Section 3. Installation Instructions

Risk of carbon monoxide poisoning if adapter is improperly attached. Mechanical connections (such as screws) can cause
cracking and leaks in the adapter. Do NOT drill holes or use screws to connect the appliance adapter to the heater vent body.
Attach with manufacturer's specified adhesive.
Risk of fire or asphyxiation if vent is not assembled according to manufacturer's instructions or if vent parts from different
manufacturers are mixed. Vent parts from different manufacturers ARE NOT interchangeable. Mixing parts from more than one
manufacturer may cause leaks or damage to vent. When installing a vent, pick one manufacturer and be sure that all vent parts
come from that manufacturer and are specified by the manufacturer for your system. Follow manufacturer's instructions and
local and National Fuel Gas Code (U.S.) or CSA B149.1, Natural Gas and Propane Installation Codes (Canada) requirements
carefully during assembly and installation.
4. Install vent pipe so that it can expand and contract freely as
the temperature changes. Support the vent pipe according
to applicable codes and vent manufacturer's instructions.
Pipe support must allow the vent pipe free movement out
and back, from side to side, or up and down as necessary,
without putting a strain on the heater or vent body. It is
recommended to slope the horizontal pipe runs up from the
heater at least 1/4" per foot (2cm/M). Install "Approved"
condensate drains at low points where condensate might
collect. Plumb condensate drains to a drain through hard
piping or high-temperature tubing such as silicone rubber or
EPDM rubber – do not use vinyl or other low temperature
tubing. Follow drain manufacturer's installation instructions.
5. Use an "Approved" firestop for floor and ceiling penetrations.
Use an "Approved" thimble for wall penetrations. Use an
"Approved" roof flashing, roof jack, or roof thimble for
all roof penetrations. Do not fill the space around the vent
(that is, the clear air space in the thimble or firestop) with
insulation. The roof opening must be located so that the vent
is vertical.
6. Vent Termination – Vertical (See
height of vent termination above the roof. Use an "Approved"
vent terminal specified by local and national codes and
your manufacturer's instructions. A roof termination must
be vertical. In Canada, the Vent Cap location shall have
a minimum clearance of 4 feet (1.2M) horizontally from
electric meters, gas meters, regulators, and relief openings.
7. Make sure entire installation is sealed according to approved
standard.
