SECTION 2: BOILER INSTALLATION
STEP 1: LOCATING/SETTING BOILER
Boiler may be installed in an alcove (see dimensions in Figure 2.1). Locate boiler so connecting flue pipe between draft hood and chimney is as short as possible.
Observe the following minimum clearances to combustibles: 18" on sides...alcove at front...28" at top...18" at rear...6" from flue pipe in any direction. Maintain a minimum 1” clearance between hot water piping and combustible materials. Local code requirements may specify greater clearances and must be adhered to.
Remove boiler from carton and set it in position. Install on
FIGURE 2.1: MODEL GB200 BOILER DIMENSIONS
