• Installation direction of branch pipe
Install the branching pipes so that it branch either
vertically or horizontally.
Both directions
are possible.

Heat insulating for pipes
(Branching Joint)
• In order to prevent dripping at the place where the
insulation provided with the branching kit meets the
insulating material obtained on the site, butt the two
types of insulation up against each other, and then
wrap the seam between the two types of insulation
in at least 10mm of the insulating material (in use
on the site).

by 10mm or more thickness.
• On the gas-side pipe, use insulation that can
withstand heat of 120°C or higher. For the branch
pipe, either use a commercially available coupling
cover (for T-shape) that is at least 10mm thick, or
else insulate the pipe as shown in the figure at
below.
• After applying insulation as outlined above, tape the
insulation in place.
