4 - LOCATING BOILER
FIGURE 4-1 Clearance to Combustible Materials
4.1
Boiler Location Considerations
Ambient room temperature always above 32°F (0°C) to
•
prevent freezing of liquid condensate.
Approved for installation in closets and on combustible
•
fl oors. Do not install boiler on carpeting.
Protection of gas ignition system components from
•
water (dripping, spraying, rain, etc.) during operation
and service (circulator replacement, condensate trap,
control replacement, etc.).
Floor or wall mounting.
•
Wall must be plumb and capable of supporting boiler
•
weight plus 60 lbs (28 kg). See Table 1.
Floor must be level. Leveling feet allow adjustment
•
up to 1/4" (6 mm).
Wall mounting. See section 4.2.
•
Access to outdoors to meet minimum and maximum
•
pipe lengths for combustion air and vent piping. See
section 6.
Disposal of condensate. See section 6.
•
Drainage of water (or water - antifreeze solution) during
•
boiler service or from safety relief valve discharge. See
section 5.
Access to system water piping, gas supply, and electrical
•
service. See sections 5, 7 and 8.
Clearances to combustible materials and service
•
clearances. See Table 2 and fi gure 4-1.
Multiple Boilers can be placed side by side, back to back
•
or wall mounted.
