Installation Instructions

MULTIPLE MANIFOLD SYSTEM
For those installations in which the energy load demand is large or the appliances are installed through-
out the structure with long distances from the meter, a multiple manifold system may be used. Elevated
pressure systems are a safe, efficient method of providing for larger BTU load demands while maintain-
ing smaller pipe diameters.
COMBINATION STEEL/CSST SYSTEM (Hybrid)
In a hybrid system, corrugated stainless steel tub-
ing is used in combination with rigid pipe or cop-
per tubing. In lower pressure systems it is often
adv
antageous to use both CSST and rigid pipe to
help minimize pressure drops typically encoun-
tered on systems with high loads and/or long
r
uns.
Pro-Flex® Flexible Gas Piping is
approved for use in combination with all approved fuel
gas-piping materials by using approved pipe threads at the interface.
ELEVATED PRESSURE SYSTEM
In a complete elevated pressure system, corru-
gated stainless steel tubing is used to deliv
er
pressures in excess of 1/2 psi to a pounds-to-
inches regulator positioned directly in front of
each appliance regulator. This is an alternate
method of installation used to minimize pressure
drops typically encountered on systems with high
loads and/or long r
uns
.
