Utilize elbows when necessary to avoid sharp kinks or excessive bending. For ease of
movement, install with a “lazy” loop. Gas appliance must be disconnected prior to
maximum movement. (Minimum movement is permissible to disconnect gas line.
Cable Restraint
Please refer to the illustration at left when installing cable restraint on all moveable
gas appliances
Eye-bolt is to be secured to the building using acceptable building practices.
Dry wall construction
Secure eye-bolt to a framing stud. DO NOT attach to dry wall only. Locate eye-bolt
at the same height as the gas service approximately 6 in. (150 mm) to either side of
service. Cable restraint must be at least 6 in. (150 mm) shorter than flexible gas line.
INSTALLATION
continued
Couplings and hose should be installed in the
same plane as shown at left. DO NOT OFFSET
COUPLINGS. This results in twisting and undue
torsion causing premature failure.
Correct way to install metal hose for vertical traverse.
Note single, natural loop. Allowing a sharp bend,
shown at right, strains and twists the metal hose to
a point of early failure at the coupling.
Maintain the minimum or larger bending diameter
between couplings for the longest life. Couplings too
close together, as shown at right, create double bends
causing work fatigue failure of fittings.
In all installations where self-draining is not necessary,
connect metal hose in a vertical loop. DO NOT
CONNECT METAL HOSE HORIZONTALLY
unless self-draining is necessary. Then use support on
lower plane as show at left.
