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 5.
• Disposal of condensate. See section 5.
• Drainage of water (or water - antifreeze solution)
during boiler service or from safety relief valve
discharge. See section 6.
• Access to system water piping, gas supply, and
electrical service. See sections 6, 7 and 8
.
• Clearances to combustible materials and service
clearances.
See Table 1 and Figures pg. 15.
•
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.
• Requires fresh air intake piped from outdoors, do not
install where air inlet is dusty or dirty.
•
Install a filter on the air intake if boiler is installed in
dusty or dirty enviroment. A high flow air filter with
minimum air filtratrion of 800 cfm can be placed on the
air intake section of the vent pipe. Boiler performance
at maximum vent length may be impacted when an air
filter is used.
• Use of unregulated gas (well gas) is not manufacturer
recomended with this boiler.

Fire Hazard! Do not install on carpeting. Failure to
follow these instructions could result in death or
serious injury.
!
NOTE: Greater clearances for access should supersede fire
protection clearances.
