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-
v
ided. 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.).

% 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.

Table C: Clearances from Combustible Surfaces
All dimensions are in inches.
Derived from National Fuel Gas Code, Table 6.2.3(a)
*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.
% For Models 2100-4001, a factory-installed
floor shield is standard. Table B provides the floor
shield ordering information for other models.
% Combustible floor shield is required when
boiler is to be installed on a combustible surface. (See
ordering information in Table B.)
% Servicing Clearances: Provide at least 24"
(Models 133-1826), 48" (Models 2100-4001) in front of
unit for removal and servicing of the Controls & Burner
Tray. Provide at least 18" on side opposite water
connections for deliming of Heat Exchanger Tubes.
