This manual applies only to venting and combustion air inlet instructions and must be
used with the Model SDH installation manual, Form I-PDH/SDH/PEH/SHH/PXH.
Both manuals are shipped with the heater. If either manual is missing, contact your
distributor before beginning installation. The venting instructions in this manual apply
only to PREEVA ® Model SDH.
Venting must be in accordance with local codes and the National Fuel Gas Code NFPA
54 / ANSI Z223.1 or CAN/CSA B149.1 Natural Gas and Propane Installation Code.
Local requirements supersede national requirements.
All separated-combustion units
MUST BE equipped with both combustion air and
exhaust piping to the outdoors. The unique concentric adapter assembly required with
this heater allows for both combustion air and exhaust piping with only one horizontal
or vertical penetration hole in the building. Concentric horizontal and vertical vent/
combustion air systems are the only venting/combustion air systems approved
for Model SDH.
WARNING
Installation should be done by a qualified agency in accordance with these instructions. The qualified
service agency installing this separated-combustion system is responsible for the installation.
WARNING
Do not use an existing venting system. This heater requires installation of the combustion air/
vent system ordered with the unit, either Option CC6 for a horizontal terminal or Option CC2 for a
vertical terminal. Failure to comply could result in severe personal injury or death and/or property
damage.
The presence of chlorine vapors in the combustion air of gas-fired heating equipment
presents a potential corrosion hazard. Chlorine found usually in the form of freon or
degreaser vapors, when exposed to flame will precipitate from the compound, and go
into solution with any condensation that is present in the heat exchanger or associated
parts. The result is hydrochloric acid which readily attacks all metals including 300
grade stainless steel. Care should be taken to separate these vapors from the com-
bustion process. This may be done by wise location of the combustion air terminal with
regard to exhausters or prevailing wind directions. Chlorine is heavier than air. Keep
these facts in mind when determining installation location of the heater in relation to
building exhaust systems.
