LOCATING HEATER

WARNING: Maintain the minimum clearances shown in Figure 4. If you can, provide greater clearances from floor, ceiling and joining wall.

A wall mounting bracket is included with this heater. An Optional Base Kit (GA4550) may be purchased to allow the unit to be installed away from a wall (see Accessories, page 26). Determine which method is best for your application.

IMPORTANT: Vent-free heaters add moisture to the air. Although this is beneficial, installing heater in rooms without enough ventilation air may cause mildew to form from too much moisture. See Air for Combustion and Ventilation, page 5. If high humid- ity is experienced, a dehumidifier may be used to help lower the water vapor content in the air.

For convenience and efficiency, install heater

•where there is easy access for operation, inspec- tion and service

•in coldest part of room

An optional fan kit is available from your dealer. See Accessories, page 26. If planning to use fan, locate heater near an electrical outlet.
