Sears 9MPD - Manual (Page 27)

NOTE: Stirthesolventcementfrequently whileusing. Usea natu­
ral bristle brush or the dauber supplied with the cement. The prop­
er 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 inside surface of socket and outside of pipe. Do NOT al­
low primer to dry before applying cement.
3. Apply a thin coat of cement evenly in the socket. Quickly
apply a heavy coat of cement to the pipe end and insert
pipe into fittings with a slight twisting movement until it bot­
toms 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.
Connecting Vent Pipes and Termination
NOTE: Combustion air intake and vent MUST terminate in the
same atmospheric pressure zone. If installation is in a cold cli­
mate (sustained temperatures belowO°F), increase the minimum
distance between vent pipe and air intake from 8 " to 18".
CAUTION
Maintain a minimum of 36 ' between combustion air inlet and
clothes dryer vent. Terminate the combustion air intake as
far as possible from any air conditioner, heat pump,
swimming pool, swimming pool pumping, chlorinator or
filtration unit.
FIRE HAZARD
Observe all cautions and warnings printed on material
containers
to prevent possible death, personal injury
and/or property damage.
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.
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 Ameri­
can National Standard Institute and American Society for Testing
and Materials (ANSI/ASTM) standards.
• Pipe and Fittings - ASTM D1785, D2241, D2466, D2661,
D2665, F-891,F-62S
• PVC Primer and Solvent Cement - ASTM D2564
• Procedure for Cementing Joints ~ Ref ASTM D2S55
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 ce­
ment may be used on all otherjoints.
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.

CARBON MONOXIDE POISONING HAZARD
Failure to properly vent this furnace can result in death,
personal injury and/or property damage.
1. Install all couplings, nipples and elbows using proper pro­
cedures for Joining Pipe and Fittings and maintain spac­
ing between vent and combustion air piping as indicated in
Figure 19 through Figure 27 .
Horizontal Termination
1. Cut two holes.
