The water heater should never be located in a laundry room or pool facility, for example,
these areas will always contain hazardous contaminants.
To prevent the potential of severe personal injury or death, check for areas and products

If contaminants are found, you MUST: - remove contaminants permanently.
or - relocate air inlet and vent terminations to other areas.

Proper vent installation and type of gas vent or vent connector.
For water heaters for connection to gas vents or chimneys, vent installations shall be in accordance with “Venting
of Equipment,” of the National Fuel Gas Code, ANSI Z223.1/NFPA 54, or “Venting Systems and Air Supply for
Appliances,” of the Natural Gas and Propane Installation Code, CAN/CSA B149.1, or applicable provisions of the
local building codes.
Vent connectors serving appliances vented by natural draft shall not be connected into any portion of mechanical
draft systems operating under positive pressure.
Covering non-metallic vent pipe and fittings with thermal insulation shall be prohibited.
For Category IV venting, the venting system shall be installed in accordance with the water heater manufacturer's
installation instructions.
Non-combustible supports should be placed a minimum of every 4 feet on horizontal portions of the venting sys-
tem to prevent sagging of the venting system. The supports should allow the water heater to be free from strain
and prevent the weight of the venting system from resting on the water heater. The supports should allow for a
¼” (21 mm) slope upwards from the water heater to the termination. This will prevent the accumulation conden-
sate and allow it to drain back towards the water heater and reduce the risk of icing at the termination.
