5.3104.9 Inspection Checklist

Potential ACMs will be handled in accordance with SWS 2.0110.2 Potential Asbestos-Containing Materials

The following conditions will be inspected:

• Water, steam, and fuel leaks
• Damaged or missing pipe insulation
• Draft and condensation venting issues (e.g., soot, rusting of flue pipe, burned paint or wires, efflorescence Efflorescence Deposits of crystals or salts left attached to masonry materials after moisture has evaporated off of the surface )
• Corrosion (e.g., rust, mineral deposits)
• General condition of components
• Controls and control settings

For hot water systems, static pressure will be verified

Automatic fill valve will be inspected to ensure it maintains system pressure

If pressure is not maintained, replacement will be made in accordance with the following criteria:

• A backflow preventer will be installed upstream of automatic fill valve if one is not existing
• Automatic fill valve and components will be installed in accordance with manufacturer specifications
• Correct system pressure will be verified

Operation of low water cutoff will be observed by opening blow-off valve

If combustion is not extinguished, remediation will be accomplished by the following procedure:

• Electricity will be disconnected from boiler
• Problem will be diagnosed
• Low water cutoff will be repaired, serviced, or replaced in accordance with manufacturer specifications
• A blow-down valve will be added if not already present
• Boiler will be retested for proper operation

Building/property management team and operations staff will be educated on the correct method to drain the low water cutoff weekly (must drain once per week to remove sediment from float chamber of low water cutoff)

An expansion tank will be installed and operable

Tanks that leak or have excessive corrosion will be replaced and non-bladder tanks will include an expansion tank drain

Tank will be installed in accordance with manufacturer specifications

Expansion tanks will be properly supported with strapping

Tanks that are full of water will be drained and refilled before being replaced or repaired

Expansion tanks with bladders will be pre-charged, minimum to system static pressure, while water is not present in the tank

Bladder tanks that have water inside of the air bladder will be replaced in accordance with manufacturer specifications

The temperature or pressure gauge will be inspected for erosion, cracks or dirt

Damaged temperature or pressure gauges will be replaced in accordance with manufacturer specifications (see SWS 5.3103.7 Installation of Pressure Gauges

Zone valves will be inspected for the following conditions:

• Leaking water
• Not responding to a call for heat

New equipment will be replaced in accordance with manufacturer specifications

Occupant will be informed that air vents have potential to cause moisture problems if not operating properly

Occupant will be reminded to call for maintenance if vents discharge steam or have moisture issues

All homes will have a functioning CO CO Carbon monoxide alarm

If determined to be more than 5 years old, CO CO Carbon monoxide detector/alarm will be replaced

If CO CO Carbon monoxide levels in interior living spaces exceed outdoor levels, potential sources will be investigated and appropriate action taken to reduce them (e.g., have a qualified professional tune, repair, or replace improperly operating combustion appliances; apply weather stripping or conduct air sealing between the garage or crawl space and the home)
