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
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.
