System 1738 Installation Methods 17
1) ASSEMBLE
Before beginning, assemble
proper materials for the job:
(System 1738 cement and primer (if
required), appropriate applicator
for the size of pipe and fittings
to be assembled, tape measure,
contrasting color marker and
Reed DEB4 beveling tool).
Solvent Welding Preparation Guidelines
2) MARKING THE CUT
Measure the fitting socket depth and mark the outside of
the pipe with this dimension followed by a second mark
1 inch further back. The first line will provide a guide for
ensuring enough solvent cement is applied on the pipe.
Maintaining a 1 inch distance to the second line once the
pipe is inserted into the fitting socket will indicate full and
proper insertion of the pipe inside the fitting socket.
Use proper Personal Protective Equipment (PPE)
for the job: respirator, safety glasses, gloves and
protective clothing.
CAUTION
3) CUTTING THE PIPE
It is important to cut the pipe squarely. A square cut
provides the surface of the pipe with the maximum
bonding area. Pipe can be easily cut with a wheel-type
plastic tubing cutter, chop saw or fine toothed saw. Do
not use reciprocating saws. Tools used to cut pipe must
be designed for System 1738 piping and must be in good
condition in accordance with the tool manufacturer’s
recommendations. If there is any indication of pipe
damage or evidence of pipe end cracking, cut off at
least 2 inches beyond any visible crack. Use of ratchet
cutters is not recommended as they may split the pipe if
not properly used and maintained.
4) PREPARING PIPE ENDS
After cutting, always remove all burrs and filings from
both the inside and outside of the pipe and bevel the
pipe end using a Reed DEB4 beveling tool. Remove
burrs and filings from the inside of the pipe using a knife
edge or file. Failure to remove burrs can scrape channels
into pre-softened surfaces, create obstructions inside
surface walls, or inadvertently plow cement out of the
joint during assembly.

Chop saws will produce shavings inside the pipe which
must be removed. Failure to do so may compromise
the performance of the appliance and venting system.
