WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,
and strict adherence to applicable
jurisdictional/professional codes and
regulations.
Do not attempt to start boiler to test
wiring before fi lling and purging the
boiler. A dry fi re may cause injury,
boiler damage, and/or property
damage, and is not covered by
warranty.
Do not use the boiler/burner as
support for ducted air piping.
Ducted piping must be supported
independently of the boiler.
Do not terminate venting into an
enclosed area.
Never use open fl ame or smoke from
a cigarette, cigar, or pipe as a testing
method during boiler installation,
operation, or maintenance.
Foreign substances, such as
combustible volatiles in the
combustion system can create
hazardous conditions. If foreign
substances can enter the air stream,
the boiler combustion air inlet must
be piped to an outside location.
Particulate matter or chemicals in the
combustion air supply to the boiler
will cause damage to air fl apper
gaskets, could cause the unit to fail
to light, and is not covered under
warranty.
2. Ensure gas ignition system components are protected from water
(dripping, spraying, rain, etc.) during boiler operation and service.
3. Any attempt to start the boiler to test wiring prior to fi lling and purging
may result in a dry fi re and void the warranty.
Air Intake Supply Piping Installation Preparation
The boiler is equipped with air intake supply and exhaust vent connections
located at the top and rear of the boiler respectively. See Figure 12. Air supply
is on the top. For Models PHW300 and PHW500 these connections are 3” NPT
threaded female fi ttings and for Models PHW750, PHW950, PHW1000, and
PHW1400 they are 4” NPT thread female fi ttings. These fi ttings will accept 3” and
4” male/female pipe to tubing adaptors respectively. Model PHW2000 has 6”
NPT threaded female fi tting. In supporting piping, or routing it through a rafter
or wall, always use vibration eliminating hangers around the piping to prevent
vibration transmission. Always avoid rigid connections between piping and
structural members of the building.
1. For sealed combustion applications, air intake must be piped out of the
building. Air Intake pipes and fi ttings for all models shall be Schedule 40
PVC pipe. All Schedule 40 PVC pipe, fi ttings, primer and cement must
conform with American National Standard Institute and the American
Society for Testing and Materials (ANSI/ASTM standards).
2. For applications using make up air from the boiler room, a minimum of 10’
of venting including the intake muffl er must be installed. Per ASME Section
VI Para. 6.04, an unobstructed air ventilation opening should be sized on
the basis of one square inch free area per 2000 BTU/HR maximum fuel
input of the combined burners located in the boiler room. This is subject to
state and local regulations. The installation of exhaust fans in a boiler room
is not recommended.
