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
floors. 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 4.3.
• 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 figure 4-1.
• Multiple Boilers can be placed side by side, back to back
or wall mounted.
