VENTING INSTALLATION
Breathing carbon monoxide can cause brain damage or death.
Always read and understand the instruction manual.
Install vent system in accordance with codes.
Do not operate water heater if exposed to flooding or
water damage
Special consideration must be taken with installations
above 10,000 feet (3,048 m) refer to high altitude
section of this manual.
Breathing Hazard - Carbon Monoxide Gas
•
•
Do not operate if soot buildup.
•
Do not obstruct water heater air intake with insulating
jacket or blanket.
•
Do not place chemical vapor emitting products near
water heater.
•
Gas and carbon monoxide detectors are available.
•
Never operate the heater unless it is vented to the
outdoors and has adequate air supply to avoid risks
of improper operation, fire, explosion or asphyxiation.
•
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.
