SECTION 2 PHW-IOM-2013-0214 INSTALLATION
2-5
American National Standards Institute (ANSI) National Fire Protection
Association (NFPA) 70, latest edition.
4. Install so that all system components are protected from water (dripping,
spraying, rain, etc.) during boiler operation and service.
5. Install on a level, non-combustible surface in the vertical position. Concrete
is strongly recommended.
6. Provide combustion and ventilation air in accordance with applicable
provisions of local building codes or: USA – NFPA 54/ANSI Z223.1, Section
5.3, Air for Combustion and Ventilation.
7. Locate the boiler so that the air supply and exhaust piping between
the boiler and outside wall/roof are within length or pressure drop
requirements. See Clearances and Serviceability section of this manual.
Clearances and Serviceability
Adhere to the following for clearances and serviceability:
1. All local and national codes (NFPA, ANSI, UL, ETL, ASME, CSA) must be
followed for proper clearances and serviceability for your boiler or heater.
Authorities having jurisdiction should be consulted before installations are
made.
2. Appropriate front, back, side and top clearances must be maintained
(Figure 2, Table 1). This will allow access around the equipment to facilitate
maintenance and a safe work environment. An 1 inch (25.4 mm) side
clearance is acceptable between boilers. Custom con gurations may not
allow 1 inch (25.4 mm) side clearance.
3. Ensure all labels on the boiler will be fully visible for maintenance and
inspection.
Install Isolation Mounts
All pulse combustion boilers must be installed with vibration isolators. No
pulse combustion boiler shall be lagged directly to the concrete  oor due to
the transfer of vibration. For installations near “sensitive” areas such as o ces,
classrooms, or hospital rooms, spring mounts - which  t under the corner of each
boiler - must be used instead of the cubes.
¡ How to Install Elastomer Cube Isolation Mounts
Adhere to the following for elastomer cube isolation mounts (see Figure 3):
1. Locate in the box of trim shipped with each Pulse boiler the 4 elastomer
cubes (3” x 3” x 2”) used for vibration isolation.
2. Insert these cubes under each foot of the boiler.
! WARNING
Do not install this boiler in an uncontrolled
environment where condensate will be
subject to freezing temperatures.
4 CAUTION
Do not install this boiler on carpeting.
Install boiler such that gas ignition system
components are protected from water
(dripping, spraying, rain, etc.) during boiler
operation and service.
