WARNING
Crystalline silica may be present in
components of this equipment. Exposure
to crystalline silica may pose signi cant
health hazards, including but not limited to
eye and respiratory system damage. Per the
Centers for Disease Control and Prevention
(CDC) and Occupational Safety and Health
Administration (OSHA), appropriate
Personal Protective Equipment must be
worn to minimize exposure to hazardous
substances. Refer to most current guidelines
o ered by the CDC and OSHA for more
information, including Personal Protective
Equipment recommendations.

CAUTION
To prevent potential water damage, never
leave an open manual air vent unattended.
2-18
4. All common venting arrangements must result in a pressure drop of -0.1"
to 0.0" w.c if not using a draft assist fan. (Consult factory for assistance.)
5. All common venting arrangements must result in a pressure drop of
0.0" to 0.75" w.c. with the use of a draft assist fan. (Consult factory for
assistance.)
6. Variable speed exhaust fan pressure setting should be no more than 0.1"
w.c.
7. Flue vent pipes and ttings for all Pulse boilers must be UL listed for use
with Category IV, positive pressure, condensing equipment. Speci cally
this material is AL294C. Stainless Steel 316L piping is also acceptable.
At 480°F temperature rating, a 5" minimum air space clearance to
combustibles is required. Applicable Federal Codes are NFPA 54/ANSI
Z223.1 National Gas Code and NFPA/ANSI 211 Chimneys, Fireplaces, Vents
and Solid Fuel Burning Appliances. In Canada, refer to the venting section
of CAN/CGA B149.1 and 2. The gas vent installer should be familiar with
these federal codes as well as any local codes and regulations that may
apply. The procedure for adhesive joining stainless steel pipe and ttings
follows:
Do not mix stainless steel pipe with galvanized or other alternatives
for the entire length of the system.
All joints between sections of the vent connector and the vertical
conduit must be sealed with a high temperature sealant or gasket to
prevent any possible leakage of ue gas.
Apply a bead of sealant, about 1/2" in diameter, completely around
the male (without tabs) end of each conduit section or elbow,
between 1/4" and 3/8" from the end of the section. Also run a similar
sized bead down the seam weld of each section, from the edge of
the pipe to the top of the bulge.
Fully insert the male end of the section into the female tting of
the section below. Attach the sections together. Inspect the joint to
ensure that ue gases will not escape. If necessary, apply additional
sealant to any voids. Allow the sealant 24 hours to cure before
operating the boiler.
See speci c manufacturers instructions for complete installation
details.
Exhaust Muffl er Installation
Adhere to the following for mu er drain installation:
For mu ers installed in the vertical con guration the drain can be
plugged.
For mu ers installed in the horizontal con guration, the drain opening
should be at the down slope (6 o'clock) position, and should be piped
to the drain line between the boiler and the condensate drain. For best
sound attenuation, the mu er should be installed as close to the boiler as
possible.
