Code/Standard Clarication
In multiple locations throughout the SlimFit Boiler Manual, two codes were not referred to with their complete
designation. Please see correct designation below:
• National Fuel Gas Code - ANSI Z223.1/NFPA54
• Natural Gas and Propane Installation Code - CAN/CSA B149.1
Additional Codes/Standards Requirements
Venting/combustion air piping - Installations must provide provisions for 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 Sections
8.2, 8.3, or 8.4 of Natural Gas and Propane Installation Code, CAN/CSA B149.1, or applicable provisions of the local
building codes.
Appliances remaining on an existing common vent - Any improper operation of the common venting system should be
corrected so the installation conforms with the National Fuel Gas Code, ANSI Z223.1/NFPA 54, and/or the Natural Gas
and Propane Installation Code, CAN/CSA B149.1. When resizing any portion of the common venting system, the com-
mon venting should be resized to approach the minimum size as determined using the appropriate tables in Chapter
13 of the National Fuel Gas Code, ANSI Z223.1/NFPA 54, and/or the Natural Gas and Propane Installation Code, CAN/
CSA B149.1.
Vent Termination Locations – the minimum distance from adjacent public walkways, adjacent buildings, openable win-
dows and building openings shall not be less than those values specied in the National Fuel Gas Code, ANSI Z223.1/
NFPA 54, and/or the Natural Gas and Propane Installation Code, CAN/CSA B149.1. Vent and air terminations must be
installed at least 12 inches (0.31m) above grade and snow line. Consideration should be given to avoid possible dam-
age caused by vent plumes and condensate when choosing a venting conguration and location. Maintain a distance
of at least 4 ft (1.22 m) horizontally from, and in no case above or below, unless a 4 ft (1.22m) horizontal distance is
maintained, from electrical meters, gas meters, regulators, and relief equipment.
Minimum Wall Thickness for vent penetration: None
Maximum Wall Thickness for vent penetration: 8 inches
Label all wires prior to disconnection when serving controls. Wiring errors can cause improper and
dangerous operation.
Verify operation after serving.
