Buffer Tank Kit
The following images shows the basic layout for attaching the Buffer Tank Kit to a buffer tank. This
process remains the same for all buffer tank sizes. Each buffer tank will require its own Buffer Tank Kit.
The kit supplies all necessary attachments to properly set up your buffer tank as well as proper venting
and draining. Additional line may be required to extend the drain. Adapters may be purchased through
your WoodMaster Flex fuel Dealer for using this buffer tank with 1” Pex line or 1” copper line. The tank
should be installed by a qualified plumber. All Threaded fittings require the used of thread seal tape or
pipe dope.
