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
cannot 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.
Check the Gas
• Check that the rating plate indicates the correct type of gas.
Check that the gas supply line is sized
for 194,000 Btuh for this unit.
Check the Power
• The power supply required is 120V AC,
at 60Hz. Using the incorrect voltage
may result in fire or electric shock.
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 hard, acidic or otherwise impure, treat the water with approved methods in
order to ensure full warranty coverage.
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.
Checkup
• Check the fixing brackets and vent pipe yearly for damage or wear. Replace if necessary.

Before Installation
Caution
Caution
• Install the water heater in a location where it is free from obstacles and
stagnant air.
• Consult with the customer concerning the location of installation.
• Do not install the water heater near staircases or emergency exits.
• Avoid places where fires are common, such as those where gasoline,
benzene and adhesives are handled, or places in which corrosive
gases (ammonia, chlorine, sulfur, ethylene compounds, acids) are
present.
Using the incorrect voltage may result in fire or cracking.
