FIGURE 6.

Installation on Combustible Flooring

All units are approved for installations on combustible flooring when installed with NSF leg kit number 9003425205. The installed height of the water heater will increase by 3" when the leg kit is installed.

FIGURE 7.

1.Unit needs to be lifted in a way not to damage unit or laid on it’s side to access the bottom of the legs.

2.Slide leg extension under leg and the bolt up through the bottom hole located in the bottom of the leg.

3.Once in place, screw nut down and secure.

4.Front of leg should line up with front of leg extension as shown to make sure weight of unit is distributed through the leg extension.

Insulation Blanket

Breathing Hazard - Carbon Monoxide Gas

Do not obstruct water heater air intake with insulating blanket.

Gas and carbon monoxide detectors are available.

Install water heater in accordance with the instruction manual.

Breathing carbon monoxide can cause brain damage or death. Always read and understand instruction manual.

Insulation blankets are available to the general public for external use on gas water heaters but are not necessary with these products. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters. The water heaters covered by this manual meet or exceed the Energy Policy Act standards with respect to insulation and standby heat loss requirements, making an insulation blanket unnecessary.

Should you choose to apply an insulation blanket to this heater, you should follow these instructions. See the Features and Components section of this manual for identification of components mentioned below. Failure to follow these instructions can restrict the air flow required for proper combustion, potentially resulting in fire, asphyxiation, serious personal injury or death.

DO NOT apply insulation to the top of the water heater, as this will interfere with safe operation of the draft hood.

DO NOT cover the gas valve, thermostat or the Temperature- Pressure Relief Valve.

DO NOT allow insulation to come within 2” (5 cm) of the burners, to prevent blockage of combustion air flow to the burners.

DO NOT allow insulation to come within 9 inches (23 cm) of floor, (within 2 inches (5 cm) of bottom cover) to prevent blockage of combustion air flow to the burners..

DO NOT cover the instruction manual. Keep it on the side of the water heater or nearby for future reference.

DO obtain new warning and instruction labels from the manufacturer for placement on the blanket directly over the existing labels.

DO inspect the insulation blanket frequently to make certain it does not sag, thereby obstructing combustion air flow.

HARD WATER

Where hard water conditions exist, water softening or the threshold type of water treatment is recommended. This will protect the dishwashers, coffee urns, water heaters, water piping and other equipment.

See the Maintenance Section in this manual for sediment and lime scale removal procedures.

Circulation pumps

A circulating pump is used when a system requires a circulating loop or there is a storage tank used in conjunction with the water heater. See Water Piping Diagrams in this manual for installation location of circulating pumps.

See the Circulation Pump Wiring Diagrams in this manual for electrical hookup information. Install in accordance with the current edition of the National Electrical Code, NFPA 70 or the Canadian Electrical Code, CSA C22.1.

All-bronze or stainless steel circulating pumps are recommended for use with commercial water heaters.
