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 fi ttings for all Pulse boilers must be UL listed for use

with Category IV, positive pressure, condensing equipment. Specifi 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 fi 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 fl 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 fi tting of
the section below. Attach the sections together. Inspect the joint to
ensure that fl 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 specifi c manufacturers instructions for complete installation
details.

Exhaust Muffl

er Installation

Adhere to the following for muffl

er drain installation:

For muffl

ers installed in the vertical confi guration the drain can be

plugged.

For muffl

ers installed in the horizontal confi 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 muffl

er should be installed as close to the boiler as

possible.
