WARNING
For correct installation of your venting sys-
tem, read all of these instructions and refer
to the vent pipe manufacturer's instructions.
Failure to use a proper venting system will
void the manufacturer's warranty and may
result in rapid deterioration of the venting
system, a potential health hazard.
Faulty vent installation can allow toxic
fumes to be released into living areas. This
may cause serious bodily injury or property
damage. Vent performance may also be af-
fected by improper assembly.
Install separate vents for forced exhaust
appliances and natural draft appliances.
A common vent between natural draft and
forced exhaust appliances may cause toxic
gases to exhaust through the natural draft
appliance rather than to the outside air.
Breathing exhaust gases will cause serious
personal injury or death.
!
WARNING
All installations of boilers and venting should
be done ONLY by a qualifies expert and in
accordance with the appropriate manual. In-
stalling or venting a boiler or any other gas
appliance with improper methods or materi-
als may result in serious injury or death due
to fire or asphyxiation from poisonous gases
such as carbon monoxide which is odorless
and invisible.
