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 equip-

 

ment shutoff valve was connected.

3.

Pressurize supply piping 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 com-

 

pressed air.

3.Make sure control knob of heater is in the OFF position.

4.Check all joints from equipment shutoff valve to thermostat gas valve (Thermostat-Con- trolled Models), to control valve (Manually- Controlled Models), or to gas control (Re- mote-Ready Models) (see Figures 18 and 19). Apply noncorrosive leak detection fluid to all joints. Bubbles forming show a leak.

5.Correct all leaks at once.

6.Light heater (see Operating Heater, pages 20 and 21 [manually-controlled models] or pages 22 and 23 [thermostatically-controlled mod- els]). Check all other internal joints for leaks.

7.Turn off heater (see To Turn Off Gas to Appli- ance, page 21 [manually-controlled models] or page 23 [thermostatically-controlled models]).

4.

Check all joints of gas supply piping system.

 

Apply a noncorrosive leak detection fluid to

 

all joints. Bubbles forming show a leak.

5.

Correct all leaks at once.

6.

Reconnect heater 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 17).

2.

Pressurize supply piping system by either

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 18 and 19). Apply noncorrosive

leak detection fluid to all joints. Bubbles form-

ing show a leak.

4. Correct all leaks at once.

Pressure Testing Heater Gas Connections

1.Open equipment shutoff valve (see Figure 17).

2.Open main gas valve located on or near gas meter for natural gas or open propane/LP sup- ply tank valve.
