Summary
The Georgia Weatherization Assistance Program (WAP) Manufactured Housing Field Guide was developed to align with the U.S. Department of Energy (DOE) Standard Work Specifications (SWS) for Manufactured Housing Energy Upgrades and to support and promote high quality work. This guide was created through a collaborative effort between Southface Energy Institute, Santa Fe Community College, and other participating DOE Weatherization Training Centers. It includes text and photo guides to assist Retrofit Installer Technicians, Crew Leaders, Energy Auditors, and Quality Control Inspectors with effectively performing the tasks required by the WAP. All sections in this Field Guide follow the requirements set forth by the SWS. All tasks and methods outlined in this Field Guide define measure installation and diagnostic testing best practices that should be followed throughout the state.
Codes and Standards
While the SWS and Georgia Weatherization Manufactured Housing Field Guide will help identify the desired outcomes of energy efficiency measures in a weatherization or home energy upgrade project, they are not a replacement for the codes and/or technical standards mandated by a particular jurisdiction. State, local, or municipal code or ordinance has legal precedence and users should obtain copies of the applicable codes and standards for their jurisdiction before performing the work.

Desired Outcome: Work is completed safely without injury or hazardous exposure
Specification(s): OSHA asbestos abatement protocol 29 CFR 1926.1101 will be followed if vermiculite insulation is present
Assess potential asbestos hazard; if unsure whether material contains asbestos, contact a qualified asbestos professional to assess the material, and to sample and test as needed
If suspected ACM is in good condition, do not disturb
If suspected ACM is damaged (e.g., unraveling, frayed, breaking apart), immediately isolate the area(s)
For suspected ACM that is damaged or that must be disturbed as part of the retrofit activity, contact an asbestos professional for abatement or repair, in accordance with federal, state, and local requirements; only a licensed or trained professional may abate, repair, or remove ACM
When working around ACM, do not:
Dust, sweep, or vacuum ACM debris Saw, sand, scrape, or drill holes in the material Use abrasive pads or brushes to strip materials
Asbestos abatement or repair work should be completed prior to blower door testing; exercise appropriate caution when conducting blower door testing where friable asbestos or vermiculite attic insulation is present to avoid drawing asbestos fibers into the living space (i.e., use positively pressurized blower door testing) unless the material has been tested and found not to contain asbestos

When high/low vents are used, use two metal ducts each having 1 square inch of cross-sectional area for every 4,000 Btuh input. Extend each into the attic above the insulation level. Terminate one vent within 12" of the ceiling, and one vent within 12" of the floor. The vents may be concentric (one inside the other) to save space, so long as the difference between the area of the larger and smaller vents is equal to or greater than the 1 square inch/4,000 Btuh requirement.
If using a single large opening in the ceiling, make the opening total 1 square inch per 3,000 Btuh input.
If high/low vents extend horizontally through a CAZ wall, use vents with 1 square inch of area per 2,000 Btuh of input.
Louvered grilles or doors may be used to connect the CAZ to larger sections of the home to achieve the required volume, but be aware that using this approach has higher potential for creating a carbon monoxide pathway into the home than does creating a sealed CAZ with high/low vents.

The higher a material's perm rating, the more vapor can pass through said material. Drywall typically has a perm rating of approximately 50. For vapor retarders in basements and crawl spaces, SWS calls for materials with a perm rating of <0.1 (which translates to 4mil or thicker). From 2007 IRC definition of vapor retarders: Class I: 0.1 perm (called impermeable), Class II: 0.1 to 1.0 perm (called semi-impermeable), Class III: 1.0 perm to 10 perms (called semi-permeable).

You may need to remove trim to determine what type of sealing is needed at the marriage line. Some original installations use a compressed open-cell polyurethane foam sealing strip with excellent air sealing properties and will need little or no additional work. Other installations may feature fiberglass or other ineffective air sealing measures and require extensive caulking and foaming to reduce air infiltration. Use a blower door to pressurize the house and use smoke to pinpoint leak locations.

Make sure to use a starting collar that is made for the thickness of the duct board you are using. R-6 duct board is 1-1/2" thick. The correct starting collar would therefore have 1-1/2" of solid metal between the shoulder that fits against the outside of the duct board and the base of the tabs.

You may need to cut a slot in the duct board to slide the backer ring through. Use at least three equally spaced screws to fasten the starting collar to the backer ring.

4.1402.2c - Vapor permeability

The higher a material's perm rating, the more vapor can pass through said material. Drywall typically has a perm rating of approximately 50.
In zones 7 & 8 (AK, parts of MN, ND,WI, MI, WY, CO, and ME), vapor retarders should be used to minimize freezing. For vapor retarders in basements and crawl spaces, SWS calls for materials with a perm rating of <0.5 (which translates to 4mil or thicker). From 2007 IRC definition of vapor retarders: Class I: 0.1 perm (called impermeable), Class II: 0.1 to 1.0 perm (called semi-impermeable), Class III: 1.0 perm to 10 perms (called semi-permeable).

Determine in which zone you are working before selecting work materials

In zones 7&8, vapor permeability is undesirable. Use a vapor retarder

Many lightweight wallboard brands have higher perm ratings for humid zones

Materials:
1. Heat tape 2. Zip ties (to attach thermostat) 3. Electrical tape 4. 1/2" thick fiberglass insulation

To prevent pipe freezing and reduce the risk of fire, follow manufacturer's instructions carefully. Choose the proper length heat tape for the pipe to be protected. When using multiple lengths of heat tape on long pipes, start subsequent runs of heat tape one foot before the end of the previous run on opposite sides of the pipe. Never overlap or cross heat tape with itself. Complete heat tape installation instructions may be found here: https://www.foremost.com/mygreathome/mobile-homerepair/seasonal/how-to-install-heat-tape.asp

1
Install thermostat in firm contact with the pipe at the coldest point

2
Fasten heat tape to pipe with electrical tape every six inches.

3
Measure and cut insulation to fit water lines. Miter insulation at elbows and tees

4
Fasten insulation to water lines with zip ties

Before
Uninsulated ducts in unconditioned spaces are an energy drain

After
Properly insulated ducts operate at much higher rates of efficiency

In mixed or hot/humid climates, ensure that ducts are properly sealed, wrapped in insulation, and have an intact, sealed vapor barrier (typically kraft-backed foil or shiny Mylar material) before blowing loose fill insulation over them. The duct wrap and vapor barrier minimizes condensation forming on the ducts.

Best Practice
Best practice is to install on-demand water heaters as direct-vent units

If not installed as direct vent, refer to notes and images on next page for required combustion air

To determine adequate combustion air: add up the input Btus of all combustion appliances in the space and divide by 20. The result is the minimum required air volume in cubic feet (50 cubic feet per 1,000 input Btus). If the available volume is less than 50 cubic feet per 1,000 input Btus, provide additional combustion air as listed below for each circumstance, in accordance with the 2012 IRC G2407.

Testing water supply pressure
Tools: 1. Water pressure gauge
Check manufacturer's specifications for flow and pressure requirements. System pressure may be easily measured with a pressure gauge attached to a hose bib or faucet. Pipe sizing calculations (to ensure adequate flow rates) are best left to a licensed plumber or mechanical contractor.
