Shutoff Valve
1. Disconnect heater with its appliance main
gas valve (control valve) and equipment
shutoff valve from gas supply piping sys-
tem. 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 system by either
using compressed air or opening gas sup-
ply valve.
INSTALLATION
WARNING: Test all gas piping
and connections for leaks after
installing or servicing. Correct
all leaks at once.
WARNING: Never use an open
ame to check for a leak. Apply a
mixture of liquid soap and water
to all joints. If bubbles form, there
is a leak. Correct all leaks at once.
PRESSURE TESTING GAS SUPPLY PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
4. Check all joints of gas supply piping
system. Apply mixture of liquid soap and
water to gas joints. If bubbles form, there
may be a leak.
5. Correct all leaks at once.
6. Reconnect heater and equipment shutoff
valve to gas supply. Check reconnected
ttings 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
using compressed air or opening gas sup-
ply valve.
3. Check all joints from gas supply (see Fig-
ure 18 or 19) to equipment shutoff valve.
Apply a noncorrosive leak detection uid
to all joints. Bubbles forming show a leak.
4. Correct all leaks at once.
PRESSURE TESTING HEATER GAS CONNECTIONS
to all joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light heater (see Lighting Instructions on
page 18). Check all other internal joints
for leaks.
7. Turn off heater (see To Turn Off Gas Ap-
pliance, page 19).
1. Open equipment shutoff valve (see Figure 17).
2. Open gas 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 18 or 19).
