VENTING INSTALLATION INFORMATION

TWIST LOCK PIPES

When using twist lock pipe it is not necessary to use

sealant on the joints.

To join twist lock pipes together, simply align the beads of

the male end with the grooves of the female end, twisting

thepipeuntiltheangeonthefemaleendcontactsexter-

nalangeonthemaleend.Itisrecommendedthatyou

secure the joints with three (3) sheet metal screws, how-

ever, this is not mandatory with twist lock pipe. Figure 9

NOTE: Sealant is not required to assemble replace

venting. Do not use silicone sealant at the inner ue

exhaust connections.

To make it easier to assembly the joints, we suggest put-

ting a lubricant (Vaseline or similar) on the male end of the

twist lock pipe prior to assembly.

HOW TO USE THE VENT GRAPH

The Vent Graph should be read in conjunction with the

following vent installation instructions to determine the re-

lationshipbetweentheverticalandhorizontaldimensions

of the vent system.

1.Determine the height of the center of the horizontal

vent pipe exiting through the outer wall. Using this di-

mension on the Sidewall Vent Graph, Figure 10, locate

the point intersecting with the slanted graph line.

2. From the point of this intersection, draw a vertical line

to the bottom of the graph.

3.Select theindicateddimension,andposition there-

place in accordance with same.

EXAMPLE A:

Iftheverticaldimensionfromtheooroftheunitis11’(3.4

m)thehorizontalruntothefaceoftheouterwallmustnot

exceed 14’ (4.3 m).

EXAMPLE B:

Iftheverticaldimensionfromtheooroftheunitis7’(2.1

m),thehorizontalruntothefaceoftheouterwallmustnot
