SL 28-160 MODULATING GAS BOILER
All venting must be installed in accordance with the requirements of the
jurisdiction having authority: in Canada, Part 8,
Venting Systems
of the B149.1-
10 Code and any other local building codes are to be followed. In the USA
the National Fuel Gas Code, ANSI 223.1, latest edition, prevails. Where there
is a discrepancy between the installation instructions below, and the code
requirements, the more stringent shall apply.
Provisions for the combustion and ventilation air in accordance with the section
“Air for Combustion and Ventilation” of the National Fuel Gas Code, ANSI Z223.1/
NFPA 54, or Clause 8.2, 8.3 or 8.4 of the Natural Gas and Propane Installation
Code, CAN/CSA B149.1, or applicable provisions of the local building codes.
IMPORTANT
When an existing boiler is removed from a common venting system, the common
venting system is likely to be too large for proper venting of the appliances
remaining connected to it.
When re-sizing any portion of the common venting system, the common venting
system should be re-sized to approach the minimum size as determined using
the appropriate tables in the National Fuel Gas Code, ANSI Z223.1 - latest
edition. In Canada, use the B149.1-10 Installation Code.
At the time of removal of an existing boiler the following steps shall be followed
with each appliance remaining connected to the common venting system placed
in operation, while the other appliances remaining connected to the common
venting system are not in operation.
•
Seal any unused opening in the common venting system.
•
Visually inspect the venting system for proper size and horizontal pitch and
determine there is no blockage or restriction, leakage, corrosion and other
deficiencies which could cause an unsafe condition.
•
Insofar as is practical, close all building doors and windows and all doors
between the space in which the appliances remaining connected to the
common venting system are located and other spaces of the building. Turn
on clothes dryers and any appliance not connected to the common venting
system. Turn on any exhaust fans, such as range hoods and bathroom
exhausts, so they will operate at maximum speed. Do not operate a summer
exhaust fan. Close fireplace dampers.
•
Place in operation the appliance being inspected. Follow the lighting
instructions. Adjust thermostat so appliance will operate continuously.
•
After it has been determined that each appliance remaining connected to the
common venting system properly vents when tested as outlined above, return
WARNING
Venting, condensate
drainage, and combustion
air systems for all IBC
boilers must be installed in
compliance with all applicable
codes and the instructions of
their respective Installation
Manuals.
Inspect finished vent and air
piping thoroughly to ensure
all are airtight and comply
with the instructions provided
and with all requirements of
applicable codes.
Failure to comply will result
in severe personal injury or
death.
