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.
