Potable Water and Space Heating

CAUTION: When this heater is used for both potable water and space heating, observe the following to ensure proper operation.

1.All piping materials and components connected to the water heater for the space heating application shall be suitable for use with potable water.

2.Toxic chemicals, such as used for boiler treatment, shall not be introduced into the potable water used for space heating.

3.If the heater will be used to supply potable water, it shall not be connected to any heating system or components previously used with a non-potable water heating appliance.

4.When the system requires water for space heating at temperatures higher than 140°F, a means such as a mixing valve shall be installed to temper the water in order to reduce scald hazard potential.

Gas Supply

DANGER: Make sure the gas on which the heater will operate is the same type as specified on the heater’s rating plate.

Gas piping must have a sediment trap ahead of the heater gas controls, and a manual shut-off valve lo- cated outside the heater jacket. It is recommended that a union be installed in the gas supply piping adja- cent to the heater for servicing. A pounds-to-inches

ΔT = Temperature rise, °F.

ΔP = Pressure drop through heat exchanger, ft.

SHL = System head loss, ft. (System head loss based on heater and tank placed no more than 5 ft apart and equivalent length pipe/fittings as fol- lows: 2 in. tube = 25 ft; 2 1/2 in. tube = 80 ft.

gpm = Gallons per minute, flow rate.) MTS = Minimum tubing size.

*Must utilize optional cupro-nickel tubes.

**With Hard Water (16-25 grains per gallon), the operating control must be set no higher than 130F for scale free operation. For operating temper- atures above 130F, a water softener must be utilized.
