Inlet Air And Exhaust Venting - Harsco Industrial SC-2000 Installation & Owner's Manual

Design and installation of venting
systems should be done only be
qualified and knowledgeable
venting systems personnel and in
accordance with vent system
manufacturer's installation
instructions. Installing a boiler or
vent system using improper
installation methods or materials
can result in serious injury or death
due to fire or asphyxiation.
Before connecting a boiler to a
venting system, it must be
determined whether the boiler is to
be installed in a conventional or
direct vent configuration. In the
US, provisions for combustion air
must be in accordance with NFPA
54/ANSI Z223.1, National Fuel
Gas Code, latest edition, or
applicable provisions of the local
building codes. In Canada,
combustion and ventilation air
openings shall comply with
CAN/CSA B-149.1 Natural Gas
and Propane Installation Code.
For correct installation of vent
system, read all of these
instructions and refer to vent
manufacturer's instructions.
Failure to use a proper vent system
(types and materials), as described
in this manual will void the boiler
warranty and may result in rapid
deterioration of the venting system,
creating a health or life safety
hazard.
Faulty vent installation can allow
toxic fumes to be released into
living areas. This may cause
property damage, injury or death.
