Vent Guidelines Due to Removal of an Existing Boiler

A.Vent Guidelines Due to Removal of an Existing Boiler

For installations not involving the replacement of an existing boiler, proceed to Step B.

When an existing boiler is removed from a common venting system, the common venting system is likely to be too large for proper venting of the remaining appliances. At the time of removal of an existing boiler, the following steps shall be followed with each appliance remaining connected to the common venting system placed in operation, while the other appliances remaining connected to the common venting system are not in operation:

1.Seal any unused openings in the common venting system.

2.Visually inspect the venting system for proper size and horizontal pitch and determine there is no blockage or restriction, leakage, corrosion, and other deﬁciencies which could cause an unsafe condition.

3.Insofar as is practical, close all building doors and windows and all doors between the space in which the appliances remaining connected to the common venting system are located and other spaces of the building. Turn on clothes dryers and any appliance not connected to the common venting system.

Turn on any exhaust fans, such as range-hoods and bathroom exhausts, so they will operate at maximum speed. Do not operate a summer exhaust fan. Close ﬁreplace dampers.

4.Place in operation the appliance being inspected. Follow the Lighting (or Operating) Instructions. Adjust thermostat so appliance will operate continuously.

5.Test for spillage at the draft hood relief opening after ﬁve (5) minutes of main burner operation. Use the ﬂame of a match or candle, or smoke from a cigarette, cigar or pipe.

6.After it has been determined that each appliance remaining connected to the common venting system properly vents when tested as outlined above, return doors, windows, exhaust fans, ﬁreplace dampers and any other gas burning appliance to their previous conditions of use.

7.Any improper operation of the common venting system should be corrected so the installation conforms with the National Fuel Gas Code, NFPA 54/ANSI Z223.1. When resizing any portion of the common venting system, the common venting system should be resized to approach the minimum size as determined using the appropriate tables in Part II in the National Fuel Gas Code, NFPA 54/ ANSI Z223.1.

B.General Guidelines

1.Vent system installation must be in accordance with National Fuel Gas Code, NFPA 54/ANSI Z221.3 or applicable provisions of local building codes. Contact local building or ﬁre ofﬁcials about restrictions and installation inspection in your area.

2.The SCG is designed to be installed as either a Direct Vent boiler or Power Vent boiler. In the Direct Vent conﬁguration all of the air for combustion is supplied directly to the burner enclosure from outdoors and ﬂue gases are vented directly outdoors (through wall or roof). In the Power Vent conﬁguration, room air provides air for combustion and ventilation. Flue gases are still vented directly outdoors (through wall or roof). Note: Venting requirements change if indoor air is used.

3.Refer to the appropriate drawings in this section of this manual to determine the proper conﬁguration of venting system. See Table 1.

4.This appliance requires a Special Gas Vent. The product is designed to use Burnham supplied

AL 29-4C®Stainless Steel vent system components. The following manufacturers offer similar

AL 29-4C®components and are approved for use with this product. Heat-Fab Inc. - Saf-T-Vent, Flex-L International Inc. - Star-34, Z-Flex U. S., Inc. - Z-Vent, and Protech Systems , Inc.- FasNSeal™ or equivalent. The use of these alternate manufacturer’s venting systems will require adapters to connect

to the Burnham supplied vent connector and vent terminal. These adapters are not supplied with this unit and should be obtained from the supplier of the alternate manufacturer’s venting system. See Table 3 for complete list of Burnham Vent System Components.

5.Horizontal vent pipe must maintain a minimum ¼ inch per foot slope down towards boiler.

6.Use noncombustible ¾ inch pipe strap to support horizontal runs and maintain vent location and slope while preventing sags in pipe. Do not restrict thermal expansion or movement of vent system. Maximum support spacing is ﬁve (5) feet. Do not penetrate any part of the vent system with fasteners.

7.Vent length restrictions are based on equivalent length of vent/air pipe (total length of straight pipe plus equivalent length of ﬁttings). Maximum vent/air lengths are listed in Table 4. Do not exceed maximum vent/air intake lengths. Table 3 lists equivalent lengths for ﬁttings. Do not include vent/ air terminals in equivalent feet calculations.

8.Provide and maintain vent pipe minimum clearances to combustible materials. Vent pipe minimum clearance to combustible material is four (4) inches when vent is installed in a fully enclosed (chase) application or three (3) inches when vent is installed

SCG specifications

Burnham SCG, short for Burnham Smart City Grid, represents a groundbreaking initiative aimed at reshaping urban landscapes through the integration of modern technologies and sustainable practices. Situated in the heart of a growing metropolis, Burnham SCG embodies the principles of smart city design, focusing on creating an efficient, interconnected environment that enhances the quality of life for its residents.

One of the key features of Burnham SCG is its extensive use of Internet of Things (IoT) technology. This infrastructure enables real-time data collection from various sensors strategically placed throughout the city. For instance, smart streetlights equipped with sensors adjust their brightness based on ambient light conditions and pedestrian activity, effectively reducing energy consumption. This use of IoT extends to waste management, where smart bins signal when they are full, optimizing collection routes and minimizing fuel consumption.

In addition to IoT, Burnham SCG places a strong emphasis on renewable energy sources. The city integrates solar panels across public buildings and utilizes wind turbines in designated areas, contributing to a significant reduction in carbon emissions. Furthermore, an advanced battery storage system ensures that excess energy generated during peak production times is efficiently stored and used during high-demand periods, promoting energy resilience.

Transportation in Burnham SCG embraces the future with integrated smart mobility solutions. A robust network of electric vehicle charging stations encourages the adoption of eco-friendly transportation. The city also features a user-friendly app that provides real-time information about public transport schedules, bike-sharing availability, and traffic conditions, making it easier for residents to navigate their daily commute.

The urban design of Burnham SCG prioritizes green spaces and walkability. Urban planners have designed parks and pedestrian-friendly pathways that encourage outdoor activities and community engagement. These green areas not only enhance urban aesthetics but also contribute to improved air quality and biodiversity.

Lastly, community involvement stands at the core of Burnham SCG’s framework. The city regularly engages its residents through public forums and digital platforms, ensuring that their voices are heard in decision-making processes regarding urban development and sustainability initiatives.

In summary, Burnham SCG is a visionary model of a smart city that integrates technology, sustainability, and community engagement. With its innovative features and forward-thinking policies, it sets a benchmark for future urban developments around the world.
