VENT DAMPER INSTALLATION
The vent damper referred to in the following instructions
is the Slant/Fin Corporation vent damper.
This device is design certified by A.G.A. for use ONLY on spe-
cific Slant/Fin Corp. gas boiler models. These boilers must
also be equipped with a label which states that the boiler must
be used with a Slant/Fin Corp. automatic vent damper device
and indicates the proper vent damper model number.
A. INSTALLATION INSTRUCTIONS BEFORE YOU START TO
INSTALL
1. Read this installation manual, the "DANGER" label
attached to the top of the boiler, the "WARNING" on the
wiring diagrams, vent damper carton and operator
cover.
2. Perform pre-installation inspection as required by ANSI
specification Z21.66. (See Vent Damper Instructions.)
3. Select a proper, convenient location for vent damper.
Vent damper may be installed vertical or horizontal on
all models (see figures 1 and 2).
4. Carefully unpack the unit. DO NOT FORCE IT OPEN OR
CLOSED! Forcing the damper may damage the gear
train and void the warranty.
