<br />TABLE 6C-31 MINIMUM REQUIREMENTS FOR ALL PACKAGES
<br />COMPONENTS SECTION REQUIREMENTS CHEC~
<br />exterior JoInts & Cracks 606.1 To be caulked, gasketed, weather-stripped or otherwise sealed. V
<br />Interior Joints & Cracks 606.1 All openings in interior surfaces of ceilings and exterior walls must be sealed. V
<br />Sore lit TOp Plates 601'.1 Sole plates ana penetratIons through top plates of extenor walls must be sealed, 1/
<br />Infiltration Barrier 606.1 Infiltration bamer must be installed in exterior walls & raised wood floors. ~
<br />Fireplaces 606.1 Fireplaces must have flue dampers, glass doors and outside combustion air intakes. '----"
<br />Exhaust Fans 606.1 Exhaust fans vented to unconditioned space shall have dampers, except for combustion
<br /> devices with integral exhaust ductwork. - -
<br />Combustion 606,1 Combustion space and water heating systems must be provided with outside combustion air,
<br />Heating eXcept for direct vent appliances. -
<br />Water Heaters 612.1 Comply with efficiency requirements in Table 6-11. Switch or clearly marked circuit breaker (electric)
<br /> or cutoff (gas) must be provided, External or buiR-in heat trap required. - -
<br />Swimming 612.1 Spas & heated pools must have covers (except solar heated). Non-commercial pools must have a
<br />Pools & Spas pump timer. Gas spa & pool heaters must have minimum thennal efficiency of 78%. -
<br />Hot Water Pipes 612.1 Insulation is required for hot water circulating systems, (including heat recovery units) and the first
<br /> 8' of piping from the water heater (or until piping enters an insulated wall or slab). -
<br />Shower Heads 612.1 Water flow must be restricted to no more than 3 gallons per minute at 80 PSIG.
<br />HVAC Duct 610.1 All ducts, fittings, mechanical equipment and plenum chambers shall be mechanically attached,
<br />Construction, sealed, insulated and installed in accordance with the criteria of Section 610.1. Ducts in attics must be -
<br />Insulation & Installation insulated to a minimum of R-6. Air handlers shall not be installed in attics unless in mechanical closets.
<br />HV AC Controls 607.1 Separate readily accessible manual or automatic thennostat for each system. '--
<br />
<br />GENERAl DIRECTIONS:
<br />1, On Table 6C-1 indicate the R-vaIue of the insulation being added to each component and the eIliciency levels of the equipment being lnstaIIed. All R.vaIues and efficiencies instaled roost meet or exceed the minimum values
<br />listed, ComponenIS and equipment neither being added nor renovated may be left blank,
<br />2, ADDmONS ONlY. Determine the percentage of new glass to conditioned floor area in the aMmon as follows. T o1aIthe areas of an glass windows, sliding glass doors and glass door panels. Double the area of an non.
<br />vertical roof glass and add ~ to the previous total, When glass in existing exterior waDs is being removed or enclosed by the add"Ition, an amount equal to the total area 01 this glass may be lMltracted from the total glass area.
<br />Divide the adjusted glass area tolaf by the conditiOned floor area of the addition. Multiply by 100 to get the percent, Fmd the largest glass percentage lJlder which your caJculated pen:entage laHs on Table 6C-2. Prescriptives
<br />are given by the type of glass (Single or Double pane) and the overhang (OH) paired with a shacfing coelfident (SC), For a given glass type and OYe!hang,the minirrun shading coelficienI aIowed is specified. AduaI glass
<br />v.indows and doors previously in the exterior walls of the house and being reirlStafted in the addition, do not have to comply with the overt1ang and shading coelficient requirements on Table 6C-2. All new glass in the add"1tion
<br />must meet the requlrtrI'IInI for one of tht optIona In the glUll percentaga category you Indlcated, Tha ovarllang (OH) dIalanCIlII maaaurtd perpanckularty lnlm tht laca ol1he gIaas 10 a polnt directly under 1he outermost edge
<br />of the over11ilng, '
<br />3, RENOVATIONS ONlY, Replacement glass needs 10 meet the following requirements, AIry glass type and shading coefficient may be U5e!I for glass areas which are under at least a two foot overhang and whose lowest
<br />edge does not extend luI1her than 8 feet from the overhang, Glass areas being renovated that do not meet this criteria mus1 be either singIe-pane tinted, doubIe-pane clear or doubIe-pane tinted,
<br />4, Complete the information requested on the top hall of page 1.
<br />5, Read "Minimum Requirements for Small Additions and Renovations", Table 6C.3, and check all applicable ~ems,
<br />6, Read, sign and date the "Owner/Agent" certlfication statement on page 1,
