INSTALLATION
Installation Codes
The installation must conform with these instructions
and the latest editions of the National Fuel Gas Code
ANSI Z223.1, the National Electric Code ANSI/NFPA
70 and local codes. All boiler installations must con-
form to ASME boiler code. Hot water pipes must be
installed with minimum clearances to combustible
material as required by code.
Installation Base
The boiler should be mounted on a level, non-com-
bustible surface. Boiler must not be installed on
carpeting. The boiler can be installed on a combustible
surface only when a suitable floor shield base is pro-
vided. Raypak offers an optional floor shield base
which can be factory installed on all indoor models
except Model 133; the Model 133 floor shield base is
shipped loose and must be installed by the contractor.
Do NOT use the shipping crate base as an installation
base.
In addition, the boiler shall be installed such that the
gas ignition system components are protected from
water (dripping, spraying, rain, etc.) during appliance
operation and service (circulator replacement, control
replacement, etc.).
Clearances
NOTE: The boiler should be located in an area
where water leakage will not result in damage to the
area adjacent to the appliance or to the structure.
When such locations cannot be avoided, it is
recommended that a suitable drain pan, adequately
drained, be installed under the appliance. The pan
must not restrict air flow.

*Vent includes factory-supplied drafthood and does not include field-
supplied vent systems above the drafthood. On Models 2100-4001
drafthood is built into boiler.
NOTE: For Models 2100-4001, a factory-installed
floor shield is standard. Table B provides the floor
shield ordering information for other models.
