4 - LOCATING BOILER
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 or alcove provided
it is correctly designed for that purpose and minimum
clearances are met.
• Protect gas ignition system components from water
(dripping, spraying, rain, etc.) during operation and
service (circulator replacement, condensate trap,
control replacement, etc.).
• 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 1 and Figures pg. 11.
•
Boiler shall be installed on flat vertical wall which is
capable of supporting the weight of the boiler.
• Room-sealed boiler installed in a room containing bath
or shower shall be installed so person using bath or
shower cannot touch any electrical switch or boiler
control utilizing line voltage electricity.
• Multiple Boilers can be wall mounted, placed side by
side, or back to back.
• Observe service clearances in all installations.
• For Direct Vent installations, air vents are not required
in room boiler is installed in, or when installed in closet
or compartment.

!
NOTE: Greater clearances for access should supersede fire
protection clearances.
