Check the Gas

•  Check that the rating plate indicates the correct type of gas.

•  Check that the gas supply line is sized for 

  199,900 Btuh.

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.

Precautions for Mobile Home Installation

•  Verify that the gas supply type matches the gas type listed on the rating plate. If a gas conversion 

must be done, follow the instructions listed in the manual.

4.

 Before Installation

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.

WARNING

CAUTION

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 installation 

locations cannot be avoided, a suitable drain pan, adequately drained, must be installed under the  

appliance. The pan must not restrict combustion air flow.

As with any water heating appliance, the potential for leakage at some time in the life of the product 

does exist. The manufacturer will not be responsible for any water damage that may occur.

DANGER

Indoor

•  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.
