1. Select a location which is level, central to the piping systems served and as close to the vent
and air intake terminals as possible.
2. Accessibility clearances, if more stringent (i.e. larger clearances) than required fire protection
clearances, must be used for the boiler installation. Accessibility clearances may be achieved
with the use of removable walls or partitions.
3. The boiler is approved for installation in closets and on combustible floors. This boiler shall
NOT be installed on carpeting.
4. The clearances shown in Table 2 indicate required clearances per IAS listing. A minimum I"
clearance must be maintained between combustible construction and each of the left, top and
back surfaces of the boiler. A minimum 8"clearance is required on the right side, to allow
room for the inlet air pipe. An 18"clearance must be maintained at a side where passage is
required to access another side for cleaning or servicing, inspection or replacement of any
parts that normally may require such attention. Allow at least 24"at the front and left side and
8"at the top for servicing. No clearances are required to venting or combustion air intake
piping.
5. Equipment shall be installed in a location which facilitates the operation of venting and
combustion air intake piping systems as described in this manual.
6. Advise owner of boiler to keep venting and combustion air intake passages free of
obstructions.
both the venting and combustion air intake piping systems connected to the outdoors must
permit flow through the piping systems without restrictions for the boiler to operate.
7. The boiler shall be installed such that the automatic gas ignition system components are
protected from water (dripping, spraying, rain, etc.) during operation and service (circulator
replacement, control replacement, etc.).
E. COMBUSTION AIR AND VENT PIPE REQUIREMENTS
This boiler requires a dedicated direct vent system. In a direct vent system, all air for
combustion is taken directly from outside atmosphere, and all flue products are discharged to
outside atmosphere.
