consideration the following guidelines:

1. Thelocationmustallowforproperclear-

2. Consideralocation where the replace

will not be affected by drafts, air condition-

ing ducts, windows or doors.

3. A location that avoids the cutting of

joists or roof rafters will make installation

easier.

4. An outside air kit is available with this

DRAIN PAN (DP42)

Foroutdoorinstallations,thereplaceenclo-

approved for flashing installations. When

needed, these adjustable terminations may be

Note: In the rare instance there is a problem

with the side driven rain or wind or the chim-

ney is not drafting properly, an ADS-8DM

(Anti-Draft Shield) can be used with round

terminations.

CHASE INSTALLATIONS

Instructions for chase installations are

included with the chase style termination

chosen. In a multiple chase installation, be

sure to provide adequate distance between

terminations to prevent smoke spillage from

oneterminationtoanother.Wesuggestthat

terminations be separated at least 24", center

to center and stacked at a vertical height dif-
