The model number for these drains will be the same as

No change is required for drains manufactured by Zurn. The

For example, in sub-section 15415.2.03.E.11, the model number

For neutralization of the acidic condensate from condensing
boilers and the exhaust flue pipe that connect to these
boilers, use a neutralizer tube for each boiler. Make
neutralizer selection based on tube manufacturer’s sizing chart
and on the expected condensing rate of boilers as published by
the boiler manufacturer

A trap primer valve is required for interior drains that will
likely go dry due to lack of a regular source of water and are
connected directly to the sanitary or storm system.
Trap
primers are not required where there will likely be a regular
source of water. For example, bathrooms, kitchens, etc that
are regularly washed down or have a regular source of water
would not require a trap primer since water regularly enters
the drain. This also may include certain mechanical spaces
such as those with RPZ’s that will have regular discharges of
water. Drains that feed into a sump pit would not require a
trap primer since they are not connected directly to the storm
or sanitary lines. Drains near entrances in the building, fan
rooms, condensing boiler rooms, etc. will not likely have a
regular source of water year round and thus will require a trap
primer. The designer must decide based on location and
potential regular water source which drains are to have a trap
primer and the drawing shall clearly indicate those drains that
are to have a trap primer valve. If a project does not have a
drain type requiring a trap primer, delete those applicable
paragraphs. When a trap primer valve is required for a drain
type not so indicated, the option shall be added to the drain
model number. For example, in sub-section 15415.2.03 E, the
NYCSCA

they come with a 1/2” trap primer tapping that are plugged if
not required.
