In designing
a water heater system, pay special attention to:
oWater Velocity
(See page 12 for Required DegreeRise chart.)
oFactory Supplied Pump
Capacity
(See page 12 for Pump Operation.)oManifold Pipe Size
When using more than one heater
(See page 14 for Common Water Manifold Size for Multiple Water Heater Installation Table.)
oStorage Tank Circulating
Tappings
(See page 14 for Manifold Pipe Size.)oPlacement of Cold Water
Inlet and Building Return
(See Appendix A for Water Heater Piping Diagrams.)oWater Hardness
(See page 13 for Water TreatmentInformation.)
CODES
The equipment shall be installed in accordance with those installation regulations in effect in the local area where the installation is to be made. These shall be carefully followed in all cases. Authorities having jurisdiction shall be consulted before installations are made.
In the absence of such requirements, the installation shall conform to the latest edition of the National Fuel Gas Code, ANSI Z223.1. Where required by the authority having jurisdiction, the installation must conform to American Society of Mechanical Engineers Safety Code for Controls and Safety Devices for Automatically Fired Boilers, ASME
LOCATION OF UNIT
1.Locate the unit so that if water connections should leak, water damage will not occur. When such locations cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the unit. The pan must not restrict combustion air flow.
Under no circumstances is the manufacturer to be held responsible for water damage in connection with this unit or any of its components.
