WARNING
Precautions on Vent Pipe Replacement
The vent system will almost certainly need to be replaced when this appliance is being installed.
Only use vent materials that are specified in this Installation Manual for use on this appliance. Refer
to the “Vent Pipe Installation” section for details. If PVC, CPVC, or Category IV listed pipe is already
installed, check for punctures, cracks, or blockages and consult with the vent pipe manufacturer
before reusing.
Improper venting may result in fires, property damage or exposure to Carbon Monoxide.
Snow Precaution
If this product will be installed in an area where snow is known to accumulate, protect the vent
termination from blockage by snow drifts or damage from snow falling off of roofs.
Check the Gas
Check that the rating plate indicates the correct type of gas.
Check that the gas supply line is sized for 180,000 Btu/h or 199,000 Btu/h.
Check the Power
The power supply required is 120VAC, at 60Hz.
Using the incorrect voltage may result in fire or electric shock.
Do Not Use This Water Heater for Purposes Other Than Those Specified
Do not use for applications other than increasing the temperature of the water supply, as unexpected
accidents may occur as a result.
Check Water Quality
If the water supply is in excess of 12 grains per gallon (200 mg/L) of hardness, acidic or otherwise
impure, treat the water with approved methods in order to ensure full warranty coverage.
