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 open flame to check for a leak. Apply a noncorrosive leak de- tection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.
CAUTION: Make sure external regulator has been installed be- tweenpropane/LPsupplyandfire- place. See guidelines under Con- necting to Gas Supply, page 16.
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 supply piping. Pres- sures in excess of 1/2 psig will damage fire- place 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 a noncorrosive leak detection fluid to gas joints. Bubbles forming show a leak.
5.Correct all leaks at once.
6.Reconnect heater and equipment shutoff valve to gas supply. Check reconnected fittings for leaks.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
1.Close equipment shutoff valve (see Figure 26).
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 for natural or propane/LP supply to equipment shutoff valve (see Figures 27 and 28, page 19). Apply a non- corrosive leak detection fluid to gas joints. Bubbles forming show a leak.
4.Correct all leaks at once.
Pressure Testing Fireplace Gas Connections
1.Open equipment shutoff valve (see Figure 26).
2.Open main gas valve located on or near gas meter for natural gas or open propane/LP sup- ply tank valve.
3.Make sure control knob of fireplace is in the OFF position.
4.Check all joints from equipment shutoff valve to thermostat gas valve (see Figures 27 and 28, page 19). Apply a noncorrosive leak detection fluid to gas joints. Bubbles forming show a leak.
5.Correct all leaks at once.
6.Light fireplace (see Operating Fireplace, pages 19 and 21). Check all other internal joints for leaks.
7.Turn off fireplace (see To Turn Off Gas to Appliance, page 20).
8.Replace front panel.
