CHECKING GAS CONNECTIONS
WARNING: Test all gas pip ing and connections for
leaks after in stall ing or serv ic ing. Cor rect all leaks
at once.
WARNING: Never use an open fl ame to check for
a leak. Apply a noncorrosive leak detection fl u id to
all joints. Bub bles form ing show a leak. Correct all
leaks at once.
CAUTION: Make sure external regulator has been
installed between propane/LP supply and appliance.
See guidelines under Connecting to Gas Supply,
Page 9
.
PRESSURE TESTING GAS SUPPLY PIPING SYSTEM
Test Pressures In Excess Of 1/2 PSIG (3.5 kPa)
The appliance and its appliance main gas valve must be disconnected
from the gas supply piping system during any pressure testing of that
system at test pressures
in excess of
1/2 psig (3.5 kPa).
1. Disconnect appliance with its appliance main gas valve (control
valve) and equip ment shutoff valve from gas sup ply pip ing sys tem.
Pres sures in ex cess of 1/2 psig will dam age control valve.
2. Cap off open end of gas pipe where equip ment shutoff valve was
con nect ed.
3. Pressurize supply pip ing sys tem by ei ther opening pro pane/LP
sup ply tank valve for propane/LP gas or opening main gas valve
lo cat ed on or near gas meter for natural gas or using com pressed
air.
4. Check all joints of gas supply pip ing system. Apply non cor ro sive
leak detection fl u id to all joints. Bubbles form ing show a leak.
5. Correct all leaks at once.
6. Reconnect heater and equipment shutoff valve to gas supply.
Check re con nect ed fi ttings for leaks.
Test Pressures Equal To or Less Than 1/2 PSIG (3.5 kPa)
The appliance must be isolated from the gas supply piping system
by closing its equipment shutoff valve during any pressure testing of
the gas supply piping system at test pressures
equal to or less than
1/2 psig (3.5 kPa).
1. Close equipment shutoff valve
(see
Fig ure 14
).
2. Pressurize supply pip ing sys tem by ei ther opening pro pane/LP
sup ply tank valve for propane/LP gas or opening main gas valve
lo cat ed on or near gas meter for natural gas or using com pressed
air.
3. Check all joints from gas meter to equip ment shutoff valve for
natural gas or pro pane/LP sup ply to equip ment shutoff valve
for propane/LP
(see
Figure 15 or 16
).
Ap ply non cor ro sive leak
detection fl u id to all joints. Bub bles form ing show a leak.
4. Correct all leaks at once.
Pressure Testing Appliance Gas Connections
1. Open equipment shutoff valve
(see
Figure 14
).
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 appliance is in the OFF position.
4. Check all joints from equipment shutoff valve to gas control
(see
Figure 15 or 16
).
Apply noncorrosive leak detection fl uid to all
joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Light appliance
(see Operation,
Page 12
)
Check all other internal
joints for leaks.
7. Turn off appliance.
