C. AUTOMATIC VENT DAMPER
INSTALLATION – GENERAL
1. Do not use one vent damper to control two or more
heating appliances. See Figure 4.2.
2. Follow these and the installation instructions
included with the vent damper. Observe the cautions
and warnings that accompany all instructions.
3. Provide minimum 6 inch (152 mm) clearance
between automatic vent damper and combustible
construction. Increase clearance if required by
vent damper manufacturer’s instructions. Provide
adequate space for vent damper access and service.
4. The automatic vent damper can be mounted directly
onto the draft hood outlet or in vent piping close to
the boiler.
See Figure 4.3 for installation with vent damper
mounted in vertical position. See Figure 4.4 for
installation with vent damper mounted in horizontal
position. Mount the unit to avoid excessive heat on
the operator or condensation drips into the operator.
a. Orient the vent damper operator to facilitate
connection of the vent damper harness to
knockout on right side of boiler. See Figure 6.1.
b. Orient vent damper direction arrow in direction
of vent gas flow. Direction arrow must be visible
from front of boiler.
5. Damper must be in open position when main
burners are operating.
Le registre doit être en position ouverte lorsque le
brûleur principal de l’appareil fonctionne.
D. VENT REDUCER -
GM-e-05 & GM-e-06 ONLY
Install vent reducer with resrictor on outlet of vent
damper. See Figures 4.3 and 4.4.
E. VENT PIPING & CHIMNEY
1. Install vent piping in accordance with Venting of
Equipment part of the National Fuel Gas Code ,
ANSI Z223.1/NFPA 54, sections 7.2, 7.3 or 7.4
of CAN/CSA B149.1, Natural Gas and Propane
Installation Code , or applicable provisions of the
local building codes.
These codes provide design requirements and sizing
tables to provide proper venting and reduce the
potential for condensation and deterioration of the
vent system. Masonry chimneys must be lined with
a clay flue lining or listed chimney lining system.
Exterior masonry chimney applications often require
a listed metal lining system.
2. Inspect the existing chimney and lining for structural
soundness, corrosion and perforations.
3. Do not alter boiler draft hood or place any
obstruction or non-listed damper in the vent system.
4. Before connection of joints, inspect the vent pipe
interior for foreign objects such as tools, equipment,
rags, etc. and remove if present
5. Install vent pipe to slope upward at least 1/4” per
lineal foot (21 mm per meter) between the draft
hood outlet and the chimney.
Installer le tuyau d’évent avec une pente ascendante
minimum de 21 mm au mètre (1/4 po au pied) à la
sortie du coupe-tirage et la cheminée.
6. Secure all joints including flue collar, draft hood,
vent damper, and vent reducer using sheet metal
screws or per listed vent manufacturer’s instructions.
7. Insert vent pipe into but not beyond the inside wall
of the chimney flue.
8. Do not connect vent connectors serving appliances
vented by natural draft into any portion of mechanical
draft systems operating under positive pressure.
9. Support horizontal portions of the venting system
to prevent sagging by use of metal strapping or
equivalent means. Locate supports at no more than
4 foot (1.2 meter) intervals.
Fournir un support à toute portion horizontale du
système d’évacuation à l’aide de courroies de métal
ou une méthode équivalente afin de l’empêcher de
s’affaisser. Placer les supports à des intervalles ne
dépassant pas cent vingt deux (122) centimètres
(4 po), ou en suivant les recommandations d’
installation du fabricant.
