WARNING
Fire Hazard! Do not install on carpeting. Failure to
follow these instructions could result in death or
serious injury.
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.
• Not approved for outdoor installation.
• 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 2 and figures 4-1a - 4-2c.
• Boiler shall be installed on flat vertical wall which is
capable of supporting the weight of the boiler.
• Boiler may be installed in any room or internal space,
special attention shall be given to the requirements
of the current electrical provisions with respect to the
installation of the boiler in a room or internal space
containing a bath or shower. Where a room- sealed
boiler is installed in a room containing a bath or shower,
it must not be possible for a person using the bath or
shower to touch any electrical switch or boiler control
utilizing line voltage electricity.
• Multiple Boilers can be wall mounted, placed side by
