D. Stainless Steel Venting
WARNING
Asphyxiation Hazard. Follow these instructions
and the installation instructions included by
the original stainless steel venting component
manufacturers, Heat Fab, M&G/DuraVent or
Z-Flex, whichever applicable. Failure to do so
could cause products of combustion to enter the
building, resulting in severe property damage,
personal injury or death. Where a conflict arises
between Heat Fab, M&G/DuraVent or Z-Flex
instructions and these instructions, the more
restrictive instructions shall govern.
Do not mix vent components from listed
manufacturers.
Examine all components for possible
shipping damage prior to installation.
All condensate that forms in the vent must be
able to drain back to the boiler.
1. Components
a. For use on models PHNTM399C and
PHNTM500C, Velocity Boiler Works offers size
4 in. vent pipe and fittings shown in Table 19. It
is the responsibility of the installing contractor
to procure stainless steel vent system pipe and
related components.
b. Alternate listed stainless steel vent system
manufacturers and components are shown in
Tables 20 and 21.
c. Where the use of “silicone” is called for in the
following instructions, use GE RTV 106 or
equivalent for the vent collar. Seal galvanized
combustion air piping sections with any general-
purpose silicone sealant such as GE RTV102.
Seal PVC combustion air piping sections with
PVC cement.
d. Do not drill holes in vent pipe.

2. Field Installation of Stainless Steel Vent
Adapter
(see Figure 22)
a. No adapter is required for stainless steel vent
pipe unless vent diameter is reduced per Table 8.
See Table 19, 20, or 21 for adapters for reduced
vent diameter.

NOTICE
Do not exceed maximum vent/combustion
air system length. Refer to “2. Vent/
Combustion Air Piping” under “A. General
Guidelines” in this section for maximum
vent/combustion air system length.
Use only vent and combustion air terminals
and terminal locations shown in “3. Vent/
Combustion Air Terminals” under “A.
General Guidelines” of this section.
