Vent Piping | Burnham SCG specification

a.Wipe the male end of each joint using an alcohol pad to remove any dirt and grease.

b.Align weld seams in pipes and use a slight twisting motion to FULLY insert male end into female end of joint. Ensure bead in male end of pipe is below locking band and rest against the end of the female pipe. Verify the factory- installed gasket is not dislodged or cut.

c.Tighten locking band by HAND with a 5/16” nut driver until snug plus ¼ turn. DO NOT SECURE JOINTS WITH SHEET METAL SCREWS OR POP RIVETS. DO NOT PUNCTURE THE VENT SYSTEM!

d.Once the installation is complete, operate appliance and inspect all joints to ensure that ﬂue gases and/or liquid condensate will not escape.

D.Separate Horizontal Venting System. See Figures 4, 5A and 5B.

Vent Piping –

1.This boiler is supplied with components as standard equipment for installation of the separate horizontal venting system.

2.Do not exceed maximum vent/air intake lengths. Refer to Table 4.

3.Recommended horizontal installation consists of vent being sloped down ¼ inch per foot away from boiler. See Figure 4.

4.Use appropriate designed thimbles when passing through combustible walls (thimble use optional for noncombustible walls). Insert thimble through wall from outside. Secure outside ﬂange to wall with nails or screws, and seal ID, OD and vent holes with sealant material. Install inside ﬂange to inside wall, secure with nails or screws, and seal with sealant material.

5.For noncombustible wall application when thimble is not used, size opening such that bell with locking band attached cannot pass through.

6.Join vent terminal to vent pipe. See Figures 5A and 5B.

7.Insert vent pipe through thimble/opening from outside and join to vent system. Apply sealant between vent pipe and opening/thimble to provide weathertight seal.

Air Intake piping - See Figures 4, 5A and 5B.

8.Locate air intake termination on the same wall as the vent termination if possible, to prevent nuisance boiler shutdowns. However, boiler may be installed with vertical venting and sidewall combustion air inlet or visa versa, if installation conditions do not allow alternate arrangement.

9.Do not exceed air intake length. See Table 4.

10.Use single wall metal or PVC pipe.

a.Air intake pipe diameter is based on boiler size. SCG-3 & SCG-4 uses 3 inch diameter piping. SCG-5 & SCG-6 uses 4 inch diameter piping. SCG-7 thru SCG-9 uses 5 inch diameter piping.

11.Air intake termination must be located:

Horizontal - At least twelve (12) inches above grade plus the expected snow accumulation.

12.Start at collar on burner enclosure (inside boiler jacket) and work towards the air intake terminal.

13.Maintain minimum of ¼ inch per foot slope on horizontal runs. Slope towards air inlet terminal when possible. If not, slope towards boiler.

14.The air intake pipe must be adequately supported with straps or supports no less than ﬁve (5) feet apart on horizontal runs. The complete air intake piping system must be rigid and able to withstand minor impacts without collapse.

15.Inlet air pipe penetration:

Horizontal - Size wall penetration to allow easy insertion of air inlet piping. Seal around pipe with sealant to form weathertight exterior joint.

16.Seal all joints airtight, using silicone caulk or self- adhesive aluminum tape.

17.Install Air Intake Terminal:

Horizontal - Remove four (4) screws from cover plate and remove cover plate from terminal. Insert intake piping into intake terminal collar. Secure terminal to intake piping and seal joint with silicone caulk or self-adhesive aluminum tape. Apply continuous bead of silicone caulk around the back of the intake terminal, approximately ¼ inch from its edge. Push inlet terminal inward until terminal’s back ﬂange is against the wall surface. Secure the terminal with noncorrosive fasteners (stainless steel, brass or aluminum) to the wall. Reinstall the cover plate with four (4) screws. Apply a bead of silicone caulk to perimeter of intake terminal’s back ﬂange to provide a weathertight seal.

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.
