compressed air or opening propane/ LP supply tank valve.
3.Check all joints from gas meter to equip- ment shutoff valve (see Figure 9). Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak.

1.Open equipment shutoff valve (see Fig- ure 8).
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 9). Apply mixture of liquid soap and wa- ter to gas joints. Bubbles forming show a leak.

Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1. | Disconnect heater with its appliance |
| main gas valve (control valve) and |
| equipment shutoff valve from gas sup- |
| ply piping system. Pressures in excess |
| of 1/2 psig will damage heater regulator. |
2. | Cap off open end of gas pipe where |
| equipment shutoff valve was connected. |
3. | Pressurize supply piping system by ei- |

5. | Correct all leaks at once. |
6. | Reconnect heater and equipment |
