38 Energy Savings Plus Health | INDOOR AIR QUALITY GUIDELINES FOR MULTIFAMILY BUILDING UPGRADES PRIORITY ISSUE 12.0 UNVENTED COMBUSTION APPLIANCES ASSESSMENT PROTOCOLS (AP) MINIMUM ACTIONS (MA) EXPANDED ACTIONS (EA) AP 12.1 Identify Unvented Combustion Appliances and Applicable Regulations Identify any unvented gas or kerosene space heaters or vent-free combustion appliances (e.g., ovens, cooktops, fireplaces). Determine whether any local or state regulations prohibiting these devices apply. Check locations of unvented gas or kerosene space heaters and assess the potential for the unvented heaters to influence the thermostat that controls the primary heat source (e.g., the central heating system). Assess the potential for the space heaters to override the operation of the primary heat source. Determine whether CO detection and warning equipment is installed in dwelling units with unvented combustion appliances. MA 12.1 Ensure Adequate Exhaust and Ventilation in Kitchens Equipped with Gas Cooking Appliances Ensure ASHRAE Standard 62.2-2013 requirements, and any applicable building code requirements, for local exhaust and outdoor air ventilation are met for kitchens equipped with gas cooking appliances. Ensure that kitchen exhaust fans vent directly to the outdoors. See Priority Issue 21.0 Local Exhaust Ventilation for additional guidance. MA 12.2 Remove Unvented Combustion Space Heaters With the occupants' permission, remove any unvented gas or kerosene space heaters that do not conform to local or state regulations. If the heaters are used as the primary source of heat for a space, replace them with electric or vented, code-compliant heating systems. Note: All equipment removals should include proper disposal so that hazardous units are not reinstalled or used elsewhere. With the occupants' permission, remove other unvented heaters, except when used as a secondary heat source and it can be confirmed that the unit is listed to ANSI Z21.11.2. Heaters that are not listed to ANSI Z21.11.2 should be removed prior to the building upgrade, if feasible, but may remain until a replacement heating system is in place. If occupants object to these recommendations: • Provide occupants with information about the hazards of improperly operating unvented space heaters or vent-free appliances including, for example the manufacturers' written instructions and CPSC's Carbon Monoxide Questions and Answers and EPA's Carbon Monoxide's Impact on Indoor Air Quality. The manufacturers' instructions may specify open windows during operation because use of the device requires adequate or additional ventilation to remove products of combustion such as CO, nitrogen oxides, carbon dioxide, particulate matter and water vapor.
