VENTING INSTALLATION
VENTING INSTALLATION
Breathing Hazard - Carbon Monoxide Gas
•
Install vent system in accordance with codes.
•
Do not operate water heater if any part has been
exposed to flooding or water damage.
•
Do not operate if soot buildup is present.
•
Never operate the heater unless it is vented to
the outdoors and has and has adequate air
supply to avoid risks of improper operation,
fire, explosion, or asphyxiation.
•
Do not obstruct water heater air intake with
insulating jacket.
•
Do not place chemical vapor emitting products
near water heater.
•
Analyze the entire vent system to make sure
that condensate will not become trapped in a
section of vent pipe and therefore reduce the open
cross sectional area of the vent.
•
Gas and carbon monoxide detectors are available.
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.
