INSTALLATION

Continued

CAUTION: Make sure exter- nal regulator has been installed between propane/LPsupply and fireplace. See guidelines under Connecting 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 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 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 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 25).

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 sup- ply to equipment shutoff valve for propane/LP

(see Figures 26 or 27). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.

4.Correct all leaks at once.

Connections

1. Open equipment shutoff valve (see Figure 25).

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 fireplace is in the OFF position.

4. Check all joints from equipment shutoff valve to gas regulator (Thermostat-Controlled Models) or to gas control valve (Remote- Ready Models) (see Figures 26 or 27). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.

5. Correct all leaks at once.

6. Light fireplace (see Operating Fireplace, page

21). Check all other internal joints for leaks.

7. Turn off fireplace (see To Turn Off Gas to Appli- ance, page 22 for Thermostat-Controlled Mod- els or page 24 for Remote-Ready Models).
