First determine the effective length of the gas supply line by measuring the actual length of piping, and then adding 5 ft. for every elbow or “T” to the actual length. Use the charts below to determine the pipe diameter necessary to accommodate the BTU demand of the unit. If there are more gas drawing appliances on the line, size according to the maximum amount of BTU demand. FOR NATURAL GAS Maximum Capacity of pipe in Cubic Feet of Gas per Hour Follow boxed numbers for piping just one 125 HX f

Back 0 inches D. Sides 4 inches (102mm) E. Bottom 12 inches (306 mm) Clearance from vent is dependent upon the clearance rating of the venting material used. For example, type B-a vent is approved for 1 inch clearance. Note: Typically, the minimum clearance to combustible materials should not be less than 6” for single wall flue pipe. Note that this clearance can be reduced if combustible materials are protected as per table VI of the National Fuel Gas Code or if Type B gas vent is used. 6 720 6

insufficient water flow volume to activate the burners at their minimum flow requirement 2. dirt in the water flow valve causing the valve to malfunction 3. sediment buildup in faucet aerators or shower heads 4. uneven pressures between cold and hot (with single lever faucets) 5. plumbing cross-overs These water related problems can cause the heater to deliver less than its full output, or to shut down completely. SPECIFIC PROBLEMS AND ANSWERS Note: Problems are stated in upper case, bold face.

Observe the clearances associated with the class of vent pipe used. FIGURE H Installation - Electrical 1. Route the control cable from the power venter fan along the ceiling or joists down to the gas pressure switch, taking care not to come closer than 6" to the vent pipe or any other potentially hot surface. In many cases, the gas supply piping can be used as a routing path from the ceiling down to the controls, using the supplied nylon ties to secure the cable. 2. Connect the BLUE wire from th
