vent piping can be routed through the building
and properly terminated. The air intake and
exhaust vent piping lengths, routing and termi-
nation method must all comply with the methods
and limits given in the Venting section.
G. PREVENT COMBUSTION AIR CONTAMINATION
Install intake air piping for the Munchkin Boiler
as described in the Venting section. Do not ter-
minate exhaust in locations that can allow con-
tamination of intake air.
H. WHEN REMOVING A BOILER FROM AN
EXISTING COMMON VENT SYSTEM
At the time of removal of an existing boiler, the
following steps shall be followed with each
appliance remaining connected to the common
venting system placed in operation, while the
other appliances remaining connected to the
common venting system are not in operation.
a. Seal any unused openings in the common
venting system.
b. Visually inspect the venting system for
proper size and horizontal pitch and
determine there is non blockage or
restriction, leakage, corrosion and other
deficiencies which could cause an unsafe
condition.
c. Insofar as is practical, close all building doors
and windows and all doors between the
space in which the appliances remaining
connected to the common venting system
are located and other spaces of the building.
Turn on clothes dryers and any appliance not
connected to the common venting system.
Turn on any exhaust fans, such as range
hoods and bathroom exhausts, so they will
operate at maximum speed. Do not operate
a summer exhaust fan. Close fireplace
dampers.
d. Place in operation the appliance being
inspected. Follow the lighting instructions.
Adjust thermostat so appliance will operate
continuously.
e. Test for spillage at draft hood opening after 5

WARNING
You must pipe outside air to the boiler air
intake. Ensure that the intake air will not
contain any of the contaminants below.
Contaminated air will damage the boiler,
resulting in possible severe personal injury,
death or substantial property damage. For
example, do not pipe intake air vent near a
swimming pool. Also avoid areas subject to
exhaust fumes from laundry facilities. These
areas will always contain contaminants.
