1. A customer wants to install a 10,000 btu unvented room heater in their
bathroom. Would you advice them to do so?: No
2. What type of appliances are constructed so that all air for combustion is
derived directly from the outdoors through one duct or pipe, and all flue gases
are discharged to the outdoors through another duct or pipe.: Direct vent
3. Residential propane appliances categories: Cat 1, 2, 3, and 4
4. Name plates are required when installing a appliance: Listed
5. Unlisted room heaters are prohibited for use in bathrooms if the btu rating
is or less according to code: 6000 btu's
6. Unlisted, gas, food service counter appliances must be at least from any
combustible material: 12 inches
7. Name two factors you must consider when selecting an appliance for a given
application: Venting and combustion air
8. is a measure of thermal resistance used in the building and construction
industry: R value
9. What method of calculating needed combustion air is used when the air
infiltration rate is unкnown: Standard calculation method
10. When determining the air infiltration rate using the КAIR method, the follow-
ing must be determined: Calculate ACH, size combustion air openings, determine building parameters
11. Which method is used when supplying additional air to a structure by creat-
ing two permanent openings in a single room, one on top and one on bottom,
each 12 inches from the ceiling or floor: Two-openings method
12. The three sources for supplying additional air to a structure that is found
to have an inadequate air supply are indoor air, outdoor air, and : Combination
indoor and outdoor air
13. The three types of venting systems are natural draft, direct, and draft
1/9
, venting: Mechanical
14. The two basic ways natural draft systems vent: Through lines masonry chimneys and
metallic gas venting materials
15. In a sealed combustion direct vent appliance: Combustion air is separate from where the
appliance is located, combustion air is obtained from and discharged to the outdoors
