7. Flue gas Venting
7.1-Use Only an approved gas vent category II or IV type PH fabricated from AL29-4C.
The vent shall be sized by a chimney venting specialist or a professional engineer using methods or vent calculations
that are acceptable to National and local Codes having jurisdiction..
Any improper operating of the venting system must be corrected so the installation conforms to both ANSI Z223.1/
NFPA 54 or CAN/CSA B149 gas installation Codes.
When resizing any portion of common venting system, the system shall be resized to approach the minimum size as
determined using the appropriate table in part II of ANSI Z223.1/ NFPA54 gas code and /or CAN/CSA B149. Natural
gas and propane installation Code.
[For Category II – Negative breeching pressure range shall be between 0 to -0.09 inches water column
(0 to 0.22 mbar)]
The boiler requires a vent system that will produce sufficient draft at all time to ensure safe and correct operation of
the boiler. The vent system must exhaust all flue gases to the outside in a safe effective manner.
Any improper sealed venting system could result in carbon monoxide (CO) poisoning. Ensure adequate support and
fastening of the vent system, according to vent manufacturer recommended or supplied instructions for proper support,
fastening and sealing requirements.
Do not use barometric draft control on a positive vent pressure ( Category IV). The vent as sized must exhaust all
flue gas gases to the outside in a safe and effective manner in any case.
When resizing any portion of the common venting system, the common venting system shall be resized to approach
the minimum size as determined using the appropriate tables in Part II of ANSI Z223.1/NFPA54 Blocked vent safety
device is equipped on the burner ( High gas pressure switch).
7.2 Co-Venting – Retrofitting:
At the time of removal of any existing boiler, when is removed from a common vent system, the following steps shall
be performed with the each remaining appliance connected to the common vent in operation and not in operation.
This boiler must not be co-vented with a category I or III appliance.
1) Seal any unused opening in the common venting system.
2) visually inspect the venting system for proper size and horizontal pitch, determine there is no blockage, restriction,
leakage, corrosion and other deficiencies which could cause an unsafe condition.
3) Close all building doors, windows and all doors between the appliances which remain connected to the common
venting system are located and other space of the building. Turn on clothes dryers, exhaust fan at maximum speed
and any appliance not connected to the common vent system, close fireplace dampers.
4) Place in operation each of the appliances installed in the common vent system being inspected. Follow the lighting
instructions. Adjust thermostat so appliance will operate continuously.
5) Test for spillage at the draft hood relief opening near and around the each of the gas appliances after 5 minutes
of main burner operation. Use the flame of the match or candle, or smoke from a cigarette, cigar, or pipe.
6) After determining that each appliance remaining connected to the common venting system properly vents when
tested as outlined above, return all doors, windows, exhaust fan, fireplace dampers and any other gas burning
appliance to their normal positions.
7) Any improper operating of the venting system must be corrected so the installation conforms to both ANSI Z223.1/
