other factors causing the rust & staining makes me suspicious of just galvanic corrosion i've seen similar evaporating MC in commercial from rats or mice using the cable as their highways & byways their urine isn't metallic friendly

some do some don't many ahj's consider R801.3 Roof Drainage In areas where expansive or collapsible soils are known to exist, all dwellings shall have a controlled method of water disposal from roofs that will collect and discharge roof drainage to the ground surface not less than 5 feet (1524 mm) from foundation walls or to an approved drainage system. inapplicable for slab foundations their argument is "foundation walls" slabs don't have walls ahj around here have pretty much adopted the "good ol' boys play along to get along, keep the builders happy & turn land into tax revenue" attitude

not that i'm aware of & recently verified by the ahj the day after my inspection on a new build here source: https://www.ecmweb.com/national-electrical-code/qa/article/20888229/code-qa The rules for securing and supporting Type MC cable can be found in Section 330.30 of the Code. The requirements can be summarized as follows: Type MC cable must be supported and secured by staples, cable ties, straps, hangers, or similar fittings, designed and installed so as not to damage the cable. Type MC cable, with four or less conductors sized no larger than 10 AWG, must be secured within 12 in. of every outlet box, junction box, cabinet, or fitting and at intervals not exceeding 6 ft. Type MC cable must be supported at intervals not exceeding 6 ft. Cables installed horizontally through wooden or metal framing members are considered secured and supported where such support doesn’t exceed 6 ft intervals. Type MC cable can be unsupported where the cable is: 1) Fished through concealed spaces in finished buildings or structures, where support is impracticable, or 2) Not more than 6 ft long from the last point of cable support to the point of connection to luminaires or other electrical equipment within an accessible ceiling. Type MC cable fittings are permitted as a means of cable support.

re: BFF & the same advice i give my family on large purchases & based on the info provided only 2 questions you need answered by you & you alone 1 what is the cost to properly remediate by your chosen vendor 2 is the cost of someone else's problems plus remediation within your financial comfort zone there is no deal until you pull the trigger

S&C those coils are filthy have them professionally cleaned & replace or clean filter more often than what is seen we have compromised grandmonsters & use the higher quality washable type filters in our systems bought two of all sizes needed i clean & swap weekly

much info at the link https://www.suezwatertechnologies.com/handbook/handbook-industrial-water-treatment cooling water systems 26 may be of use although i'm not a proponent; you may want to test the solids & a water sample to identify what it is and pinpoint a course of action because it may not be mold

looks like tectum from mi casa are they sure it's not a retrofit replacement for a previous ceiling

from linked manual Air Shutter Adjustment An air shutter adjusting screw is located on the exterior, bottom of the inner body. Screw air shutter adjusting screw IN to close air shutter top (increase yellow flame). Screw air shutter adjusting screw OUT to open air shutter top (decrease yellow flame). If main burner flame pattern is incorrect, as shown in Figure 19 • See Troubleshooting, page 21

the above statement alone is disgusting... teaching others how to ride on an insurance policy is absurd... relying on this tactic to gain referrals is appalling... to me hth

this must be a border thing it's 1/2 empty on this side of the Red where our lickers cooperate

he resolved as seen in post above yours hth

just keep the hares at bay

Les, tone generator w/probe & or IR has been my go-to & may be the ticket tone gens are cheap & easy to use for the above average bear

classic abridged installation guide requires a return flange flashing @ chimney & sidewall situations either is the closest depicted in the above doc appears snafu from here but most metallics that require flange flashing do imo

yes Jerry damper control lever for combustion/draft fresh air should have been a damper-less screened vent at or above on the adjacent exterior wall
