CHAPTER 1: CODES, SAFETY, AND VENTING SYSTEMS

1.1. APPLICABLE FEDERAL CODES

United States:
NFPA 54/ANSI
Z223.1:
NFPA/ANSI 211:
Canada:
CAN1-B149.1:
B149.2:
The above listed codes contain information for gas vented appliances requiring Category II, III and
IV, vent sizing, location, air space clearances to combustibles and safe installation practices. The
gas vent installer must be familiar with the above codes, as well as Local Codes and Regulations.
WARNING!
All installations of boilers and venting should be done only by qualified venting systems personnel
and in accordance with the manufacturer's recommendations. Installing or venting a boiler or any
other gas appliance with improper methods or materials may result in serious injury or death due to
fire or to asphyxiation from poisonous gases (carbon monoxide is odorless and invisible).
WARNING!
•
For correct installation of vent system, read all of these instructions and refer to the vent pipe
manufacturer's instructions.
•
Failure to use the venting system described in this document will void the manufacturer's
warranty and may result in rapid deterioration of the venting system, creating a potential health
hazard.
•
Faulty vent installation can allow toxic fumes to be released into living areas. This may cause
serious bodily injury or property damage. Improper assembly may also affect vent performance.
•
Install separate vents for forced exhaust appliances and natural draft appliances. A common
vent between natural draft and forced exhaust appliances may cause toxic gases to exhaust
through the natural draft appliance rather than to outside air. Breathing exhaust gases will
cause serious personal injury or death.
