perchloroethylene, chlorine, etc.
3B. Venting
Vent Categories:
Mini-Therm JVS is a natural draft
appliance for Category I venting only. JVH is a
fan-assisted product that can be vented vertically in a
properly-designed Category I system, or can be vented
horizontally as a Category III appliance, per this
installation manual.
WARNING
This boiler must be vented in accordance with
Part 7, Venting of Equipment, of the latest edition
of the National Fuel Gas code, ANSI Z223.1 and
all applicable local building codes. In Canada,
follow CAN/CGA B149 Installation codes.
Improper venting of this appliance can result in
excessive levels of carbon monoxide which can
result in severe personal injury or death!

CGA B149 codes d'installation. Une mauvaise
ventilation de cet appareil peut entraîner des
niveaux excessifs de monoxyde de carbone qui
peut entraîner de graves blessures ou la mort!
The boiler vent collar must be fastened directly to
an unobstructed vent pipe with rustproof sheet metal
screws no longer than 1/2” (13mm) and located to
prevent interference with the inducer damper.
Do not weld the vent pipe to the boiler collar. The
weight of the stack must not rest on the boiler. The
boiler top must be easily removable for normal boiler
service and inspection.
IMPORTANT
Only JVH (induced draft) models may be side-wall
vented per Section 3D without the addition of a
properly sized and installed power venter.
JVS must be connected only using Category Type
I methods and materials per Section 3C. JVH may
be connected per Category I or III (See Section 3D)
methods and materials. See fuel gas code for more
information regarding your venting application.

Avoid terminating boiler vents near air conditioning
or air supply fans. The fans can pick up exhaust
flue products from the boiler and return them to the
building, creating a possible health hazard.
Avoid oversized vent pipe or extremely long runs
