Energy Savings Plus Health | INDOOR AIR QUALITY GUIDELINES FOR MULTIFAMILY BUILDING UPGRADES 39 PRIORITY ISSUE 12.0 UNVENTED COMBUSTION APPLIANCES (continued) ASSESSMENT PROTOCOLS (AP) MINIMUM ACTIONS (MA) EXPANDED ACTIONS (EA) • Suggest occupants replace gas-fired unvented space heaters not listed to ANSI Z21.11.2 with a vented appliance or, at a minimum, consider upgrading the heater to a new model consistent with ANSI Z21.11.2. • Inform occupants if any unvented combustion space heaters or vent- free gas fireplaces appear to be oversized for their application. Note: The proper size of a space heater depends on a room's dimensions and its heat loss characteristics. A 5,000 BTU/hour space heater often can be a suitable size for a room with a floor area of 150 square feet. MA 12.3 Advise Occupants on Proper Operation and Maintenance Advise occupants to always consult and follow the manufacturer's printed instructions for proper operation and maintenance. If the manufacturer's instructions are not available, advise or assist occupants in obtaining replacement instructions. Note: The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) can be a source of information to obtain manufacturers' instructions for unvented combustion appliances. Advise occupants that unvented space heaters should not be used in a manner that influences the thermostat controlling the primary heat source, thereby causing the space heater to operate in place of the primary heat source. MA 12.4 Ensure CO Detection and Warning Equipment is Installed Ensure CO detection and warning equipment is installed and located according to NFPA 720 and any applicable local or state requirements.
