Water Heater Installation Checklist
Product Handling
Carefully uncrate the heater. Move in place with a hand truck (DO NOT use the
venting pipes for handles).
Electrical Requirements
Make sure there is 120 volts line voltage. Line voltage must be properly polarized.
Adequate ground supplied to the heater.
Venting Requirements
All venting must stay within the required lengths and diameter (see table below).
Proper support of the venting pipe is a MUST (every 5 ft (1.5 m) vertical and 3 ft (.92
m) horizontal). Termination must be located to prevent re-circulation of flue gases.
Gas Requirements
Gas piping sized adequately, 3/4". Install a properly sized regulator (if unknown,
assure an adequate volume of gas is available). 7" W.C. is required when the unit is
running. Gas pressure must stay below 14" W.C. static pressure. Pressure drops
between static pressure and operating flow should be less than 3" W.C.
Service/Mechanical Room
Provide adequate space for servicing heater. Leave enough overhead room to
remove the anode rods for servicing (18" min).
