5.3
INSTALLATION OF GAS SUPPLY
5.3.1
A 3/8" NPT elbow connector is supplied for
connecting the supply line to the appliance inlet
pipe.
5.3.2
Use only new black iron or steel pipes or copper
tubing if acceptable. Check local codes.
Note:
In
USA copper tubing must be internally tinned for
protection against sulfur compounds. Unions in gas
lines should be of ground joint type.
The gas supply line must be sized and installed to
provide a supply of gas sufficient to meet the
maximum demand of the appliance without undue
loss of pressure. Sealants used for natural gas
models as well as propane versions must be
resistant to the action of all gas constituents
including L.P. gas.
Sealants should be applied lightly to male threads
to ensure excess sealant does not enter gas lines.
The supply line should include a manual shut-off
valve and union in the line to allow the appliance to
be disconnected for servicing.
A plugged 1/8" NPT tapping must be installed in the
line. The tapping must be accessible for test gauge
connection and be immediately upstream of the gas
supply connection to the appliance.
All piping and connections must be tested for leaks
after installation or servicing. All leaks must be
corrected immediately.
When testing for leaks:-
a.
Make sure that the appliance control knob
is at the OFF position.
b.
Open the manual shut-off valve.
c.
Test for leaks by applying a liquid detergent
or soap solution to all joints. Bubbles
forming indicate a gas leak.
NEVER USE AN OPEN FLAME TO
CHECK FOR LEAKS.
d.
Correct any leak detected immediately.
