VENT DAMPER INSTALLATION
The vent damper referred to in the following instructions is the
Slant/Fin LTD/LTEE vent damper.
A. This device is design certified by C.G.A. for use ONLY on
specific Slant/Fin gas boiler models. These boilers must
also be equipped with a plate which states that the boiler
must or may be used with a Slant/Fin automatic vent
damper device and indicates the proper vent damper model
number. This device cannot be used with a millivolt ignition
system.
B. INSTALLATION INSTRUCTIONS BEFORE YOU START TO
INSTALL
1. Read this installation manual, the "DANGER" plate
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 or CSA B149.1-00 for natural gas
and propane.
3. Select a proper, convenient location (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.
WARNING—DANGER
Once you have begun vent damper installation procedure, DO
NOT restore electric power and gas supply until installation
and inspection have been completed (in order to prevent the
main burners from operating). DO NOT operate the boiler until
the vent damper harness "FEMALE PLUG" is plugged into
"MALE PLUG" (as described in the installation instructions),
and the vent damper installation and checkout procedures
have been completed. Failure to observe this warning may cre-
ate a hazardous condition that could cause an explosion or
carbon monoxide poisoning.
C.1. This device must be installed after the appliance draft
hood (between the draft hood outlet and the connector
to the outdoor chimney or vent) as close to the draft
hood as practicable, and without modification of the
draft hood or the damper. (See figures 4 and 5.)
2. The inlet size of the vent damper must be the same
nominal trade size as the outlet of the draft hood.
3. This device must be located in a venting system or sec-
tion of a venting system so that it serves only the single
appliance for which it is installed. (See fig. 8.)
4. Clearances of not less than 152 mm (6 inches) must be
maintained from combustible materials, with provisions
for access for service.
D. NOW, PROCEED AS FOLLOWS:
1. Separate the vent pipe directly on top of the draft hood
or diverter and place damper in position as shown in
figures 4 - 9. The vent damper must be installed so that
the damper position indicator is in a visible location
after installation. See figure 7 for position indicator
description. The arrow imprint on the damper should
point in direction of vent gas flow (towards chimney).
Re-assemble the vent piping. Be sure the vent damper
is well seated and fastened with 3 sheet metal screws.
Screws should be no longer than 13 mm (
figure 9.
2. Be sure that undersized vent pipe does not block
movement of damper vane (see figure 7).
