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.
• Protect gas ignition system components from water
(dripping, spraying, rain, etc.) during operation and
service (circulator replacement, condensate trap, control
replacement, etc.).
• Wall mount only.
• 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 wall mounted, placed side by
side, or back to back.
