Section: CONNECT GAS TRAIN PIPING

Connect Gas Train Piping

The CG10 gas burner comes supplied with standard gas
train components that meet Underwriters Laboratory
(UL) and CSD-1 requirements for gas trains. The gas
train is normally shipped as components and must be
assembled and installed at the site.
The gas train is used for both natural gas and propane;
for converting burner, see Propane Conversion
instructions on page 17 .
Verify that the gas train components are not damaged
and all piping and fittings are clean inside and out.
See Figure 10 , Figure 11 and Figure 12 starting on page
16 for typical component layout.
Vent lines – Install vent lines to any gas valve component
that requires atmospheric air pressure to balance a
diaphragm. Vent lines must be run to the outdoors, with
the termination point away from fresh air intakes and
windows. The terminal opening must be fitted with a wire
mesh screen to block insects and other contaminants
from entering the vent and must be mounted in such a
position that water, ice, dirt, or any other foreign matter
cannot infiltrate and block the vent piping. Make sure the
final assembly is anchored securely.
Explosion, Fire, and
Asphyxiation Hazard.
Do not use Teflon tape on gas piping. Damage
to gas valve cutoff seals and valve bodies could
cause gas leaks.
Pieces of tape can be cut loose during
•
installation and lodge in gas valves causing cutoff
seal problems.
Teflon tape 'lubricates' pipe threads, allowing
•
iron pipes to penetrate too deeply into aluminum
valve bodies causing distortion and leakage.
Use only pipe sealant compounds that are
•
resistant to the gas being used.
Explosion, Fire, and
Asphyxiation Hazard.
The orientation of the gas valves may have an
effect on operation and safety. Gas valves shall be
mounted in accordance with their manufacturer's
instructions.
