4 - LOCATING BOILER

4.1 Boiler Location Considerations

• Ambient room temperature always above 32°F (0°C) to

prevent freezing.

• Approved for installation in closets.

• Protect gas ignition system components from water

(dripping, spraying, rain, etc.) during operation and

service (circulator replacement, 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.

• 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 1 and ﬁgure 5.

• The boiler must not be installed on carpeting.
