When making ABS joints, pieces can be prepared with a cleaner. When joining ABS to PVC matedals, use PVC

solvent cement. Refer to this procedure as specified in ASTM D3138.

Canada Only - In some provinces, PVC primer must be purple in color, PVC solvent cement must be grey, ABS solvent cement must be yellow and PVC solvent cement used when joining ABS to PVC must be white.

Pipe used for exhaust and intake lines should be sized ac- cording to table 4. Note that maximum length of vent pipe is for one run; either intake or exhaust. Maximum vent

length given is not the total length of intake plus exhaust vents.

Each 90° elbow is equivalent to 5 feet (1.52 m) of vent pipe. Two 45° elbows are equivalent to one 90° elbow. One 45° elbow is equal to 2.5 feet (.76 m) of vent pipe.

If intake and exhaust piping runs are not equal in length and number of elbows, the larger diameter pipe must be used for both runs.

NOTE - When a WTKX terminaUon kit (30G79) is installed as part of the intake and exhaust piping, add twelve feet to the equivalent length (the two 2 inch diame- ter 90° elbows end the 27 inch pipe in the kit).

For 75 kBtuh units, connections are provided for 2 inch diameter venting which should satisfy most venting re- quirements. No transition pieces are provided or needed for 2 inch venting.

NOTE - Min. pipe for G32-125 is 5 feet and 2 e/bows of 2 inchdiameter pipe.

For -100and -125 kBtuh units, the intake connection is sized for 3 inch diameter pipe. The exhaust connection has a 2 inchnipple,A pipe transitionpiece is shippedwith the unitto connectto 3 inchpipe. See figure 7 for 2 inch and 3 inch venting applications.

Most venting applicationswill require 3 inch venting for proper unitoperation.For no reason should the intake

and exhaust pipe be different diameter pipes. Re- gardless of the diameter of pipe used, the standard roof and wail terminations described in Intake and Exhaust

Piping Terminations sectionshouldbe used.Exhaustpip- ingmust terminatewith 1-1/2 inchpipefor 1-1/2inchor 2 inchventing and 2 inch pipe for 3 inch venting.
