Product Usage Instructions

1. All models are available in Natural Gas or Propane (LP). For Propane replace the N with P for LP model.

2. Ensure proper clearances: Top – 12 inches, Bottom – 1/2 inch,
   Front – 5 1/2 inches, Sides – 0 inches, Back / From Vent Pipe – 1 inch

3. Refer to the water flow rate curves for accurate sizing of the water heater.

4. For indoor applications, consider the temperature of outdoor intake air.

5. For venting, use 3-in./5-in. (7.6-cm/12.7-cm) UL-approved Category III Stainless Steel vent materials or water heater manufacturer-approved vent material (MetalFab, UBBINK, and Rainbow).

6. The maximum equivalent vent lengths for single-unit installations are as follows:

   • 0 90 Elbows: 43 ft. (13.1 m) straight pipe
   • 1 90 Elbow: 41.5 ft. (12.6 m) straight pipe
   • 2 90 Elbows: 38.5 ft. (12.2 m) straight pipe
   • 3 90 Elbows: 34 ft. (11.7 m) straight pipe
   • 4 90 Elbows: 28 ft. (11.3 m) straight pipe
   • 5 90 Elbows: 20.5 ft. (10.8 m) straight pipe
   • 6 90 Elbows: 11.5 ft. (10.4 m) straight pipe

7. Ensure a minimum vent length of 1 ft (0.3 m) for straight pipe installations.

8. Connect the gas, hot water, and cold water connections using 3/4 NPT fittings.

1. Based on simultaneous showers using 2.5 GPM flow rate pre-mixed with cold water line. Flow rates vary depending on the temperature of incoming cold water and the water heater’s set temperature. Refer to flow rate curves for accurate sizing. 2 For indoor applications, this is the temperature of outdoor intake air. 3 Manifolds with standard RJ11 communication cables. 4 If anti-freeze is on and combustion is on, total W will be 217W (85+132). 5 Recommended 24″ clearance for service.
