Before Installation

Checkup
• Check the fixing brackets and vent pipe yearly for damage or wear. Replace if necessary.
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 Btuh for NRC98-DV,
157,000 Btuh for NRC83-DV.
Check the Power
• The power supply required is 120VAC, at 60Hz.
Using the incorrect voltage may result in fire or electric shock.
Use Extreme Caution if Using With a Solar Pre-Heater
• Using this unit with a solar pre-heater can lead to unpredictable output temperatures and
possibly scalding. If absolutely necessary, use mixing valves to ensure output temperatures do
not get to scalding levels. Do not use a solar pre-heater with the quick-connect multi-system.
Do Not Use Equipment for Purposes Other Than Those Specified
• Do not use for other than increasing the temperature of the water supply, as unexpected accidents
may occur as a result.
Check Water Supply 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.
