Service Manual

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 5ft vertical and 3ft horizontal).

Termination must be located to prevent re-circulation of flue gases. Medium to long sweep 90° elbows or

straight exhaust terminal coupling recommended.

Gas Requirements - Gas piping sized adequately, ¾" or larger to heater. 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.

Condensate Requirements - Condensate line needs to slope to a drain at a minimum of ¼" per foot. Make sure

the condensate line does not have the potential to freeze. If using more than one heater and using a common

condensate line, make sure the condensate line is properly sized.

Service/Mechanical Room - Provide adequate space for servicing heater. Leave room to get to the top and

bottom pressure switches as well as enough overhead room to remove the anode rods for

servicing (18" min.).
