PART 2 VENTING
It is extremely important to follow these venting
instructions carefully. Failure to do so can cause severe
personal injury, death or substantial property damage.
Use of cellular core PVC (ASTM F891), cellular core CPVC
or Radel® (polyphenosulfone) in venting systems shall be
prohibited.
2.1 GENERAL VENTING GUIDE
Figure 5: Venting Configurations
The Dynaforce® is a category II condensing appliance, up to
99% efficient unit.
• The Dynaforce® may be vented with manufactured
prefabricated UL/ULC listed vents of AL29-4C or 316L
stainless steel or with plastic vent certified to UL/ ULC S636,
such as, IPEX System 636 CPVC, IPEX System 636 PVC
or IPEX System 636 PP as permitted by local jurisdictions.
• The Dynaforce® boiler must be vented and supplied with
combustion and ventilation air as described in this section.
Ensure that the venting and combustion air supply complies
with these instructions regarding the vent system, air
system, and combustion air quality.
•
Provisions for combustion and ventilation air are to be in
accordance with the section “Air for Combustion and
Installation”, Of the National Fuel Gas Code, ANSI
Z223.1/NFPA 54, or clause 8.2, 8.3, 8.4 of “Natural Gas and
Propane Installation Code”, CAN/CSA B149.1.2, or
appliance provisions of the local building codes.
•
The distance of the vent terminal from adjacent buildings,
windows that open and building openings MUST comply
with the latest edition of the National Fuel Gas Code, ANSI
Z223.1, in Canada, the latest edition of CAN/CGA Standard
B149 Installation Code for Gas Burning Appliances and
Equipment.
•
Vent connection is made directly to the flue outlet opening
on the back of the unit.
•
For indoor installations venting must be in accordance with
Part 7, Venting of Equipment, of the National Fuel Gas
Code, ANSI Z223.1, or Section 7, Venting of Equipment
and Air Supply for Appliances, of the CAN/CGA B149,
Installation Codes, or applicable provisions of the local
building codes.
•
Horizontal runs of vent pipe shall be securely supported
(approximately every 4 feet) to prevent sagging and
maintain a minimum upward slope of ¼" per foot from the
appliance to the vent terminal.
•
The weight of the venting system must not rest on the unit.
Adequate support of the venting system must be provided
in compliance with local codes and other applicable codes.
• All connections should be secured and sealed per the vent
manufacturers specifications. When a Positive vent system
is disconnected for any reason, the flue must be
reassembled and resealed according to the vent
manufacturer’s instructions.
•
Do not use an existing chimney as a raceway if another
appliance or fireplace is vented through the chimney.
•
This appliance shall not be connected to chimney flue
serving a separate appliance, designed to burn solid fuel.
2.1.1 CATEGORY II AND CATEGORY IV VENTING
A Category II venting system operates with a negative pressure
in the vent.
The Category IV venting system operates with positive pressure
generated by the internal combustion air fan which operates the
combustion process and also exhausts the flue products from
the building.
• The Category II flues from multiple appliances can be
combined into a common vent, this special venting system
must be engineered by venting manufacturer and to be
approved by local authority.
• The Category IV flues from multiple appliances CAN NOT
be combined into a common vent.
• The Category IV flue must be a dedicated stack.
•
The Category IV Flue appliance must have all vent joints
and seams sealed gas-tight
• The flue products in the vent system will be cooled below
their dew point and form condensate in the flue and must
use AL29-4C, 316L Stainless, S636 CPVC, and S636 PVC
and PPE up to 12” diameter.
• The flue from a Category II and IV vent system must have
a condensate drain with provisions to properly collect,
neutralize and dispose of any condensate that may occur .
2.1.2 VENTING GUIDELINES FOR CATEGORY IV
VENTING
• The installed length of the positive pressure category IV flue
from the appliance to the point of termination, outside of the
building,
must not exceed a maximum of 100 equivalent
feet (30.5M) in length . Depending on diameter and
centerline radius subtract from 7 to 19 feet per 90° elbow
using published data. Subtract half this value for each 45°
elbow.
•
For site conditions exceeding 100 equivalent feet an
engineered vent system approved by the local authority will
be required.
• The flue may terminate either vertically at the roof top or
horizontally on a SIDEWALL. See the information about the
specific vent termination location for recommended location
and clearances.
