CHECKING GAS
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
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Fig- ure 15).
2.Pressurize supply piping system by ei- ther using compressed air or opening propane/LP supply tank valve.
3.Check all joints from propane/LP sup- ply tank to equipment shutoff valve (see Figure 16). Apply mixture of liquid soap and water to gas joints. Bubbles forming show a leak.
4.Correct all leaks at once.
Pressure Testing Heater Gas Connections
1. | Open equipment shutoff valve (see |
| Figure 15). |
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 16).Ap- |
| ply mixture of liquid soap and water to |
| gas joints. Bubbles forming show a leak. |
5. | Correct all leaks at once. |
6. | Light heater (see Operating Heater, |

CAUTION: Make sure exter- nal regulator has been installed between propane/LP supply and heater. See guidelines under Con- necting to Gas Supply, page 11.
Pressure Testing gas Supply Piping system
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
1.Disconnect appliance with its appliance main gas valve (control valve) and equipment shutoff valve from gas sup- ply piping. Pressures in excess of 1/2 psig will damage heater regulator.
2.Cap off open end of gas pipe where equipment shutoff valve was con- nected.
3.Pressurize supply piping system by ei- ther using compressed air or opening propane/LP supply tank valve.
4.Check all joints of gas supply piping system. Apply mixture of liquid soap and water to gas joints. Bubbles form- ing show a leak.
5.Correct all leaks at once.
6.Reconnect heater and equipment shutoff valve to gas supply. Check re- connected fittings for leaks.
