Before Installation

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-OD, 157,000 Btuh
for NRC83-OD.
Check the Power
• The power supply required is 120VAC, at 60Hz.
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.
5.

Choosing Installation Site

* Locate the appliance in an area where leakage from the unit or connections will not result in damage
to the area adjacent to the appliance or to the lower floors of the structure. When such locations can-
not be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under
the appliance. The pan must not restrict combustion air flow.
• This water heater is for outdoor installation only.
Never install it indoors.
Do not enclose the termination with corrugated
metal or other materials.
This will cause carbon monoxide
poisoning and a potential fire
hazard.
