CHECKING GAS CONNECTIONS

WARNING: Test all gas pip- ing and connections, internal and external to unit, for leaks after installing or servicing. Cor- rect all leaks at once.

WARNING: Never use an

2.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve lo- cated 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 sup- ply to equipment shutoff valve for propane/LP (see Figures 22 and 23). Apply noncorrosive leak detection fluid to all joints. Bubbles form- ing show a leak.

CAUTION: Make sure exter- nal regulator has been installed between propane/LP supply and fireplace. See guidelines under Connecting Fireplace to Gas Supply, page 14.

Pressure Testing Gas Supply Piping System

Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)

1.Disconnect fireplace with its main gas valve (control valve) and equipment shutoff valve from gas supply piping system. Pressures in excess of 1/2 psig will damage fireplace regulator.

2.Cap off open end of gas pipe where equip- ment shutoff valve was connected.

3.Pressurize supply piping system by either opening propane/LP supply tank valve for propane/LP gas or opening main gas valve lo- cated 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 fireplace 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 21).
