Joining Pipeand Fittings
Fire hazard.
Provide adequate ventilation and do NOT assemble
near heat source or open flame. Do NOT smoke while
using solvent cements and avoid contact with skin or
eyes.
Observe all cautions and warnings printed on material
containers to prevent possible death, personal injury
and/or property damage.
This furnace is approved for venting with Schedule 40 PVC, CPVC,
ABS, Cellular Core pipe fittings and SDR-26 PVC.
NOTE: All PVC, CPVC, ABS, and Cellular Core pipe fittings, sol-
vent cement, primers and procedures MUST conform to American
National Standard Institute and American Society for Testing and
Materials (ANSl/ASTM) standards.
• Pipe and Fittings - ASTM D1785, D2241, D2466, D2661,
D2665, F-891, F-628
• PVC Primer and Solvent Cement - ASTM D2564
• Procedure for Cementing Joints - Ref ASTM D2855
NOTE: In order to create a seal that allows future removal of pipe,
RTV sealant MUST be used on the inlet pipe where it joins to the
furnace. PVC, CPVC, ABS, and Cellular Core pipe and cement
may be used on all other joints.
CAUTION
Do NOT use solvent cement that has become curdled, lumpy
or thickened and do NOT thin. Observe precautions printed on
containers. For applications below 32 ° F., use only low
temperature type solvent cement.
1. Cut pipe end square, remove ragged edges and burrs.
Chamfer end of pipe, then clean fitting, socket and pipe joint
of all dirt, grease, or moisture.
NOTE: Stir the solvent cement frequently while using. Use a natu-
ral bristle brush orthe dauber supplied with the cement. The proper
brush size is one inch.
2. After checking pipe and socket for proper fit, wipe socket and
pipe with cleaner-primer. Apply a liberal coat of primer to in-
side surface of socket and outside of pipe. Do NOT allow
primer to dry before applying cement.
3. Apply a thin coat of cement evenly in the socket. Quickly ap-
ply a heavy coat of cement to the pipe end and insert pipe
into fittings with a slight twisting movement until it bottoms
out.
NOTE: Cement MUST be fluid while inserting pipe. If NOT, recoat
pipe.
4. Hold the pipe in the fitting for 30 seconds to prevent the ta-
pered socket from pushing the pipe out of the fitting.
5. Wipe all excess cement from the joint with a rag. Allow 15
minutes before handling. Cure time varies according to fit,
temperature and humidity.
