public heig

ht requirement of 8 feet above the floor.

2. The proposed mounting location allows for the minimum required safe distances from combustibles (combustibles

clude vehicles, wood gasoline and flammable objects, liquids

vapors)

and

3. The proposed mounting location of the heater will not restrict motion of passageway doors or windows.

4. The proposed location will not interfere with operation of the overhead garage door.

5. The proposed location will provide the best coverage of the total area to be heated.

6. The proposed location must provide for adequate combustion

d ventilation air.

7. The proposed location must provide for adequate accessibility

rance for service and proper operation.

clea

8. Consideration be given to the types of vehicles that will be parked in the garage (cars, vans, boats, RV’s etc.).

9. The proposed location will allow for the minimum required

fe distances from combustibles with respect to the vehicles

ked in the garage.

par

10. The proposed location will allow the required utilities (i.e.: gas
